Biochar made from corn cobs can remove microplastics and ammonia from water, offering a low-cost, reusable filter made from ...

Corn cob biochar made from farm waste can remove up to two thirds of ammonia and almost all micro and nanoplastics from water ...

On a site next to a sawmill in Waverly, Virginia, a startup takes sawdust and offcuts from the mill and heats it up to turn it into biochar, a material that can store carbon for hundreds or thousands ...

Biochar is a form of charcoal (mostly carbon) produced by heating organic matter in the absence of oxygen, a process called pyrolysis. This avoids the production of carbon dioxide and locks up the ...

Nick Cuchetti, a farmer and board secretary of Missouri Organic Association, holds biochar at Oaklee Rose Farm in Luebbering, Missouri. Biochar is an organic waste material that can help improve soil ...

I said in my recent book that perhaps the only tool we had to bring carbon dioxide back to pre-industrial levels was to let the biosphere pump it from the air for us. It currently removes 550bn tons a ...

Biochar is a carbon-rich material that is made from biomass through a thermochemical conversion process known as pyrolysis. Don’t worry if that all sounds like a mouthful—read on for an introduction ...

Improve your soil by making biochar in the ground. DIY biochar enhances nutrient availability and also enables soil to retain nutrients longer. Last year, I committed one of the great sins of ...

Biochar, a charcoal-like material derived from plant biomass, has long been hailed as a promising tool for carbon dioxide removal. However, a new study by Stanford researchers highlights a critical ...

In the late 1990s, soil scientist Johannes Lehmann was working in the central Amazon to help restore degraded soils. Other researchers had discovered that the region’s fertile terra preta, meaning ...

Biochar removes CO2 from the air, improves soil quality, creates clean energy, and it's surprisingly easy to come by. Shea Gunther is a writer, entrepreneur, and podcaster living in Portland, Maine.
