What Is Plastic Pyrolysis How It Works Feedstock Outputs Plant & Equipment Feasibility Contact

Turn plastic waste into diesel, fuel and feedstock.

Plastic pyrolysis converts non-recyclable plastic waste into ASTM-spec diesel — replacing landfill with a revenue stream.

What plastic pyrolysis delivers

950 L
of diesel from a tonne of waste plastic
3–150
tonnes per day, in modular sizes
Cetane 57
vs 51–54 for conventional diesel
<50 ppm
sulphur — well under North American limits

Plastic pyrolysis heats plastic waste in an oxygen-free reactor and cracks it into a clean, fuel-grade diesel — a genuine alternative to landfill for the plastics no mechanical recycler will take.

The process, step by step

Shredded plastic waste Oxygen-free reactor heated 400–500 °C Catalytic converter cracks to fuel-grade Condensation vapour to liquid ASTM-spec diesel
1

Feed

Shredded plastic — unsorted, unwashed.

2

Heat

An oxygen-free reactor — breaks down without burning.

3

Convert

Catalytic cracking to fuel-grade chains.

4

Condense

Diesel, plus char and recoverable gas.

What you get out

ASTM-spec diesel

The primary product — drop-in fuel for engines, generators and boilers.

Recoverable gas

C4-and-below off-gas, fed back to power the process.

Carbon char

A solid residue, separated and handled safely.

Proven at commercial scale

Klean has delivered plastic pyrolysis projects in Canada, Germany and Malta — turning waste plastic into diesel and low-carbon marine-fuel feedstock. These are turn-key, commercial-scale plants.
