Waste management:- A modern way!
The daily waste produced per person is 0.74 kg. It means millions of tons of trash are being made every day. This is quite apparent in a country with a total population of 140 crores. Thus, it leads to heavy problems of waste management in the country. Given the vast magnitude of waste generated by all of us, the need for urgent and creational intervention becomes equally important from an on-government purview.
They have their waste management methods – from simple separation and recycling to complex measures such as waste-to-energy strategies, landfill gas extraction, and scientific discard management among others. Working to eliminate waste from our landfills, such strategies also lend themselves to a more sustainable and resource-recovering mindset. The source segregation of waste is a primary step in waste management to recycle and treat the various materials part of waste. What are the ways that government use to manage these wastes? How viable are these strategies? This blog shall deal with the fundamental ways of waste management.
Ways of waste management
Landfills
The garbage here is laid in the form of thin layers of soil. This especially includes the non-degradable waste which cannot be recycled. Then another thin layer of soil is laid above it. When it appears brownish, it is allowed to be used for construction work or serve as a parks to the general public. This makes waste management feasible for authorities.
Vermicomposting
Here some special worms such as Eisenia fetida (commonly known as red wigglers) or Lumbricus rubellus, are in organic waste materials. They are used to convert the biodegradable wastes into manure for agriculture. For the practice, a bedding material is prepared for the worms made from shredded paper, cardboard or coconut coir mixed with moisture to create a little worm heaven. This organic waste is then mixed in with the bedding where worms can consume and digest it. The worms digest the waste and excrete it as a rich, dark, crumbly material called vermicast or worm castings. The vermicast is loaded with useful bacteria and essential nutrients, which provides a nice fertility to the soil. This helps the farmers to get a good harvest with nutrient-rich soil with efficient waste management.
Incineration
Incineration is a process of combustion of waste materials in a controlled manner. Here it can be polluting therefore the gases are treated before it is allowed to get into the air. Here the energy generated is used for the production of electricity. Typically incinerating simplicity gods is wasted materials, gotten into rooms where they are burnt containment cells that usually surpass 850°C (1562°F). A high-temperature treatment eliminates organic substances hence reducing garbage amount by ninety per cent. It is easy to manage this resulting ash whose make-up is mostly inorganic substance due to its smaller size, either through dumping alongside other less useful pieces that take up space or through adding onto structures. However, due to the production of greenhouse gases, it is sometimes not considered environmentally friendly.
Biogas generation
All the biodegradable waste materials are sent to biogas plants. Here with the action of bacteria and fungi, the wastes are converted into biogas. This can be used for supplying fuel for cooking or other purposes. It is indeed green energy and is a good substitute for non-renewable energy.
Recycling
You can recycle most of the domestic waste generated in your house. Similar industries also use many recycling techniques to save cost and energy. This allows the reuse of those materials which once called as waste. For instance, many companies are using their plastic waste to produce sculptures that can be used for decoration purposes.
Plasma gasification
It is a waste management technique that is used to convert waste into energy. The carbon-based materials are exposed to high temperatures and converted to syngas, a gas that can either be directly combusted or further refined into chemicals and higher-grade fuels. The non-organic part of the waste is converted to slag–cooled, tightly bound solid waste which can be used in construction as a raw material.
Benefits of using eco-friendly waste management mechanisms
Reduced pollution: –
It tends to reduce environmental pollution significantly. When the wastes rather than being burnt are used to generate energy, it becomes environment friendly.
Substitute to non-renewable energy:-
There are limited energy resources present on the earth. Therefore we require alternate forms of energy resources. The efficient waste management technique can generate enough energy that can be used for our daily needs. Thus it can act as an alternate energy source for us.
Increases employment opportunities:-
Recycling and reuse of wastes requires manpower. Therefore it created a tremendous amount of employment opportunities that ensured the income of many families.
Thus in a nutshell we shall conclude that the tons of waste that are being produced daily need an effective and eco-friendly way for its disposal. The materials that are taken from the environment need to be returned in a similar fashion.
