waste management and discover , recycle and reuse

1. Discover, recycle and reuse

2. Solid waste management
“It involves the collection, transport , processing ,
recycling or disposing and monitoring of solid waste
material”

3. Improper management
 Improper disposal Threats public health .Waste
enhances insects growth act as vectors of diseases
(transmit pathogens).
 It leads to terrestrial and aquatic ,air pollution and
water pollution .
 it causes Technical and environmental difficulties ,
economic and social problems

4. Objective for SWM (solid waste
management)
 Reducing the quantity of toxic and hazardous
chemicals and materials acquired, used, or disposed
off by the agency
 Increasing diversion of solid waste as required.
 Maintaining waste recycling programs .
 To Provide efficient and economical way of reuse of
collections through recycling.
 To provide Source for Energy generation
 To Reuse and Recover the materials from waste.

5. TYPES OF WASTES
residential commercial industrial
Municipal solid waste Hazardous waste

mining
construction
Municipal solid waste

6. Methods of SWM
 Composting
 Incineration or combustion
 Landfilling

7. Composting
 Composting involves the placement of carcasses
beneath organic materials, which promotes
decomposition at elevated temperatures and destroys
pathogens present in the carcasses”

8. Indoor composting
 It has been widely used by the poultry industry for bird
mortalities.
 Indoor composting is less affected by weather events,
ambient temperatures and seasonality and more
protected from wind, scavengers.

9. Outdoor composting
 It involves placement of carcasses in compost piles that
are long, narrow windrows or trapezoidal shaped and
above ground.
 May affected by weather events, ambient temperatures
and seasonality

10. Procedure:
 Place the carcass (or carcasses) on the bulking agent. If
you’re composting calves or other smaller animals, place
them starting at the back in a single layer, at least six inches
apart.
 Cover the carcass with another 12 inches of bulking agent.
If the bulking agent does not feel moist, add water before
covering the carcass
 Record the species, weight, date, and amount of bulking
material used
 When the first bin is full or the pile is as tall as you can
work with, start a second bin/pile if you have more
mortalities.

11. Incineration
 Waste treatment that involves combustion of
disposible substances at high temperature results in
ash, gases & heat.
 Chemical process :Combustible part is
combined with O2  CO2 + H2O (oxidation)

12. Open type incineration
 Open type incineration involves combustion of solid
material at open field using fuels (diesel, jet fuel,coal,)

13. Close type incineration
 Close type incineration is carried out by close
incinerator by using fuels such as Gas

14. Landfill method
 Ritual act of placing a dead person or animal, and/or
objects into the ground. This is accomplished by
excavating a pit or trench.
 Hazards and toxic substance can be dumped into soil
by landfill method in order to prevents spreading

15. Precautions while selecting site for
landfilling
 Not floody area
 500 feet from residences, livestock facilities and
adjacent pastures owned or leased by another person.
 300 feet from a road.
