This water entered small woodchip bioreactors, then flowed "downstream" through tubes filled with biochar. On the other end of the system, which they called B 2 (bioreactor-biochar), the ...

What if farmers could not only prevent excess phosphorus from polluting downstream waterways, but also recycle that nutrient ...

Biochar removed a robust 92.6% of plastic particles from study samples, demonstrating an ability to filter the tiny pollutants ... the oceans and our drinking water. There's even evidence some ...

University of Illinois Urbana-Champaign researchers find designer biochar can inexpensively and sustainably remove up to 41% of dissolved phosphorus in farm drainage water.

Biochar is a charcoal-like substance that ... a carbon-negative additive to materials like asphalt and concrete, and an air or water filter for various pollutants – just like activated charcoal.
