The resulting paste is extruded into high-density briquettes, which need to undergrow a drying process.
Depending on the type of briquettes required, different kind of charred biomass can be combined. The finely ground char is thoroughly mixed with water and natural binder.
In traditional charcoal kilns, most of the gases are vented to the atmosphere. In the kilns used by OTAGO, nearly all gases are burned. This minimizes pollution and also provides heat to dry the briquettes.
OTAGO Char-briquettes are made from recycled biomass wastes, such as coconut shells, and can burn longer than traditional wood charcoal, with no sparks, no smell and no smoke.
