pesticides, crops,
water coming from
the fields also
consists of small
amount of toxic
chemicals.

expired medicines,
syringes, medical
instruments such
as scissors, blades
etc.

highly dangerous
and requires
proper disposal.

and reactive
materials, gases
etc.

Management Hierarchy

19. These are the following methods for disposal of the
solid waste.
• LAND FILLS
• BIOLOGICAL REPROCESSING
• RECYCLING
• OCEAN DUMPING
Methods of Disposal

20. LAND FILL
 It is the most traditional method of waste
disposal.
 Waste is directly dumped into disused quarries,
mining voids or borrow pits.
 Disposed waste is compacted and covered with
soil to prevent vermin and wind-blown litter.
Methods of Disposal

21. OCEAN DUMPING
 Ocean dumping is the dumping or placing of
materials in the ocean, often on the continental
shelf.
 A wide range of materials is involved, including
garbage, construction and demolition debris,
sewage sludge, dredge material, waste
chemicals, and nuclear waste.
 Sometime hazardous and nuclear waste are also
disposed but these are highly dangerous for
aquatic life and human life also.
Methods of Disposal

22. BIOLOGICAL PROCESSING
 Materials such as plants, food scraps, and paper
products can be decomposed into the organic
matter.
 The organic matter that is produced from this type
of recycling can then be used for such things as
landscaping purpose or agricultural uses.
 Usually this method of recycling is done by putting
the materials in a container and let to stay there
until it decomposes.
Methods of Disposal

23. RECYCLING PROCESS
• COLLECTION: The first step required for recycling is
collecting recyclable materials from communities..
• SORTING: This includes sorting the materials into
groups, cleaning them and getting them ready to be
sold to manufacturers who will turn the materials into
new products.
• MANUFACTURING: The collected material is sent to
industries those convert them into new products
Methods of Disposal

24. RECYCLING PROCESS
• PURCHASING: When consumers purchase products
that have been made with post consumer material
the recycling process has been completed and then
can be repeated.

25. Material Recovery Facilities

26. Operations
Information Campaign
 Increase awareness..
 Increase attendance in coastal cleanup activities and
street cleaning
 Support more in tree growing activities.
 People should learned proper disposal of solid waste
and initiated to clean up their surroundings.

28.  7.2 million tonnes of hazardous waste
 One Sq km of additional landfill area every-year
 Rs 1600 crore for treatment & disposal of these
wastes
 In addition to this industries discharge about 150
million tonnes of high volume low hazard waste
every year, which is mostly dumped on open low
lying land areas.
