Crop waste conversion into biochar: an overview
(Elsevier, 2024) Rini Labanya; Parmanand Sahu; Sandip Mandal; Shiv Vendra Singh; Ram Swaroop Meena
The level of CO2 in the atmospheric carbon pool can be reduced to some extent by utilizing biochar technology which is realized by adding a recalcitrant form of carbon in the soil. Utilizing biochar effectively may make it possible to control soil health and encourage fertility. Millions of tonnes of biomass and crop waste that aren't used as animal feed might be converted into biochar to boost the carbon content of the soil. The high surface area, cation exchnage capacity, high water-holding capacity, pore size; volume, and distribution, as well as molecular structure of biochar, among other chemical, physical, and biological characteristics, can increase nutrient availability and microbial communities for enhancing soil quality. Biochar also reduces the greenhouse gas emission from crop fields and acts as natural filtration media for water and air purification. It can also be effectively used for soil health remediation and reclamation of degraded soils. Biochar has high adsorption properties which help in the removal of heavy metals from wastewater. Thus, biochar has a diverse arena of applications and can be easily derived from any lignocellulosic biomass. © 2024 by Elsevier Inc.
