This presentation show about the solid waste pollution and the control the pollution around the environment. If you read this slide you will understand that pollution will cause more than you expected around your atmosphere. Try to look on this slide

1. SOLID WASTE POLLUTION

2. ENVIRONMENT AND RELATED CONCEPTS
• Environment :-The surroundings of an organism in which the organism
lives. It includes the abiotic and biotic things.
• Environmental Engineering :- Environmental engineering is the
systematic study of our environment and our proper place in it.
• Environmental Pollution :- The addition of undesirable substances or
energy(heat , radiation and noise) into physical environment (air , water
and land),making it less fit or unfit for life.

3. What is Solid Waste???
• All solid and semi-solid wastes arising from human and animal activities
and are discarded as useless or unwanted are included in the term „solid –
wastes‟.
• Solid Waste is often called the third pollution after air and water pollution.
• It includes garbage , rubbish , ashes and residues , demolition and
construction wastes , dead animals , radio active wastes.
• The amount of solid waste produced in urban India is steadily and rapidly
increasing

4. Harmful Effects of Solid Waste
• Improper handling of solid wastes is dangerous to health and
environment.
• Improper disposal of solid wastes are resulted in the deaths of humans
and animals through contamination of crops of water supplies.
• Uncontrolled dumping of urban wastes destroys the beauty of the
countryside.
• Uncontrolled burning of open dumps can cause air pollution.
• Solid wastes is also responsible for water pollution.

5. Terms used in Solid Waste
• Garbage :- It includes putrescible organic waste like the animal, fruit or
vegetable residues resulting from the handling , preparation , cooking and
eating foods.
• Rubbish :-It includes combustible and noncombustible solid wastes ,
excluding food wastes or putrescible materials.
• Organic Wastes :-Wastes which includes animal and vegetable refuse ,
animal dungs , decay leaves etc. are called organic wastes.
• Inorganic Wastes :-Metal pieces , glass , ceramic tiles , dust , mud etc.
those are non combustible known as inorganic wastes

6. Source of Solid Wastes
Domestic Wastes :-waste that arises from household activities of human
beings, includes :
Garbage
Rubbish
Ashes
Industrial Wastes :- wastes, which arises from industrial activities,
includes :
Construction and demolition wastes
Discarded equipment and tools
Mining wastes etc.

7. Source of Solid Wastes
Agricultural Wastes :- These includes agricultural residues and poultry
and diary wastes . Further, agricultural wastes may also include packing
and cans of fertilizers, pesticides and soil conditioners used in modern
agricultural practices.
Commercial Wastes :-wastes, those arise from public places such as
offices, markets, restaurants, streets etc,.includes :
Building Wastes
Garbage
Hazardous Waste
Ashes
Rubbish

8. Types of Solid Wastes
• Biodegradable Wastes :-Wastes which can be broken down into simpler
and harmless substances by nature in due course of time using biological
means.
• Non-Biodegradable Wastes :- Wastes that can not be broke down into
simpler and harmless substances by biological means. Ex- plastics;
polythene bags; glass objects etc.
• Toxic Wastes :- which can pose an substantial danger to the health of
living beings and environment ,immediately or over an period of time. Ex-
pestisides; heavy metals like mercury; sulphur dioxide etc.

9. Types of Solid Wastes
• Non-toxic Wastes :- wastes that do not pose any problem to the health of
living beings or to the environment .These are generally domestic wastes
which are easily biodegradable. Ex- papers, rags, boards etc.
• Biomedical Wastes :- wastes generated from hospitals, health centres,
medical and dental colleges and laboratories. Ex- biological cultures, used
syringes etc. These wastes are potentially dangerous and infectious.

10. Solid Waste Management
It defines as the application of techniques that will ensure the orderly
execution of the functions of collection , processing and disposal of solid
waste. Three basic functional elements are :-
• Collection :- It refers to the gathering of solid wastes from places such as
residences, commercial, institutional and industrial establishments, and
other public places. Two methods of collection:
1-hauled –container system
2-stationary-container system

11. Solid Waste Management
• Processing :- It refers to the activity applied to solid waste to prepare it
for subsequent operation. Processing improves the efficiency of solid
waste disposal and prepares solid waste for subsequent recycling and
recovery of materials.
• Disposal :- It refers to the placing of solid waste in its ultimate resting
place

12. Techniques of Solid Waste Management
In Solid waste Management, the stress should be on 3R‟s-Reduce,Reuse and
Recycle as discussed below:
Reduction:-
Reduction in the use of raw materials is one of the fundamental way s to
decrease the production of solid waste.
On the individual level,one can reduce the use of unnecessary items while
shopping.
For example, Buy items with minimal packing,avoid buying disposable
items and also avoid plastic carry bags

13. Techniques of Solid Waste Management
Reuse:-
Reuse of the materials in their original form is the next fundamental way to
minimize the generation of solid waste.
The reuse of materials,instead of throwing them away,not only reduces
waste but also save money.
Recycling:-
Recycling involves reprocessing of discarded materials that may have
some economic value into new useful products.
Recycling will not only make materials available to future generations but
also save energy and environment.

14. Techniques of Solid Waste Management
Some examples of recycling and waste utilisation:-
Recycling of metals papers,glass and plastic.
Utilising fly ash in brick making
Paper from agricultural waste
Energy from urban waste
