Solid waste disposal

Solid waste disposal

Solid waste includes any garbage, refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded materials including solid, liquid, semi-solid, or contained gaseous material, resulting from industrial, construction, commercial, mining and agricultural operations, and from community activities.

Management of Solid waste includes:



Ø Classification of waste


Ø Segregation & Sorting of waste


Ø Collection of waste


Ø Transportation of waste


Ø Storage of waste
Ø Treatment of waste
Ø Disposal of waste
The waste should be sorted and segregated at the source of generation in the below mentioned colour container or bins

Waste Prevention:

Waste prevention also called "Source Reduction" seeks to prevent waste from being generated. Waste prevention strategies include the use of less packaging, the design of products to last longer and the reuse of products and materials. Waste prevention helps reduce handling, treatment and disposal costs and ultimately reduces methane generation.

Recycling and composting:


Recycling is a process that involves collecting, reprocessing and / or recovering certified waste materials (for example, glass, metal, plastic and paper) to make new materials or products. Some recycled organic materials are rich in nutrients and can be used to improve soils. The conversion of waste material into soil additives is called composting, recycling and composting that generates many environmental and economic benefits. For example, they produce compost that improves the soil and reduces greenhouse gas emissions.

Elimination (landfill and combustion):

These activities are used to manage waste that cannot be prevented or recycled. One way to dispose of wastes is to place them in properly designed, constructed and managed landfills, where they are safely contained. Another way to handle this waste is through combustion. Combustion is the controlled burning of waste, which helps reduce its volume. If technology is available, properly designed, constructed and managed landfills can be used to generate energy through methane recovery. Similarly, combustion facilities produce current and water as a byproduct that can be demanded to generate energy.
