    Strafsache Strohhalm : was Verbote von Einweg-Kunststoffprodukten wirklich bringen ; Fakten, Standpunkte, Analysen (2022)
    Mannheim : Röchling Stiftung
    Details
    Publication Date: 2022-02-23
    Description: Seitdem Einweg-Plastikartikel wie Kunststofftüten und Strohhalme verboten wurden, sind Straßen und Strände sauberer geworden. Zudem wurde auch die öffentliche Diskussion über nachhaltigen Konsum intensiviert. Die Gesamtmenge an Kunststoff-Abfällen ließ sich mit "Plastikverboten" hingegen nicht signifikant reduzieren. Zu diesem Ergebnis kommt der vorliegende Polyproblem-Report der gemeinnützigen Röchling Stiftung und des Beratungshauses Wider Sense in Zusammenarbeit mit dem Wuppertal Institut. Die Autor*innen haben die Wirkung staatlicher Verbote von Einweg-Plastikprodukten unter die Lupe genommen und die Erfahrungen aus Deutschland, Kenia und Kalifornien analysiert.

    The circular economy and digitalisation - strategies for a digital-ecological industry transformation : a study commmissioned by Huawei Technologies Germany GmbH (2022)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-01-26
    Description: Within the Shaping Digitalisation project, we aim to highlight and discuss the opportunities that digitalisation can bring to Germany. In particular, we are discussing three stand-out areas where action is most needed to achieve ecological transformation: mobility, the circular economy, and agriculture and food. This report addresses the second area in need of action. Up until now, discussions on the circular economy have been limited to recycling and the re-use of materials. We must expand the scope of these discussions to include new, resource-efficient business models and the comprehensive transformation of value chains and industrial structures. Our analysis has found that digitalisation is indispensable for this transformation if used properly. We hope this report will provide the impetus needed to kick-start a climate- and resource-friendly industrial transformation in Germany. Here, we have incorporated the findings of our interdisciplinary workshop on "Shaping the Digital-Ecological Industrial Transformation - Business Models and Political Framework Conditions for Climate and Resource Protection" that was attended by experts from international research institutes, civil organizations, public authorities, and private companies.

    Digital product passport : the ticket to achieving a climate neutral and circular European economy? (2022)
    Cambridge : University of Cambridge Institute for Sustainability Leadership
    Details
    Publication Date: 2022-10-10
    Description: The introduction of a Digital Product Passport (DPP) is an opportunity to create a system that can store and share all relevant information throughout a product's life cycle. This would provide industry stakeholders, businesses, public authorities and consumers with a better understanding of the materials used in the product as well as their embodied environmental impact. With the COVID-19 pandemic, the Russian invasion of Ukraine and the cost-of-living crisis, now is a critical moment to transform our economic and business models, while also addressing the huge scale of material emissions. DPPs can be a pivotal policy instrument in this goal. Furthermore, DPPs can accelerate the twin green and digital transitions as part of EU efforts to deliver positive climate action and sustainable economies. In 2020, the European Commission (EC) adopted a new Circular Economy Action Plan (CEAP), which emphasised the need for circular economy initiatives to consider the entire life cycle of products, from the production of basic materials to end-of-life disposal. The Circular Economy Package published in March 2022 includes a proposal for an Ecodesign for Sustainable Products Regulation (ESPR), which builds upon the Ecodesign Directive that covers energy-related products. A DPP will form a key regulatory element of the ESPR by enhancing the traceability of products and their components. This will provide consumers and manufacturers with the information needed to make better informed choices by taking their environmental impact into consideration. As discussed in the report, there is widespread agreement amongst business leaders that a well-designed DPP could have both short- and longer-term benefits, improving access to reliable and comparable product sustainability information for businesses, consumers and policymakers. A well-designed DPP can unify information, making it more readily accessible to all actors in the supply chain. This will support businesses to ensure an effective transformation towards a decarbonised industry. It could also create incentives for companies to make their products more sustainable, as improving access to reliable and consistent information across supply chains will make it easier for customers to make comparisons.

    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-10-24
    Description: A main goal of this study - which also functions as deliverable 210078-D07 of the Circular Economy Beacons (CEB) project - is to evaluate currently available frameworks that measure and operationalise Circular Economy (CE), with a particular focus on the urban context. The regional focus lies on the Western Balkan region, which is at the centre of the project. Such "Urban Circularity Hotspot Frameworks" (UCHF) aim at providing decision support for policy makers, companies, citizens etc. regarding the transition to CE within cities. Based on the analysis of different frameworks, suggestions are derived regarding UCHF suitable for the specific characteristics of Western Balkan municipalities, i.e. a Circular Economy Beacons Urban Circularity Hotspot Framework (CEB-UCHF) ready for short-term implementation.

    Accelerating circular economy solutions to achieve the 2030 agenda for sustainable development goals (2022)
    Details
    Publication Date: 2022-10-24
    Description: Circular economy seems a vital enabler for sustainable use of natural resources which is also important for achieving the 2030 agenda for sustainable development goals. Therefore, a special session addressing issues of "sustainable solutions and remarkable practices in circular economy focusing materials downstream" was held at the 16th International Conference on Waste Management and Technology, where researchers and attendees worldwide were convened to share their experiences and visions. Presentations focusing on many key points such as new strategies, innovative technologies, management methods, and practical cases were discussed during the session. Accordingly, this article compiled all these distinctive presentations and gave insights into the pathway of circular economy towards the sustainable development goals. We summarized that the transition to circular economy can keep the value of resources and products at a high level and minimize waste production; the focus of governmental policies and plans with the involvement of public-private-partnership on 3Rs (reduce, reuse, and recycle) helps to improve the use of natural resources and take a step ahead to approach or achieve the sustainability.

    Business model innovations for renewable energy prosumer development in Germany (2022)
    Details
    Publication Date: 2022-10-24
    Description: In Germany, the number of renewable energy prosumers has increased rapidly since 2000. However, the development of prosumers has faced and will continue to face various economic, social, and technological challenges, which have triggered the emergence of a number of innovative business models (BM). This paper enriches the empirical basis for prosumer-oriented BMs by investigating two BM innovations in Germany (P2P electricity trading and aggregation of small-size prosumers) drawing on business model and socio-technical transition theories. A mix of qualitative data collection methods, including document analysis and semi-structured expert interviews, was applied. We found that while both BMs can potentially address the challenges associated with renewable energy prosumer development in Germany, small-scale prosumers’ participation in both BMs has been limited so far. We identified various internal and external drivers and barriers for scaling up these BMs for prosumer development in Germany. Despite these barriers, both aggregation and centralized P2P targeting prosumers may potentially be also taken up by incumbent market actors such as utilities. Decentralized P2P on the other hand still faces significant internal and external barriers for upscaling. Based on the analysis, the paper provides policy recommendations with respect to the identified drivers and barriers. From a theoretical perspective, our findings provide further evidence to challenge the dichotomous understanding of niche actors and incumbents, the latter of which are often theorized to be resistant to radical innovations.

    Way out of the one-way? : Effects of the COVID-19 pandemic on the generation of waste from packaging in Germany (2022)
    Details
    Publication Date: 2022-12-12
    Description: How do recent changes in consumption in the wake of the COVID-19 pandemic affect the avoidance of packaging waste? How can an increase in packaging waste be countered and the previous trend towards unpackaged and reusable solutions be revived and promoted? To tackle these questions, we use a systemic approach that regards packaging as a network of interrelated interests of industry (manufacturing and logistics), trade (retail and catering), consumers and the waste management sector. To analyse this network, we applied three methods. First, we analysed secondary sources such as surveys. Second, we conducted semi-structured interviews with seven actors from industry, consumer education and waste management in May and June 2020. Third, we used the questions from the interview guideline to do an online survey among representatives of the public waste management industry.

    GLS Bank Carbon Footprint & Handprint : Projektbericht im Auftrag der GLS Gemeinschaftsbank eG (2021)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-02-18
    Description: Die GLS Bank finanziert gezielt nachhaltige Projekte und Unternehmen in den Bereichen erneuerbare Energien, nachhaltige Wirtschaft, Ernährung, Wohnen, Bildung & Kultur, Soziales & Gesundheit. Eine zentrale Herausforderung ist es, die Nachhaltigkeitswirkung der Finanz- und Anlagestrategie robust zu quantifizieren und transparent darzustellen. Die GLS Bank hat sich zum Ziel gesetzt, die hierfür notwendigen Methoden und Daten zur Bewertung der Nachhaltigkeitswirkungen ihres Finanz- und Anlagenportfolios schrittweise weiterzuentwickeln, um eine richtungssichere Portfoliosteuerung und Kundenbetreuung zu unterstützen. Ziel des Projektes ist zunächst, das Emissionsgeschehen der finanzierten Wertschöpfungskette abzubilden (Scope 3), aber auch die eingesparten Emissionen als einen Beitrag zum Klimaschutz zu bewerten (Scope 4). Es werden die Scope 3 Emissionen der GLS Bank in den folgenden Finanz- und Anlagebereichen für das Berichtsjahr 2019 bilanziert: 1. Aktien- und Klimafonds; 2. Kredite; 3. Unternehmensbeteiligung. Scope 4 Emissionen werden in Form vermiedener Emissionen (Carbon Handprint) dabei ausschließlich für Bereiche bilanziert, in denen THG-Reduktionspotentiale richtungssicher abgeschätzt werden können. Im vorliegenden Bericht wird der Untersuchungsrahmen, die vom Wuppertal Institut entwickelte Methodik sowie Lösungsstrategien für die Überbrückung geringer Datenqualität/-verfügbarkeit beschrieben. Die Robustheit der Ergebnisse wird durch Prüfungsmethoden reflektiert und dem Leser somit eine Interpretationsunterstützung gegeben. In einem Ausblick werden Weiterentwicklungsbedarfe und -möglichkeiten skizziert, um schrittweise eine zunehmend robuste und wissenschaftliche fundierte Methodik und Datengrundlage zur Bewertung der Klimawirkung sowie weiterer Nachhaltigkeitswirkungen des Finanz- und Anlageportfolios der GLS Bank in Zusammenarbeit mit relevanten Stakeholdern zu etablieren.

    Renewables Pull - Verlagerung industrieller Produktion aufgrund unterschiedlicher Kosten erneuerbarer Energien (2021)
    Details
    Publication Date: 2022-02-18
    Description: Damit sich die weltweit zunehmend ambitionierten Klimaschutzziele erreichen lassen, müssen auch im Industriesektor weitgehende Emissionsreduktionen innerhalb weniger Jahrzehnte realisiert werden. Expertinnen und Experten sind sich einig, dass dies nicht ohne den Umstieg von fossilen auf erneuerbare Energieträger und Rohmaterialien - sogenannte Feedstocks - umsetzbar ist. Im Zuge der verstärkten Nutzung dieser grünen Energieträger ist denkbar, dass sich deren Verfügbarkeit und Kosten zu immer wichtigeren Standortfaktoren für die Produktion industrieller Güter entwickeln werden. Dies könnte dazu führen, dass zukünftig Standorte mit kostengünstiger Verfügbarkeit von erneuerbaren Energien attraktiver gegenüber anderen Standorten werden und es dann zu Standortverlagerungen kommt - insbesondere im Bereich der energieintensiven Industrie. In dem vorliegenden Artikel greifen die Autoren diese möglichen Verlagerungen industrieller Produktion auf. In diesem Zusammenhang führen sie auch den Begriff "Renewables Pull" ein. Die in bestimmten Regionen der Welt kostengünstig und in großen Mengen verfügbaren erneuerbaren Energien könnten nach Ansicht der Autoren künftig eine Sogwirkung auslösen und bestimmte Teile der industriellen Produktion anziehen - auch Pull-Effekt genannt.

    Germany's transition to a circular economy : how to unlock the potential of cross-industry collaboration (2021)
    Berlin : Econsense
    Details
    Publication Date: 2022-02-18
    Description: The transition from today's "take, make, waste" economic paradigm to a circular economy requires a joint effort from actors on all levels: governments, business, and civil society. While companies are among the drivers of the circular transformation, they find it hard to achieve a circular economy on their own. Hence, cross-industry collaboration is one of the imperatives for scaling a circular economy. Against this background, econsense, together with Accenture and the Wuppertal Institute, launched its study "Germany's Transition to a Circular Economy - How to Unlock the Potential of Cross-Industry Collaboration". Based on a survey and expert interviews within the econsense community, the study finds that companies are yet to unlock the full potential of cross-industry collaboration. While two thirds of analysed industry collaborations have a high potential for scaling the circular economy, only 43 per cent of those already show a high degree of interaction. The study provides concrete guidance for companies to get started with circularity and identify the right partners for cross-industry collaboration. Specifically, the report recommends companies: 1) Understand what circularity is about and map it on their own operations and processes. 2) Understand the different circular business models and identify the ones relevant to each business. 3) Discover areas where collaboration can help to create the needed foundation and to execute circular actions.

    Eco-innovation and digitalisation : case studies, environmental and policy lessons from EU member states for the EU green deal and the circular economy : EIO biennial report 2020 (2021)
    Brussels : European Commission
    Details
    Publication Date: 2022-02-18
    Description: Digitalisation is taking place at a fast pace in all European countries and it is transforming the economies, societies, communication, jobs and the necessary skills for the workplace and everyday life. The Covid-19 pandemic is also accelerating digitalisation at many levels. To address the great challenges resulting from this, the European Commission has launched the Green Deal, a long-term transformation strategy towards an innovative and sustainable society. Three important initiatives under the Green Deal are the New Circular Economy Action Plan, the Biodiversity Strategy for 2030 and the Zero Pollution Action Plan. The various strategies and action plans draw up a large portfolio of measures, instruments and milestones that are always linked to digital technologies. Ideally, these are eco-innovative and sustainable and contribute to improving living conditions in Europe. The EIO Biennial Report 2020, which looks at a different topic every two years, considers digitalisation a major opportunity to accelerate the transition to a circular Europe. In the current report, the authors provide an overview of eco-innovation trends, illustrated by digital technology and policy practices that can further drive the circular economy.

    Kiel ist Vorreiterin : Zero-Waste-Strategien (2021)
    Details
    Publication Date: 2022-02-18
    Description: Auf dem Weg zu einer ressourceneffizienten Gesellschaft bedarf es richtiger Rahmenbedingungen, Informationen und Handlungsalternativen. Eine Möglichkeit, diese Voraussetzungen zu schaffen, ist ein kommunales Zero-Waste-Konzept. Zero Waste lässt sich übersetzen mit "Null Abfall, null Verschwendung" und verfolgt das Ziel, möglichst wenig Abfall zu produzieren sowie effizient und sparsam mit Ressourcen umzugehen. Ein solches Konzept wie in Kiel ist die Basis für eine Zertifizierung als Zero Waste City, eine Auszeichnung, die der europäische Verein Zero Waste Europe vergibt. 2007 wurde die italienische Gemeinde Capannori zur ersten Zero Waste City in Europa erklärt, seitdem sind knapp 400 europäische Gemeinden dieser Bewegung gefolgt.

    Nachhaltigkeitsfilter für öffentliche Mittel : Leitfaden zur Anwendung der EU-Taxonomie (2021)
    Berlin : WWF Deutschland
    Details
    Publication Date: 2022-02-18
    Description: Öffentliche Mittel für die Unterstützung von Unternehmen sollten bestenfalls so eingesetzt werden, dass sie eine möglichst große, nachhaltige Wirkung haben und mit einem gesellschaftlichen Nutzen verbunden sind. Das kann unmittelbar erfolgen, in dem die konkrete Förderung an bestimmte Vorgaben gebunden wird, wie etwa den Ausbau von zukunftsfähigen Infrastrukturen. Es besteht jedoch auch die Möglichkeit, die Risikoabsicherung von Unternehmen - beispielsweise über Bürgschaften oder andere geeignete Finanzierungskonditionen - an der Nachhaltigkeitsperformance der Unternehmen auszurichten. Der vorliegende vierstufige Leitfaden, den der WWF Deutschland und das Wuppertal Institut entwickelt haben, dient als Grundlage für die zielorientiertere Vergabe von Mitteln und deren praktische Umsetzung. Er baut auf der von der Europäischen Union entwickelten "Taxonomie" für nachhaltige Investitionen auf. Darin enthalten sind Grenzwerte, welche die Nachhaltigkeitsperformance wirtschaftlicher Aktivitäten definieren. Auf diese Weise lässt sich filtern, ob ein wirtschaftliches Vorhaben zukunftsfähig ist. Hierbei unterstützt der "Entscheidungsbaum" des Leitfadens die Anwendung der EU-Taxonomie als Regelwerk.

    Details
    Publication Date: 2022-02-18
    Description: Die Wirtschaftsförderung Region Stuttgart GmbH (WRS) unterstützt die Transformation der Region Stuttgart in Richtung Nachhaltigkeit und sieht die Bioökonomie als eine wichtige Strategie zu diesem Zweck. Die WRS hat das Wuppertal Institut mit dieser Kurzstudie mit dem Fokus auf die industrielle Bioökonomie beauftragt, um eine Informationsgrundlage für die Spezifikation weiterer Aktivitäten der WRS im Kontext der Bioökonomie zu schaffen. Die Studie gibt einen Überblick über definitorische Ansätze und Diskurslinien der Bioökonomie. Sie fasst Einschätzungen des deutschen Bioökonomierates zu Marktpotenzialen der Bioökonomie in verschiedenen Branchen zusammen, die u.a. für Automobil, Biotechnologie und IKT als gut eingeschätzt werden. Anschließend umreißt die Studie die Innovationsansätze Biomimikry und Biointelligenz. Für den Ansatz Biointelligenz zur biologischen Transformation der industriellen Wertschöpfung werden die in Studien von Dritten identifizierten Marktpotenziale der Biointelligenz zusammengefasst, u.a. in den Bereichen Unterstützungssysteme, Produktionssysteme/-technologien und Baumaterialien. Darüber hinaus stellt die Studie Schnittstellen relevanter Landesstrategien in Baden-Württemberg zu Bioökonomiethemen dar, die synergetisch genutzt werden könnten. Ergänzend gibt die Studie einen Überblick über die Akteurslandschaft in Baden-Württemberg. Der Überblick basiert insbesondere auf dem Bioökonomie Kompetenzatlas wissenschaftlicher Akteure, der von der Landeskoordinierungsstelle an der Universität Hohenheim herausgegeben wird, sowie einer Akteursanalyse aus dem Projekt "Bioökonomie in Baden-Württemberg", das am KIT durch das ITAS durchgeführt wurde und durch die BIOPRO Baden-Württemberg GmbH unterstützt wurde. Auf Basis dieser Informationssammlung entwirft die Studie weiterführende Fragen in Bezug auf mögliche weitere Aktivitäten der WRS im Kontext der Bioökonomie, u.a. die mögliche Nutzung von Innovationsansätzen aus dem Bereich der Living Lab und Reallaborforschung.

    Sustainable supply chains : global cooperative regional economies for prosperity and resilience (2021)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-02-23
    Description: Two thirds of today's world trade is based on global value chains and supply networks. Purely regional supply chains have become less important in recent decades. The effects of these globalised structures are manifold. On the one hand, they promote employment and generate prosperity. On the other hand, they are beset by extreme social, ecological and economic imbalances. The COVID-19 pandemic has demonstrated the fragility of existing supply chain systems. The lockdown continues to disrupt complex supply chains and many problems of existing production and consumption continue to worsen. COVID-19 is one example of the crises that can shake globally networked supply chains in the short term. Other crises, such as climate change, develop more insidiously and are less immediately recognisable. Different as they are, such crises have one thing in common: they highlight the vulnerability of global social and economic structures and illustrate the impact of global trade on the regions and people of the world. This is precisely where global sustainability strategy comes in - it aims to fundamentally reduce differences and inequalities in opportunities and quality of life. The COVID-19 pandemic has forced the entire world into upheaval, creating an opportunity to make sustainability a central political resilience strategy. In the wake of the Corona pandemic, the discussion about resilient communities has flared up. In order to guarantee supply in the face of such crises, these should be more strongly regional and circular in their economic approach and global and sustainable in their perspective. The aim should be sustainable, transparent, non-exploitative supply chains that guarantee the security of supply to cover basic needs and public services despite sudden changes and crises. This discussion paper draws a future scenario of globally cooperative, circular regional economies that fundamentally reduce global inequalities in opportunities and quality of life, while at the same time permanently preserving the natural foundations of life.

    Klimaneutralität in Unternehmen : zehn Empfehlungen für die Umsetzung (2021)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-11-10
    Description: Immer mehr Unternehmen verkünden, klimaneutral sein zu wollen und zahlreiche Firmen bieten bereits klimaneutrale Produkte oder Dienstleistungen an: Von der klimaneutralen Paketzustellung bis zur Flugreise. Doch was bedeuten die Neutralitätsziele der Unternehmen genau? Ist das gesetzte Ziel ambitioniert? Und welche Rolle spielt Offsetting, also der Ankauf von Klimaschutzzertifikaten und deren Anrechnung auf das eigene Klimaschutzziel? Die hinter den verkündeten Zielen stehenden Ansätze sind häufig nur schwer nachvollziehbar. Vor diesem Hintergrund gibt der vorliegende Zukunftsimpuls zehn Empfehlungen für die Festlegung und Umsetzung von Neutralitätszielen. Die Autorinnen und Autoren sprechen sich dabei unter anderem für die Nutzung einer robusten Datenbasis als Grundlage für Neutralitätsziele aus, betonen die Bedeutung einer transparenten Kommunikation und zeigen auf, welche Rolle Offsetting spielen sollte. So sollten angekaufte Klimaschutz-Zertifikate einen möglichst begrenzten Beitrag zur Zielerfüllung leisen und ausschließlich zum Ausgleich von Emissionen genutzt werden, die nicht reduziert oder vermieden werden können. Insgesamt sollten Neutralitätsziele nicht zum alleinigen Kriterium für ambitionierten Klimaschutz von Unternehmen gemacht werden, sie stellen vielmehr ein Baustein einer weitaus umfassenderen unternehmerischen Klimaschutzstrategie dar.

    Untapped: understanding the consumer in circular economy activities : empirical case studies on consumer behavior and motivation in the context of circular economy (2021)
    Details
    Publication Date: 2022-08-09
    Description: With increasing world population and an unsettling resource scarcity in the back, sustainble consumption has moved to the foreground of political, economical and social discussions. One major school-of-thought is Circular Economy (CE), an approach summarizing various sustainable consumption activites under one roof. However, quantitative studies on the consumer are rare, yet crucial for a transfer from linear to circular consumption. This dissertation adds to literature by providing pioneer insights into consumer behavior in CE as an overarching concept, instead limiting research on singular subconcepts. Namely, four consumer activities are studied: recycling, upcycling, renting and sharing. In order to identify relevant insights for both academics and practitioners in CE, the research question ("what drives participation in CE?") is broken down into sub-hypotheses, which are addressed by three empirical studies. Using the SOR-Model (adaption Belk 1975) as overarching logic, the three studies deal with (1) the consumer (and their motivation) and situational stimuli (both (2) offline and (3) online). Respectively, three data sets are consulted to assess the sub-hypotheses and to identify overarching insights on how to accelerate consumer participation in CE, The research methodology employed ranges from a structured equation model (SEM), a random allocation field experiment during Fashion Week in Berlin to a discrete-choice model with best-worst scaling. The dissertation succeeds in revealing that (1) different activities in CE can be summarized in one latent variable, proving CE as a wholesome concept in consumer-related activities; that (2) Trust has a leveraging effect on participation in CE activities. Further, Trust can be enhanced offline via face-to-face interaction and online via third-party online attributes.; and that (3) experience in CE activities affects perception of online attributes, implying the need for adapted measures when dealing with CE-unexperienced consumers as compared to consumers with prior experience in CE activities.

    The role of aggregators in facilitating industrial demand response : evidence from Germany (2020)
    Details
    Publication Date: 2022-03-07
    Description: Industrial demand response can play an important part in balancing the intermittent production from a growing share of renewable energies in electricity markets. This paper analyses the role of aggregators - intermediaries between participants and power markets - in facilitating industrial demand response. Based on the results from semi-structured interviews with German demand response aggregators, as well as a wider stakeholder online survey, we examine the role of aggregators in overcoming barriers to industrial demand response. We find that a central role for aggregators is to raise awareness for the potentials of demand response, as well as to support implementation by engaging key actors in industrial companies. Moreover, we develop a taxonomy that helps analyse how the different functional roles of aggregators create economic value. We find that there is considerable heterogeneity in the kind of services that aggregators offer, many of which do create significant economic value. However, some of the functional roles that aggregators currently fill may become obsolete once market barriers to demand response are reduced or knowledge on demand response becomes more diffused.

    Chemisches Kunststoffrecycling : Potenziale und Entwicklungsperspektiven ; ein Beitrag zur Defossilisierung der chemischen und kunststoffverarbeitenden Industrie in NRW (2020)
    Düsseldorf : IN4climate.NRW GmbH
    Details
    Publication Date: 2022-02-18
    Description: Mehr als sechs Millionen Tonnen Kunststoffabfälle fallen in Deutschland jährlich an, nur etwas weniger als die Hälfte kann werk- und rohstofflich genutzt werden, der Rest wird verbrannt. Gerade gemischte Kunststoffarten erschweren das Recycling. Hier bietet sich das chemische Recycling (Pyrolyse) an. Bei diesem Verfahren werden die Stoffe durch hohe Temperaturen zersetzt und in kleinere Moleküle aufgespalten. Diese lassen sich im Sinne der Kreislaufwirtschaft in neue Kunststoffe oder chemische Grundstoffe überführen. Die Schätzungen gehen von bis zu zwei Millionen Tonnen Kunststoffabfall jährlich aus, der auf diese Weise wiederverwendet werden könnte. Das vorliegende Diskussionspapier zeigt, dass Pyrolyse von gemischten Kunststoffabfällen die chemische Industrie sowie die Abfallwirtschaft klimafreundlicher gestalten kann. Im Papier geht das Autorenteam auf die Potenziale und Entwicklungsperspektiven für Nordrhein-Westfalen ein mit dem Ziel, wissenschaftliche Grundlagen für Investitionsentscheidungen und Projektentwicklung im Sinne der Kreislaufwirtschaft zu schaffen.

    Konzeption einer Wasserstoffmodellregion Emscher-Lippe : Ergebnisse des gleichnamigen Teilprojekts im Rahmen von "EnerAct - Energiewende und gesellschaftliche Megatrends. Konkrete Handlungsansätze" (2020)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-11-10
    Description: Die Emscher-Lippe Region ist seit vielen Jahren von einer intensiven wirtschaftlichen Transformation geprägt. Die fortschreitende De-Industrialisierung bzw. die Neuorientierung der Industrie nach dem Wegfall der Kohle- und Stahlindustrie stellt regionale Entscheidungsträger vor große Herausforderungen, wenn es darum geht, der hohen Arbeitslosenquote zu begegnen, Beschäftigungsquoten zu sichern, mit der prekären Finanzsituation in den kommunalen Haushalten umzugehen und den Wirtschaftsstandort zu stabilisieren und neu aufzustellen. Der Strukturwandel der Region ist mit Schließung der letzten Steinkohle-Zeche Ende 2018 nicht abgeschlossen, sondern geht mit dem Kohleausstieg im Energiesektor in eine zweite Phase. Dies sollte auch als Chance verstanden werden, den Wirtschaftsstandort Emscher-Lippe mit seinen energiereichen Industrien innovativ neu zu gestalten und die Region sowohl energetisch, als auch stofflich von der Nutzung fossiler Träger abzukoppeln. Eine wichtige Säule der regionalen Wirtschaftsförderung besteht darin, strategische Netzwerke und regionale Wertschöpfungsketten zu stärken, um die in der Region ansässigen (mittelständischen) Unternehmen zu unterstützen und den Strukturwandel innerhalb der dominierenden Industrien aus den Bereichen Energieerzeugung und chemischer Industrie zu begleiten. Die vorliegende Studie bereitet auf, welche Bedeutung die Wasserstoffwirtschaft in der Emscher-Lippe Region in diesem Zusammenhang derzeit spielt und zukünftig spielen könnte.

    Integrierte Klima-Industriepolitik als Kernstück des europäischen Green Deal (2020)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-11-09
    Description: Die Europäische Union (EU) hat erkannt, dass das Ziel der Klimaneutralität bis 2050 ein zentraler Innovations- und Wachstumsmotor für Industrie und Wirtschaft in der EU sein kann. Neben großen Chancen stellt dies die europäische Wirtschaft und überwiegend die besonders emissionsintensiven sowie im international starkem Wettbewerb stehenden Grundstoffindustrien auch vor erhebliche Herausforderungen. Eine integrierte Klima- und Industriestrategie ist für den Klimaschutz von zentraler Bedeutung, da auf die Produktion von Stahl, Zement, Grundstoffchemikalien, Glas, Papier und anderen Materialien in der EU und weltweit rund 20 Prozent der gesamten Treibhausgasemissionen entfallen. Auch in einer treibhausgasneutralen Zukunft kann auf diese Materialien nicht verzichten werden. Zugleich ist die emissionsfreie Herstellung der Materialien technologisch sowie mit Blick auf die dafür erforderlichen Infrastrukturen besonders herausfordernd. Dies gilt vor allem für die Frage woher die hohen benötigten Mengen an grüner Energie - insbesondere Strom und Wasserstoff - zu wettbewerbsfähigen Preisen kommen sollen. Analysen zeigen, dass trotz erheblicher Kosten bei der Prozessumstellung die Kosten der Transformation der Grundstoffindustrie für die Gesellschaft insgesamt tragbar sind. Denn bezogen auf die Endprodukte betragen die Mehrkosten meist nur wenige Prozentpunkte; die Preise von Rohstahl oder Zement dagegen würden sich zwischen einem Drittel und 100 Prozent verteuern. Da fast alle Grundstoffhersteller in starker Weltmarktkonkurrenz stehen, können sie die Investitionen in eine klimaneutrale Produktion und die benötigten Energieinfrastrukturen aber nicht ohne Unterstützung tragen. Das vorliegende Papier skizziert ein integriertes Klima-Industriepolitikpaket, das der EU ermöglichen kann, die bestehende technologische Führung in vielen dieser Industrien zielgerichtet zum Aufbau einer treibhausgasneutralen Grundstoffindustrie zu nutzen.

    Green accounting for a sustainable economy : policy use and analysis of environmental accounts in the Philippines (1999)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2018-11-21
    Description: Statisticians avoid getting involved in data analysis, leaving data users on their own in interpreting the results of their work. This is particularly unfortunate in a new area of applied statistics such as environmental accounting with which few are really familiar. Earlier this year data producers and users explored, in a national seminar, possible policy applications of the results of a "green accounting" project in the Philippines. The main findings of the author's contribution to the seminar, on which the present paper is based, are that environmental accounts: (1) present evidence of sustainable economic performance in the country during the relatively short-time period of 1988–1994; (2) provide information for environmental cost internalization; (3) may guide investment to environmentally sound production processes; (4) help to specify and monitor policies of natural wealth conservation, distribution and management; and (5) reveal major data gaps. The paper concludes that environmental accounts help to assess the sustainability of economic growth in terms of broadly defined capital maintenance. The sustainability of development, however, would have to be measured by alternative or supplementary physical indicators linked to quantifiable standards or targets.

    Notes: ---The composition and microstructure of syndiotactic para-methylstyrene/styrene copolymer was determined by a pyrolysis gas chromatography (Py-GC) method. This method uses the styrene and para-methylstyrene monomer peak intensities to determine the styrene and para-methylstyrene composition in the copolymer. The number average sequence length of styrene was calculated by using the triad peak intensities. Because of the low concentration of para-methylstyrene in the copolymer, the number average sequence length of para-methylstyrene was determined with formulas that incorporate the copolymer composition and the number average sequence length of styrene. The distribution of para-methylstyrene defined by the terms “percent of single units” and “percent of desired distribution” was calculated by the number average sequence of para-methylstyrene. This method has been tested with copolymers containing up to 24 mole% of para-methylstyrene. The composition results from Py-GC of para-methylstyrene and styrene copolymers used in this study were in excellent agreement with 1H-NMR results.

    Notes: ---A new ECD, the HP 6890 Series Micro-ECD, was designed to address inherent deficiencies in classical electron capture detectors (ECD), especially with respect to sensitivity, linearity, dynamic range, and ruggedness. Several novel technologies were incorporated in the totally new design and were refined through practical testing and user feedback. Validation of the micro-ECD performance was accomplished through side-by-side testing of the Micro-ECD with previous ECDs following US EPA Contract Laboratory Program methods for pesticides and PCBs. In addition, extensive interviews were conducted with early users of the Micro-ECD who also had experience with other designs running a variety of ECD methods. The design and resulting performance improvements are described.

    Notes: ---Data on the use of two chiral selectors, namely 18-crown-6 tetracarboxylic acid and a negatively charged cyclodextrin derivative (sulfated-β-cyclodextrin or carboxymethyl-β-cyclodextrin), in the same background electrolyte are presented. The use of such dual systems has a considerable influence on the resolution, as illustrated for the separation of tryptophan derivatives. Reduction of the consumption of chiral selector without significant loss in resolution was obtained by only partly filling the capillary and applying a run buffer without selector. This is illustrated for the chiral separation of tryptophan hydroxamate and the diastereomeric and enantiomeric separation of the dipeptide α/b-AspPhe-OMe.

    Topics: Chemistry and Pharmacology
    Notes: ---The three coffee diterpenes cafestol, kahweol, and 16-O-methylcafestol are mostly esterified with fatty acids. Little has been published about the diterpenes occurring in the free form. By means of gel permeation chromatography on Bio Beads S-X3, it is now possible to simultaneously analyze and quantify the small amounts of these compounds by RP-HPLC. In this way, free kahweol was first proved to be an ingredient of Robusta coffee. Various Arabica and Robusta coffees - both green and roasted - were investigated. Free diterpenes were found in green coffees in amounts below 200 mg/kg dry matter. In comparison to the respective total diterpene content determined by the same HPLC method after saponification of the coffee oil, the proportion of free diterpenes ranged from 0.7 to 3.5 %. During the roasting process, the three uncombined diterpenes behaved similarly: free 16-O-methylcafestol, cafestol as well as kahweol were degraded with increasing roasting temperature.

    Notes: ---In comprehensive two-dimensional gas chromatography (GC×GC), two capillary columns are connected in series through an interface known as a “thermal modulator”. This device transforms effluent from the first capillary column into a series of sharp injection-like chemical pulses suitable for high-speed chromatography on the second column. Dramatic increases in the resolving power, sensitivity, and speed of the gas chromatograph result. This paper describes the development of a robust and reliable thermal modulator for GC×GC.

    Topics: Chemistry and Pharmacology
    Notes: ---The effect of mobile phase modifier and additive on the chromatographic properties of various small polypeptides was explored under subcritical conditions. A polymeric column was used to separate various enkephalin analogs, bradykinin, and oxytocin using a carbon dioxide-based mobile phase with either an ethanol or a 2-methoxyethanol modifier. The role of the modifier was found to be secondary to that of the mobile phase additive. As progressively stronger acidic mobile phase additives were used, the peak profiles of the various polypeptides improved and retention decreased. Heptadecafluorooctanesulfonic acid was found to be the most useful additive for these types of solutes under near-critical conditions, while the potassium salt of heptadecafluorooctanesulfonic acid failed to elute any of the polypeptides. At low temperatures, pressure gradients with a carbon dioxide/ethanol/heptadecafluorooctanesulfonic acid ternary mobile phase produced reasonably good peak profiles with the polymeric column.

    Programmable Temperature Vaporizer (PTV) Applied to the Triglyceride Analysis of Milk Fat (1999)

    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: ---The PTV (Programmable Temperature Vaporizer) is a split/splitless injector which allows the sample to be introduced at a relatively low temperature, thus affording accurate and reproducible sampling. After injection the PTV is rapidly heated to transfer the vaporized components into the capillary column. This type of injector has proved to be an efficient tool for the evaluation of fatty acids, essential oils, and pesticides in food analysis. In this work the suitability of PTV for the analysis of milk fat purity by the Official EU method was evaluated. This method is based on the gas chromatographic determination of triglycerides only according to their total number of carbon atoms followed by the application of formulae deriving from multiple linear regressions. The analysis is currently carried out with a packed column or a short capillary column and an on-column injection system. Several samples of pure milk fat and mixtures of milk fat with foreign fat were analyzed with the same capillary column and by using both PTV and on-column injection systems. The results show that the gas chromatographic profile obtained by PTV is comparable with that obtained by the on-column injector, while repeatability and reproducibility data meet the requirements indicated in the Official Method. Therefore, this study demonstrates that it is possible to use the PTV instead of the on-column injector to determine the purity of milk fat with this method.

    Notes: Determination of the linear range is one of the main concerns in validation of an HPLC analysis method. It is particularly important since single point calibration will be then used routinely. We proposed an iterative methodology to handle this problem. The idea was, at each step, to test statistically whether the following point belonged to the same regression line. The methodology was then used to evaluate quantitatively the effect on linear range of a shift in detection wavelength or of the detector bandwidth. Although experimental results were globally in accordance with spectroscopic theory, magnitudes observed were rather large. So the linear range could vary by a factor of over 2 with changes in conditions that remained within the range of current practical values. Changes in detection wavelength were limited to about fifteen nm around λmax and the detector used was considered to be representative of modern high-performance UV detectors. The question of how to take consequences in method validation into account was raised. The solution proposed recommended that the validation was undertaken in conditions as close as possible to those where the method would be conducted routinely. This means with the same instrumentation and on the product of interest for analyses.

    Notes: ---The hyphenation of chromatographic separation techniques with NMR spectroscopy is one of the most powerful and time-saving methods for the separation and structural elucidation of unknown compounds and molecular compositions of mixtures. Most of the routinely used NMR flow-cells have detection volumes between 40-180 μL for conventional separations with analytical columns, and the newest designs employ detection volumes in the order of 200 nL for capillary separations. The low flow rates used in capillary chromatography permit the use of deuterated solvents. Unequivocal structural assignment of unknown chromatographic peaks is possible by two-dimensional stopped-flow capillary HPLC-NMR experiments.

    Topics: Chemistry and Pharmacology
    Notes: ---A commercial mixture of conjugated linoleic acid (CLA) isomers, reportedly consisting of six components, was recently resolved into 12 peaks attributed to CLA isomers using silver-ion high performance liquid chromatography (Ag+-HPLC). In this study, the coupling of two analytical silver-ion high performance liquid chromatography columns (tandem-column Ag+-HPLC) in series led to the enhanced resolution of CLA isomers. Many CLA isomers were baseline resolved and the pair 18 : 2 8,10 c/t and 18 : 2 7,9 c/t found in cheese products, was resolved for the first time. In this work, a similar commercial CLA mixture was separated into 16 peaks, while CLA isomers from cheese also gave rise to 16 peaks. As expected, the CLA isomers were separated into three geometric groups in the order trans,trans, cis/trans, and cis,cis. Semi-preparative Ag+-HPLC, followed by gas chromatography-mass spectroscopy of the dimethyloxazoline derivatives, was used to confirm the identity of the newly resolved positional CLA isomers. The double bond configuration of CLA isomers was established by gas chromatography-Fourier transform infrared spectroscopy. Two minor t,t CLA isomers found in cheese, presumably 18 : 2 t6t8 and 18 : 2 t13t15, were also separated. The CLA isomeric composition of 16 commercial cheese products was determined.

    Notes: ---Conventional operation of the GC Atomic Emission Detector (AED) system involves backflushing of the microwave induced plasma (MIP) during the elution of small volumes of solvent from the GC column. When performing multi-dimensional, on-line LC-GC-AED, significantly larger solvent volumes are introduced into the system and must subsequently be removed. Thus solvent venting procedures are required and the backflushing of the plasma must be extended to facilitate solvent but not solute removal. This study demonstrates the significance of memory effects imparted upon the MIP of the AED if solvent venting is incomplete. Comparison of conventional GC-AED and multi-dimensional LC-GC-AED is made with respect to a fossil fuel sample.

    Notes: ---The present paper describes the application of capillary electrophoresis in the micellar mode to the separation and quantitative determination of five phenylurea herbicides, viz. monuron, linuron, diuron, isoproturon, and monolinuron, in water samples. Using uncoated fused silica capillary and phosphate-borate buffer (pH 7.0) containing SDS, the five pesticides are resolved in less than 15 min and quantitatively determined by an ultraviolet detector at 244 nm. Method optimization and validation parameters are presented. Good linearity and repeatability were observed for all the compounds studied (correlation coefficients 0.999). The feasibility of the method developed was tested by simultaneous determination of these herbicides in environmental and drinking water samples at the minimum residue levels (MRLs) (0.1 μg/L) after solid-phase extraction (SPE) preconcentration procedure.

    Notes: ---A gas chromatographic method is presented for determining from 1 to 100 μg/mL of 1,4-dioxane in toluene with purities ranging from commercial to high-purity grades. This method relies on extracting 1,4-dioxane from toluene into water. The water extract is analyzed for 1,4-dioxane content by gas chromatography/flame ionization detection and a capillary column coated with a bonded polyethylene glycol stationary phase. Splitless injection is used to achieve a 1 μg/mL detection limit. Purging extracts with nitrogen after an initial analysis is suggested as an extract clean-up procedure and as a means to confirm the identification of 1,4-dioxane. However, for absolute identification of dioxane, gas chromatography/mass spectroscopy should be considered.

    Notes: When the column pressure drop is high, the average velocity of a carrier gas is proportional to the square root of the outlet velocity and the flow rate. Characteristic velocity, flow rate and pressure - the boundary conditions between low and high pressure drop regions - are introduced. Previously derived equations for average velocity vs. outlet velocity were modified to include the flow rate and to become more suitable for the separate studies of the low and high pressure drop regions.

    Notes: ---Normal phase liquid chromatography-gas chromatography was used with on-column interfacing and partially concurrent solvent evaporation in the analysis of process samples. Samples were taken from reaction mixtures, where the solvent was toluene. The analytes were oxygenated compounds: methyl isobutyrate, methyl methacrylate, methyl α-formyl isobutyrate, and methyl β-formyl isobutyrate. The analytes were transferred from LC to GC using back-flush with a solvent mixture of pentane and diethyl ether. Linearity, repeatability, and transfer efficiency were determined for the method. The method was applied in the determination of the analytes of two different process samples. The results were in good agreement with results obtained by the gas chromatographic method currently in use for the analysis of the process samples.

    Notes: ---The determination of the critical micelle concentration (CMC) of cationic surfactants by capillary electrophoresis was demonstrated. In this study, tetradecyltrimethylammonium bromide (TTAB) and dodecyltrimethylammonium bromide (DoTAB) were selected as cationic surfactants and propazine was chosen as test solute. In the evolution of the effective electrophoretic mobility of propazine as a function of surfactant concentration, a dramatic change in slope at a particular concentration is a good indication of the CMC of this surfactant. The CMC values determined experimentally were further confirmed by a curve-fitting approach. Simulation of the electrophoretic mobility curves as a function of surfactant concentration in both micellar electrokinetic chromatography and capillary zone electrophoresis using cationic surfactants as an electrolyte modifier was performed for propazine, and the intersection of these two mobility curves allowed us to precisely predict the CMC of the surfactant. The CMC values determined for TTAB and DoTAB are 1.6 ± 0.1 and 11.0 ± 0.1 mM, respectively, in the case of an electrolytic solution consisting of 70 mM phosphate buffer at pH 6.0. Moreover, the applicability of the electroosmotic mobility as a parameter for the determination of the CMC was examined.

Extraction of environmental pollutants from soil, additives from low density polyethylene, sulfa drugs from animal tissue, and drug from tablet was performed using both SFE and ESE. Results showed that a single instrumental system can be used to perform both ESE with organic solvents and SFE with carbon dioxide-based fluids. Each method has its own unique advantages and applications. The ability to carry out both solvent extraction and supercritical fluid extraction with one system has obvious economical advantages.
