Meet BioCarbon, the climate tech startup revolutionising green steel manufacturing.

From woody wastes we produce a charcoal briquette that replaces coal in steelmaking, a clean burning gas and a liquid biostimulant for agriculture.

Customer Focus‚Äć

We target steelmakers for our briquette product and farmers for our raw char and liquid products.

From this to....
.... to this


We have a working pilot plant, are in negotiations with steelmakers for long term use of our briquette and have a site with ample woody waste to process.   What we need now is capital to make that project happen. 


  • Our briquettes are the first of their kind in the world.¬† We have replaced coal based coke in trials at two steel mills.¬†¬†
  • Our charcoal making process is eminently scaleable and produces charcoal more efficiently and economically than any other technology.
  • Excess charcoal (Biochar) can be used in agriculture and reduces CO2 in the atmosphere.¬† Biochar is carbon storage.¬†
