What is

Solid Wast

e?

The term solid waste means :Material such as household garbage, food wastes, yard wastes, and

demolition or construction

debris.

Any useless and unwanted material is termed as waste

Solid wastes are all the discarded

solid materials

from municipal, industrial,

and agricultural activities.

Municipal Solid wastes

Classification of Solid Waste

Municipal Solid wastes: Solid wastes that include household garbage, rubbish, construction & packaging materials, etc. and are managed by any municipality.

Bio-medical wastes: Solid or liquid wastes including containers, products generated during diagnosis, treatment & research activities of medical sciences.

Industrial wastes: Liquid and solid wastes that are generated by manufacturing & processing units of various industries like chemical, petroleum, coal, metal gas, paper etc.

Agricultural wastes: Wastes generated from farming activities. These substances are mostly biodegradable.

E-wastes: Electronic wastes generated from any modern establishments. They may be described as discarded electrical or electronic devices. Some electronic scrap components, such as wires, circuits, mobile, computers etc.

Sources of Waste

Muncipal solid waste generation

in india

7.2 million tonnes of hazardous waste. One Sq. km of additional landfill area is needed 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.

Solid Waste in India

In Mumbai (2005) the sewage line is cloged due to large no. of plastic bags.

Blast in the Bhusan Steel factory at Noida, caused due to imported scrap from Iran.

Reduction in the number of migratory birds due to consumption of contaminated foods.

Animals dying on streets due to consumption of plastic bags, which blocks the food movement in their stomach .

How solid waste affected us in recent years?

Impacts of solid

waste on health

Nausea and vomiting

Low birth weight

Cancer

Chemical poisoning through chemical inhalation

Increase in hospitalization

of diabetic residents living

near hazard waste sites

Mercury toxicity from eating fish with high levels of mercury Impacts of

Solid waste on health

Population growth

Increase in industrials

manufacturing

Urbanization

Causes of increase in solid waste

Waste management is the storage collection transport and handling recycling disposal and monitoring of

waste materials.

Solid waste management

Storage: - Galvanized steel dust bin - Paper sack - Public bins

storage

Collection - House-to-house collection - Collection from the public bins

collection

Waste handling and separation involves activities associated with waste management until the waste is placed in storage containers for collection. Handling also encompasses the movement of loaded containers to the point of collection.

waste is transferred from a smaller collection vehicle to larger transport equipment

Waste handling and

transport

1. Dumping2. Controlled Tipping or Sanitary Landfill3. Incineration4. Composting5. Manure pits6. Burial

Method of disposal

It is the most traditional method of waste disposal. Waste is directly dumped into quarries, mining

voids or borrow pits. Disposed waste is compacted and covered with

soil. It is generally used for domestic waste.

Land Filling

A Land Fill Site

Incineration is a waste treatment process that involves the combustion of solid waste at 1000^o C.

waste materials are converted into ash, flue gas, and heat.

The ash is mostly formed by the inorganic constituents of the waste and gases due to organic waste.

The heat generated by incineration is used to generate electric power.

Know 3R’s Concept and Justify Aspects and Issues related to recycling and composting of municipal

solid waste (MSW).

How can we make a change

Reduction• By reducing, consumer and industry can save natural

resources and reduce waste management costs.

Reuse• Large production companies such as Electronic,

appliances and gadgets, should establish the collection centre, where damaged items can be repaired and reuse.

Recycling• Recycling turns materials that would otherwise become

waste into valuable resources.

Waste generation and waste reduction reflect many complex economic and social factors. No city or town can adopt recommendations in a vacuum; each must examine its own wastes, and the potential for extending waste reduction.
