S lid WasteManagement
Solid or semi-solid material - which are non soluble in nature.
In Simple Words Solid wastes are any discarded (abandoned or considered waste-like) materials. Solid wastes can be solid, liquid, semi-solid or containerized gaseous material.
.
What is Solid Waste?
Source of Waste
Households or Municipal Wasteincludes food,
paper, cardboard, plastic, textiles, leather, glass, metal, ashes, electronics waste etc.
Source of Waste
Business and Industrial Wasteincludes toxic
chemicals, oil, debris from construction site, packaging waste, ashes etc.
Agriculture Wasteincludes
pesticides, crops, water coming from the fields also consists of small amount of toxic chemicals.
Biomedical Waste or Hospital Wastemedicine
bottles, expired medicines, syringes, medical instruments such as scissors, blades etc.
Nuclear Wasteincludes
radioactive substances coming from reactors, fuel (uranium, thorium, plutonium etc). Its highly dangerous and requires proper disposal.
Hazardous Waste
includes toxic chemical, acids, corrosive, ignitable and reactive materials, gases etc.
Hotel Wasteincludes left
over food, empty bottles, and different kinds of trash
Bio-degradablecan be degraded (food,
fruits and others)
Non-Biodegradablecannot be degraded
(plastics, bottles, old machines, cans, containers and others)

Solid WasteManagement Hierarchy
These are the following methods for disposal of the solid waste.
• LAND FILLS• BIOLOGICAL REPROCESSING• RECYCLING• OCEAN DUMPING
Methods of Disposal
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
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
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
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
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.
Material Recovery Facil it ies
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.
7.2 million tonnes of hazardous wasteOne Sq km of additional landfill area
every-yearRs 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.
