Explain the Waste management system.
Waste Management
WASTE MANAGEMENT:
It is the process by which waste that is marked to be discarded is treated in a manner to make a recycled product out of it. This indicates more about how waste can serve better and be something like a valuable asset. In the 21st century, the world needs waste management facilities. It is a non-compromisable activity that should be practiced in each and every household.
“Waste management is defined as the necessary activities and steps that are taken to control waste disposal from the original state to its final demolition.”
There is a total of eight major groups of waste management methods, which are further divided into subcategories.
Among the many methods, let’s have a quick discussion about the necessary and most useful ones:
Landfills
As we all know that soil plays a major role in the decomposition of organic matter. Thus, when we dump garbage, the chance of decomposition is increased automatically. Through this particular practice, waste disposal is done only on one particular land. Finding Landfills is not so difficult. Almost all developing countries have these in their cities.
But with time, the method is becoming limited. This is happening due to a Lack of space, and as we know, Landfills require space. Also, some chemicals, methane, are used on these landfills to reduce odor. Too much use of those ads causes contamination problems. While on the one hand, Landfills are managing waste disposal, on the other hand, it is harming the environment by contributing to rising air and water pollution.
Combustion
Combustion is also known as incineration, is the method by which solid wastes from municipalities are burned. Burning is done at a specific high temperature, which converts the waste into ashes and gaseous residues. This method works on a large scale, and it can bring down large quantities of waste by almost 20 to 30 percent of the original volume.
Incineration is the solution to the disadvantages that the landfill offers.
Recovery and Recycling
This is one of the most efficient and useful methods that is stressed nowadays. Recovery and recycling is the process in which there is a selection of materials from the discarded list and, with the execution of certain processes, they are made ready for use again. In particular, these are made into resources that can serve as some type of usable heat, electricity/fuel.
Recycling is mainly defined as the process of converting damaged/waste garbage products. It is an essential part of the three R’s: Reduce, Reuse, and Recycle. This reduces so many extra processes that can involve pollution rise. Thus, ultimately saving the environment in all respects.
