The document discusses biodegradable and non-biodegradable wastes. Non-biodegradable wastes such as plastics, metals, and chemicals cannot be broken down by living organisms and have negative effects including releasing greenhouse gases and polluting air and water. They also reduce soil fertility and harm aquatic life and crops. The document suggests alternatives to non-biodegradable materials such as paper, wood, natural fibers, and bioplastics, and provides examples of common non-biodegradable wastes.

2. Biodegradable & Non-biodegradable
◦Biodegradable waste is a type of
waste, typically originating from
plant or animal sources, which may
be decomposed by other living
organisms. While Wastes that cannot
be broken by other living organisms
are called non-biodegradable.

3. Effects of non-biodegradable
◦-Rapid release of methane
◦ -Greenhouse gases that may cause
global warming
◦-air and water pollution
◦ -produce diseases and harmful
gases
◦-reduce soil fertility
◦ -affect aquatic life and crops

4. Alternatives
◦-Paper
◦-Wood
◦-Natural fibre clothes
◦-Bio plastic which is plastic made
from plants
◦-Potteries

5. Examples of non-biodegradable
-Plastics
-Metal
-Aluminium cans
-Tyres
-Toxic chemicals
-Polystyrene
