Agroindustry wastes: biofuels and biomaterials feedstocks for sustainable rural development 383

currently being made for the upgrading of existing biorefinery frameworks to fully
attain the sustainability standards required to warrant their full-scale implementa-
tion. As a consequence of the mandatory inclusion of the sustainability goals into
the biorefinery concept and the escalating concern on the “food-fuel conflict,” the
biorefineries based on abundant agroindustry wastes are gathering quick popularity.
Indian agroindustry wastes display an extraordinary variety of lignocellulosic bio-
mass and round-the-year availability in ample amounts. Unfortunately, due to lack
of awareness and poor valorization, these valuable wastes are often destroyed in
mass scale for waste management instead of being utilized in a productive way.
These residues can be used as an alternate source for the production of different
products such as biogas, biofuel, and as the raw material in various researches and
industries. The use of agroindustrial wastes as raw materials can help to reduce the
production cost and also reduce the pollution load from the environment.
Agroindustrial wastes are used for manufacturing of biofuels, enzymes, vitamins,
antioxidants, animal feed, antibiotics, and other chemicals through various pro-
cesses. The major focus of the present chapter is to present the agroindustry sce-
nario in the world with special reference to India, the adaptability of these wastes to
products through cascading of various approaches in a biorefinery mode. The
implementation of biorefinery unit will help in complete utilization of bio-based
resources to produce some value-added end products in an efficient way for sustain-
able development of rural India.
Though agroindustries are considered one of the environment-friendly systems
of production, but wastes generated from agroindustries need to be taken care.
Management of these wastes can be done with appropriate segregation at the source
followed by conversion and utilization. A common strategy for their utilization and
modification is not possible because of their compositional differences, as they are
derived from wide arrays of agroindustrial processes. So, knowledge on the type of
waste residues generated from different food industries and their composition in
terms of the nutritive values is of utmost necessity. The characterization of the com-
pounds of these residues will help to take up the enterprise for a profitable venture
in waste valorization.
