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.
When we waste food, we also waste all the energy and water it takes to grow, harvest, transport, and package it. And if food goes to the landfill and rots, it produces methane—a greenhouse gas even more potent than carbon dioxide.

Solid wastes – These are the unwanted substances that are discarded by human society. These include urban wastes, industrial wastes, agricultural wastes, biomedical wastes and radioactive wastes. Liquid wastes – Wastes generated from washing, flushing or manufacturing processes of industries are called liquid wastes.

Where is food waste a major problem?
Australian households account for the majority of food waste (2.46 million tonnes) 70% of the 7.6 million tonnes of food wasted in Australia every year is edible. Australian households throw away around one in five bags of groceries, equal to around 312kg per person.
- 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.
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.

Sources of waste can be broadly classified into four types: Industrial, Commercial, Domestic, and Agricultural.
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.
Food Waste Is a Social Issue
It is a social issue because food loss means a loss of money for the current population and waste of resources leading to inequality in food availability for the future population.
Every year in the United States, approximately 31% (133 billion pounds) of the overall food supply is wasted, which impacts food security, resource conservation, and contributes to the 18% of total U.S. methane emissions that come from landfills.

- Excessive transportation.
What are the 7 sources of waste?

Air pollution, climate change, soil and water contamination…
Poor waste management contributes to climate change and air pollution, and directly affects many ecosystems and species. Landfills, considered the last resort in the waste hierarchy, release methane, a very powerful greenhouse gas linked to climate change.
Organic waste is any material that is biodegradable and comes from either a plant or an animal. Biodegradable waste is organic material that can be broken into carbon dioxide, methane or simple organic molecules.
Waste is considered toxic if it is poisonous, radioactive, explosive, carcinogenic (causing cancer), mutagenic (causing damage to chromosomes), teratogenic (causing birth defects), or bioaccumulative (that is, increasing in concentration at the higher ends of food chains).
Various factors cause food spoilage, making items unsuitable for consumption. Light, oxygen, heat, humidity, temperature and spoilage bacteria can all affect both safety and quality of perishable foods. When subject to these factors, foods will gradually deteriorate.
The root is complex and multifaceted, with waste coming first from America's homes (43 percent) and restaurants, grocery stores and food service companies (40 percent), where people throw out food, followed by farms (16 percent) and manufacturers (2 percent), where too much food is produced.
