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).
The word "biochar" is a late-20th century English neologism derived from the Greek word ' βίος ' (bios, 'life') and 'char' (charcoal produced by carbonization of biomass). [8] It is recognized as charcoal that participates in biological processes found in soil, aquatic habitats, and animal digestive systems.

In the soil, the biochar carbon is unavailable for oxidation to CO 2 and consequential atmospheric release. However concerns have been raised about biochar potentially accelerating release of the carbon already present in the soil. [99] [needs update] Terra preta, an anthropogenic, high-carbon soil, is also being investigated as a sequestration ...
At the time of writing, the national average price of regular gas is $3.62 per gallon, $0.02 higher than this time last year. Drivers who use premium gas are paying $0.07 more this year than last ...
A top-lit updraft gasifier (also known as a TLUD) is a micro-kiln used to produce charcoal, especially biochar, and heat for cooking. [1] A TLUD pyrolyzes organic material, including wood or manure, and uses a reburner to eliminate volatile byproducts of pyrolization.
One carbon credit is equal to one free ton of carbon dioxide to be emitted into the atmosphere. India has started to replace charcoal with biomass briquettes in regards to boiler fuel, especially in the southern parts of the country because the biomass briquettes can be created domestically, depending on the availability of land.
