Causes of Waste Management

Waste Management

We can see and observe heaps and heaps of garbage lying along the streets while passing through highways. This is partly because open dumping is the most common method of disposing off the waste in India.

The trash heaps are usually left hospitable to the environment and therefore the elements. These seldom have a sparse covering and may often attract pests or vermin.

Sometimes, these dumps are subjected to open burning, which may release toxic fumes and smokes. Occasionally there have been instances where enough heat has been generated to trigger an Unconstrained Ignition. 

Sometimes, wastes are illegally dumped into rivers and canals that fill land depressions without proper consultations. These practices cause a ton of issues over the long haul. These can prompt the corruption of the soil quality to drain harmful synthetic substances into underground water sources. Therefore, to stop such scenarios, proper waste disposal policies should be adopted.


Waste Management Techniques

Garbage accretion has never been much of a concern in the past, but due to globalization and industrialization, there is a need for a more efficient waste management method. Following are some of the modus operandi that are used today.

Landfill

In this process, the waste that can't be reused or recycled are separated out and spread as a skinny layer in low-lying areas across a city. A blanket of soil is added after each layer of trash. However, once this process is complete, the piece of land is said unfit for construction of buildings for the subsequent 20 years. All things considered, it can be utilized as a jungle gym or a recreation centre.

Incineration

Incineration is the process of controlled combustion of garbage to scale back it to incombustible matter like ash and waste gas. The fumes released from this process might be harmful and toxic, subsequently, are treated prior to being liberated into the environment. This process reduces the volume of waste by 90 per cent and is considered one of the most hygienic means of waste disposal. In some cases, the heat liberated is employed to supply electricity. However, some consider this process, not environmentally friendly given the generation of greenhouse gases like CO2 and carbon monoxide gas. 

Waste Compaction

The waste materials like cans and plastic bottles are compacted into blocks and sent for recycling. This process quickens the oxidation of metals and decreases airspace need, subsequently making transit and positioning simple.

Biogas Generation

Biodegradable waste, such as food items, animal waste or organic industrial waste from food packaging industries are sent to biodegradation plants. In bio-degradation plants, they're converted to biogas by degradation with the assistance of bacteria, fungi, or other microbes. Here, organic matter is food for microorganisms. The breakdown can happen with oxygen (aerobically) or without oxygen (anaerobically). Biogas is created because of this cycle, which is utilized as fuel, and the buildup is utilized as fertilizer.

Composting

All organic materials decompose with time. Food scraps, yard squander, and so on, makes up a significant portion of the natural waste we toss each day. The process of composting starts with these organic wastes being buried under layers of soil and then left to decay under the action of microorganisms like bacteria and fungi.

This results in the formation of nutrient-rich manure. Additionally, this interaction guarantees that the nutrients are recharged in the dirt. Other than enhancing the dirt, composting the dirt additionally increases its water retention capacity. In agriculture, it's the simplest alternative to chemical fertilizers.

Vermicomposting

Vermicomposting is the way of utilizing worms for the debasement of organic matter to supplement rich manure. Worms consume and digest organic matter. The results of assimilation which are discharged out by the worms make the dirt supplement rich, consequently upgrading the development of microbes and other organisms. Additionally, it is definitely more compelling than the conventional method of treating the soil.


Causes of Waste Management

The causes of waste management are important to know from a tutorial perspective. If not for efficient waste management, the streets would be suffering from filth, lakes and rivers would become very toxic at all times. Human health would be severely affected if careful waste management practices didn't exist. Therefore, the main causes of waste management practices inherit play after environmental disasters especially oil spills. The primary purpose of waste management is to make sure that proper actions and activities are undertaken from the initial creation to final disposal. The obliviousness of the environment's predicament fundamentally adds to the making of waste management principle.

FAQs (Frequently Asked Questions)

1. How Important is Waste Management?

Ans: Waste management is a very integral part when it comes to keeping the environment clean and free from diseases. If waste is not managed properly, it will tend to decompose and spread different types of diseases. Management of waste is not only important for the health of human beings but also animals. Many deaths have taken place because of being negligible in waste management.

2. How Can Wastes Be Utilized?

Ans:  Wastes can be utilized by adopting the following modus operandi - 

  1. Landfill 

  2. Waste compaction 

  3. Biogas generation

  4. Vermicomposting.
