Classify solid waste and explain problem associated with it
Answers
Explanation:
There are several different ways of classifying solid waste. As you have seen, one way is to classify it by where it is generated. Another way is based on whether the waste is biodegradable or not.
Biodegradable solid wastes are those thatcan be broken down (decomposed) into their constituent elements by bacteria and other micro-organisms. Food waste, manures and waste from producing crops are the main biodegradable wastes. If the decomposition process takes place in the absence of air (anaerobically), methane gas can form. Methane is a powerful greenhouse gas and can explode if enough of it accumulates and an ignition source (such as an electrical spark) is present. The decomposition may also produce offensive and irritating smells.
Non-biodegradable (also sometimes called inorganic) solid wastes are those thatdo not decompose by microbial action. These wastes include plastic containers, scrap metal, food and drink cans and plastic bags.
Materials in solid wastes can also be classified as combustible or non-combustible, depending on whether they will burn or not.
