1. Causes of food waste

Food waste can occur at the stages of production, processing, retailing, and

consumption, by farmers, by the food industry, by retailers and by consumers.


Food waste occurs from the beginning of food production. During growing,

crops are quite likely to suffer pest infestations and severe weather, which will

destroy the plants. When you harvest immature crops, or discard part of a crop

no matter they are unavailable to use or not to standard, food waste will

consequently form.

-Food processing

In storage, considerable quantitative losses can be attributed to pests and

micro-organisms due to high heat and ambient humidity, while these factors

combined with the action of micro-organisms lead to qualitative losses such as

losses in the nutritional value, caloric value and edibility of crops. Further

losses are generated in the handling of food and by shrinkage in weight or



Although packaging avoids considerable food waste by protecting food from

damage, as well as preserving its freshness, it can compromise efforts to

reduce food waste in other ways, such as by contaminating waste that could

be used for animal feedstocks.

Retail stores can throw away large quantities of food which passed their best

before, sell-by or use-by dates, which might occur due to stock management









processors plan to produce more than actually required to avoid contracts with

retailers cancelled by failure to supply agreed quantities. Surplus production is

often simply disposed, becoming food waste.


Lack of shopping planning or wrongly anticipating the number of clients in

catering, confusion about "best before" and" use by" date labels, lack of

knowledge on how to cook with leftovers all contribute to food waste.

2. Utilizing Food Waste by Composting

One of the solutions for food waste is composting, a natural process of

decomposition and recycling of organic material into a humus rich soil

amendment known as compost. If land is available, you may compost the food

waste on-site in rows or bins. However, if the volumes are large, you can turn

the compost by compost turner in the form of windrow-a long, narrow pile that

are turned when required based on temperature and oxygen requirements.

The market for compost is one of increasing demand. Food scrap compost is

generally higher in nutrient value and lower in contamination than most other

types of compost, thus making it more valuable in the market.

3. Applications for Finished Compost

* Used to improve soil structure, infiltration rate, water holding capacity, and

tilth, increasing soil microorganism populations, soil organic matter and


* Used as fertilizer supplement for nitrogen, phosphorous, potassium, and

trace elements.

* Used to suppress insect pests and soilborne plant pathogens.

* Used to increase pasture quality in intensively managed grazing systems.

* Used as mulch for trees, orchards, landscapes, lawns, gardens, and makes

an excellent potting mix.

Additional uses for compost include vegetable production, field crops, annual

forest plantings, sod farms, greenhouse crops, mined lands, roads, and

recreation areas such as golf courses, trails, athletic fields, and parks.
