2. WHAT IS SOLID WASTE
MANAGEMENT?
Solid-waste management is the collecting, treating, and
disposing of solid material that is discarded because it has
served its purpose or is no longer useful.
3. CAUSES OF SOLID WASTE
MANAGEMENT
• Improper waste disposal
• Littering is another major cause of solid waste pollution.
• Accidental spills of hazardous materials can also cause
solid waste pollution.
4. Effects of solid waste
Effects of Improper solid waste disposal causing many problems to
the health and environment.
1.Land & Water Contamination
Solid waste management is the major cause of land and water
contamination. Day-by-day land slowly loses its fertility, clogging
drains, causing air pollution and collapsing the food chain. Surface
water level decreases, drinking water quality gets poor, and it
transmits diseases such as cholera, diarrhoea, and hepatitis
5. 2.Litter Surroundings
Solid waste management is an important element in maintaining hygienic
and sustainable living conditions within human settlements.
3.Emission of Toxic gas
Hazardous wastes affect the environment and human health and
sometimes lead to death. These hazardous wastes are thrown away
without being properly disposed of, increasing the risk to the environment
and human health.
4.Impact on Human health
Untreated solid waste can also cause environmental pollution and spread
infectious diseases. The health of the people who live close to a waste
dump is under direct threat. Solid waste, such as paper and plastic, may
cause harmful infections and even injuries through cuts.
6. Treatment methods of solid waste
management
• Recycling
• Recycling is the art of handling waste without getting wasted.
Recycling of waste varies with the category or type of product.
Recycling solid waste should be done to pose no health risks to the
general public and not damage the environment.
• Incineration
• The incineration method implies the burning of wastes in a
combustion house of heat at a high temperature.
7. Source Reduction
Source reduction is inspired by nature, where everything becomes part of
another cycle. It is also a social system that ensures that the benefits are
distributed equitably among all community members regardless of their
economic status.
Composting
Composting eliminates the acquiring space for landfills. The collected
organic wastes can be sorted and buried in the land with prospective
measures. Only Biodegradable waste can be decomposed using
Composting.
