disposed off in spite of the way that a ton of it would have been unappetizing at the
motivation behind the exchange. (2) Unavoidable FW notices to the bit of food that
is not regularly eaten, including things, for instance, banana skins, apple cores, egg-
shells, and chicken bones. (3) In food-making industries, waste is delivered from
the division of the perfect things from undesired reactions. Such food-industry
waste is product explicit, and in this way, the portion of the waste does not differ
altogether as the last item should have a steady quality. Various efforts have been
made to use the biodegradable part of food processing waste to create valuable
items. In developing countries the FW percentage is smaller than FL. In these coun-
tries, FL takes place at various stages, such as agricultural production, postharvest
handling, and storage and processing. For instance, due to untimely reaping, poor
stockpiling, and the absence of framework and preparing offices, an insufficient
market framework results in nourishment misfortunes. In developed countries, both
FWs and FLs are high in distribution and consumption stages. As reported by the
World Biogas Association, on an average, around 180 kg of food is wasted by a sin-
gle person per year in the European Union (Jain et al., 2018).
Four different sources, that is, manufacturing industries, wholesale and retail,
food services, and households, majorly produce FWs, which is shown in Fig. 18.1.
There are few factors or functions in these sources that drive the FW. The driving
factors in the manufacturing industries have been prevailing over generations
because of its pressure to legally meet binding necessities, quality standard for pro-
duction, damaged items, cheap disposal options, unappetizing parts that generate
FW in the manufacturing zone. In the food-services sector the wastes are generated
by the following factors: absence of adaptability in segment sizes, insufficient
arranging in determining and ordering ingredients, consumer demeanors toward tak-
ing scraps home, refused food due not meeting client inclinations.
FWs are also generated due to several household functions or factors. Although
waste in food assembling and retail is noteworthy, it is not at indistinguishable scale
from family-unit FW. In the United Kingdom, for instance, 2.0 Mt wastes emerge
