A biodegradable material can be defined as a material which can be decomposed by b bacteria or other natural organisms and not be adding to pollution.
Biodegradable wastes are such waste materials which are and can be degraded by natural factors like microbes (e.g. bacteria, fungi and few more), abiotic elements like temperature, UV, oxygen, etc. Some examples of such wastes are food materials, kitchen wastes, and other natural wastes. Microorganisms and other abiotic factors together break down complex substances into simpler organic matters which eventually suspend and fade into the soil. The whole process is natural which can be rapid or slow. Therefore the environmental issues and risks caused by biodegradable wastes are low.
Examples
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.
But the huge dumping of waste can raise some threats to life sooner or later. To avoid this, some people practice composting. In composting, the biodegradable wastes are dumped into a pit and covered for a period. Due to the action of microbes, they will decompose and will be used as manure for cultivation purpose. This will reduce the amount of waste at landfills.

The waste materials that can be broken down or decomposed into simple substances in nature, by the action of microorganisms, such as bacteria, in due course of time are called biodegradable waste materials.
The biodegradable waste decomposes naturally and becomes harmless to humans, other organisms and environment after some time. For example, dead plants and animals (including bones), animal excreta (cattle dung, urine), leather goods, tea leaves, wool, paper, plant parts, hay and wood, cotton clothes, cardboard, seeds, grains and compost (manure made from decayed plants and vegetable stuff) are all biodegradable materials.
Non-Biodegradable Waste Materials:
The waste materials that cannot be decomposed to simple, non-poisonous substances in the nature are called non-biodegradable waste materials. For example, plastic, polythene bags, synthetic fibres, glass objects, metal articles like aluminium cans, silver foils, certain detergents, fertilizers, pesticides like DDT and radioactive wastes. For instance, DDT is a non-biodegradable waste.
It cannot be degraded or decomposed into simple compounds by the action of microorganisms in nature. Thus, it gets accumulated in the environment and harms humans, other animals, and even vegetables and plants. Thus, DDT has been banned for use in most of the countries.
Recycling of Biodegradable Waste:
Some of the biodegradable wastes can be recycled to restore our natural resources and ecological balance. We may again use the products of recycled materials for our day-to-day activities.
Prevention and Control of Soil Pollution:
i. Effluents from industries and factories should not be allowed to enter the soil indiscriminately.
ii. Drainage system should be so developed that the polluted water does not get mixed up with the soil.
iii. Proper toilet facilities should be provided to all and awareness should be created about the harmful effects of defecation in open places.
iv. Fertilizers, pesticides and insecticides should be used judiciously so that excess chemicals are not washed into the soil.
v. Safe methods of disposal of domestic, agricultural and industrial solid wastes should be adopted.
