4. Solid waste management
● The term solid waste
management refers to the
complete process of collecting,
treating and disposing of solid
waste.
● They are collected from
different sources and then
disposed .It needs to be
monitored so that guidelines
are followed.
● It includes administration,
Planning, financial and legal
function.

6. MAJOR FACTORS THAT
CONTRIBUTE TO SOLID
WASTE POLLUTION
● COMMERCIAL
ESTABLISHMENTS
● RESIDENTIAL HOUSES
● DEBRIS FROM
CONSTRUCTION,DEMOLITI
ON AND ROADS
SCRAP FROM VEHICLES
● AGRICULTURE

7. ISSUES CREATED DUE TO
SOLID WASTE
● FOUL ODOUR
● SPREAD OF DISEASES
● TOXIC GASES EMISSION
● UGLY LANDSCAPE
● TRANSMISSION VIA FOOD CHAIN
● ENVIRONMENTAL POLLUTION
● LANDFILL TAKES UP VALUABLE LAND

8. CONSEQUENCES AND
HOW TO PREVENT THEM
Solid waste management
If not for efficient waste management,the streets
would be littered with filth and lakes and rivers
would become very toxic for life.Human health would
be severely affected if careful waste management
practices did not exist.Therefore,the major causes of
waste management practices come into play after
environment is to ensure that proper actions and
activities are undertaken from the initial creation to
final disposal.Ignorance of the environment’s plight
significantly contribuited to the creation of waste
management principles.
9. Solid waste management
DIFFERENT PROCESSES THAT ARE INCLUDED IN
CONTROLLING WASTE
COLLECTION
Transfer of solid waste
from point of use to the
point of treatment or
landfill.
TREATMENT
Various processes are
held at different steps.
DISPOSING
Different methods are
followed to properly
dispose the waste.
12. Solid waste management
LANDFILL
In this process,the waste that cannot be
reused or recycled are separated out and
spread as a thin layer in low-lying areas
across any city. A of soil is added after each
garbage layer.
DISADVANTAGE-
This land cannot be used for construction
for the next 20 years.Instead,can only be
converted into a park or playground.
13. Solid waste management
INCINERATION
Incineration is the process of controlled
combustion of garbage to reduce it to
incombustible matter such as ash and waste gas.
The exhaust gases from this process may be
toxic, hence it is treated before being released
into the environment. This process reduces the
volume of waste by 90 per cent and is considered
as one of the most hygienic methods of waste
disposaL.
DISADVANTAGE-
However, some consider this process, not quite
environmentally friendly due to the generation of
greenhouse gases such as carbon dioxide and
carbon monoxide.
ADDED ADVANTAGE-
The heat generated is used to produce electricity.
14. BIOGAS
GENERATION
Biodegradable waste, such as food items,
animal waste or organic industrial waste from
food packaging industries are sent to bio-
degradation plants. In bio-degradation plants,
they are converted to biogas by degradation
with the help of bacteria, fungi, or other
microbes. Here, the organic matter serves as
food for the micro-organisms. The degradation
can happen aerobically (with oxygen) or
anaerobically (without oxygen).
ADVANTAGE-
Biogas is generated as a result of this process,
which is used as fuel, and the residue is used
as manure.
15. COMPOSTING
All organic materials decompose with time.
Food scraps, yard waste, etc., make up for
one of the major organic wastes we throw
every day. The process of composting starts
with these organic wastes being buried
under layers of soil and then, are left to
decay under the action of microorganisms
such as bacteria and fungi.
This results in the formation of nutrient-rich
manure. Also, this process ensures that the
nutrients are replenished in the soil. Besides
enriching the soil, composting also increases
the water retention capacity. In agriculture, it
is the best alternative to chemical fertilizers.
16. VERMICOMPOSTING
Vermicomposting is the process of using
worms for the degradation of organic
matter into nutrient-rich manure. Worms
consume and digest the organic matter.
The by-products of digestion which are
excreted out by the worms make the soil
nutrient-rich, thus enhancing the growth
of bacteria and fungi. It is also far more
effective than traditional composting.
.
17. 3 R’S
In order to keep as much material out of the landfill as possible,
it’s important for each of us to do our part. One of the ways to
put that plan into action is through the 3 R’s of waste
management — Reduce, Reuse, Recycle.
1. Reduce means to cut back on the amount of trash we
generate.
2. Reuse means to find new ways to use things that
otherwise would have been thrown out.
3. Recycle means to turn something old and useless (like
plastic milk jugs) into something new and useful (like
picnic benches, playground equipment and recycling
bins).
18. CONCLUSION
In our society,there is relatively less
awareness about this problem .The behaviour
of generating garbage is not only harmful
for this generation but also the future
generation.It is necessary to educate people
about the 3 R’s instead of producing
unnecessary waste.It should be a main
priority of municipalities and government.
Individual involvement is necessary.
