fuel, including energy products, such as eco-fuel, electricity, polymer products, syn-
thesis gas, and oils, and value-added chemical and pharmaceutical products. In the
biorefinery advancements, pyrolysis, aging, gasification, anaerobic absorption, cre-
mation, rejected inferred fuel, and plasma circular segment gasification, as exam-
ples, are the compelling biorefinery techniques to deliver powers from nonfood
feedstock that incorporate grain straw, sugarcane bagasse, perpetual grasses, corn
stover, farming and backwoods biomass squander, and civil and modern natural
waste (Rathi, 2006; Miandad et al., 2016).
The generation of FW by the end purchaser is caused by finished or nonproper
acquiring, terrible capacity conditions, overarrangement, portioning, cooking, and
perplexity between the terms “best before” or “use by” dates. The phase of FW at
family-unit level is impacted by a progression of interconnected elements, primarily
sociodemographic characters of the family, utilization conduct, and sustenance
designs. Food loss (FL) and FW phase create an effect at a natural, social, and pru-
dent dimension. The food industry discharges an assortment of wastes—for exam-
ple, foods grown from the ground wastes, meat and fish cooking wastes— and wet
wastes—for example, whey and wastewater. These wastes should be treated and
converted into the nontoxic form; in most of the industries the waste management
is an inevitable problem in terms of the today’s world that has to protect environ-
ment and production sustainability instantaneously. These types of food industry
wastes can be treated through biorefinery processes. Apart from the food industry, a
large quantity of FWs is generated due to various other sources and several human
anthropogenic activities. To valorize, these wastes go through a pretreatment pro-
cess (biological, physical, mechanical, and chemical) for further use. Then the pre-
treated FWs further undergo a conversion process that includes aerobic
fermentation and anaerobic digestion (AD) and produce several valuable products
such as biofuels, bioplastic, biochemical, biogas, and biofertilizer.
This chapter mostly focuses on the food-industry wastes, for example, generation
of FWs, their energy investigation, enhancement of item yield and cost-viability of
creation process through incorporated bioprocess, their connections with various
biorefinery procedure and biomass chain, FW biorefinery process, recycling and
reuse of these wastes, distinctive difficulties for the transformation of the FW
through biorefinery process, and developments in FW biorefinery process.

18.2 Generation of food waste

Thirty-three percent of nourishment items are squandered among field and fork.
The FAO describes nourishment squander as sustenance which was at first con-
veyed for human usage anyway and was not eaten up by individuals, rather it was
composed into a nonnourishment use (for human), feed for creature, or waste
exchange (e.g., feedstock to an anaerobic retention plant or incinerator, exchange at
a landfill). FW is accumulated into three arrangements: (1) avoidable FW shows
nourishment that could have been eaten at some point or another previous being
