The circular economy (CE) is gaining momentum in cities. To ensure a sustainable CE, it is crucial to measure the environmental performance of CE strategies. However, environmental assessments overlook several strategies that are a key feature of urban CE practice. These include reuse and repair, sustainable built infrastructure and urban land use, green public procurement, smart information and access technology.
To provide insights into the environmental performance and potential of these strategies, industrial ecologists and municipalities should:
collaborate with urban systems experts
quantify the environmental impacts of entire urban systems
combine environmental assessments with social and economic feasibility ones.
Many political, business and civil society stakeholders are disappointed with the German Packaging Act. They feel it makes a comparatively small contribution to the circular economy. This study explains why they are disappointed:
Policy-making became entangled in disputes between proponents of a private and a public system for waste collection. Stakeholder fears of potential radical changes led to a stalemate
Fears allowed only incremental changes in the Packaging Act
The incremental changes could not resolve existing conflicts.
Based on its findings, the paper proposes possible courses of action. To create a shift to a circular economy, dialogue is needed using methods which explicitly address fears and overcome the current stalemate.
This white paper on Quick Scan Circular Business Models - Inspiration for organising value retention in loops from the Dutch Ministry of Economic Affairs and Climate Policy offers an approach for developing a circular business model. It is based on a classification for existing and future circular business models developed in 2021. It consists of seven basic models geared primarily to the manufacturing industry, although it can also be used in other sectors.
The paper is divided into three parts:
an introduction explaining the background and central concepts
an overview of the seven circular business models comprising the classification, and
the actual Quick Scan.
The interactive Quick Scan version can be found here.
The article Implementation of circular economy approaches in the electrical and electronic equipment (EEE) sector: Barriers, enablers and policy insights by Vasileios Rizos and Julie Bryhn aims to enrich the research in the field of circular economy business models by focusing on the EEE sector.
The study adopts a multi-case study approach and uses a sample of 31 cases developed through the EU-funded CIRC4Life project and the snowball sampling method.
The findings show that despite the various policy instruments in place to boost the CE transition in this sector, gaps exist which require policy attention.
The study suggests actions to facilitate CE practices including knowledge sharing platforms and business partnerships as well as R&D project grants.
How can a "strategic stock management" approach shed light on the potential of circular strategies for critical raw materials? This reports provides insights at regional macro-economic level for policy-makers.
The future economic and environmental potential of a Flemish Circularity Hub for li-ion batteries from electric vehicles is explored as a case study with high policy relevance.
To evaluate the impact of adopting circular economy principles in cities – in terms of emissions, quality of life and resilience – Enel and ARUP, with the scientific support of the Enel Foundation, have collaborated on a research project focusing on four cities: Bogotá, Genoa, Glasgow and Milan, all committed to enhancing the energy transition.
The study concerns three key urban sectors:
mobility
built environment
energy systems.
It entailed interviews with stakeholders and analyses of existing decarbonisation policies and circular strategies. A reference model was used to help identify the most significant circular actions that could lead to a reduction in GHG emissions in three sectors.
The results could be used as a guide for decision makers.
The authors of the study apply ascendency analysis (a systematic method based on information theory for quantifying the efficiency and resilience of natural ecosystems) at EU level and discuss the implications for urban waste management systems, taking the Netherlands as an example.
They argue that ecological principles can be useful for developing human-made systems. The system is made sufficiently robust to be able to cope with shocks by including a diverse set of stakeholders who provide:
resource-use efficiency through specialised know-how in capturing, processing and delivering a range of resources, and
resilience by generating multiple paths that allow these vital resources to circulate throughout the urban network at different levels and rates.
Ascendency analysis is a systematic method grounded on information theory for quantifying the efficiency and resilience of natural ecosystems. We apply the method on an EU level and discuss the implications for urban waste management systems by taking the case of the Netherlands as an example. In line with other authors we argue that ecological principles can be useful for develop human-made systems. Robustness against shocks is then endowed to the system by including a diverse set of stakeholders who provide a) resource-use efficiency through a cache of specialized know-how in capturing, processing, and delivering a plurality of resources, and b) resilience by generating multiple paths that allow these vital resources to circulate throughout the urban network at different scales and rates
Ascendency analysis is a systematic method grounded on information theory which has been developed by ecosystem ecologists for assessing the sustainability of natural ecosystems. Here, we apply ascendency analysis to quantify the robustness of material and energy flow networks of the EU27. In line with other authors, we argue that ecological principles can be useful for developing robust circular human-made systems.
