Waste management is essential in today’s society. Due to an increase in population, the generation of waste is getting doubled day by day. Moreover, the increase in waste is affecting the lives of many people.
For instance, people living in slums are very close to the waste disposal area. Therefore there are prone to various diseases. Hence, putting their lives in danger. In order to maintain a healthy life, proper hygiene and sanitation are necessary. Consequently, it is only possible with proper waste management.
The Meaning of Waste Management
Waste management is the managing of waste by disposal and recycling of it. Moreover, waste management needs proper techniques keeping in mind the environmental situations. For instance, there are various methods and techniques by which the waste is disposed of. Some of them are Landfills, Recycling, Composting, etc. Furthermore, these methods are much useful in disposing of the waste without causing any harm to the environment.
Methods for Waste Management
Recycling– Above all the most important method is the recycling of waste. This method does not need any resources. Therefore this is much useful in the management of waste. Recycling is the reusing of things that are scrapped of. Moreover, recycling is further converting waste into useful resources.
Landfills– Landfills is the most common method for waste management. The garbage gets buried in large pits in the ground and then covered by the layer of mud. As a result, the garbage gets decomposed inside the pits over the years. In conclusion, in this method elimination of the odor and area taken by the waste takes place.
Composting– Composting is the converting of organic waste into fertilizers. This method increases the fertility of the soil. As a result, it is helpful in more growth in plants. Furthermore it the useful conversion of waste management that is benefiting the environment.
Recycling is a method of procedure that includes the collection and breaking down of waste material to create something new out of it. The process was introduced sot that the non-biodegradable materials can be melted or break down to create something useful. After the effects of global warming and pollution have become known to men the process of recycling has become more important.
Why We Need Recycling?
We need recycling for many reasons. But most importantly, it will help us to save our planet. Besides, recycling saves the earth by facilitating the reprocess of paper which will save millions of trees.
Also, recycling saves a lot of energy because many things that we recycle can easily be converted into virgin materials. In addition, it saves a lot of resources too.
Moreover, recycling reduces the burden of the environment. As we save energy the number of greenhouse gases and oxides are produced in less quantity. Because most of the toxic gases are produced by factories.
In addition, recycling reduces the amount of waste, that takes years to decompose. Also, the recycled material can be sold. We use this recycled material for the manufacturing of many new products. So, ultimately recycling saves money.
How Can We Contribute to Recycling?
Almost everything that we use can be recycled whether it is household materials like paper, plastic, metal, glass, furniture, toys, artifacts, vehicles, etc. Besides, opt for things from the market that can easily be recycled. Also, try to use merchandise that is made up of recycled products.
In addition, sort your waste and dump your recyclable waste in the recycle bin so that the authorities can recycle it.
To Sum it up, recycling is a small step by humans to save the environment. But this small step is very effective in the long run. Also, before throwing away the waste we should check it to see if there is a recyclable product in it or not.
Advantages of Waste Management
There are various advantages of waste management. Some of them are below:
Decrease bad odor– Waste produces a lot of bad odor which is harmful to the environment. Moreover, Bad odor is responsible for various diseases in children. As a result, it hampers their growth. So waste management eliminates all these problems in an efficient way.
Reduces pollution– Waste is the major cause of environmental degradation. For instance, the waste from industries and households pollute our rivers. Therefore waste management is essential. So that the environment may not get polluted. Furthermore, it increases the hygiene of the city so that people may get a better environment to live in.
Reduces the production of waste -Recycling of the products helps in reducing waste. Furthermore, it generates new products which are again useful. Moreover, recycling reduces the use of new products. So the companies will decrease their production rate.
It generates employment– The waste management system needs workers. These workers can do various jobs from collecting to the disposing of waste. Therefore it creates opportunities for the people that do not have any job. Furthermore, this will help them in contributing to society.
Produces Energy– Many waste products can be further used to produce energy. For instance, some products can generate heat by burning. Furthermore, some organic products are useful in fertilizers. Therefore it can increase the fertility of the soil.
SEGREGATING WASTES :It is important to segregate waste on a daily wasteSegregating waste means separating biodegradable wastes from non biodegradable wastesBy this means, the wastes can be sorted and decomposed accordinglyThe simplest way we can contribute as an individual is having two waste bins at home – one for bio – degradable wastes another for non biodegradable wastes.
Wastes are materials that can be recycled on a regular basis. But because of our ignorance, a lot of waste gets dumped in landfills and pollution hits the planet finally. Only if we start creating awareness and take self responsibility we can clean our environment. For this, we have to learn to segregate our wastes on a daily basis. It is quite important to separate plastic wastes from bio degradable wastes. Plastic wastes should be totally separated from natural wastes. Plastic wastes do not decay like biodegradable wastes. Instead they take many years to breakdown even after which it is dangerous. On the other side, we cannot destroy plastic wastes by burning. Plastic wastes emit poisonous smokes when they are burnt. So, it is high time we avoid using synthetic materials. If not, we should try to segregate wastes and help in lessening the pollution level in our environment.
According to a recent study by the Centre for Science and Environment (CSE), nearly half of India’s waste-to-energy (WTE) plants, meant to convert non-biodegradable waste, are defunct.
Moreover, the existing plants are functioning at low capacity.Since 1987, 15 WTE plants have been set up across the country. However, seven of these plants have since shut down.The key reasons for closure are the plants’ inability to handle mixed solid waste and the high cost of electricity generated by them that renders it unattractive to power companies.MSW (municipal solid waste) in India has low calorific value and high moisture content.As most wastes sent to the WTE plants are unsegregated, they also have high inert content (inert materials like soil, sand, grit, etc).These wastes are not suitable for burning, and therefore to burn them, additional fuel is required which makes these plants expensive to run.Despite this, the NITI Aayog, as part of the Swachh Bharat Mission, envisages 800 Mega Watt from WTE plants by 2018-19, which is 10 times the capacity of all the existing WTE plants put together.It even proposes setting up a Waste-to-Energy Corporation of India, which would construct incineration plants through PPP models.
A waste-to-energy or energy-from-waste plant converts municipal and industrial solid waste into electricity and/or heat for industrial processing.The energy plant works by burning waste at high temperatures and using the heat to make steam. The steam then drives a turbine that creates electricity.Apart from producing electricity, burning waste also reduces the amount of material that would probably be buried in landfills. Burning MSW reduces the volume of waste by about 80%. Thereby offering a number of social and economic benefits that cannot easily be quantified.
The organizations that are working for the environment have created numerous methods that deal in waste management. The usage of new innovative technologies for handling and disposing of solid waste also helps in the direction of waste management.
