municipal solid wastes

non-municipal solid waste

bio-degradable

non-biodegradable

increase of disease

radioactive substance causes disease

reduce aesthetic value of land

decomposition take place

pollutant run off with rain and mixes with the nearby water bodies causing water pollution

non-biodegradable solid wastes release toxic gas when burnt, which causes air pollution

source reduction

is conducted when the materials are used again

advantages

is the revcoverage of useful materials

composting -nature's way of recycling

enclose the solid waste

to prevent the toxic substance releasing to the environment

burning of solid waters in furnaces

pyrolysis

application of chemical reagents to destroy the toxic composition

composting

refers to uncovered areas

the waste is untreated and not segregated

it's the bredding ground for flies...spread disease

the rainwater run-off from these dumps contaminates nearby land and water

comnustion of waste materials in the presence of oxygen at a temperature of 1000°C and convert wastes to ash, gas, and water vapor

it's commonly used as a means of recovering energy from electricity or heating

problems

is a site for disposal of waste material by burial

Poorly designed or managed landfills can create adverse environmental impacts

sanitary landfills are designed to reduce the risks

sanitary landfill area can be comprised of clay soil

the use of sanotary landfills presents less health and environment risk

refers to packing waste materials incontainers made of impervious and non-reactive material
