Technology built for real-world biomass.

01Biomass Pyrolysis

24 TPD Biomass Pyrolysis

Designed and operated by a team that ran this technology themselves before offering it for sale.

02Torrefaction

Biomass Torrefaction

Torrefaction is mild pyrolysis — biomass is heated in a low-oxygen environment to around 200–300°C, just enough to drive off moisture and volatiles without fully carbonizing the material.

03Steam Dryer

Biomass Drying

A steam dryer avoids direct flame or combustion-gas contact entirely. Moisture is removed using closed-loop process steam, which means gentler, more even drying, no oxidation or fire risk, and lower energy loss.

04CBG

Modular CBG System

Compressed Biogas (CBG) is renewable methane produced by upgrading biogas from organic waste. Our 50–1,000 kg/day skid-based systems enable distributed production close to the feedstock source, with modular capacity and simpler deployment.

05Convergent

Carbon MRV Platform

Convergent is Tanren's monitoring, reporting, and verification platform for carbon removal projects — starting with biochar.

Engineering that has held up in operation, not just on paper.

That's the difference between engineering on paper and engineering that holds up.
