3. ●Solid waste means any garbage, refuse, sludge from a
wastewater treatment plant, water supply treatment plant,
or air pollution control facility and other discarded materials
● Solid or semisolid, nonsoluble material, such
as agricultural refuse, demolition waste, industrial waste,

What is solid waste?
4. • Garbage
• Rubbish
• Dead animals

6. Consist of household waste, construction waste, and
demolition debris, sanitation residue, and waste from

food habits, the amount of municipal solid waste has
been increasing rapidly and its composition changing.

8. Hazardous wastes are those that can cause harm to human and the
environment.
Characteristics of Hazardous Wastes:
• Toxic wastes:
Toxic wastes are those that are poisonous in small or trace amounts.
• Reactive wastes:
Reactive wastes are those that have a tendency to react vigorously with air or water
are unstable to shock or heat, generate toxic gases or explode during routine
management.
• Infectious wastes:
Included human tissue from surgery, used
bandages and hypoderm needles hospital
wastes.
• Corrosive wastes:
Are those that destroy materials and living
tissues by chemical reactions
Hazardous waste

which is generated
during the diagnosis,
treatment or
immunization of
human beings or

10. This process of waste disposal focuses attention on burying the waste
in the land.
Landfill
It is a disposal method in which municipal solid wastes are burned
at high temperatures so as as to convert them into residue and
gaseous products.
This process is also known as thermal treatment where solid waste
materials are converted by Incinerators into heat, gas, steam and
ash.
is a easy and natural bio-degradation process that takes organic wastes
i.e. remains of plants and garden and kitchen waste and turns into nutrient
rich food for your plants.
Incineration/Combustion
Composting
Methods of disposal waste
11. RECOVERY AND RECYCLING
Resource recovery is the process of taking useful discarded items fora
specific next use.
Recycling is the process of converting waste products into new products
to prevent energy usage and consumption of fresh raw materials.
REDUCE - to buy less and use less.
REUSE - elements of the discarded item are used again.
RECYCLE - discards are separated into materials that may be incorporated into new
products.
12. • Solid waste thrown in streets, highways, and waterways
can cause pollution when they are carried off by
rainwaters run-offs or by flood to the mainstream or
drainage.
• Burning of industrial waste produce furans,
droxins, that are harmful to human beings.
• Toxic substances may contaminate the
groundwater
