What are the main reasons for food waste?
- Improper storage – food not being used before it goes bad. ...
- Over-Preparing – cooking or serving too much food. ...
- Large Portions – commonly observed at restaurants, increased portion size largely contributes to waste.
The main takeaway this month is that there are two main types of food waste – preventable and non-edible. Non-edible food waste is unavoidable…it's the banana peels and meat bones. The Love Food, Fight Waste program is working hard to reduce the preventable food waste.
- Uneaten food that is thrown out at homes, stores, and restaurants.
- Crops left in fields because of low crop prices or too many of the same crops being available.
- Problems during the manufacturing and transportation of food.
- Food not meeting retailers' standards for color and appearance.
[32], where food waste falls into the following categories: organic crop residue (including fruits and vegetables), catering waste, animal by-products, packaging, mixed food waste and domestic waste.
- Over-purchasing, lack of meal planning, and limited use of grocery lists.
- Spoilage due to improper storage.
- Concern for food safety and freshness - poor understanding of shelf life; confusing “sell by”, “use by”, “best before”, and “expiration” date labels.
Two main waste categories can be established based on the distinct legislation and policy instruments usually in place: non-hazardous or solid waste; and hazardous waste.
For the purposes of this review these sources are defined as giving rise to four major categories of waste: municipal solid waste, industrial waste, agricultural waste and hazardous waste.
Food spoilage, whether real or perceived, is one of the biggest reasons people throw out food. More than 80 percent10 of Americans discard perfectly good, consumable food simply because they misunderstand expiration labels.

What are the four main sources of waste?
Sources of waste can be broadly classified into four types: Industrial, Commercial, Domestic, and Agricultural.
Food waste includes all food intended for human consumption that never reaches us and edible food that consumers throw away. Perfectly edible fresh produce is often turned away from supermarket shelves because it does not meet the optimal criteria for consumers, such as shape, size and colour.
Food “waste” refers to food that is fit for consumption but consciously discarded at the retail or consumption phases.
Wasted food that ends up in the garbage, and ultimately the landfill, produces methane—a greenhouse gas that is 21 times more potent than carbon dioxide. It's estimated that 7% of greenhouse gases produced globally are due to preventable food waste.
Food in landfill breaks down in a way that can create greenhouse gases, including methane, which affect air quality and public health. When we waste food, we also waste the resources used to grow our food (water, soils and energy) and all the energy used to process, package and transport food from markets to our homes.

Major Causes of Solid Waste Pollution
- Commercial establishments.
- Residential houses.
- Debris from construction and demolition.
- Debris from roads (such as asphalt and scrap metal)
- Scrap from vehicles.
- Agriculture.
Biodegradable waste is also known as moist waste. This can be composted to obtain manure. Biodegradable wastes decompose themselves over a period of time depending on the material. Non-biodegradable waste is known as dry waste, for example old newspapers, plastics, etc.
Nitrogen-containing wastes, such as ammonia, urea, and uric acid, are removed through the excretory system. This system includes the kidneys, ureters, bladder, and urethra. Waste gases like carbon dioxide are removed through the respiratory system through a process of gas exchange.
Muda = “Waste” or failures of people or processes to efficiently deliver product. Mura = “Unevenness”, or failures related to unpredictable or inconsistent outputs. Muri = “Overburden”, or failures of standardization to create efficient process.
As mentioned, any waste type which cannot be decomposed by natural or biological processes is considered as non-biodegradable waste. Besides plastic, glass and metals, it includes cardboard, paper, old clothes, thermocol sheets, cans, man-made polymer, biomedical waste, chemical waste, electronics, batteries etc.
What are the 2 classification of waste according to their effects on human health and environment?
There are two primary types of solid waste -– municipal solid waste (trash or garbage) and industrial waste (a wide variety of non-hazardous materials resulting from the production of goods and products. Conversely, hazardous waste is waste that is dangerous or potentially harmful to our health or the environment.
China and India produce more household food waste than any other country worldwide at an estimated 92 million and 69 million metric tons every year, respectively. This is unsurprising, considering both countries have by far the largest populations globally.
Agricultural production, at 33 percent, is responsible for the greatest amount of total food wastage volumes.
China came first with an estimated 91.6 million tonnes of discarded food annually, followed by India's 68.8 million tonnes. Elsewhere, U.S. households throw away an estimated 19.4 million tonnes of food every year while an estimated five to six million tonnes goes into the garbage in France and Germany.
