​

Answer 1

Answer:

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.

Unlike biodegradable wastes, non-biodegradable cannot be easily handled. Non-biodegradable wastes are those who cannot be decomposed or dissolved by natural agents. They remain on earth for thousands of years without any degradation. Hence the threat caused by them is also more critical. A notable example is the plastics which are a commonly used material in almost every field. To give these plastics a long lasting effect, improved quality plastics are being put to use. This made them more temperature resistant and more durable even after use. Other examples are cans, metals, and chemicals for agricultural and industrial purposes. They are the main causes of air, water and soil pollution and diseases like cancer.

Since non-biodegradable wastes are not Eco-friendly, they need to be replaced. As a part of a development of alternatives, scientists have brought forward many ides like biodegradable plastics, etc. They incorporated some biodegradable materials with plastics and made them easily and rapidly degradable. But this is quite an expensive procedure.

Answer 2

Answer:

Non-biodegradable substances are those that do not degrade easily. These terms itself defines the ability of the substances which are degradable or not. rubber, plastic, chemicals, paint plastic falls under the category of the non-biodegradable items.It is usually seen that non-biodegradable substances are synthesized and does not occur naturally, hence their degradation is also not possible.The rate of decomposition is slow.As their degradation rate is slow and the separation and recycling are not easy and expensive too.They are harmful to the environment.But as these are readily available, convenient to use, and are of low cost, the non-biodegradable substances are more often used. But instead of returning to the environment, they become solid waste which cannot be broken down and become hazardous to the health and the environment.
