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
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.
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
* 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.
