Pellet Biochar: An Environmental Remedy

Abstract

With recent impetus on building of smart cities, modern urban settlements and expansion of established settlements, solid waste management, sufficient energy supply, water pollution and water borne diseases have become an inseparable trouble. The need of the hour, thus, is an efficient and rapid remedy to these issues which is not only feasible but economically viable as well. Present study concentrates on how horticultural and commercial organic waste can be converted to pellets and after further processing can be utilised to combat water pollution and production of energy. Pellets are condensed product of above mentioned waste which is capable of utilizing these waste that is generated each day in tons. Pellets can be utilized directly as an alternate mode of fuel in certain areas. Analysis of pellets makes it clear that it’s a cleaner and greener substitute to coal. Pellets after combustion gives rise to biochar which finds wide application in water purification and hence is considered as a remedy to water pollution. Pellet biochar possesses certain specific architecture and molecular composition which varies with temperature, residual time, feedstock type and heat transfer rate. On gasification of pellets, syngas is produced which can be used for running engines as well as generating electricity.
