Biodegradable And Non-Biodegradable Substances

Edited By Irshad Anwar | Updated on Oct 22, 2024 03:31 PM IST

Biodegradable waste consists of waste like food scraps and paper and these are decomposed naturally on the other hand non-biodegradable waste is those kinds of waste which are not degraded easily and these are plastic metals and glass. These non-biodegradable wastes resist themselves and remain in the environment for a longer period. Waste materials management is one of the topics in Biology and they carry a weightage of 2-3% in NEET and 4-5% in CBSE and other Paramedical Exams.

Biodegradable Waste

Any organic material in the garbage that may be broken down by microorganisms and other living things through composting, aerobic digestion, anaerobic digestion, or similar processes into carbon dioxide, water, methane, or simple organic molecules is considered biodegradable waste. Some basic points about biodegradable waste are discussed below:

  • Biodegradable waste helps in the reduction of environmental pollution when they are decomposed properly.

  • This waste also contributes to the production of compounds which are used to increase soil fertility.

  • Decomposition of biodegradable waste occurs faster when compared to non-biodegradable waste.

  • Biodegradable waste is also used to generate biogas which is a renewable source of energy during decomposition.

  • Biodegradable waste also helps in breaking down the harmful toxins which are present in the environment during the process of decomposition.

  • They play a very important role in fixing the natural nutrient cycle and enhancing plant growth and development.

Sources Of Biodegradable Waste

Biodegradable waste is collected from different natural and organic sources that are decomposed with time. These are the sources which are also important for restoring the nutrients to the ecosystem and they need to be managed sustainably. Some of the major sources of biodegradable waste are discussed below:

  • Agriculture waste consists of crop residue animal manure and some of the by-products from farming activities.

  • Food waste which is normally collected from households and restaurants consists of leftover spoiled food and also some kind of kitchen wastage which works as a natural fertilizer.

  • Garden waste consists of grass clippings, leaves, branches and other plant materials which can be easily decomposed by microorganisms.

  • The waste is also collected from would clips and untreated Timber from the construction and carpentry sites.

Non-biodegradable Waste

A chemical that cannot break down or dissolve spontaneously and causes pollution is referred to as non-biodegradable waste. Some of the basic facts about non-biodegradable waste are discussed below:

  • They may stay on this planet for a very long time without degrading, which would pose a serious threat to the ecology.

  • The incapacity of nature to break down things that humans generate is one of the negative repercussions of current technological progress.

  • Nonbiodegradable garbage can persist for hundreds of years and seriously harm the environment.

  • They may be seen lying around as litter in parks, rivers, or streams.

  • The ecology has suffered as a result of the accumulation of waste products, including plastic.

  • As a result, there are now mountains of non-biodegradable rubbish in many parts of large towns.

Non-biodegradable Waste Management

Proper management of this Non-Biodegradable waste is very important. Some important points are discussed below:

  • Non-biodegradable garbage destroys the environment and causes harm to people, animals, and plants.

  • Non-biodegradable garbage must be handled with care by the government and by every individual.

  • It can only be accomplished by recycling, reusing, and reducing.

  • Non-biodegradable wastes must be disposed of in a landfill or, if feasible, recycled because they are not eco-friendly.

  • To create new plastic bags, for instance, old ones can be pelletized.

Difference between Biodegradable and Non-Biodegradable Waste

Major differences between Biodegradable and nob- biodegradable waste are discussed below in the table:

Biodegradable waste

Non-biodegradable waste

  • Consist of organic materials like food paper and plant materials

  • Consist of synthetic materials like plastic metal and glass

  • Breaks down easily by microorganisms present for decomposition

  • The decomposition stuff and the materials take a very long time to be decomposed.

  • Cannot be broken down by microorganisms present naturally.

  • Has no harmful impact on the environment and also increases soil fertility when composed properly.

  • It has a very bad impact on the environment and leads to pollution and damage to the ecosystem.

  • Biodegradable waste also helps in producing biogas during decomposition which is a renewable source of energy.

  • It cannot be converted into a renewable source of energy directly.

  • Biodegradable waste can be decomposed or used as an organic fertilizer for farming or agriculture.

  • Non-biodegradable waste requires recycling or disposal in the landfills.


Treatments for the Biodegradable And Non-Biodegradable Substances

Whether biodegradable or not, they endanger human life, injure other living things, and degrade the environment. Therefore, garbage must be properly treated. Everybody, including the government, must do this.

The three R—Recycle, Reuse, and Reduce—are the most straightforward actions that anyone can take to contribute. Energy and other resources can both be saved in this way. The separation of non-biodegradable from biodegradable at home and separate disposal of each is a further step.

Frequently Asked Questions (FAQs)

1. How to identify biodegradable waste?

One of the greatest ways to understand how biodegradable garbage works is through the example of paper. When you throw a bunch of paper in a deserted area with soil and grass and then return to the area later, you won't be able to find the papers you placed there weeks before. You consequently discover soil or muck. Biodegradable trash includes paper. Decomposing describes the process through which the earth takes up the trash.

2. How to reduce biodegradable waste?

Microbial processes do not break down non-biodegradable materials. The environment may be harmed by their disposal in the soil, burning, or dumping into bodies of water. Recycling them from landfills and marine depositions is therefore the best way to reduce their deposition. In other words, without subjecting them to any chemical or physical processes, we can repurpose them. Useful alternatives include using cloth carry bags and avoiding the disposal of non-biodegradable materials.

3. What is the difference between biodegradable and non biodegradable substances?

On a daily basis, we utilise a lot of materials, some of which directly produce waste, while others do so as a result of the normal wear and tear of domestic, industrial, and other commodities. Vegetables, fruit, and other waste products that originate from food waste are biodegradable resources. Both biodegradable and non-biodegradable elements can be found in other household garbage. Biodegradable items include wood, paper, and clothing composed of natural fibers. Non-biodegradable items include polythene bags, razors, and other items. Understanding how the degradation process works will help you distinguish between the two materials since degradable things are impacted by microbial action during the decomposition process, whilst non-degradable materials are not.

4. How does non-biodegradable waste affect the environment?

After some time, non-biodegradable materials release a lot of toxic gasses and chemicals, which have a very severe impact on plant life and animal habitat. These materials are resistant to the healthy breakdown of natural components found in nature and take millions of years to degrade. Plastics and synthetic fibers like nylon, polyester, batteries, glass, etc. are some examples of non-biodegradable materials. They are more frequently utilised than their biodegradable equivalents because of how convenient they are. It seriously disturbs the ecosystem's balance because of its slow decomposition.

5. How are biodegradable substances useful?

Biodegradableerials are kind to the environment. They support the environment in a number of ways. They easily dissolve when exposed to natural elements like fire, water, earth, and air and are good for the ecosystem's equilibrium. Biodegradable materials are capable of being used in more cost-effective and beneficial ways because of the efficient process that breaks down their structure in a microbe. Food, plants, animals, paper, wood, vegetables, fruits, and many other things are examples of biodegradable materials. These materials support the ecosystem's natural cycle, are simple to recycle, and don't harm the environment.
