Addressing climate change and establishing a circular economy are some of the top priorities of our time. These projects present manufactures, processors, and recyclers of plastics with a variety of challenges, but also offer numerous opportunities. The global approach to plastic must be rethought – from legislation, to the development of new packaging materials, to innovative recycling technologies and use concepts.
Recycling saves energy, and used plastics are
often cheaper than virgin material. Furthermore, each ton of recycled plastic used in place of comparable
virgin material saves between 1.45 and 3.22 tons of greenhouse gases. However, recycling
used plastics is only a profitable venture if the material has previously been
separated into homogeneous fractions by color and type in order to live up to
high quality standards. Our sorting systems are there to handle the job – sorting PET, HDPE, PE, and PVC 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.
Material analysis systems
from Sesotec are used in quality laboratories to inspect outgoing goods.
Previously, material analysis had to be carried out in a time-consuming, manual
process. In just a few minutes, Sesotec analysis systems generate consistently
high-quality and reproducible reports on the composition of plastic types and
color errors.
Recycling converts used plastic products into recyclate. This recyclate
can be processed in place of virgin material to create new plastic products,
which themselves can be recycled again after use. Foreign object detectors and
material analysis systems from Sesotec help make this cycle more efficient and
profitable.
Recycling 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.
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.
Which building blocks are necessary for a closed-loop plastic circular economy and which important parameters there are to close the loop, we will go into in the second part of the
"Circular Economy"
article series.
Reiling is prepared to fulfill this need, offering an entire range of services from collection (full service or DIY), to processing (converting bottles to flakes), to creating carefully controlled end products. For those who will eventually buy the flakes, color and material purity are of central importance, as high-quality starting materials are needed to manufacture new products.
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.
