Waste management (or waste disposal) refers to the methods and activities involved in handling garbage from its generation to its final disposal. This includes waste collection, transportation, treatment, and disposal, as well as the regulation and management of the waste management process, including any laws, technologies, or economic measures related to waste. This article discusses how waste materials must be handled to ensure the safety of the public.
What is Waste?
The term "waste" refers to any item that is no longer useful and requires disposal. Essentially, waste is unwanted material that now needs to be discarded and sent for disposal. This undesirable material can be a by-product generated in any chemical process, such as fly ash from a furnace. It can also be a product that is now no longer useful owing to its age or other factors, like broken toys and devices.
Types of Waste
Regardless of the form and origin of the waste material in question, it can be broadly classified into one of two forms. These are:
Classification of waste
Biodegradable waste refers to any waste material or product that can be naturally broken down into smaller components over time by the action of water, air, sun rays, microorganisms, and other factors. This process involves the decomposition of organic matter into smaller pieces, which are then broken down into the soil by microorganisms, ultimately nourishing the soil. Common examples of biodegradable waste include kitchen waste such as leftover food, fruit or vegetable peel, animal waste, crop residues, and so on.
