Plastcon – Plastic waste conversion
Recycling again and again
Our Plastcon system is based on a technology known as pyrolysis – a process in which a material, in our case, plastic, is exposed to high temperatures in an oxygen-free environment. With the plastic pyrolysis technology in Plastcon, it is possible to thermally recycle plastic waste from both industry and households – and, importantly, to do so with an absolute minimum of pre-treatment. This technology allows the plastic waste to be recycled again and again.
Below, you can gain insight on the Plastcon process, and follow the plastic waste's journey step-by-step into a becoming a useful resource once again through.
1. Unwashed, presorted plastic waste
Plastcon can process and convert various types of plastic waste from both industry and households - and no pretreatment is needed using pyrolysis in chemical recycling.
2. Shredder
The shredder cuts the untreated plastic waste, including unsorted materials like organic waste and metals, into small pieces.
3. Sorting
The plastic feedstock, now in small pieces, goes through sorting mechanisms, including two NIR-scanners (near-infrared), removing pollution like glass, sand, stone, metal and organic materials.
4. Densifier
The plastic fragments are heated up to 200°C (392°F) and melted into a coherent mass. This decreases the volume with 60-80%.
5. Pyrolysis
The reactor vaporises the mass at 400-700°C (752-1292°F) in an oxygen-free environment - the pyrolysis process is the core of our technology.
6. Codensation
The first end product is now ready: carbon black. About 10% of the plastic waste has been turned into carbon black that can be used to colour new plastic materials.
7a. Pyro gas
The first end product is now ready: gas. About 15% of the plastic waste has been turned into gas that can be used to produce power or heat.
7b. Pyro oil
The processed plastic waste is turned into pyrolysis oil. This can be used for new, high-quality plastic products, such as food packaging and medical equipment.
8. New plastic for the consumer
The third end product is now ready: pyrolysis oil. About 75% of the plastic waste has been turned into pyrolysis oil. This can be used to produce new plastic materials.
