biodegradable materials non-biodegradable materials
Answers
Answer:
Biodegradable - Refers to the materials or objects which can get easily decomposed in nature by organisms like bacteria. ... Non - Biodegradable Waste is the kind of waste that cannot be decomposed by the biological processes. Most of the inorganic, plastic and artificial waste are non-biodegradable
Explanation:
Please mark me as brainliest and follow for points
We produce a lot of wastes on a daily routine and throw them away or discard them. These substances include kitchen waste like vegetables and fruit peels, empty cartons, used tea leaves, and so many expendable items like juices, plastic bags, paper, old clothes, old footwear etc. Many of these materials like paper, vegetable and fruit peels can be easily broken down by the action of bacteria or other decomposers. Such substances which can be easily broken down by the action of bacteria are named as biodegradable substances. Other substances or material like plastics, metallic cans and pesticides which cannot be broken down easily by biological processes are named as non-biodegradable substances.
Biodegradable and Non Biodegradable
Technology has enhanced the quality of life and given birth to an innovative form of life. This has an erratic impact on the environment and other lives on the earth. For example, water bottles made of plastic, which is convenient to use and carry but its disposal is a test for nature.
There are tons of waste materials which are degradable and non-degradable. Therefore, classification and proper disposal of wastes are necessary. Waste materials can be categorized as biodegradable and non-biodegradable. Risk and threats associated with waste disposals can be easily evaded by the knowledge on forms of wastes.

What is the Meaning of Biodegradable?
Definition
A biodegradable material or substance can be defined as a material which can be decomposed easily by bacteria or any other natural organisms and not being the part of pollution.
Biodegradable wastes are the waste materials which are and can be easily degraded by natural factors like microbes (e.g. bacteria, fungi and few other), abiotic components like temperature, UV, oxygen, etc. few examples of such wastes are kitchen wastes, food materials, and other natural wastes. Microorganisms and other abiotic elements worktogether break down complex substances into simple organic matters which finally suspend and disappear into the soil. The whole process is natural which can be fast or slow. So, the environmental issues and risks caused by biodegradable wastes are very low.
Examples of Biodegradable
But the giant dumping of waste can increase some threats to life sooner or later. To prevent this, some people practice known as composting. In composting, the biodegradable wastes are dumped into a big pit and covered for a time period. During this the action of microbes, they will decompose and will be used as compost for cultivation purpose. This will reduce the quantity of waste at landfills.
What is Biodegradable Waste?
Biodegradable waste is a form of waste, originating naturally from plant or animal sources, which may be degraded by other living organisms.
Biodegradable waste can be usually found in municipal solid waste such as green waste, food waste, paper waste, and biodegradable plastics. Some of the sources contain human waste, sewage, slaughterhouse waste etc.

Definition
Waste which cannot be decomposed or degrade by the biological process is known as “Non-biodegradable wastes”. Most of them include inorganic waste is non-biodegradable.
What Does Non-biodegradable Mean?
A Non-Biodegradable material can be defined as a type of material which cannot be broken down by natural organisms and serve as a source of pollution.
Unlike biodegradable wastes, non-biodegradable wastes cannot be easily taken care of. Non-biodegradable wastes are those which cannot be decomposed or degraded by natural agents. They remain on earth for thousands of years without any degradation or decomposition. Therefore, the threat caused by them is also more dangerous. An example is the plastic which is usually used in almost every area. To give these plastics a long-lasting outcome, better quality plastics are being used. This made them more temperature resilient and tougher even after the use. Other cases are cans, metals, and chemicals for agricultural and industrial uses. They are the chief causes of air, water and soil pollution and diseases like cancer.
Since non-biodegradable wastes are not at all Eco-friendly, they need to be replaced or substituted. As a part of the growth of alternatives, scientists have brought forward many innovative ideas like biodegradable plastics, etc. They combined some biodegradable materials with plastics and made them easily and speedily degradable. But this is quite a costly procedure. Non-biodegradable wastes which can be recycled and can be used again are known as “Recyclable waste” and those which cannot be used again are known as “Non-recyclable
