Urban Waste Disposal| Class 12 Geography Notes

Urban Waste Disposal is a subpart of the Class 12 Geography Chapter 9 which is Perspective on Selected Issues and Problems. The subpart of Urban Waste Disposal discusses the type of waste and its treatment processes for a safe environment. The urban areas are the major hub of the development of a country but there are so many problems related to the increased amount of waste. So it is important to process those waste materials. Urban waste is a type of waste which are collected from different cities and towns in solid or liquid forms. These wastes can be divided further as hazardous and non-hazardous.

In this article, we are going to discuss Class 12 Geography Notes Chapter 9 Urban Waste Disposal.

What Are The Urban Waste?

Urban waste generally includes household, industrial, and public facilities wastes that are produced as rubbish in different cities and towns. We can consider solid, plastic, metal, and paper as the waste. It is really important to dispose of and recycle urban waste to decrease the different types of pollution, maintain hygiene, and make our lives more sustainable.

Methods Of The Urban Waste Disposal

There are four major processes of the Urban Waste Disposal which are majorly generated from the residential and industrial areas. Let us discuss.

Incineration Disposal

Incineration is a well-known process of the Urban Waste Disposal. It is the process of generating the energy from the urban wastes. The process is able to reduce the quantity of the waste by around 70 % with 90 % volume. But the problem is, that this process involves the process of burning that produces ash and greenhouse gases.

Composting Disposal

Composting is a process to reduce the waste volume by killing the pathogens present in it. The process reduces the amount of leachate generation and makes it a nonharmful material. We have to remember that the process of composting is only applicable for the organic waste only.

Construction and Demolition Waste Disposal

Hard and Concrete wastes are the major source of urban waste. This type of solid waste is continuously produced in urban locations due to construction works. This type of waste is majorly deposited in landfills and needs to manage these wastes for a sustainable environment.

Ceramic Waste Disposal

Ceramic wastes are no-recyclable in nature and majorly they are sold. These types of waste materials create so many problems in the landfills. It would be really helpful if these types of wastages could be recycled to the new products. These new products can be reused as the materials for the different construction projects.

Effect Of The Urban Waste Disposal

There are so many effects of the Urban Waste Disposal as mentioned below.

• Bad and inefficient waste management systems can affect our health due to the different unhygienic conditions.
• Urban waste contains so many disease factors like blood infection, respiratory problems, reproductive problems, and skin problems.
• These types of wastes cause so much pollution like water, air, and soil.
• The harmful chemicals affect the air, soil, and water. They contaminate this natural substance and make them also harmful to lives.
• The waste materials also contribute to the global climate change.
