Contaminant removal and sorting technology for household waste

Each year, German households produce around 38 million tonnes of waste. This gigantic mountain of rubbish harbours valuable raw materials that can be removed, recycled, processed and turned into new, high-quality products. Sesotec develops innovative sorting systems for sorting centres and recycling companies to divide mixed material flows into uniform fractions and eliminate contaminants.

Sesotec is a market leader in the field of contaminant removal and sorting technology. Our sorting systems reliably differentiate materials using various types of sensor technology and separate material flows with efficiency and precision.

Why is household waste recycled?

In 2016, each German produced an average of 462 kilogrammes of household waste, including residual, organic and bulky waste, paper and cardboard packaging, glass, wood, plastics, metals and much more. Only a small portion of waste still ends up in landfills. Most of the materials from household waste are sorted out, used as fuel or processed into secondary raw materials for creating new products. At modern sorting facilities, materials can be efficiently sorted out and sold at a profit. Doing so is not only eco-friendly, but also aids low-cost production of new goods.

How do Sesotec systems help you?

Sesotec has been developing innovative machines and systems for the recycling industry for more than 40 years. Our sorting systems cover applications for sorting household waste. They remove contaminants or metals and separate materials by colour, shape and type. In doing so, they play an important role in introducing reusable material profitably into the recycling loop.

Greater throughput levels, less loss of material and higher material purity increase added value. As a result, the purchase of equipment amortises rapidly. In addition, sorting systems help with sustainability, the conservation of resources and environmental protection, as less rubbish ends up in landfills or incinerators.

What products and materials are sorted?

  • Plastics, such as polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP) and polystyrene (PS)
  • Paper
  • Cardboard packaging
  • Beverage cartons (e.g. Tetra Pak)
  • Glass
  • Metal
  • Wood

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.

Mission PET – Circular economy needs material cleaning with state-of-the-art technologies

Mission PET sees the circular economy mission in the consistent implementation of PET recycling. The bandwidth for the use of recycled PET material is diverse. However, only high-purity rPET material also meets the requirements that correspond to those of virgin material. The demands placed on the recycling process for preparing the PET material are correspondingly high. Best decontamination and material cleaning of the PET starting material are the prerequisites for maximum purity of the end product.
