Waste Management: Types, Challenges and Smart Solutions in India.

Waste management has a negative environmental impact and is one of India's biggest challenges. Every day, around 1.5 lakh metric tonnes of solid trash are produced by us. This covers not just trash and municipal waste but also many types of waste such as hazardous, plastic, e-waste, etc. To handle these diverse waste types, the Indian government has established several regulations and guidelines within the past ten years. To tackle the growing waste management problem effectively, we must comprehend these.

Waste Types.

There are many categories available here of waste.

1. Waste From Municipalities.

Municipal wastes are the wastes that are typically produced by residential and business operations. Wastes from demolition and construction projects are not included in them. Such trash pollutes water bodies when they are dumped in the open. Because these pollutants attract vector-borne diseases, public health is also at risk. Rising urbanization and changing lifestyles have resulted in a noticeable increase in municipal solid trash. 

Approximately 62 million tons of municipal solid trash are produced annually in urban India. Be aware that some plastic garbage is also produced by municipal rubbish.

2. Plastic Waste.

"plastic waste" refers to the general accumulation of plastic objects in the environment. Plastics can take many various forms, but the most common ones are single-use items like straws, bottles, bags, and so on. These plastics are known to interfere with the lives of all living things on Earth because they are not biodegradable. Uncollected plastic debris on land has clogged drains, resulting in various diseases transmitted through water.

3. Electronic Waste.

Electronic waste, sometimes known as e-waste, refers to discarded electrical and electronic products, such as household appliances, audio and video equipment, computers and their accessories, and so on. Toxic metals found in these items include chromium, lead, cadmium, and beryllium, to mention a few. When e-waste is recycled or disposed of using outdated techniques, like tossing it in the trash, it usually turns dangerous. When these hazardous substances are in the environment, they can seriously harm people's health.

4. Biomedical Waste Products.

Wastes generated during the treatment or immunization of humans or animals in a medical or research laboratory are referred to as biomedical or hospital wastes. This kind of garbage typically consists of bandages, used medications, syringes, etc. Toxins released by these biomedical wastes have the potential to seriously harm both marine and terrestrial ecosystems. According to a recent estimate, by 2022, India is expected to produce 775.5 tonnes of medical waste.

5. Radioactive Waste.

One category of waste that includes radioactive components is radioactive waste. The primary sources of these radioactive elements are nuclear power plants and mining operations. This type of garbage is known to release radiation that disturbs the environment. Such radiation can cause sunburns, harm skin cells, harm the eyes, and have long-term consequences like cancer and tumours. 

It has been observed that the intestinal lining, bone marrow, embryos, and fetuses are more vulnerable to radiation. A study indicates that India produces about 4 tonnes of radioactive waste annually.

Challenges in the Handling of Waste.

Waste management in India is a challenge. Even though there are still many obstacles to overcome, the informal sector is crucial in generating value from trash. 

1. 62 million tons of solid garbage are produced annually in urban areas with 377 million people, indicating rapid urbanization. All of the remaining material, however, ends up in landfills or untreated, with only 43 million tons being collected.

2. Projections indicate a significant increase in the generation of e-waste, which is another pressing issue.

3. Inadequate infrastructure for collecting waste, with only 21 million collectors nationwide compared to 700 million in China.

4. Only around 30% of waste is adequately sorted, which results in valuable items like plastic and aluminium ending up in landfills rather than being recycled. Sorting recyclable materials is another issue.

India's Solution for Waste Disposal.

1. The landfill.

This process involves separating and spreading the debris that cannot be recovered or repurposed into a thin layer in low-lying sections of a city. After every trash layer, there is a layer of dirt. However, after this process is finished, the site is declared unsuitable for construction for the following 20 years. Alternatively, it can just be used as a park or a playground.

2. Burning.

The process of carefully burning waste to turn it into non-combustible materials like ash and waste gas is known as incineration. This process is handled before being released into the environment because the exhaust gases it produces have the potential to be hazardous. This method is regarded as one of the cleanest ways to dispose of waste because it minimizes the amount of waste by 90%. Sometimes the heat produced is used to create electricity.

3. Compaction of Waste.

Cans and plastic containers are among the waste products that are compressed into blocks and delivered for reuse. This process prevents metals from oxidizing and reduces the amount of airspace required, which makes placement and transportation easier.

4. Production of Biogas (Green Energy).

Biodegradation plants receive eco-friendly garbage, such as food goods, pet waste, or naturally hazardous trash from the markets for food product packaging. They deteriorate in bio-degradation plants with the aid of bacteria, fungi, or other microorganisms to produce biogas. In this case, the input material feeds the microorganism. Both aerobically occurring with and without oxygen can lead to degradation. 

This process results in the generation of biogas, which is used as fuel and the deposit as manure.

5. Putting Up Compost.

The organic matter found in twigs and food waste can naturally decompose into a valuable fertilizer that can help plants and soil. This process is known as composting. By providing the ideal environment for bacteria, fungi, and other disintegrating creatures (including worms, sowbugs, and nematodes) to live in, composting merely speeds up the decomposition process. 

The broken-down material that, after the procedure, resembles rich garden soil. Compost is rich in nutrients and can be used in agriculture. It is frequently referred to as "black gold."

6. Gasification of Plasma.

Processing of municipal solid trash is included. Waste that contains carbon is transformed into basic chemicals and fuels. After the recyclables—such as metals—are filtered away, a consistent, dry feed is made. Next, a liquid slurry and the feed-extracting gas are heated by the plasma torches. Then, all contaminants are removed from the gas. The dangerous elements in waste are destroyed. It avoids the accumulation of waste in landfills and is a sustainable method of producing electricity.

7. Composting with vermiculture.

Vermicomposting is the technique of breaking down organic matter directly into manure that is high in nutrients by employing worms. The basic material is taken in and absorbed by worms. The worms' excretion of digested leftovers enriches the soil with nutrients, which promotes the growth of fungus and bacteria. Additionally, it is even more effective than traditional composting.

8. Reusing.

Recycling is the best way to manage waste if it can be collected effectively and consists of similar materials. Many affluent nations have policies that impose additional costs when buying recyclable materials. When the customer returns the material to a recycling facility or machine, they receive a reimbursement.

Conclusion.

Due to its enormous population and the amount of rubbish it produces annually (about 1.3 billion tons, or one-third of the world's total), India has substantial issues in the management of waste. Since just 5% of recycled material is now reused, India needs to develop its recycling sector. Protecting the environment and ensuring a sustainable future depend on finding solutions to these issues. In order to progress, India must make plans for the long-term management of trash and modify its approaches to reflect evolving lifestyles. For recycling to be more effective, garbage from homes and businesses needs to be segregated at the source.
