In this paper three approaches on transitions pathways are combined to study the role of agricultural nature conservation in the Dutch land use domain for achieving internationally agreed climate and biodiversity targets. The three perspectives used are the Multilevel Perspective (MLP), Initiative Based Learning (IBL) and Integrated Assessment Modelling (IAM). The analysis provides insights in how the combination of different research approaches can lead to more comprehensive policy advice on how agricultural nature conservation could help to achieve internationally agreed sustainability goals related to climate change and biodiversity. IAM shows under which conditions agricultural nature conservation could be consistent with European and global long-term goals regarding food security, biodiversity and climate. MLP provides insight into the extent in which agricultural nature conservation has affected or changed the existing nature and agricultural regimes. IBL, finally, reveals the challenges of encouraging agricultural nature conservation with policy measures. Our analysis shows that a combined perspective provides a deeper understanding of the underlying processes, reasons and motives of agricultural nature conservation, leading to more comprehensive policy recommendations.
Artificial intelligence in the sorting of municipal waste as an enabler of the circular economy
(2021)
The recently finalized research project "ZRR for municipal waste" aimed at testing and evaluating the automation of municipal waste sorting plants by supplementing or replacing manual sorting, with sorting by a robot with artificial intelligence (ZRR). The objectives were to increase the current recycling rates and the purity of the recovered materials; to collect additional materials from the current rejected flows; and to improve the working conditions of the workers, who could then concentrate on, among other things, the maintenance of the robots. Based on the empirical results of the project, this paper presents the main results of the training and operation of the robotic sorting system based on artificial intelligence, which, to our knowledge, is the first attempt at an application for the separation of bulky municipal solid waste (MSW) and an installation in a full-scale waste treatment plant. The key questions for the research project included (a) the design of test protocols to assess the quality of the sorting process and (b) the evaluation of the performance quality in the first six months of the training of the underlying artificial intelligence and its database.
A policy mix for resource efficiency in the EU : key instruments, challenges and research needs
(2019)
Against the background of an often wasteful use of natural resources, the European Union has made resource efficiency a top policy priority. Policy formulation is, however, at a very early stage in many Member States, with often vague notions of what resource efficiency means, characterised by fragmented instruments and overlapping competencies. This paper develops a conceptual framework for defining, assessing and developing resource efficiency policy mixes. It argues that a mix of policies and instruments is best suited to overcoming the complex challenges of the 21st Century. Such a mix addresses multiple resource domains at a strategic, high level and contains interacting instruments targeting multiple actors, levels of governance and sectors and life-cycle stages of resource use. This paper looks at criteria for effective resource efficiency policy instruments, presents both an indicative policy mix across 9 policy domains and case studies (on environmental harmful subsidies, supply chain efficiency in food systems and product-service systems) and identifies key challenges to overcome trade-offs in instrument design, maximise synergies, reduce conflicts, promote coherence, coordinate activities and move from theory to practice. Research needs are discussed regarding who shall devise, implement, and coordinate such a policy mix, considering negotiating power, timing and complexity.
Treating waste as a resource and the design of a circular economy have been identified as key approaches for resource efficiency. Despite ambitious targets, policies and instruments that would enable a transition from a conventional waste management to an integrated and comprehensive resource management are still missing. Moreover, this will require innovative policy mixes which do not only address different end-of-pipe approaches but integrate various resource efficiency aspects from product design to patterns of production and consumption. Based on the results of a project funded by the Seventh Framework Programme for Research and Technological Development named "POLFREE - Policy Options for a resource efficient economy", this paper addresses several aspects of the conceptualization of policy mixes with regard to waste as a specific resource efficiency challenge. The guiding research interest of this paper is the combination of policies necessary to create a full circular economy. In a first step, the present waste policy frameworks, institutions and existing incentives at national level are examined in order to disclose regulatory and policy gaps. Based on this, the second part of the paper describes and analyses specific waste-related resource efficiency instruments with regard to their potential impacts under the constraints of various barriers. Based on the assessment of the country analyses and the innovative instruments, the paper draws conclusions on waste policy mixes and political needs.
Bisher ist die vollständige Schließung von Stoffkreisläufen durch die Verwendung von Abfällen als Ressource in Deutschland nur eine Vision. Der Beitrag führt das Konzept der Kreislaufwirtschaft ein und konkretisiert es am Beispiel der Reparatur und Wiederverwendung von Produkten. Anschließend werden Hemmnisse betrachtet, die es auf dem Weg zur Kreislaufwirtschaft zu überwinden gilt und mögliche Lösungsansätze beschrieben.
Reuse is still seen as a "niche phenomenon" and consumers seem to waste economic opportunities linked to buying and selling second-hand products. For this reason, this paper focuses on incentives and barriers to sell and buy second-hand products, as indicated in the literature, and applies a theoretical framework of transaction costs to explain the existing consumption patterns. For this paper, a representative online survey was conducted in which 1023 consumers in Germany participated, age 16 and older. The data were analyzed for statistically significant deviations between different groups of economic actors selling or buying second-hand products. Results show that valuable unused products exist in households, but barriers such as uncertainties about the reliability of the buyer or the quality of the product hinder the transition into sustainable consumption. Different forms of transaction costs are important explanatory variables to explain why consumers nevertheless predominantly buy new products, although they are aware that second-hand would save money and make an individual contribution to climate protection.
Facing an ever-increasing global consumption of natural resources and related environmental as well as socioeconomic challenges, the transition towards a circular economy will be of crucial importance. The issue is high on the political agenda, especially since the European Commission published its Circular Economy Action Plan in December 2015. Apparently different stakeholders have very different perceptions of the concept as well as different expectations for its implementation. During a workshop series by the Friedrich Ebert Stiftung, experts from policy, science, administration, industry and unions discussed key issues for the circular economy: What's the status quo in Germany? How can the circular economy be implemented in a comprehensive and efficient way? Which instruments are available? Is the legal framework on EU and national level sufficient for the evolvement of a circular economy? What is the role of the consumer? What are the economic potentials especially with regard to job creation? How can research and innovation policy contribute to this process? This paper aims to summarise the different discussions.
Die nachhaltigkeitsorientierte Transformation von urbanen Räumen ist eine akute Herausforderung. In den letzten Jahren haben koproduktive, experimentelle, transdisziplinäre und häufig informelle Stadtwandelprojekte als Such- und Lösungsräume hohe Sichtbarkeit erlangt. Schlüsselakteure hierfür stellen - so die These - Verwaltungsvertreter:innen einer integrierten Stadtentwicklung und -planung, Wissenschaftler:innen einer transformativen Forschung sowie zivilgesellschaftliche Stadtmacher:innen dar. Die Autor:innen, verankert in diesen drei Gruppen, kritisieren die häufig nur situative Zusammenarbeit dieser drei Akteursgruppen. Ein Modell der Zusammenarbeit im Spannungsfeld zwischen Gemeinsamkeiten, jeweiligen Potentialen und herausfordernden Eigenlogiken der Akteurssysteme wird entwickelt. Darauf aufbauend wird vorgestellt, wie durch strategischen Trialog und reflexive Lernprozesse die Zusammenarbeit verbessert und die Wirksamkeit koproduktiven und experimentellen Stadtwandels erhöht werden kann.
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.
Businesses like Airbnb have shown that a successful circular economy (CE) business can operate exclusively online. Although online communication and web appearance attributes have been subject to academic research given accelerated digitization, there is still a lack of knowledge about online attributes and their role in facilitating CE. We close the portrayed knowledge gap by conducting a discrete-choice experiment with best to worst scaling and focusing on the effect of CE experience on the perception of a CE website by ranking nine online attributes, grouped in three subsets. We therefore contribute by identifying online attributes that are perceived as favorable for CE businesses and detect how participation in CE activities affects the perception of these attributes. We find that third-party associated online attributes (e.g., user reviews or third-party guarantees) rank significantly higher throughout CE consumption patterns of the sample, being always amongst the top three attributes. This novel finding on online preferences opens a new direction for further research, as well as allows practitioners to optimize online operations accordingly. Furthermore, we find that users without prior touchpoints with CE have a higher need for information about the business model as compared to CE active users who are more interested in community related attributes.
