Many countries will have to consider incineration in order to manage their waste, due to a lack of space and a desire to achieve internationally recognized environmental targets. High metal content that exists within the resulting ash residue represents a commercial and environmental opportunity for waste management businesses.
The recovery of ferrous and non-ferrous metals from ashes is a very important part of an incinerator’s recycling footprint. It has traditionally been efficiently achieved by using magnets which recover over 90% of the metals. The non-ferrous metals traditionally have been recovered by Eddy Current Separators. However, this technology does not perform as well and recovery rates for the non-ferrous metals are only 40% at maximum. Introducing TOMRA Sensor equipment to an existing process immediately minimizes metals losses and maximizes revenue.
