A Review Pyrolysis: Different Agricultural Residues and Their Bio-Char Characteristics

Due to the large availability of biomass resources, India has great potential for the production of biochar. Different types of thermochemical even biological processes have been adopted to convert biomass into value‐added products. Among those processes, pyrolysis is more convenient since it has several advantages of storing, transportation, and flexibility in solicitation such as turbines, combustion appliances, boilers, engines, etc. Fig. 1 Overview of the pyrolytic product. Illustrates different types of the existing biomass conversion process with their respective output. The study was undertaken to investigate the properties of various agricultural residues. Until recently, the use of BC (biochar) in agriculture was mainly focused on the application of BC as a soil amendment. However, there are opportunities to investigate in this wide field of study, as there are plenty of potential relationships between various parameters, such as (but not limited to) BC(biochar) feedstock material, dose, and its characteristics, type of soil, plant species, and target elements/compounds of the treatment. Other related aspects that were investigated are BC‐enhanced composting processes and obtaining the BC via pyrolysis of agricultural waste.
