It is produced by heating biomass in an oxygen-free environment, a process known as pyrolysis, which results in the production of a carbon-rich solid material. Biochar has a high surface area and a porous structure, which makes it highly absorbent and allows it to hold onto nutrients and water.

Biochar has several potential benefits as a soil amendment:

  • It can improve soil structure and fertility,
  • increase water-holding capacity,
  • reduce nutrient leaching.
  • increase the population of beneficial soil microorganisms,
  • it can serve as a long-term carbon sink, sequestering carbon in the soil for hundreds or even thousands of years.

Biochar is also being explored as a potential solution to the problem of waste management. It can be produced from a variety of organic waste materials, and it provides an alternative to burning or disposing of waste in landfills.

Overall, biochar shows promise as a sustainable and beneficial addition to soil and as a potential waste management solution. However, more research is needed to fully understand its effects and potential uses.
