Final Conference, May 13 th 2015
A project funded by the
European
Union

Primary resources
Electronics production industry
Secondary materials production waste
WEEE
Recycling facilities
Informal collection formal collection
Large generators
Households
2

• Linking supply and demand of secondary raw materials in electronic production and recycling (chain approach).
• The development of an adequate recycling
infrastructure for WEEE as post-consumer waste and secondary raw materials from electronic producing industry.
• The development of a knowledge structure on Design for Recycling between the recyclers and the electronic producing industry

WASTE
TRACKING
SYSTEM research
Waste tracking systems in EU member states
Waste list training implementation
Waste tracking system in CN
(e-WTS)
Train-the-trainer on e-WTS e-WTS online
Regional training courses on e-WTS
Recyclers in e-WTS
6

• Based on an analysis of waste tracking systems in Europe a system (e-WTS) was developed
• Through a web portal recyclers provide information on input and output material streams for monitoring
• Tested and implemented
• Training for recyclers and local authorities
Training toolkits on e-WTS, Guidelines

Material Flow Analysis is a systematic assessment of the flows and stocks of materials
(goods and substances) within a system defined in space and time. It connects the sources, the pathways and the intermediate and final sinks of a material. If substances are considered we can also call it Substance Flow Analysis.

Existing collection schemes for WEEE in China
• Collection from large generators (public institutions) is regulated by the National
Regulation on State-Owned Assets
Management
• Collection from other sources (households, business) today is dominated by the informal sector
17

• Formal collection
– Initiated as pilots (through retailers and collection companies, OfN, 2009-11)
– Collection service by recyclers (individual cases)
– Internet applications to support collection
– Specific case: collection scheme for mobile phones
(market driven, for remanufacturing, resale)

Collection costs are only a part of the overall costs:
- Collection and logistics
- Treatment
- Office, communication, overhead 21

23

Large appliances, e.g. washing machines
In Europe
• removal of hazardous component by dismantling (capacitor, Hg component)
• mechanical processing by shredder & separation technologies
In China
• Manual dismantling
24

Cooling & freezing, e.g. refrigerators, AC
In Europe
• dedicated installations to remove CFCs from the cooling circle
• Removal from insulation (encapsulated cutting mill, underpressure), followed by mechanical processing
In China
• Same technology
25

Small WEEE, e.g. PCs
In Europe dismantling or mechanical break-up and sorting for hazardous components and valuable materials
• mechanical processing
• Specific processing of PCB (!)
In China
Manual dismantling, only partly processing of PCBs
26

Screens, ie. CRT
In Europe
• dismantling
• specific treatment to separate glass
• Mechanical processing
In China
Manual dismantling, glass separation, partly further processing (plastics, PCBs)
27

State of the art in WEEE recycling
28

• e-WTS as a monitoring tool established and in use
Secondary Materials Exchange Platform (SMEP) to link supply and demand of secondary raw materials developed
• Analysis of collection systems for WEEE: WEEE from large generators regulated, WEEE from households mainly collected through informal sector
• Recycling: considerable amounts recycled in the designated recycling facilities, 1 st level treatment similar to European
• Training toolkit and Best practice examples for the use of secondary materials and Design for Recycling developed
