Last September 7th – 9th the Electronic Goes Green 2016 Conference was held in Berlin. Electronics Goes Green is the world’s leading conference on electronics & environment that offers an opportunity to show results and innovative green solutions. The event also showcases the future trends and solutions towards sustainable development in the electronics sector.
Waste of electrical and electronic equipment (WEEE) contains a series many of valuable materials and substances and some of them are currently not recycled properly. The Fraunhofer IVV aims to close the loop for PC/ABS from housing polymers coming from WEEE. Martin Schlummer presented the current state of the work at the Conference Electronic Goes Green 2016 in Berlin. The results show that the solvent-based CreaSolv® Process can be applied to selectively dissolve PC/ABS from mixed WEEE plastics fractions. After separation of non-target materials pure PC/ABS is recovered from the polymer solution whereas the solvent is recycled within the process.
Fraunhofer IVV and partners in the CloseWEEE consortium held presentations in the event.

Recovery of PC/ABS from WEEE Plastic Shred by CreaSolv® Process
As of 2010 Eurostat reported that 3.3M tonnes of WEEE is collected in the EU annually. Many components of WEEE effective recycling technologies have already been developed and put into practice (e.g. copper, gold, polypropylene, polystyrene) there are significant valuable components which are not exploited yet.
These include PC/ABS, plastics used as standard casing material for modern consumer electronics. PC/ABS is currently collected with halogen-rich WEEE plastics and not recovered yet. The recovery of PC/ABS as a secondary polymeric raw material is highly challenging as even small shares of foreign materials cause significant negative effects on mechanical material properties.
Currently, the European CloseWEEE project investigates innovative sorting and recycling techniques capable of recovering highly pure PC/ABS.
This paper presents results indicating that pre-treatment of mixed shred of WEEE by x-ray transition (XRT) and density sorting enables an effective pre-concentration of the target polymer PC/ABS. XRT provides a fraction of halogen-free polymers, whereas subsequent sorting by a sink and float approach enriches PC/ABS further to a purity of 80%. The chain of purifying processes is finalised by the solvent-based Creasolv® process.
Recovery of Bromine and Antimony from WEEE Plastics
Current technologies for recycling plastics from WEEE aim at the major polymer types, i.e. ABS, PS and PP, which are free of brominated flame retardants (BFR), are separated from the mixed plastics stream by means of density separation and/or spectroscopic sorters and leave a fraction containing significant amounts of flame retarded ABS, PS.
As high industrial consumption faces limited supply and accessibility, antimony has been identified as a critical element in the EU and therefore is an interesting target element in urban mining approaches. Separation of fraction of concentrated BFR free of metals enables bromine recovery from those fractions in pyrolytic processes producing bromine for new and safe bromine-based flame retardants (like PolyFR).
The technological approach of the project bases on a dissolution based recycling concept (CreaSolv) that allows to selectively extract ABS and PS from the halogen fraction. At the current project stage, the technical feasibility of this approach has been demonstrated in laboratory scale. It has been upscaled recently to small technical scale using a decanter centrifuge. Results show, that application of centrifugal forces separates Sb2O3 to more than 90 % from the dissolved polymers whereas BFR stay in solution.
The CloseWEEE 4th General Assembly along with the Review Meeting was held between September 27th – September 29th in the facilities of the VHS Simmering in Vienna, Austria.
The General Assembly counted on the participation of the Project Officer, Marco Recchioni and the Project Technical Advisor, Margaret Bates from the University of Northampton.
At the end of the meeting, a tour of the facilities of The Disassembly and Recycling Center (DRZ) in Vienna was carried out. The DRZ, partner in the CloseWEEE project, is a recycling, ReUse and upcycling company for electrical devices. For more information about DRZ, visit: http://www.drz-wien.at/
CloseWEEE is conducting a survey that will help identify barriers and limitations of reusing recycled polymers (halogenated and non-halogenated), as well as limitations and constraints in the use of recovered additives in new applications which will determine the viability of cost efficient solutions in the Waste Electrical and Electronic Equipment (WEEE) market.
The questionnaires are short (less than 20 questions- 10 minutes), and as a participant you will:
– Receive the full report of the Market Research
– Subscribe to our Newsletter with relevant information about the WEEE market
– Participate in a prize draw to win a €500 Amazon Coupon*
– Include your company’s name on the list of supporters of this H2020 European project**
We have targeted five (5) different collectives. Please click on the one that better suits the nature of your company/organisation.
WEEE Managers: the authorised organisations in charge of the treatment of the WEEE streams after collection. WEEE managers can receive the WEEE streams from authorised collection facilities or from E&E producers.

Standardisation and Certification bodies:
Standardisation bodies are public or private organisations that propose, develop, establish, monitor and/or coordinate the voluntary standards.
Certification bodies are those organisations which audit and certify that material and products comply with relevant standards.
Policy makers and Public Bodies are in charge of the formulation, implementation and transposition of the legislation, regulation and directives and the effectiveness of these.

Vertech and Exergy on behalf of the CLOSEWEEE consortium are glad to present the project at the “NEW_INNONET PROJECT STAKEHOLDER CONFERENCE: TOWARDS NEARZERO WASTE AT EUROPEAN AND GLOBAL LEVEL” on June 8 and 9.
The NEW_InnoNet project is funded by the EU Programme Horizon 2020 as an initiative to establish a European platform for stakeholders, aiming to show how the concept of the circular economy can be enhanced and stimulated. In this interactive event, different actors, including companies, researchers and government organisations, will meet together and discuss about the future of the circular economy in Europe. Different lines will be covered during the conference: barriers for the European circular economy, plastics in the circular economy, Waste Electrical and Electronic Equipment (WEEE) and End of Life Vehicles (ELV) among others.

Dr. Erasmo Cadena and Mr. Antonio Barona, partners of the CloseWEEE project (from Vertech Group) and professors of the Université Nice Sophia Antipolis (UNS) in Nice (France), have presented and explained the project’s objectives and activities to 20 students of the Master 1 Energie, Matériaux et Environnement (EME) at the UNS.
During this event, students learnt about the CloseWEEE technologies and the possibilities of recovering polymers and additives as well as the creation of the Recycler Information Center (RIC), the recovery of critical metals and minerals from batteries, and other relevant activities undertaken during the project execution.
The 3rd General Assembly of the CloseWEEE project has successfully taken place at the facilities of Coolrec in Waalwijk, Netherlands. During this meeting, each Consortium Member introduced the updates and the next steps forward in their respectively led Work Packages. Two parallel sessions were also developed during the meeting with the aim to discuss the technical WPs as well as a brief pilot activity for the market activities.
During this meeting, a brief technical tour was also performed in the Coolrec recycling installations in Waalwijk
