Chemical Recycling

An efficient way to recycle waste plastic

Chemical recycling can increase plastics recycling rate and give new, high-quality life cycles to this valuable material. For plastics, it is a true circular solution.

Chemical Recycling can increase the amount of recycled waste plastic and enable circular lifecycles as it can turn plastic waste into new quality products.

The value of waste plastic

Waste plastic may be worth a lot. Probably so much that you can build a sound business around your waste plastic. And who doesn’t want to earn money and be circular with its waste at the same time?

Clenflex has test facilities to conduct pyrolysis tests of your waste. Our tests will show how much oil your waste plastic will produce. It will also show the quality of the oil and if it meets the expectations of international oil companies. If it does, your waste plastic may be worth a lot.

The solution to improve the waste plastic quality

The old saying “Garbage in – Garbage out” also works when it comes to the pyrolysis process. The quality of the generated oil entirely depends on the quality of the plastic which is fed into the system. We always start our projects to gain a deep insight into the waste plastic which we have to convert. Based on this we design a robust and modulated pre-treatment system that will feed our pyrolysis reactors.

from waste to value

The Pyrolysis process

End-of-Life Plastic is no longer just waste. Processes like pyrolysis are these days gradually turning waste plastic into a commodity.

The output Oil can be refined into new chemicals and subsequent new plastic. The output Gas is recycled into heat and electricity. The output Char is used in concrete and asphalt.

A lot of other materials are very suitable for chemical recycling. Clenflex is very far with a new process to recycle glass fiber from old windmill blades.

our services

We have several offerings

Flexible solutions

Based of a 5 tons/day reactor we sell a flexible and mobile plant which can be located exactly where there is a need to clean up for smaller amount of plastic waste.

Stationary Plants

Based on several 25 tons/day reactors in parallel we have investment opportunities in complete turnkey pyrolysis plants. These plants will be sized to regional need for waste plastic recycling.

Pyrolysis tests

Together with our vendors we are able to offer pyrolysis tests of your waste plastic. The price for the tests vary according to amount of tests materials and the use of external consultants.


We offer to do consulting services in connections with tasks and projects that focus on utilizing pyrolysis. We can co-partner in projects we together explore new solutions based on pyrolysis.
