3. Introduction:
Industrial food waste management includes recovering energy from food
waste through techniques such as anaerobic digestion, which helps recycle
food waste into energy and fertilizer.
Bangladesh has many foods industry, Pran is the largest food processors in
Bangladesh. The Pran group include 10 company, the head offices are located
at Dhaka with production facilities in Bangladesh. The Pran agro industry
introduced in Natore .The industry is comprised of automatic rice mill, spice,
peanut, honey ,pickle ,jam and juice processing units, fruit pulping units, cattle
feed units and many other food processing units etc. All these food
processing units produce waste from those food. This waste is include organic
waste.

6. Methodology:
Preliminary research on food waste indicates that every year almost 85 million
tons of food waste is discharged from the food-related industrial units .
Exponentially accelerating worldwide population every year brought about a
high pressure for food and energy to fascinate public demand. Packaging,
distribution, storage, and transportation lack the usefulness of approaches to
waste treatment that result in the immense hype of food wastes . Most organic
food wastes display various textures, pH differences, and are defined by
increasing biological oxygen demand (BOD) and chemical oxygen demand
(COD) values.
Due to the presence of lignocellulose properties and rich cellulose and lignin
content, wastes from the food industry are exceptionally impressive to use as
renewable substrates for transformation procedures.
8. 1. Animal feed:
Most Asian countries like Taiwan, Japan, South Korea have a requirement for
animal feeding. The food wastes are cost-effective alternative to animal feed
rather than carrying them to a landfill. Extra food can also be supplied to pet
food suppliers or zoos. There are many such ways to feed livestock, save
money, and benefit the world.
Food wastes are rich in moisture content around 50–85%, which decreases
shelf-life and make it difficult to incorporate food waste into animal diets
9. 2. Anaerobic digestion:
In this process, the food waste is fragmented, filtered, and used into the
digestion tank, where the digestion takes place at temperature range of 55 to
60 °C. The digestate primarily contain 50% dry solids. Biogas is produced in
this process which is decontaminated and used in the process of power
generation. Since 2006, anaerobic digestion is generally applied to manage
food waste in the European Union and many developing Asian countries .
10. 3. Composting:
Biodegradable yard waste is decomposed in a specially engineered
medium due to a shortage of landfill space. Composting method
implicates the consumption of only biodegradable waste materials.
Co-composting is used to degrade different types of organic matter into
useful compounds called compost.
The composting involves the breakdown of complex biomasses into
simpler compounds that periodically form mature organic composte by
the action of various microbial species.
11. 4. Incineration:
This involves the burning of the solid waste at a very high temperature, until
the waste burns and turn to ash. This process is carried out in different ways
in which extreme amount of heat is supplied when burning the solid waste.
The process was that recycled heat energy through the furnace, and boilers
are called waste-to-energy plant.
5. Landfill:
Creation of landfills or pits and dumps is the major food waste
management method in all advanced countries worldwide.
Many new landfills are collecting potentially hazardous wastes,
reducing toxic landfill gas emissions by converting them to
energy. Landfill has a very high economic and social expense.
12. 6. Enzymes emerging biocatalysts for
biotransformation processes:
Enzymes have been reported for different applications including biofuel production,
laundry detergents, pharmaceutical, food, and biomedical purposes during past few years.
Enzymes are biocatalytic proteins that are commonly used in industrial procedures.
Therefore, there has been an improvement in the global market for industrial enzyme from
2.8 billion USD in 2008 to a projected 6 billion USD in 2016.
Enzymes immobilization on the solid carrier can improve the strength and catalytic
efficiency of the enzymes.
In addition, some substrates are reinforced with the replacement of the enzymes, which is
a different instigation to the enzyme durability. For instance, lipase can generate biodiesel
from fatty acids and alcohols.
13. 7. Renewable energy and biogas from
food-derived wastes:
Biogas is a mixture of gasses produced by the anaerobic decomposition of organic
matter without oxygen, principally carbon dioxide and methane. Biogas may be
derived from agricultural waste, plant materials, municipal waste, manure, green
waste, sewage, and food-derived wastes . Biogas is a renewable source of electricity.
Two approaches for processing biogas are anaerobic digestion of methanogen or
anaerobic species that digest the material in a closed environment and ferment
biodegradable materials. An anaerobic digester, also known as a biodigester or a
bioreactor provides a closed system for biogas generation. Biogas is a renewable
energy supply for the local grid that generates both electricity and heat. Biogas
processing has many benefits for the atmosphere, businesses, and individuals
concerned.

17. Conclusion :
According to a recent study Pran group of industry, FW reduction in many
countries is hampered by surplus food for guests, friends, and family due to
hospitality [4] . Bangladesh is undoubtedly considered a hospitable country.
The offering of abundant meals for visitors is frequently viewed as a symbol
of social standing. Thus, food is regularly discarded in large quantities,
especially at family reunions and other festivities. The government should
approach a comprehensive FW management strategy for Bangladesh as soon
as possible to avert the looming food crisis( Sharma et al. 2021).
