residues These residues include sawdust, slabs and chips generated as residues during the wood processing. The amount of residues generated in a sawmill depends on the type of technology used and its efficiency. Often, these residues are not fully utilized due to the lack of demand in the immediate vicinity of the processing plant. Woodfuel

Crop Residue (CR) Surplus. The amount of surplus crop residue available in India is about 141 million tons a year, out of which 92 mt is burned each year. 7 The two crops as rice and wheat are produced large amount of residues in India. Globally, biomass production from agriculture is pegged at 140 billion metric tons reported in Feb. 2019.

Crop residues represent substantial global stores of fiber, energy, and plant nutrients, even when they are compared with the largest commercial sources of these commodities—wood pulp, fossil fuels, and synthetic fertilizers. Residue composition is dominated by cellulose, hemicellu-lose, and lignin ( Barreveld 1989 ).
