BiGchar : Biochar Production Technology

The BiGchar (Black is Green) patented biochar production technology features durability, mobility, and accepts a wide range of feedstocks.  Designed and built in Australia by Pyrocal, it has seen many years of development and field deployment and has matured into a tough, efficient, and user friendly machine that can be installed and moved with relative ease.
