In 1925, Japan independently started developing technology to harness the energy from sawdust briquettes, known as "Ogalite".

Sawdust briquettes have developed over time with two distinct types: those with holes through the centre, and those that are solid.

Hexagonal sawdust briquette charcoal are made by compressing sawdust without binders or additives.

For example, Croatia now exports sawdust briquettes to Austria, and Sweden is importing energy wood chips from as far away as West Canada.

Hexagonal Sawdust Briquette Charcoal is the preferred charcoal in countries like Taiwan, Korea, Middle East, Greece.

Police in the northern city of Hamburg said Tuesday they found at the port 1,244 packs of the highest quality cocaine hidden in a container from Paraguay full of sawdust briquettes.
