Pyrolysis transforms problems into solutions

The transition from waste to new plastic takes place in reactors at WPU’s facilities.

The technology is based on pyrolysis that process the plastic at high temperatures.

The plastic oils can be used in the production of new plastic products or as environmentally friendly fuels. And as a result replace bio-oils cultivated on our agricultural land.

tonnes a day

Each reactor has the capacity to handle 17 tonnes of plastic waste daily.


The plastic waste is converted into 12 tonnes of plastic oils and 4.25 tonnes of biogas.


The facility handles virtually all types of plastic and leaves no environmental hazardous residues.

The process

About the process

Plastic can be recycled mechanically up to 6-7 times.

At this point, the building blocks in the plastic are so damaged that they need to be incinerated or deposited.

However, through pyrolysis WPU can now convert obsolete plastic into new products – and thereby bring new life to waste plastic.

We are not solving the plastic challenge alone

The technology behind WPU’s facility in Odsherred in Denmark is developed in cooperation with DTU.

In August 2020 WPU and DTU were granted a subsidy for the project by the Innovation Fund in Denmark. The project is led by DTU, and the subsidy has been used for research and technical development at DTU in Lyngby.
