XTL — Waste Oil to Liquid

Used lubricating and industrial oils become clean diesel — turning a hazardous disposal problem into a fuel asset.

Clean Diesel
The Challenge

Millions of Litres, Nowhere Good to Go

Mines, fleets, workshops and factories generate huge volumes of used oil — a hazardous waste that is costly to dispose of and damaging when dumped. XTL re-refines it into clean, usable diesel.

The Process

Waste Oil → Treatment → Clean Diesel

A dedicated upgrading train that handles the contaminants typical of used oils — metals, water, additives and oxidation products.

1
Collection & Pre-treatment

Waste oils are collected, dewatered and filtered — removing free water, solids and coarse contaminants.

2
Re-refining

Thermal and chemical treatment strips additives, metals and degraded compounds from the oil.

3
Upgrading to Diesel

Fractionation and finishing produce clean diesel meeting fuel specifications — ready for fleets and gensets.

Key Benefits

Why Waste Oil to Liquid

  • Hazardous waste diverted — used oil becomes fuel instead of a disposal liability
  • Disposal cost avoided — turn a cost center into a fuel supply
  • Circular economy — lubricants complete the loop back into energy
  • On-site potential — mines and large fleets can process their own waste oil
  • Drop-in diesel — for trucks, heavy equipment and generators
