AgrotechBiochar from farm waste lifted maize yields up to 29% and rice up to 23%, scientists say
Biochar made by heating straw, wood and crop residue without oxygen raised maize yields by up to 29 per cent and aus rice by 23 per cent alongside balanced fertiliser, and could cut urea use by a quarter, scientists told a BARC workshop.
EnvironmentAfrica should pick carbon removal methods place by place, report says
A report by the African Tech Futures Lab urges a selective, location-specific approach to carbon dioxide removal in Africa, naming biochar and enhanced rock weathering as low-infrastructure options with possible farm benefits.
AgrotechJute sacks and sticks protect fish ponds: BAU-led team in global top six
'The Golden Loop', a team of Bangladeshi students led by BAU, turned waste jute sacks into geotextile to stop pond banks eroding and jute sticks into biochar to clean pond water, reaching the top six of 119 teams in the Food Systems Innovation Challenge 2026 in the Netherlands.
EnvironmentCalifornia almond huller turns shells into biochar at new Delano plant
Treehouse California Almonds and Sitos Group have produced the first load of biochar from almond shells at a 25,000-square-foot slow-pyrolysis plant in Delano, to be mixed with compost and returned to farmland.
AgrotechCotierra raises $3 million to take farm biochar from coffee to cocoa, cotton and citrus
The Swiss climate-tech start-up turns crop residues into biochar in small reactors near where they are produced and returns it to soils, and will use the money to make its system a repeatable hardware and software product.

Hampshire farm trials on-site biochar kiln that stores its heat and logs carbon removal
CapChar's integrated system turns local woodchip into biochar for cattle bedding, banks the pyrolysis heat in a patent-pending thermal battery for drying fuel wood, and measures the carbon removed, about 250 t CO2e expected from the 80-hectare South Downs livestock farm.

Plantd turns its grass-panel factory waste into biochar for farm soils
North Carolina building-materials company Plantd, which was paying $13,000 a month to remove leftover grass biomass, has launched a biochar line made from that waste and is selling it to farmers as a soil amendment.
