Haiqi's Puro earth approved pyrolysis equipment is suitable for wooden waste, straw, nut shells, EFB, etc. The biochar produced can be used for carbon removal.

In September 2024, HaiQi Group, as an official member of the United Nations Industrial Development Organization (UNIDO) Alliance, was honored to participate in the Biomass Negative Carbon Sustainable Environmental Protection Forum. The event gathered global leaders in green technology and carbon removal to exchange innovations, strategies, and explore opportunities for collaboration toward a more sustainable future.

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.
