Pyrolysis transforms problems into solutions

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

The technology is based on pyrolysis which processes the plastic at high temperatures. Pyrolysis can be used to treat polymers that have exhausted their potential for mechanical recycling or otherwise cannot be recycled.

WPU has developed a batch technology and batch pyrolysis processes are far easier to construct and operate compared to other pyrolysis processes.

The pyrolysis facilities can process batches containing almost all kinds of plastic waste – homogeneous and nonhomogeneous. It creates a stable production and limits the resources needed for waste sorting before the pyrolysis process.

For the same reason, the technology used by WPU entails substantially lower costs than competing tech.

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.

17
tonnes a day

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

12
tonnes

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

0
residues

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 facilities is developed in cooperation with DTU (Technical University of Denmark).

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.
