WEEE management in Europe and China - A comparison.

Over the last years Europe and China have developed specific regulations to address the challenge of managing Waste Electrical and Electronic Equipment (WEEE). Households in today's urban China are similarly equipped with electrical and electronic appliances as households in European metropolitan areas, which in turn will lead to similar per capita generation rates in WEEE. While the challenge is a similar one, the systems, technologies and legislation in place in Europe and China are partly different, partly aligned to each other. In Europe WEEE collection is based on existing municipal structures. Additionally, retail and other take-back channels are in place. In China the informal sector dominates WEEE collection, being more competitive and flexible and offering pecuniary reimbursement to consumers. In Europe manual dismantling as a first treatment step has been gradually replaced by mechanical break up of appliances, followed by sorting out of hazardous and valuable components. In the subsequent second treatment level, cathode ray tubes are separated, whereby compound materials like motors and coils are mechanically treated, printed circuit boards go to special smelters, and plastics are separated and partly recycled. In China large formal dismantling capacities have been set up in recent years. There dismantling practices follow similar principles as in European plants; however, further processing is only partly implemented in Chinese recycling facilities. Specifically metallurgical treatment of printed circuit boards is still not existent in China. Companies selling electrical and electronic products within the EU are obliged to organise collection and treatment. This has led to a larger number of producer responsibility organisations. Financed and controlled by producers and importers, these systems aim to fulfil legal requirements at optimised costs subject to compliance with environmental standards and monitoring requirements. The Chinese system is built on a state controlled fund which subsidies formal recyclers. For these recyclers this financial support is essential to compete with informal recyclers, who operate at lower costs and do not necessarily comply with environmental standards.

Modelling informally collected quantities of bulky waste and reusable items in Austria.

Disparities in earnings between Western and Eastern European countries are the reason for a well-established informal sector actively involved in collection and transboundary shipment activities from Austria to Hungary. The preferred objects are reusable items and wastes within the categories bulky waste, WEEE and metals, intended to be sold on flea markets. Despite leading to a loss of recyclable resources for Austrian waste management, these informal activities may contribute to the extension of the lifetime of certain goods when they are reused in Hungary; nevertheless they are discussed rather controversially. The aim of this paper is to provide objective data on the quantities informally collected and transhipped. The unique activities of informal collectors required the development and implementation of a new set of methodologies. The concept of triangulation was used to verify results obtained by field visits, interviews and a traffic counting campaign. Both approaches lead to an estimation of approx. 100,000 t per year of reusable items informally collected in Austria. This means that in addition to the approx. 72 kg/cap/yr formally collected bulky waste, bulky waste wood, household scrap (excluding packaging) and WEEE, up to a further 12 kg/cap/yr might, in the case that informal collection is abandoned, end up as waste or in the second-hand sector.
