Opis:
In an attempt to reduce waste originating from end-of-life vehicles (ELVs) which is becoming a serious environmental problem, the European Union enforced in 2000 the End-of-Life Vehicles Directive 2000/53/EC. Each European member state has to comply with the achievement of the following recycling and recovery targets: 80% and 85% by 2006 and increasing to 85% and 95%, respectively, by 2015. The required and achieved recovery and recycling targets for ELVs in Poland in 2011 have been discussed and compared. The data shows that the achieved targets of recovery and recycling were about 82% and 80%, respectively. Therefore, the barrier factors affecting management of ELVs have been identified and the route useful to comply ELVs recovery and recycling in Poland and for other developing countries has been presented. The experience shows that this goal could be achieved by energy recovery and materials recycling of automotive shredder residue.

Opis:
Waste of Electrical and Electronic Equipments (WEEE) is one of the fastest growing waste streams in the world. The treatment of WEEE with high content of precious metals (Au in particular) has received the most attention due to their high economic potential. The development of simple, environmentally friendly and cost-effective methods for the recovery of metals from “low-value” WEEE (e.g., <100 g/t Au) is important from the circular economy perspective. In this study, the separation of base (Cu) and precious (Ag) metals from scrap TV boards (STVBs) by using a zig-zag air separator was investigated. Size-reduced scrap STVBs (-1 mm) were subjected to separation tests after the removal of the fine fraction (-0.1 mm). The sized scrap material (-1 +0.1 mm) was determined to have a metal content of 15.4% Cu, 47 g/t Ag and 0.05% Fe, with no gold. In the air separation tests, the effect of air flow rate (4-16 m/s) on the recovery of metals was studied. Increasing the air flow rate resulted in low metal recoveries with concurrent high metal grades in the concentrate. Separation efficiency (%) calculations showed that the most efficient separation is obtained at the highest air flow rate of 16 m/s. At this flow rate, 15.4% of the material was recovered in the concentrate which contains 62.3% Cu and 198 g/t Ag with recoveries of 63.3% Cu and 73.9% Ag. The findings indicated that zig-zag air separators can be used to obtain a metal-rich fraction under suitable conditions of the flow regime.
