The informal sector is described as groups of persons who act in parallel to official waste management systems without official authorisation. Such informal activities can result in risks as well as benefits both to the environment and involved stakeholders, which explains the continuing lively discussions in politics, science and society.
Transhipments of waste electrical and electronic equipment (WEEE) are increasingly focused in Germany. In addition to informal exports via the port of Hamburg to countries such as China, Ghana or Nigeria, informal transports to Eastern European countries have been recognised for decades. This paper describes investigations regarding the characteristics, transhipped amounts as well as the eco-efficiency of informal sector activities originating from Eastern European countries, while thereby highlighting transhipments of used appliances to destination countries and a corresponding sale for reuse.
Investigations reveal that a majority of informal collectors originate from Poland, Czech Republic, Hungary and Romania and are recognised across Germany. A high WEEE specialisation was determined, whereby average annual transhipped amounts are estimated at 77,000 tons. Collected materials are transhipped and partially sold for reuse. A case study considers the example of Polish informal collectors. The ratio between economic and environmental performance reveal that informal sector reuse activities in Poland achieve a higher environmentally sound performance in comparison to further usage of appliances under consideration. The informal collection of a television in Germany (and subsequent reuse in Poland) causes 8.34 kg less specific CO2 emissions per spend-costs (€) than the production, usage and further use in Poland. Conversely, a further use of a television in Germany only results in 2.2 kg less CO2 emissions per spend-costs (€).
These results demonstrate that reuse as a result of informal sector activities can have a positive effect. Future electrical and electronic products available for reuse will have lower energy consumptions. A positive contribution to resource protection is thereby achieved while extending already short life cycles. Taking into account a dependency on collections with respect to their income, a pure ban of informal sector activities would therefore be socially counterproductive. A structured and controlled accomplishment of informal collection processes would open up new opportunities to enlarge the (already existing) concept of reuse at an international level.
