More and more plastics processors are turning towards recycling. Not only does this save energy, but used plastics are often cheaper than their new counterparts as well. However, recycling used plastics is only a profitable venture if the material has previously been separated into homogeneous fractions by colour and type in order to live up to high quality standards. Our sorting systems are there to handle this job – with precision, reliability and efficiency.
Sesotec is one of the leading specialists for industrial plastics-sorting machines and systems. Our systems reliably differentiate materials using various types of sensor technology and efficiently separate material flows into homogeneous fractions by colour and type.
Recycling saves energy, is good for the environment and is economical too, as recycled materials are frequently cheaper than new ones. What is more, it helps businesses that process plastics become more independent from fossil feedstock and cushion rising costs of raw materials. Recycled plastics can serve as an equal substitute for new, crude-oil-based materials in many applications. In addition, they can be recycled in many ways. For example, PET bottles can be turned into PET bottles (bottle-to-bottle principle) or textile fibres, polystyrene can be turned into pens, and CDs can transform into computer casing.
Plastics collected for recycling must have a high degree of purity. Only then can they be economically recycled and introduced as high-quality materials back into the production cycle. However, sorting certain plastics can place complex demands on the sorting system. Our separation and sorting systems remove contaminants, such as metals, wood or extraneous plastics, from the material and separate mixed material flows into homogeneous fractions by colour and type. To ensure safe detection, the systems are equipped with near-infrared sensors and high-resolution CCD cameras, for example.

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 plastics-recycling companies in particular and cover the entire range of contaminant removal and sorting. This extends from a sorting system designed to handle larger objects, such as PET bottles, to the intricate sorting of plastic regrind and PET flakes.
Our sorting systems work with precision, speed and efficiency. Better material quality, greater throughput levels and less loss of material increase added value. As a result, the purchase of equipment amortises rapidly. The machines can also reliably handle complex sorting tasks. They are used to pre-sort materials, perform quality checks, as well as sort or separate the following:
All Sesotec systems have a modular design. Depending on the application, the components that are necessary for a specific sorting task can be combined in one machine.
