The document discusses the importance of proper solid waste disposal in promoting public health and preventing diseases. It outlines the environmental impacts of poor waste management, including contamination of water sources and the attraction of pests. Various waste disposal methods are described, including landfill, incineration, and composting, with their associated technologies and considerations.

4. INTRODUCTION
4
 Waste produced by human activities is
increasing in most parts of the World.
 The output depends on the degree of
urbanization, dietary habits, lifestyles and
living standards.
 In most of the countries the per capita daily
solid waste produced is between 0.25 to 2.5

5. DEFINITION
5
Solid wastes include materials that are not
economically useful, present in solid, liquid
or gaseous form, which originate from a wide
range of human operations, such as industry,
commerce, transport, agriculture, medicine
and domestic activities.
Dr. Rahul B. Pandit

6. CLASSIFICATION
6
 Based on place of generation. E.g.
institutional. Industrial and domestic.
 Based on content of waste. E.g. glass waste,
plastic waste, metal and organic waste.
 Based on risk potential. E.g. infectious,
toxic, non toxic and inflammable.
Dr. Rahul B. Pandit

7. ENVIRONMENTAL IMPACT
OF SOLID WASTE DISPOSAL
7
 Contamination of ground water by leachate
generated by waste dump
 Surface water contamination by run-off from
the dump Waste decomposes and favors fly
breeding, attracts rodents and pests
 It is aesthetically unpleasant and generates
foul odor.
Dr. Rahul B. Pandit

8. ENVIRONMENTAL IMPACT
OF SOLID WASTE DISPOSAL
8
 Generation of inflammable gas such methane
and green house gases inside the waste
dump
 Transmission of disease through pests, stray
animals and cattle

9. SOLID WASTE MANAGEMENT
9
 Waste generation
 Waste handling
 Sorting, storage and processing at source
 Collection
 Sorting, processing and transformation
 Disposal

11. DISPOSAL OF SOLID WASTE
11
 The choice of disposal method depends on the
economic considerations, availability of land,
local labour and circumstances.
 Some of the technologies in use include
sanitary landfill, incineration, composting,
biogas plant, Effective Microorganisms
technology and salvaging.
Dr. Rahul B. Pandit

12. DUMPING
12
 The waste collected from the
cities and municipal areas
are dumped in the low lying
areas or open tracts of
lands, usually by the
roadside.
Dr. Rahul B. Pandit

13. LANDFILL
13
 Landfill (Controlled tipping) is a method of
selecting depressed areas or creating
artificial trenches where waste matter is
thrown and compacted with a layer of earth
on top of it.
Dr. Rahul B. Pandit

14. COMPOSTING
14
 It is a method where in the combined
disposal of solid waste is carried out along
with stable litter, night soil and sludge.
Compost is humus like material, which is
generated due to the breakdown of organic
matter under bacterial action, and is rich
manure.
