Sorting and contaminant removal for metal recycling

Scrap metal can be melted down any number of times and turned into new products without a loss in quality. Our systems separate metals from the material flows and sort them into homogeneous fractions by type to ensure efficient and eco-friendly recycling.

Why is metal recycled?

In Germany, 25.6 million tonnes of scrap is melted down in blast furnaces each year. The recycled material accounts for more than half of the national steel production. However, steel is certainly not the only metal that is recycled. Scrap iron, lead, zinc, aluminium and copper are also used to produce new metalware. Metals can be melted down any number of times and turned into something new. While quality levels go down for many other materials during the recycling process, scrap metal consistently yields high-quality products, which makes metal the ideal material for recycling. Due to global shortages of raw materials, the importance of recycling them is growing rapidly. By recycling metals, it is possible to conserve resources, save up to 95 per cent of the energy required for manufacturing them and significantly reduce production costs.

How do Sesotec systems help you?

In order to use scrap metal to produce new materials, the different types of metal first have to be sorted and separated into homogeneous metal fractions. Sesotec sorting systems remove metals from shredder fractions or separate different types of metal from one another.

To differentiate between metals more securely, various types of sensor technology are used:

  • Inductive sensors
  • Optical sensors
  • Laser and X-ray technology


What products and materials are sorted?

Our systems

  • sort all types of metal from mixed materials
  • recover ultra-pure metal fractions, such as stainless steel or aluminium
  • sort visually distinguishable types of metal, such as copper or zinc
  • sort based on the chemical composition of metal alloys, such as cast aluminium or wrought aluminium alloys.

White Paper

The circular economy: Challenges and opportunities for Recyclers and plastics processors

The plastics industry is under pressure. Between climate change, excessive consumption of finite resources, and vast amounts of plastic waste in the world’s oceans, plastics are coming to be seen in a different light by politicians, businesses, and consumers alike. Read in our e-book about the most important factors of a functioning circular economy, especially which challenges and opportunities exist for recyclers and plastics processors.

RE-Glass helps Hungary‘s glass recycling industry get fit for the future

Foreign materials posed the biggest challenge to the new plant. Contaminants such as ceramics, stones, porcelain (CSP), metals, paper, and plastics comprise as much as 15 to 20% of the total weight of all collected glass waste. To overcome this challenge, KRS supplied a sorting system that meets these requirements.
