WASTE
Waste is everything that no longer has a use or purpose and
need to be disposed of. Waste is defined as
"Any discarded, rejected, unwanted, surplus, or abandoned
matter intended for recycling, reprocessing, recovery, re-use or purification
by a separate operation from that which produced the matter or for sale, whether
of any value or not"
TYPES OF WASTE
Waste can be divided into three types
- Hazardous Waste: Washing liquids, polishing chemicals etc.
- Non-hazardous Waste: Paper, Cardboard, Glass etc.
- Mirror Waste: Food waste, pesticides etc.
WASTAGE OF FOOD
There are two kinds of wasted food
- Food Waste
- Food Loss
FOOD WASTE
Food waste is defined as:
Food discarded by retailers due to color or appearance and
plate waste by consumer.
Food waste includes the half-eaten meal left on the plate at
a restaurant, food scrapes from preparing a meat at home and the sour milk o
family pour down the drain.
According to FAO:
"Food waste refers to food appropriate for human consumption being discarded whether or not after it is kept beyond its expiry date or left to spoil. Often this is because food has spoiled but it can for other reasons such as oversupply due to markets, or individual consumer shopping/ eating habits."
FOOD LOSS
According to FAO:
"Food loss refers to a decrease in mass (dry matter) or
nutritional value (quality) of food that was originally intended for human
consumption. These losses are mainly caused by inefficiencies in the food supply
chains, such as poor infrastructure and logostics, lack of technology,
insufficient skills, knowledge and management capacity of supply chain actors
and lack of access to markets."
Edible food discarded at every point along the food chain,
on farms and fishing boats, during processing and distribution, in retail
stores, in restaurants and at home. Food loss occurs for many reasons, with
some types of loss (such as spoilage) occurring at every stage of the
production and supply. Between the farm gate and retail stages, food loss can
arise from problems during drying, milling, transporting or processing that
expose food to damage by insects, rodents, birds, molds and bacteria. At the
retail level equipment malfunction ( such
as faculty cold storage) over-ordering and cutting of blemished produce
can result in food loss. Consumer also contribute to food loss when they buy or
cook more than they need and choose to throw out the extras.
FOOD LOSS AND WASTE
Technically, food loss and waste refer to the decrease in
mass (quantitative) or nutritional value (qualitative) of food-edible parts
throughout the supply chain that was intended for human consumption. Food was
originally meant for human consumption but for various reasons is removed from the
human food chain is considered as food loss or waste.
From farm to fork, food is lost or wasted at every step of the journey. Food loss takes place on the farm and through supply chains, due to sub-optimal farming methods, poor storage and inflexible distribution or buying practices. Sometime its something as simple as a bag not being strong enough to hold its contents and food like rice leaking out of small tears. People are also generating huge amount of food waste at the point of consumption. Unclear labelling and simply not eating everything before it goes of all contribute. Most uneaten food winds up in landfills, where it rots and releases green house gas emission.
