"Circular economy (CE) is gaining popularity at different levels with the promise of creating more sustainable processes. In this context, cities are implementing a number of initiatives that aim to turn them into sustainable circular systems. Whether these initiatives achieve their sustainability goals, however, is largely unknown. Nevertheless, as the application of CE strategies is actively encouraged by many policies across the globe, there is a need to quantify the environmental impacts and to identify the strategies that support urban sustainability. This paper analyses the extent to...

"Circular City Governance - An explorative research study into current barriers and governance practices in circular city transitions across Europe presents the results of an empirical research study carried out by a team of the Nijmegen School of Management, Radboud University Nijmegen (The Netherlands), commissioned by the EIB. The research activities ran from October to December 2017. The main objective of the study was to support the EIB and other members of the UAPCE involved in the working group on “Circular City Governance” (CCG) with the identification, analysis and elaboration of...

This study aims to answer three main research tasks:

- Identify key succes factors as wel as issues hindering the development of industrial symbiosis
- Assess policy actions that support industrial symbiosis at different levels
- Assess the feasibility and options of EU-level interventions to contribute to scaling up and promoting IS initiatives across Europe or an EU-level trading platform for secondary raw materials (p. 10)

"Circular Flanders is the hub and the inspiration for the Flemish circular economy. It is a partnership of governments, companies, civil society, and the knowledge community that will take action together. These organisations are the core of our partnership. Each one has committed to carrying out a specific action." (https://circulareconomy.europa.eu/platform/sites/default/files/kick-off_...)

"The London circular economy route map outlines a vision of a capital city thriving through the adoption of the principles of circular economy: an economy which keeps products, components and materials at their highest use and value at all times."

"This report is presented in two parts: The first is the summary report of the Government Chief Scientific Adviser. This was developed as a result of seminars and the advice of the experts who provided the source of the evidence. The second part, the evidence, has been gathered from and written by a distinguished group of experts. The evidence takes two forms: chapters that consider a major aspect of the waste and resource productivity landscape; and individual case studies that illuminate points of detail and principle. The evidence section provides the views of the experts themselves,...

"Recycled concrete aggregates from demolition constitute one of the largest waste streams within the developed countries. These study aims to quantify environmental impacts associated with mixing compositions of concrete made of waste materials by using LCA. Environmental performances of natural, recycled and mixed 20-mm concrete samples, formulated with the same mechanical strength regarding the functional unit, were evaluated. Eight millimeter concrete samples, formulated with natural or recycled (concrete or terracotta brick) aggregates - with the same volume composition of the granular...

"This paper outlines some of the challenges cities are facing in today’s linear economy, explores the alternative of a ‘circular city’, and collates our research to date on the benefits of a circular economy for cities. Finally, it outlines outstanding questions on the topic, suggesting possible avenues of research for the future. 

In the coming decades, cities will be increasingly important as even greater rates of urbanisation are expected, and significant infrastructure investments and developments will be made. Cities could be uniquely positioned to drive a global transition...

This report wants to provide countries and their policy makers who are interested in a transition to the circular economy with a toolkit. To test this toolkit, a case study was performed for Denmark. It focused on opportunities in several sectors; food and beverage, construction and real estate, machinery, plastic packaging and hospitals. Eight important conclusions were drawn:

• The transition to a circular economy can deliver the expected lasting benefits of a more innovative, resilient and productive economy.
• The circular economy provides many opportunities that are...

"The ROMEO project tackles process intensification for catalytic-driven and eco-friendly reaction systems. ROMEO stands for "Reactor Optimisation by Membrane Enhanced Operation". It is a Research and Innovation project and has received funding from the European Union's Horizon 2020 research and innovation programme. ROMEO focuses on a new reactor concept to drasti-cally reduce energy consumption. It will lead to the manufacturing of bulk chemicals at consider-ably lower operational and investment costs. The aim of ROMEO is to reduce energy consump-tion by up to 80% and emissions by up to...
