By converting the biomass into biochar, the carbon is sequestered in a stabilised form.The IPCC has officially classified biochar as an emissions-negative technology with multiple synergistic benefits to combat climate change.

Carbon sinks are the process, activity or mechanism that removes CO2 from the air. As a new type of carbon sink, biochar is making a positive impact on the earth.

Biochar is a solid material obtained by high temperature pyrolysis of biomass-based feedstock. At high temperatures and in an anaerobic environment, the volatile organic compounds (VOCs) in the biomass feedstock are removed, leaving a stable carbonaceous residue, which is called biochar. It can exist in the soil for thousands of years.

On 1 August 2024, Haiqi successfully delivered a 1 tonne biomass steam generator to a customer in Thailand.

The yield of biochar is not fixed. It is related to many factors. Any slight difference in feedstock, pyrolysis time, pyrolysis speed, etc. will affect the biochar yield.

Biomass pyrolysis converts feed materials such as straw, waste wood, and nut shells into biochar, syngas, and green electricity to maximize resource utilization.
