Biochar carbon removal (also called pyrogenic carbon capture and storage) is a negative emissions technology. It involves the production of biochar through pyrolysis of residual biomass and the subsequent application of the biochar in soils or durable materials (e.g. cement, tar).
A pile of biochar Biochar mixture ready for soil application. Biochar is charcoal, sometimes modified, that is intended for organic use, as in soil. It is the lightweight black remnants remaining after the pyrolysis of biomass, consisting of carbon and ashes; and is a form of charcoal. [1]
"Biochar is a promising approach to carbon removal because it has the ability to scale worldwide, using existing technology, with positive side effects for soil health," said Randy Spock, Google's ...
Jim Doten, the city's carbon sequestration program manager, said producing municipal biochar will be Minneapolis' first initiative under that program as it tries to achieve carbon neutrality by ...
Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon dioxide (CO 2) that is produced. Greenhouse gas emissions from bioenergy can be low because when vegetation is harvested for bioenergy, new vegetation can grow that will absorb CO 2 from the air through ...
A University of Florida student urges building industry to adopt use of biochar as way to reduce CO2 emissions, increase sustainable construction.
Agricultural methods for carbon farming include adjusting how tillage and livestock grazing is done, using organic mulch or compost, working with biochar and terra preta, and changing the crop types. Methods used in forestry include reforestation and bamboo farming .
Pyrolysis is a process where biomass is partially combusted in an oxygen-limited environment, which produces a char rich in carbon. This char can be distributed in soils as a soil amendment.
