A new study reveals how a simple, low-cost material could significantly boost the production of clean hydrogen fuel from waste. Researchers have demonstrated that biochar, a carbon-rich material made ...

Biochar can help turn agricultural waste into clean hydrogen fuel while cutting carbon pollution, according to a new study in the journal Biochar. Researchers report that a simple two stage catalytic ...

Production capacity for the material, which is created by treating organic matter at high temperatures, nearly doubled in two ...

Neumann Kaffee Gruppe and its partners are scaling biochar in Colombia, transforming coffee waste into a super substance ...

A technology has been developed to quickly convert livestock manure, a significant issue in animal farming, into valuable "black gold" rich in carbon within a day. Dr. Yoo Ji-ho and his research team ...

When it comes to building a circular economy, every kind of waste is either eliminated or recycled into new valuable materials. But waste comes in all shapes and sizes—there’s no single “magic bullet” ...

New research suggests coffee waste could have a future beyond compost, with applications that include renewable fuel and carbon storage.

AMES, Iowa – Heat up stalks, stems, leaves or wood in a reactor with little or no oxygen (in a process called pyrolysis) and you get bio-oil for fuel and biochar for fertilizer. There’s always a ...

Concrete is one of the most common materials on Earth, thanks to its high strength and low cost – but it’s also one of the largest single sources of carbon dioxide emissions. Engineers at Washington ...
