A product or substance that is no longer suitable for its intended use is referred to as waste. Waste comes from four different types of sources: industrial, commercial, domestic, and agricultural.
Industrial waste is the waste created by industrial activity which includes any material that is made unusable during a manufacturing process, such as that of factories, mills, and mining activities. Some examples of industrial waste are - chemicals, oils, solvents, dirt and gravel, many harmful gases etc.
paper, cardboard, cans, and food wrappers etc. are some examples of commercial waste.
The term domestic waste, also known as household waste, comes from the discarded items produced by households. Some domestic waste includes – food waste, rotten vegetables and fruits etc.
Agricultural waste is made up of plant residues from farming. These effluents arise from horticulture and arable land. It also includes the animal waste.

There are two main categories of waste they are
A biodegradable material can be defined as a waste material which can be decomposed by bacteria or other natural organisms without causing any pollution. The waste materials which are degraded by natural factors like microbes for example - bacteria, fungi and a few more), and abiotic elements like temperature, UV, oxygen, etc. Biodegradable waste is used to produce biogas, compost, and energy manure. Common examples of biodegradable waste in municipal solid waste include food waste, green waste, and other biodegradable plastics.
A Non-Biodegradable material can be defined as a kind of substance which cannot be broken down by natural organisms and acts as a source of pollution. Non-Biodegradable waste can be separated and recycled for further use.
Non-biodegradable wastes that can be recycled and are known as recyclable waste and those which cannot be recycled are known as non-recyclable waste. Some examples of non-biodegradable waste are cans, metals, and plastic bottles etc.
Recycling is the process of converting waste materials into new materials and objects. Materials like plastic bottles, paper, glass, cans and containers can be recycled and reused. The food waste from households and farms can also be converted into fertilizers, biogas, slurries to feed animals.
