In this episode, Dr.Arun Bansal and Mr. Puneet Arora discuss how to handle waste with an approach Known as "BioChar" 

In laymen language “char” is a word that is used when some material gets burned and you are left with the remains of the material referred to as  “char”. Basically, it is a type of carbonaceous, solid, and recalcitrant solid which is typically extracted from the pyrolysis of waste biomass. In nature, when the fire broke out in jungles lot of char is produced and a large proportion of it can be classified as “BioChar” or black carbon. A material that burns at a low level of oxygen and in absence of oxygen transforms into Biochar. This process is known as pyrolysis or thermal decomposition. Using homemade or industrial-grade equipment pyrolysis can be used for making biochar. In fact, it can be engineered to suit many applications in agriculture, building material, wellness and many more.

Pyrolysis creates an intermediate fuel by decomposition of plant biomass. Biochar is primarily developed at temperatures ranging from 300 to 1000 degrees Celsius. The absence of oxygen enables a partial burning of organic matter thus producing more waste products such as biochar. Cold temperatures (300°C–600°C) yield a larger amount of char, with higher temperatures creating a more syrupy liquid. The best-known technology applied in waste-to-energy products is high-temperature pyrolysis of biomass materials yielding approximately 20 per cent syngas, a combustible gas used in internal combustion engines, consisting of mainly carbon monoxide and hydrogen, along with bio-oil and biochar.
