VALORIZATION OF VARIOUS AGRICULTURAL WASTE RESIDUES AND ITS BIO-CHAR PROPERTIES PRODUCED THROUGH GASIFICATION AND PYROLYSIS: A REVIEW.

India has significant potential for producing bio-char due to the abundance of biomass resources. Numerous thermochemical and even biological techniques have been used to transform biomass into products with added value. Pyrolysis is the most practical of these processes since it offers a number of benefits for transportation, storage, and flexibility in solicitation, including turbines, combustion appliances, boilers, engines, etc. Fig. 1 shows the many types of current biomass conversion processes and their corresponding outputs. The study was conducted to look at the characteristics of various agricultural leftovers. Up until recently, the majority of BC's use in agriculture was around its use as a soil supplement. However, there are opportunities for further research in this broad area of study because there are many possible connections between different parameters, including but not limited to the BC's feedstock material, dose and its properties, type of soil, plant species and target elements/compounds of the treatment. The pyrolysis of agricultural waste to produce BC and BC-enhanced composting methods are two more related topics that have been researched. [ABSTRACT FROM AUTHOR]
