- Our morning starts by cutting open the milk pouch.
- We pour the milk into the boiling pot and trash the plastic pouch.
- We peel the veggies for cooking and trash the peels.
- We receive home deliveries of the products we buy from online or offline stores and throw the packaging into the trash can.
- These are some examples of domestic wastes.
- Similarly, there are industrial wastes that account for a larger share.
- Every day we produce as much waste product as we consume.
- Waste materials are growing all over the world, and every year billions of tonnes of waste are generated.
- These wastes are the result of domestic, business, and industrial activities throughout the day.
- Incineration and landfill cause greenhouse gas emissions of carbon dioxide and methane.
- In a country like the USA, the waste produced every year amounts to approximately 250 million tonnes.
- The volume of waste in India is projected to rise from the present 62 million tonnes to 150 million tonnes by 2030.
What Is Difference Between Biodegradable And Nonbiodegradable?
- The accumulation of waste causes large-scale pollution of land and water and increases the cost that we have to pay for hampering the environment in this manner.
- Waste materials can be classified as biodegradable and non-biodegradable.
- Biodegradable wastes are those waste materials that are degraded by abiotic elements like oxygen, temperature, UV, etc., and also natural species like bacteria, fungi, and microbes.
- Food materials, kitchen wastes, and paper bags are some examples.
What Is Non Biodegradable Waste With Examples?
- Non-biodegradable waste is defined as a substance that cannot be decomposed or dissolved naturally and acts as a source of pollution.
- They may remain on this planet for many years without any degradation, thereby posing a critical threat to the environment.
- Non-biodegradable waste examples include- plastics, metal, aluminium cans, tyres, pains, toxic chemicals, toxic chemicals, polystyrene, etc.
Non Biodegradable Definition And Examples
- A notorious example is plastic that is used in everything-from cola bottles to pencil boxes.
- Other examples are tin cans, chemicals for agricultural or industrial purposes, and some metals.
- They can cause diseases like cancer and are the major sources of air, soil, and water pollution.
- Inorganic wastes are also non-biodegradable.
Differences Between Biodegradable And Non Biodegradable Pollutants
|S.NO.||Biodegradable Waste||Nonbiodegradable Waste|
|1||Degradation process is rapid||Degradation process is slow|
|2||It is decomposed and degraded by microbes||It cannot be decomposed|
|3||It disappears in a short time.||It often accumulates|
|4||It becomes part of biogeochemical cycle||It does not become part of the cycle. Instead turns toxic|
|5||Useful. Can be used to produce biogas, manure, etc.||It can be separated and recycled, but the process is expensive.|
- Non-biodegradable wastes can be divided into two categories: Those that can be recycled are called “Recyclable Waste” and those that cannot be recycled are called “Non-Recyclable Waste”.
- Paper is an example of recyclable waste.
Disadvantages Of Non Biodegradable Waste
- One of the side effects of modern technological advancements is the inability of nature to decompose substances that humans create.
- For example, the polythene used in shopping bags is non-biodegradable, meaning it does not break down naturally in landfills.
- The non-biodegradable waste can last for hundreds of years and cause severe environmental problems.
- They can sit as litter in forests, parks, rivers, or streams.
- The piling of throwaway plastic and other materials has taken a toll on the ecosystem.
- It has led to heaps of non-biodegradable waste forming in many areas of major cities.
- Non-biodegradable single-use plastic is one of the biggest sources of pollution in the 21st century.
- They are used in a variety of items-from food wrappers to plastic bags and account for 40 % of the plastic produced each year.
- These remain in the environment for many years because they cannot be broken down by micro-organisms.
- They block drains and also harm animals.
- Animals can choke on plastic while eating.
- Plastics release harmful gases upon heating or burning and can also contaminate foodstuffs.
Non-Biodegradable Waste Management In India
- Non-biodegradable waste harms human, animal, and plant life, and also ruin the environment.
- It is the responsibility of both the government and also every citizen to treat non-biodegradable waste with proper care.
- And the only way to do it is to Recycle, Reuse, and Reduce.
- Since non-biodegradable wastes are not friendly to the ecosystem, they need to be removed to a landfill, or if it is possible, recycled.
- For example, old plastic bags can be pelleted to make new ones.
- Scientists have incorporated elasticity and long-lasting qualities just the same as plastics to some biodegradable materials that give the same benefits as plastic to the users and also get decomposed very easily.
- The palm oil industry generates waste.
- It is a good idea to recycle this waste into biodegradable plastic film and used it in the food packaging industry.
- Hemicellulose is a naturally occurring biopolymer that goes into the manufacturing of renewable materials such as protein and polysaccharides.
- Due to its biodegradability and low cost, it can replace non-biodegradable, petroleum-based polymers, or plastics.
Polymer Waste Disposal
- The polymer waste consisting of plastic can be disposed of through the process of pyrolysis.
- The process involves the polymer waste being heated in the presence of a suitable catalyst to a temperature of 400-600°C in an anaerobic environment.
- A volatile matter comes out of the waste, which condenses to give pyrolysis oil.
- This oil, after purification, can be reused for heating purposes, so this process is self-sustainable.
Construction Waste Management
- Construction and Demolition (C & D) wastes are generated that require separate handling and disposal mechanisms.
- This waste is collected at earmarked sites identified by the municipal corporations and transported to the designated recycling and waste processing facilities.
- In these processing facilities, aggregates, bricks, kerbstones, paver blocks, sand, and soil are produced out of the C & D waste.
- These are later reused in infrastructure projects.
- Hence, fresh natural resources need to be sorted while doing construction waste management in India.
Sustainable Solid Waste Processing
- Indiscriminate dumping of garbage without treatment requires a huge landfill area each year.
- So, in today’s context, scientific solid waste management has become necessary.
- The plasma arc gasification process is an eco-friendly way to reduce the large volume of waste by up to 95%.
- This process uses electricity to generate a high temperature of over 3000 °C that converts the waste into syngas.
- CSIR has developed a Municipal Solid Waste Processing Facility that has a mechanised segregation system.
- It segregates solid waste into biodegradable waste (foods, fruits, grass, vegetables, etc.), metallic waste (like metal body or container), inert (glass, stones, etc.), and non-biodegradable (bottles, plastics, packaging material, pouches, etc.).
Waste Collection And Disposal
- The scientific collection and disposal of non-biodegradable wastes like batteries and glass are gradually being practiced in different parts of the country.
- Municipal workers visit commercial establishments and households to collect waste.
- The waste collected in bins is segregated into biodegradable, domestic hazardous, and non-biodegradable.
- Such waste is classified and sorted as per the types of plastic and other materials.
- They are then sent to recycling units as per norms prescribed under the Solid Waste Management Rules, 2016.
- Waste packets are brought to the material collection facility for further sorting as per the various classifications of the non-biodegradable waste.
- Green volunteers are selected from local N.G.Os and are trained to sort waste as per the requirements of the recycling industry.
- A green protocol committee has been formed in each municipality to coordinate the various initiatives.
- Its task is to ensure that the wards under it turn plastic-free.
- Local bodies are hoping that the expenses incurred for the handling of waste could be reduced as the scientific classification and sorting for the recycling industry would bring in revenue for stakeholders.
- The non-biodegradable wastes that we generate results in numerous environmental and health hazards.
- We should all do our part to keep our planet clean.
- We hope that this article will enlighten the readers about this hidden danger and encourage them to fight it.
