Prior to incineration, a good deal of waste is already separated and various types of metal are recovered. Yet there’s always a range and quantity of metals that cannot be recovered even by the best manual pre-sorting from the residual waste.
Together with its partner Heros, AVR is ensuring that all these metals from the supplied residual waste are effectively reused. An intensive and extremely fine-meshed process that is performed with sieves and magnets. Even the tiny ball of a discarded ballpoint pen finds a new use again. This is the most hygienic and environmentally-friendly form of recycling for disposed-of tin cans.
2 kg of metal are still recovered from every 100 kg of residual waste: that´s 7% of the bottom ash. AVR works together with several partners in order to recover metals by filtering flue gas residues as well. This flue gas cleaning makes it possible to capture very small metal particles:
- Metals from bottom ash (7% of the bottom ash in total): 5% ferrous (lead, iron, scrap) and 2% valuable non-ferrous (aluminium, zinc, brass, silver and gold)
- Metals from flue gas purification: the intensive cleaning of flue gases traps small metal particles. In the residues of this process one thus finds various metals that can be recovered. This method is still in the experimental phase. AVR is working on a number of inventive projects: metal from fly ash Nyrstar, Antimony, Bromide, ...
The applications these metals can be used in are legion: for manufacturing wire, as a protective coating for cars, as a zinc layer in rain pipes or even in baby ointment. Moreover, chances are good that your mobile phone contains a rare metal that was recovered from waste . . .
