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.

EASAC Report - Packaging plastics in the 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.

This retrospective report is a review of the plans set out by Circular Flanders in the Kick-off Statement.

The most important finding? A good deal more was accomplished than initially anticipated. For example, the opportunity to launch three Open Calls, permitting the funding of over 130 innovative circular economy projects. The Green Deal on Circular Construction was also an unprecedented opportunity, as was the complementary reinforcement of the OVAM team of experts in ecodesign and area-specific operations, allowing the scope to expand.

Sustainable construction guidelines for public authorities – A circular economy perspective aims to help public authorities navigate through the topic of sustainable construction, understand what it means and determine how to encourage it.

The guidelines are especially targeted at local and regional authorities, as they play a crucial role in the whole construction life cycle not only by stimulating innovation and cooperation between all actors but also because they work at a level close to citizens.

Unlike most of the literature on the topic, these guidelines focus on circularity and material resource efficiency, rather than covering only energy efficiency extensively. Moreover, the report goes beyond waste to integrate the whole value chain of the construction sector.

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.

Connecting local agricultural supply chains through insect farming

Up to 90 million tonnes of food are wasted every year in the EU, half of which is generated at production and/or processing stage.

Being highly versatile and efficient, insects can bio-transform many of these materials (before they become "waste") into a wide range of higher-value products and ingredients that can further be included into the food and feed chains. Their added value goes beyond that of an alternative feed ingredient.

The lower Feed Conversion Ratio (FCR) of insects confirms their efficacy, but also their ability to concentrate lower value materials into ingredients of superior quality, such as proteins and lipids, in line with the natural nutritional needs of aquaculture, poultry or swine.
