Biochar/Iron Co-Production System

Idea to couple the production of biochar with the reduction of iron ore to metallic iron. The pyrolysis gas generated during char production is not flared off but used in a rotary kiln for iron reduction. The process is carbon-negative. Heat is another co-product that could be used for space heating, greenhouses, etc.

Similar concept to this one: Biochar-Lime Co-production System.
