Magnetic recovery at EFW plants

EFW plants in the UK handle more than 2 million tonnes of domestic waste each year. According to Government statistics, about 4.2% of this waste is steel packaging which could be recovered for recycling.

However, with conventional techniques, the average ferrous content of magnetically recovered material is lower than the 85% level required by the steel plant. Therefore, the quality of this material needs to be upgraded.

New technology raises economic and environmental efficiency

New trommel technology can significantly increase the ferrous yield of the process, creating a product which is suitable for high quality steelmaking operations. For new EFW plants, the ideal solution is to ensure that trommelling technology is included along with magnetic extraction technology in the initial plans for the plant. The cost of this investment is recouped typically within a year and from then on generates income.

How we can help

We can help by:

• Identifying magnetic extraction opportunities in new and existing waste management operations by indicating likely benefits and costs. Operators are encouraged to consult with Corus Steel Packaging Recycling for advice at the design stage of the incineration process.
