Question

Mark the statement that describes the eco-friendly disposal of municipal solid waste.
A. It should be burnt to completion.
B. It should be dumped in the open wasteland.
C. It should be dumped in sanitary landfills.
D. It should be sorted out into bio-degradable, non-biodegradable, and recycle wastes and treated separately.

Answer 1

Hint: Solid waste is garbage generated by either human or animal activities that are discarded as unnecessary and useless. Waste can be separated according to its composition, such as paper, plastic, glass, metal, and organic waste. To ensure environmental best practices, solid waste disposal should be formulated systematically. Metal, paper, glass, rags, certain types of plastic, and other materials can be retrieved, recycled, and reused. Biodegradable waste is composted, and recycling is encouraged whenever necessary. Hazardous waste can be discarded in a safe manner.

Complete step-by-step solution:

Eco-friendly materials and items are those that are not harmful to the environment. Municipal solid waste is defined as commercial and domestic waste generated in municipal or notified areas in either solid or semi-solid form, excluding industrial hazardous waste but including treated bio-medical waste.
Municipal authorities must establish and maintain storage facilities in such a way that they do not create unsanitary and hygienic conditions around them. Storage facilities or 'bins' must be designed to be 'user-friendly' for waste handling, transfer, and transportation. Bins for biodegradable wastes must be painted green, those for recyclable wastes must be painted white, and those for other wastes must be painted black.
Therefore, solid waste needs to be sorted out into biodegradable, non-biodegradable, and recycled wastes and treated separately because each of them has different responses to different disposal methods.
Land filling shall be confined to non-biodegradable, residual waste and certain other waste that can't be recycled or biologically processed. Solid waste problems are more prevalent in megacities, and the dangers take on new dimensions in coastal cities.
Within the permission given to them by relevant Acts and Rules, the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) have attempted to persuade local bodies to adopt appropriate measures for the treatment and removal of domestic wastewater and municipal solid waste.

Therefore, The correct option is D.

Note: Several non-biodegradable solid waste materials have been shown to pose significant environmental risks when released into the land, water, and atmosphere. Domestic and commercial solid wastes are major pollutants in India's coastal regions.
