Purity matters – in the recycling industry

Many materials can be recycled to create new, high-quality products. However, the purity of the material is crucial to efficient recycling. Our separation and sorting systems remove contaminants and separate mixed material flows into homogeneous, unmixed fractions. By doing so, they facilitate a high degree of material quality and profitable recycling.

Our resources are limited, so the importance of recycling continues to grow. Nearly one in two trading and consumer goods companies depend on the availability of raw materials and sees recycling as a way to achieve greater sustainability. Recycled materials are turned into new products that can be manufactured in a cost-effective, resource-friendly and eco-friendly manner.

What benefits do sorting systems provide?

Higher material quality and greater added value: In order to recycle glass or metal economically, the recyclable material which is collected must have a high degree of purity. Our separation and sorting systems precisely remove contaminants and separate material flows into homogeneous, unmixed fractions. Recycling rates of up to 100 per cent are possible with our systems for applications that involve recycling used glass and some plastics.


The benefits of using our sorting systems?

  • They remove impurities and contaminants with precision
  • They work continuously at a constant speed (in contrast to sorting by hand)
  • Their operation is user-friendly (plug-and-play principle)
  • They function reliably and are easy to maintain
  • They are designed to handle high capacity levels and have a long useful life
  • They have a modular design and can therefore be adjusted to handle different sorting tasks
  • They can be integrated into existing recycling facilities
  • They boast low levels of wear and energy consumption
  • They have a low total cost of ownership
  • They amortise rapidly
  • They ensure a high quality of secondary raw materials
  • They protect processing machines, prevent breakdowns and increase process continuity and productivity

What materials are sorted?

Our systems sort the following materials, among others:

  • Plastics: polyethylene terephthalate (PET), high-density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC), engineering plastics, mixed plastics and bioplastics
  • Glass: flat and container glass, special glass types (e.g. heat-resistant glass, leaded glass, display glass, solar panels, etc.)
  • Scrap: automotive scrap, scrap metal, electrical/electronic waste
  • Other materials: household waste, wood


What can we do for you?

Sesotec has been one of the market leaders in the field of contaminant removal and sorting technology for more than 40 years. We develop standard solutions as well as complete custom solutions for recycling companies. Sesotec covers the entire range of contaminant removal and sorting from material flows, which extends from a sorting system designed to handle larger objects to one that focuses on the delicate task of removing small particles. Through innovative sensors, such as high-resolution cameras, metal detectors and smart software solutions, we help you to manufacture products in top quality with maximum output and to avoid wasting resources. Our machines boast the highest degree of detection accuracy, function reliably over many years and are easy to operate, clean and maintain.

Sesotec is partner of Blue Competence

As an internationally operating company in the fields of product inspection and recycling technology, we see it as our social responsibility to commit ourselves to the careful use of resources and environmental protection.

This is why we are a partner in the Blue Competence sustainability initiative (www.bluecompetence.net).

Blue Competence is an initiative of the VDMA (www.vdma.org) to promote sustainability in mechanical and plant engineering, but also to make sustainable solutions known to the industry. With our partnership, we commit ourselves to adhering to the 12 sustainability principles of mechanical and plant engineering (www.bluecompetence.net/about).
