Plaxx

Plaxx®

Plaxx is our registered trademark for the hydrocarbon product produced from End-of-Life Plastic waste. Plaxx can be graded according to customer requirements ranging from light oils to solid waxes.


Technical parameters

Plaxx specifications*

Our patented process combines thermal cracking with intelligent process control, producing a spectrum of products that are classified into three distinct groups.

Plaxx-8 is a highly paraffinic Naphtha equivalent product suitable for polymer manufacturers as feedstock to develop virgin plastics.

Plaxx-16 is a range of ultra clean and low Sulphur fuel oils. They are available in multiple grades for both marine and industrial applications. They are compliant with the 2020 MARPOL1 Sulphur fuel limits and MCPD2 industrial combustion limits.

Plaxx-40 is our range of highly paraffinic slack waxes available in three different grades.
