Torrefaction mode

Bio-coal and torrefied biomass from continuous torrefaction

In torrefaction mode, our patented reactor roasts biomass gently without oxygen. It drives off moisture and light volatiles and leaves a dark, brittle fuel that handles and burns like coal.

What torrefaction does

Torrefaction heats biomass to roughly 250–300 °C with very little oxygen. Compared with raw biomass or white pellets, the torrefied product:

  • holds more energy per tonne
  • repels water, so it can be stored outdoors and transported like coal
  • grinds easily, so it can be fed alongside coal in existing mills and burners
  • does not rot or degrade in storage

What it makes

Bio-coal from torrefied RDF

Bio-coal from RDF and MSW

Refuse-derived fuel from municipal solid waste, torrefied into a denser, more uniform solid fuel.

Torrefied pellets from agro-waste and sawdust

Torrefied pellets

Agro-waste and sawdust torrefied and pelleted into a fuel that replaces part of the coal in boilers and kilns.

Torrefied paddy straw

Torrefied paddy straw

Rice straw that would otherwise be burned in the field, turned into a coal substitute. Read more.

Fuel or carbon removal

Bio-coal and biochar do different jobs
