Research on Remelting and Purification of Si-kerf for PV wafers is part of CABRISS, a European collaboration aimed to develop a circular economy mainly for the photovoltaic but also other industries such as electronics or metallurgy.

During production of silicon wafers out of silicon (Si) ingots and wafers, about 40–50% of the material is lost due to the cutting technique. The research had kerf from slurry based wafer cuttings undergoing several refining steps and being remelted into ingots for PV-application.

Conclusion: With 10%  refined material, ingots were still directionally solidified, whereas with 100% refined material, they were not. The presented refining method does not allow for ingots with 100% refined material to be used as PV-material.

The project Recycling of broken Si based structures and solar cells is part of CABRISS, a European collaboration aimed to develop a circular economy mainly for the photovoltaic (PV), but also for other industries such as electronics or metallurgy.

The paper presents some tests in which broken solar cell structures coming from an early stage in the PV production process chain as well as broken finished solar cells have been recycled into new silicon (Si) feedstock through demetallisation, purification and directional solidification.

The paper explores two different routes to remove diffusion layers and anti-reflection coating (ARC) on broken cells. It also presents the characteristics of ingots produced with the Si-feedstock from the two routes by directional solidification.

In a resource-constrained world the future economy will need to be circular.

From a policy perspective, the question is whether averting catastrophic environmental impacts through an accelerated transition to a global circular economy can also deliver sustained growth and jobs.

Multiregional input−output (MRIO) analysis models the interdependencies between industries and within/between countries as well as between intermediate and final goods producers and consumers, thus providing a useful toolbox for assessing social, environmental, and economy-wide impacts of the adoption of the circular economy.

This research paper resorts to this toolbox to compare the business-as-usual (BAU) scenario to an alternative circular economy scenario.

The EU is currently engaged in two transformations that could change our economy and society for the better: circular economy and digital transformation. If managed well, and in unison, they could help the EU address one of its greatest challenges: to build a sustainable, green economy that is competitive on the global stage.

The publication by the European Policy Centre (EPC) builds on the EPC Task Force on the Digital Roadmap for Circular Economy findings to make recommendations for the EU institutions for the next five years.

The TF explored the linkages between digitalisation and the circular economy, the opportunities created by data and digitally-enabled solutions, and the challenges associated with harnessing their full potential for the transition to a circular economy.

Packaging plastics can offer an almost infinite range of options for manufacturers, both in terms of function and design. Their durability and resistance to degradation means that if they ‘leak’ into the environment, they stay there. Leakage has been increasing rapidly and its detrimental impact, especially on the marine environment, has attracted wide public and political concern.

EASAC established in 2018 an Expert Group to look at scientific aspects of plastics packaging and the circular economy. This report is the result of an 18-month investigation and reviews the negative consequences of the current linear economy for plastic packaging, the scope for improvement towards a more circular pattern and options for increasing recycling rates and reducing leakage into the environment.

The 2020 Report on the Circular Economy in Italy, developed by CEN (Circular Economy Network) in collaboration with ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development) and Fondazione Sviluppo Sostenibile, analyses the state of play of the circular economy in Italy with, this year, a particular focus on the bioeconomy.

The report was presented during the 2^nd National Conference on the Circular Economy livestreamed on 19 March from Rome. It was introduced by Edo Ronchi, President of CEN, and Roberto Morabito, Director of the Department for Sustainability, ENEA, and President of the Italian Circular Economy Stakeholder Platform (ICESP).

This analysis by IEEP and SEI assesses to what extent the actions included in the new Circular Economy Action Plan published by the European Commission on 11 March 2020 may contribute to a more circular European economy within the boundaries of the planet.

The authors conclude that the action plan is a promising continuation of existing efforts, but ask for more concrete measures to address unsustainable resource consumption.

The authors make five recommendations to EU policymakers in this regard and emphasise the importance of EU Member States and the private sector showing leadership and willingness to innovate.

Europe is facing a growing mountain of used textiles. In North-West Europe 4700 kilotonnes of post-consumer textile waste are generated annually. Still, less than 1% of textiles produced are currently recycled into new ones, and around 50% are downcycled, incinerated or landfilled.

Automated sorting technologies could enable the industry to turn non-rewearable textiles into valuable feedstock for high-value recycling. Fibersort, a Near Infrared based technology, is able to categorise textiles according to their fibre composition, structure and colour.

At the end of each chapter of the report, recommendations are formulated for recyclers, manufacturers and brands to address the socio-cultural, physical and economic barriers for uptake of sorted textiles.

The report provides an overview of different organisations and an analysis of the local performances of 135 waste collection systems across Europe. It highlights the diversity of collection systems, with many different sorting systems and combination of collection modes (door-to-door, bring bank, combined, etc.).

This report is a publication of the ACR+ Waste Observatory whose objective is to allow consistent comparisons among local and regional authorities, in order to provide benchmarks on municipal waste management and identify effective waste strategies for quality recycling. The analysed data has been collected in the framework of the H2020 COLLECTORS project, aimed at identifying good practices to improve the quantity of sorted municipal waste leading to high quality recycling.

"Chambers for a Circular Economy - Actions to Support SMEs' Transition to a Circular Economy" aims to offer a clear overview of the wide range of initiatives led or co-managed by Chambers in the field of the Circular Economy, with the intention not only to inform and share innovative actions, but also to spur and motivate synergies, triggering collaborations and the creation of new business models. The aim of each and every of these projects is to enable businesses to evolve from a linear to a circular mode of production and consumption.

This publication presents a total of 32 projects initiated or co-led by Chambers in 13 countries, and categorized under 5 main topics:

• certification,
• circular skills,
• cooperation,
• reuse & recycle and
• waste prevention.
