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.

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 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.

In the development of the circular economy, discussion around circular business models and circular revenue models is booming.

But what is a true circular business or circular revenue model? When can these models be applied, and what are the barriers that still exist?

For the past decade the authors of this paper have gathered practical experience with the implementation of circular revenue models such as lease, pay-per-use and take-back schemes. It is from this experience that they noticed that the current institutional economic framework hinders the transition to the circular economy.

The paper provides insight in four key barriers, providing a real-life business case as an example for each. It also includes a guideline for policy makers on how to address these barriers.
