Proper disposal of waste/waste management

1. SOLID WASTE DISPOSAL

2. WHAT IS SOLID WASTE?
● 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,
mining residues, municipal garbage, and sewage sludge.

3. EXAMPLES:
o Garbage
o Rubbish
o Dead animals
o Large waste
o Waste tires
o Appliances and vehicles
o Latex paints
o Scrap metal

4. Municipal Waste
Hazardous Waste
Bio-Medical Waste

5. MUNICIPAL WASTE
Consist of household waste, construction waste, and
demolition debris, sanitation residue, and waste from
streets.
With rising urbanization and change in life style and
food habits, the amount of municipal solid waste has
been increasing rapidly and its composition changing.

6. CLASSIFICATION OF MUNICIPAL WASTE
Biodegradable
Vegetables
Fruits
Pulses
Cereals
Cloth
Paper
Non-
biodegradable
Plastic
Iron
Tires
Aluminum
Glass
Metals

7. HAZARDOUS WASTE
 Hazardous wastes are those that can cause harm to human and the
environment.
• 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.
Characteristics of Hazardous Wastes:
• Corrosive wastes:
Are those that destroy materials and living
tissues by chemical reactions

8. BIO-MEDICAL WASTE
Bio-medical waste means any waste, which is generated
during the diagnosis, treatment or immunization of human
beings or animals or in research activities pertaining thereto
or in the production or testing of biological.

9. METHODS OF DISPOSAL WASTE
 This process of waste disposal focuses attention on burying the waste
in the land.
Landfill
 is a type 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

10. Recovery and Recycling
 Resource recovery is the process of taking useful discarded items for a
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.

11. CAUSE AND EFFECTS
• 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

12. SOLUTIONS
 Compost your waste
Composting waste in an option for getting rid of your
household waste. You can compost lots of items. Anything
that that is organic can be composed.
 Recycling
Recycling waste is another option for getting rid of waste.
 Buy products that are good for the Environment
Instead of purchasing those plastic pop bottles, find a way
that you can buy things that are more environmentally
friendly.
