On the basis of geographical and seasonal availability, TOESL manages the supply chain of various agro-waste and industrial waste biomass fuels such as paddy straw, baggase (sugarcane), ground nut shell, cashew nut shell, soya husk, saw dust, coffee husk, corn cobs, etc. across India in the form of loose fuel, briquettes and pellets.
Fuel supply is critical to the reliable and efficient operation of any biomass based system. Biomass fuel is primarily classified into the following categories:
-> Agricultural waste viz. corn stalks, straw, seed hulls, rice husk, bagasse, nutshells, mustard & cotton stalk, manure from cattle, poultry, and hogs, etc.
-> Wood materials viz. wood / bark, sawdust, timber slash, mill scrap, forest waste.
-> Municipal waste viz. waste paper and yard clippings etc.
-> Energy crops viz. switchgrass, jatropa, prairie bluestem, corn, soybean etc.
There are, however, a number of issues that constrain the wide spread use of biomass for industrial and commercial applications:
-> Wide geographical spread
-> Seasonal availability
-> High moisture content
-> Natural decay tendency
-> High handling, transportation & storage cost
-> Unorganised Supply Chain
-> No standards for classification, grading & quality
-> Choking/Fouling tendency
-> Lack of established market pricing mechanism.
