In 2012, there were around 2,150 thermal waste treatment plants operating globally with a total annual waste treatment capacity of almost 250 million tons. And that number continues to grow.
Incinerated municipal solids and other waste streams results in a significant amount of ash residue, which often contains valuable metals. The amount of this remnant being created globally is rapidly increasing due to legislation which prohibits landfilling and creates new incentives for incineration. TOMRA Sorting sensor-based systems allow waste management businesses to capitalize on today’s challenges whilst simultaneously enabling them to look to the future with confidence.
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.
Now in its fourth generation, the FINDER specializes in effectively separating high purity metal fractions from even the most difficult fractions in terms of composition, grain size and mix from mixed waste and metal streams.
Cutting edge X-ray sensors empower the X-TRACT for special sorting tasks.
