Essay on Waste Management: Effectively managing the segregation of waste and following the activities until their final disposal is termed waste management. The biggest concern about waste management technologies is to clear off the waste generated from every household. The process consists of several stages like waste collection, transportation and finally, disposal. Waste management is based on the type of waste, the level of harm it causes, and the waste’s infection quotient.
Essay on Waste Management 500 Words in English
Below we have provided the Waste Management Essay in English, suitable for class 6, 7, 8, 9 & 10.
The whole method of managing, treating, storing, shipping, reprocessing and disposing of chemical, human and environmental waste is known as waste management. Waste management is a global subject, but its implications are more evident in developing nations. With the growth in population, sub-urbanization, social and economic growth, marketing, etc., solid waste management that is a relatively colossal activity is becoming more complex. Official insubstantiality, economic constraints and a public approach to waste management have made the issue worse.
Waste management is essential for maintaining living beings’ well being and also for building a healthy atmosphere for the generations to come. It helps to minimize pollution and can substantially reduce emissions of gases such as carbon dioxide and methane from waste by adapting to effective waste management techniques. It also helps in avoiding infectious diseases.
Methods for Waste Management
- Incineration – Under this waste management system, public solid waste is buried for turning it into oil, dust, steam, ash and gases. It eliminates solid waste by about 31 per cent of the total amount.
- Landfills – Disposal of garbage and waste within landfills is one of the most common waste management methods. Under this process, problems such as garbage hazards and odour are eradicated. The waste is deposited at landfill sites.
- Composting – Composting is a method of biodegradation of waste management in which the agricultural waste, i.e., flora leftovers and pantry waste, is converted into flora feed. This method is used for organic-farming that often improves soil fertility.
- Recycling – In this waste management system, the waste products are reprocessed for reuse. The waste stuff is reprocessed for extracting resources or converting it into energy such as heat, electricity, coal.
- Anaerobic Digestion – Anaerobic digestion is the waste management method which with the aid of organic procedures degrades biological materials. It uses the surroundings free of germs and oxygen for decay. Composting requires air to aid in bacteria growth.
- Waste Minimization – This is the easiest way to handle waste and helps to generate less waste. Anyone can achieve declining waste by reducing waste creation and reprocessing and recycling of old resources. It is important to use sustainable products and to decrease the use of paper, plastics etc. The public input has a direct impact on the waste management system.
- Waste to Energy Conversion – Under this waste management process, non-biodegradable wastage is converted into energy sources such as coal, heat, or electricity. Both of these are sources of renewable energy as the non-biodegradable waste could be used repeatedly to produce electricity.
- Pyrolysis and Gasification – These two waste management methods are used to decompose the remaining organic materials by exposing them to a limited amount of oxygen and elevating the temperature. Oxygen is not used in the pyrolysis procedure and, only a minimal amount of oxygen is used in the gasification process.
Waste Management System in India
Waste management in India relies on sustainable growth, polluter speed and precautionary standards. These principles allow the regions and business foundations to behave responsibly and conscientiously on Earth by restoring the ecological balance, their actions in some way upset it. The expansion of waste generation as a side-effect of financial development has prompted numerous subordinate enactments to direct the mode of transfer and was rendered under the Environment Protection Act (EPA) enacted in the year 1986.
When we see waste generation in the context of India, according to Environment Ministry of the country, “62 million tonnes of waste is generated annually in the country at present, out of which 5.6 million tonnes is plastic waste, 0.17 million tonnes is biomedical waste, hazardous waste generation is 7.90 million tonnes per annum, and 15 lakh tonnes is e-waste. Only about 75-80 per cent of the municipal waste gets collected, and only 22-28 per cent of this waste is processed and treated.” (source: moef.gov.in, Minister of Environment, India)
The Indian Government has also laid down some rules regarding the management of solid waste and frequently keeps checking on it’s proper implementation. The recent rules of 2016 have rules on segregation of waste at source, collection and disposal of sanitary waste, waste processing and treatment and promoting conversion of waste into energy as well as the use of compost.
