The document provides an overview of waste management, including activities such as collection, transportation, segregation, recycling, and disposal of different types of waste. It classifies waste into categories such as municipal solid waste, construction waste, industrial waste, biomedical waste, and e-waste, while also outlining relevant laws and disposal methods like landfilling and incineration. Additionally, it emphasizes the importance of managing waste effectively through new technologies and promotes a waste hierarchy of reduce, reuse, and recycle.

3. Introduction
Waste management refers to the activities connected with
the collection and disposal of wastes. Waste management
comprises the following activities:
1. Waste collection
2. Waste transportation
3. Waste segregation
4. Waste recycling
5. Waste disposal
6. Waste minimization and control

4. CLASSIFICATION OF WASTE

SEWAGE &
SLUDGE
SOLID LIQUID
HAZARDOUS
NON-
HAZARDOUS

WASTE WATER

5. URBAN WASTE
SOLID WASTE
1) MUNICIPAL SOLID WASTE :
Recyclable , biodegradable as well as inert waste
Recyclable: paper, glass, plastic etc
Biodegradable: food wastage from household.
2) CONSTRUCTION WASTE:
Solid waste generated by the construction, repair, alteration or
demolition of building, road, bridge etc.

6. LIQUID WASTE
1) SEWAGE & SLUDGE :
Sewage water carried waste, in solution or suspension, it is more
than 99 per cent water.
Sludge is the semi-solid precipitate produced in waste water
treatment plants originating from their process of treatment.

7. INDUSTRIAL WASTE
SOLID WASTE
1) HAZARDOUS WASTE:
a) Listed wastes : eg: commercial chemical products
b) Characteristics wastes: eg: harmful, explosions etc.
c) Universal wastes: eg: batteries. Pesticides etc.
d) Mixed wastes: eg: cyanides, heavy metals etc.

8. 2) NON- HAZARDOUS WASTE :
packaging waste, glass, metal scrap etc.
LIQUID WASTE
1) INDUSTRIAL WASTE WATER :
Toxic chemical from electroplating, cooling water from
thermal power plats etc.

9. BIOMEDICAL WASTE
• Waste generated from hospitals
• Waste generated from Health care facilities
• Waste generated from Health research laboratories.

10. E- WASTE
• Electronic waste loosely discarded, surplus, obsolete, broken,
electrical or electronic devices.

11. Law
 The Water Act 1974
 The Water Rules 1975
 The Water Cess Act 1977
 Water Cess Rules 1978
 The Air Act 1981
 The Environment Act 1986
 The Manufacture ,Storage and Import of Hazardous Chemical Rules
1989
 The National Environment Appellate Authority Act 1997
 The Bio-Medical Waste Rules 1998
 Batteries Rules 2001
 National Green Tribunal Act 2010
 The Plastic Waste Rules 2011
 E- Waste Rules 2011

12. Disposal Methods
1)Land filling 8) sewers and drain pipes
2)Burial 9)soak pits
3)Incineration
4)Composting
5) Vermicomposting
6)Biogas
7)Recycling

13. 1. Land filling : select low lying sites at least 45 m
away from habitation, start filling at one end,
garbage should be properly compacted and
covered with earth.

14. Burial : dig deep trenches, cover garbage
with soil, deposit garbage daily.

15. Biogas : gas produced by biological breakdown
of organic matter in the absence of oxygen.
(biofuel)

16. Incineration : converts the waste into
incinerator bottom ash, flue gases, and heat
which can in turn be used to generate power.

17. Composting : composting of organic
materials such as food scraps.

18. Vermicomposting : consumption of
organic material by earthworms.
(biofuel)

19. Recycle: once a product has been used, it
has the potential to be recycled into
something new.

20. Sewers & drainpipes: drains should not get
blocked, sewers should have no leakage.

21. Soak pits : it is a covered pit dug in the ground,
in which effluent from the septic tank is
discharged. It is generally dug in the previous
soil which can absorb the effluent. The
container which receives the wastewater
should be cleaned fortnightly.

22. How to manage waste effectively
• New technologies and machines
• Optimum use of available resources
• increasing staff morale and environment
awareness
• Use reusable things

23. WASTE HIERARCHY
REDUCE
REUSE
RECYCLR
