A methodology to improve the recyclability rate of Strategic/Critical Metals from car electronics
Käsitlusala:
This document defines a method to support all the automotive actors in identifying the presence of SCMs in car electronics, particularly in ECUs, and disassembling/separating/recycling these components in a proper way. The final aim is improving the recyclability rate of SCMs from cars, create a market for secondary SCMs and reuse SCMs in new high-value applications.
The overall goal of the CEN Workshop is developing a CWA related to:
a) the identification of SCMs embedded ECUs (PCBs);
b) the information sharing among all the actors involved (for several reasons and with different roles) in automotive supply chains.
This document is intended to be used by car makers, car parts manufactures or suppliers and ELVs managers (e.g. car dismantlers and/or shredder companies which process ELVs). This document can support the policy makers in the development of a future digital product passport specific for PCBs and is based on the experience and results developed within TREASURE project. This activity is coherent with the new version of ELV regulation under development [7] and the current WEEE regulations [10].
Finally, the procedure could be adoptable by other sectors where the presence of electronics is relevant and SCMs can be recycled and reused.

Design-for-recycling guidelines for plastic construction products - Thermal insulation products of expanded polystyrene (EPS)

This document specifies the general “design for recycling” guidelines for EPS raw materials. It provides guidance on the impact of specific design characteristics on the recyclability of the product in practice and recommended design options to ensure that the product is recyclable, including target values and performance ranges, where applicable. It also provides a definition of recyclable product and of design for recycling.
This document refers to the recycling processes of EPS products. The sorting and collecting steps are not part of this document.
This document takes into account all currently known processes that are suitable to enable the circular economy for insulation materials. Particular attention is paid to ensuring that the most energy-efficient processes are given preference, especially mechanical recycling, unless reuse is already ruled out.
For some of these processes, practical experience has been gained over many years, so a basic knowledge base for the development of a guideline is already available.
At the same time, it is important to also take into account future-oriented processes, for which at the moment little but increasing experience is available or which have so far only been implemented on a small scale.

This document specifies a method for the photometric determination of dissolved chromium(VI) using
manual, e.g., hand photometry, or automated static, e.g., discrete analyser system, or automated
dynamic techniques, e.g., flow injection analysis (FIA), continuous flow analysis (CFA), or ion
chromatography with post-column derivatization (IC-PCR). Typical areas of application for the static
techniques as well as FIA and CFA are samples with Cr(VI) concentrations 2 μg/l in raw water,
drinking water, surface water, aqueous eluates, cooling water and treated wastewater, provided that
the Matrix does not contain any reducing substances. When using cuvettes with large optical path
lengths, e.g. >100 mm, the range of application can be extended to concentrations 2 μg/l Cr(VI). When
using coupled techniques (e.g. IC-PCR), Cr(VI) concentrations 0,02 μg/l can be determined.
The NP is based on DIN 38405-52:2020-11.
