Impact of pyrolysis techniques on biochar characteristics: Application to soil

Abstract

Society currently faces global environmental challenges of the burning of waste plants reside which demand innovative, interdisciplinary and complex solutions. In India about 500 million tons agricultural and agro-industrial residues are being generated annually in the country. A major amount of this agricultural residue farmers treats as waste, are burn in field itself. Hence, there is need to combat these problems through a sustainable management system, which will revive depletion of waste generated from agriculture itself. Conversion of this agricultural waste into biochar through pyrolysis could be a positive solution for minimizing agricultural waste. Production of biochar also offers many opportunities for enhancing soil Physico-chemical characteristics and carbon sequestration. However these characteristics alter with different factors like type and temperature of pyrolysis, biomass holding time. In the present chapter the detailed information of pyrolysis techniques and their impact on soil fertility are discussed.
