Non-ferrous metals are about 6 percent of what goes through a shredder and bring in about 30 percent of the revenue. Sold as differentiated, furnace-ready products, their share rises to around 40 percent: roughly $180 per shredder input ton instead of $111.

In Training Session 2, Fred Cornell works through an example plant with 68 percent ferrous yield and 6.24 percent non-ferrous. He starts with what shredder residue contains. Metals make up about 22 percent of its weight, but only around 11 percent of its volume. Then he covers what the shredder itself can do to help the recovery plant. Denser shredded steel, with a target of about 100 lbs per cubic foot, improves liberation. A debulking step with an air-before-magnets layout can cut the volume the plant has to process by up to two thirds.

How do you measure the true performance of a non-ferrous recovery system? In this training session, we introduce the key metrics used to evaluate shredder efficiency: metal recovery efficiency and revenue recovery efficiency. 

You will learn how to quantify how much valuable metal is recovered from your feedstock, how to identify losses to waste, and how to assess the real financial performance of your operation. This session provides a structured methodology, including testing procedures and data analysis, to help operators better understand and optimize their recovery systems.

Our patented flotation process maximises the recovery of plastics from shredder residues.

The mix of rigid plastics is washed and placed in a flotation tank filled with a special medium. Unlike traditional processes that use salt, AD REM works with a pH-neutral substance that remains in suspension in the water. This means the medium can be fully recovered and reused, without corrosion or environmental impact.

The result: up to 70% of plastics previously destined for landfill are recovered, yielding separated fractions of chlorinated plastics, RDF plastics, PE/PP and PS/ABS.

Our patented flotation process maximises the recovery of metals from shredder residues.

The material, ASR, WEEE or IBA, is washed and placed in a flotation drum filled with a liquid of 1.4 kg per litre. Plastics float to the surface, metals sink. In a second step, we raise the density to 2.2 or 3.2 kg per litre to separate magnesium and aluminium from the heavy metals. The medium is recovered after each cycle.

The result: a separation efficiency of nearly 100%, yielding separated fractions of plastics, aluminium, magnesium and heavy metals — and a significant reduction in CO₂ emissions.
