The document discusses landfill diversion and different types of landfills. It defines landfill diversion as the process of diverting waste from landfills. The success of landfill diversion efforts can be measured by reductions in the quantity of waste dumped in landfills compared to previous years. Different types of landfills are described, including open dumping, sanitary landfills, secure landfills, and deep well injection. Various methods for landfill diversion are also outlined, such as waste reduction, recycling, incineration, biological treatment, returning waste to suppliers, reuse in production processes, selling waste to third parties, and converting waste to energy.

Landfill Diversion

2. Landfill Diversion
 The process of diverting waste from landfills is known as landfill
diversion.

3. Measuring success of Landfill Diversion
 The success of landfill diversion can be measured with respect
to the reduction in quantity of waste that is dumped into landfill
as compared to the previous year. If the quantity of waste
dumped into landfill remains the same or is reduced, the
campaign of landfill diversion is said to be successful.

4. Types of Landfill
 Open dumping
Waste is disposed in an open land with no restrictions or regulation.
This is the
worst option as it is harmful for environment and open dumps are
prohibited in
many countries.

5. Types of Landfill (Cont)
 Sanitary Landfill
Waste is disposed of in thin layers. Each layer is covered and
compacted with
soil to prevent foul odors and wind blown litter. This method is very
effective
in terms of public hygiene.

6. Types of Landfill (Cont)
Requirements of Sanitary Landfill
 The landfill must have absolute leachate security. The
bottom of the landfill must be lined to prevent water
contamination.
 Engineering preparations and planning must be carried out
to ensure the success of the landfill.
 To ensure success and sustainability, permanent
supervision must be present in all stages of the landfill.
 The placement and compacting of waste must be done to
prevent pest and vermin infestations.

7. Types of Landfill (Cont)
Secure Landfill
 It is used to deal with hazardous waste. A secure
landfill requires much more stringent regulation than
municipal waste.

8. Types of Landfill (Cont)
Deep Well Injection
 In Deep-well injection, the liquid waste is pumped into porous
limestone or sandstone through a steel casing. High pressure is
applied to permanently store the waste in the pores of the rocks.

9. Types of Landfill Diversion
 Waste reduction
This can be done by reducing the use of plastic bags, excess packaging,
etc.

10. Types of Landfill Diversion
(Contd)
Recycling
 This is the process of creating new and usable
products from waste. Materials like paper, plastic,
aluminium cans can be recycled.

11. Types of Landfill Diversion
(Contd)
Incineration
 In this process, waste is burnt. the process is not helpful for a
sustainable environment.

12. Types of Landfill Diversion
(Contd)
Biological Treatment
Food waste, wood chunks etc. can be put in a compost where it
can be treated
along with biological enzymes.

13. Types of Landfill Diversion
(Contd)
Return waste to supplier of original materials
Products like soft drink bottles made of glass can be returned to
the company
through the shopkeeper.

14. Types of Landfill Diversion
(Contd)
Reuse waste in the production process
A closed loop recycling system can be implemented in
manufacturing units to
reduce the amount of waste. This can also add to the efficiency
and
profitability of the process.

15. Types of Landfill Diversion
(Contd)
Selling waste to a third party
 The waste produced by a manufacturing unit can sometimes be
a great resource for another one.

16. Types of Landfill Diversion
(Contd)
 Waste to Energy
Waste can be converted to useful form of energy like fuel, heat or
electricity.
