Biomass Pyrolysis Rotary Kiln

Biomass, from wood chips to agricultural residue, is one of the few renewable carbon feedstocks available at scale. A rotary kiln unlocks that carbon by heating biomass in an oxygen-free atmosphere until it thermally breaks down, producing three valuable streams at once: a solid biochar, a combustible syngas, and a condensable bio-oil.

How Biomass Pyrolysis Works

Biomass is fed into an indirectly heated rotary kiln and raised to pyrolysis temperature, typically several hundred degrees Celsius, without oxygen. The material decomposes into volatile gases and vapours, which are drawn off and partially condensed into bio-oil, while the non-condensable syngas can be burned to help heat the kiln. The carbon-rich solid that remains is biochar, a stable form of carbon that can improve soils or serve as a fuel.

Why the Rotary Kiln Suits Biomass

Biomass is variable, moist and bulky, and the rotary kiln’s tumbling action handles that variability while delivering continuous throughput. Its slow rotation gives even heating across the whole feed, so the biochar exits uniform rather than patchy, and its controlled atmosphere lets an operator tune the split between solid, gas and liquid product.

Turn Biomass Into Carbon and Power

Klean’s biomass pyrolysis systems produce biochar and renewable energy from wood and agricultural waste that would otherwise decompose or burn.

Klean Industries delivers turn-key waste-to-energy systems, including a biochar power plant in Japan producing roughly 1,000 tonnes of biochar a year alongside base-load renewable power.
