Metal recycling and metal shredding

The metal industry is a shining example of the circular economy. Old products are collected, crushed and melted down to be reused as a valuable raw material. The shredding of metals of all kinds, however, presents even industrial shredders with particularly great challenges. Metal waste is extremely abrasive, heavy and usually bulky. This includes, for example, production waste from the waste, automotive and electrical industries as well as the metal processing sector. Typical applications are punching waste, beverage cans, foils, profiles, milling and sawdust, light scrap, car body parts, wires, cables, sheet metal waste and aluminum scrap of all kinds.

Metal shredding as part of the recycling process

WEIMA not only shreds light metals such as aluminum and magnesium, but also copper, brass and bronze, as well as sawing and milling waste from steel. Before bulky materials can be further processed, they usually have to be shredded to a homogenous material size. Whether long profiles, cans and foils, or long and bulky chips and punching waste from production: our machines make everything small and reusable.


"Did you know that the recycling rate for aluminum beverage cans is over 99%? And we are actively contributing to it."

WEIMA shreds electrical waste

WEEE (Waste of Electrical and Electronic Equipment) is the fastest growing waste stream in Europe, growing three to five percent per year. In total, this amounts to around ten million tons of electronic waste, which corresponds to the weight of around 50,000 blue whales. However, less than a third of this waste is currently recycled professionally. The majority ends up in household waste or is exported illegally. This is a problem in many respects, since batteries in particular, but also other electrical appliances, can contain toxic pollutants. (Source: WEEE Europe)

Waste of Electrical and Electronic Equipment (WEEE)


According to the WEEE directive, electrical and electronic equipment can be divided into six categories:

1. Heat exchanger
2. Screens and monitors
3. Lamps
4. Large units from 50 cm
5. Small devices up to 50 cm
6. Small IT and telecom equipment

Shredding with WEIMA shredders is particularly suitable for transferring this electrical waste into the recycling cycle. Single-shaft or four-shaft shredders are available for this, depending on the application.



Shredding and briquetting of metal waste: Efficient duo

The shredding of metal waste represents the first step in the recycling cycle. The result is a homogeneous piece goods, which can now be further processed. However, loose material is only suitable for melting down to a limited extent, as a lot of burn-up occurs. The solution is briquetting. In addition to the further volume reduction, expensive coolants and lubricants, residual oils and emulsions can be recovered. Furthermore, the resale value of the raw material increases.
