Why metal ‘waste’ is so much more than scrap

Shredding metal waste

Smelting old scrap to produce new metal is one of the oldest ‘circular’ concepts there is, which goes some way to explaining why UK metals recycling is a £5.6bn industry. But ever-changing economic forces make this a volatile market for operators to trade in.

Why metal ‘waste’ is so much more than scrap

How can UNTHA help you shred metals?

Engineered for the toughest metal applications

Our comprehensive range of powerful, four shaft metal shredders provide a hard-wearing solution for even the toughest applications

Protection against unshreddables

Rugged reinforced frames give operational stability, double collar cutting disks deliver stronger cutting forces, and a slow speed, high torque drive increases resistance to unshreddables, for consistent, long-lasting machine performance.

Defined fraction size

With a number of configurable screen options, we’ve thought about particle homogeneity for optimum onward treatment.

Optimal metal recovery

We’ve developed a unique metal clean up system that has attracted the attention of operators worldwide, due to the 40% improvement in high quality recyclate recovery rates it can achieve. This can equate to thousands of pounds of additional revenue per month.

Metal waste shredding

Why shred metal?

Many recyclers and scrap merchants rely only on traditional, cumbersome shear equipment to cut metals down, because the perceived high-wear nature of metal shredding is deemed too cost prohibitive.
Reliance on this basic shear methodology means savvy alternative sorting, grading, separation and size-reduction processes are overlooked. Metal recyclate quality therefore remains low and revenue potential is limited.
Shredders help to liberate the valuable metals that would otherwise remain ‘locked’ in complex products such as uPVC windows, WEEE and end-of-life vehicles. Elsewhere, in MRFs or alternative fuel production plants, they rid metals of contaminants such as plastic film that would render the scrap worthless.
Integrate carefully-positioned magnets and other separation equipment and the volume of ferrous and non-ferrous scrap for resale, is higher still.
