Waste Disposal
Waste management simply means the collection, transport, processing or disposal, managing and monitoring of waste materials to minimize its consequences on humans and environment.
![Page 19: Ppt on Waste Management](https://reader035.vdocument.in/reader035/viewer/2022081418/563db8c0550346aa9a9695ca/html5/thumbnails/19.jpg)
Areas included in waste management
Generalisation of waste Recycling and reuse Storage,collection,transport and transfer Treatment Waste minimiation Planning and implementation

Common ways of managing wastes
Incineration method This simply means burning waste.
This method is common in countries with limited landfill space.
It is great for treating waste with contamination (like those from hospitals) and hazardous waste from factories, but the method produces too much carbon dioxide.
Modern incineration processes are more efficient and release less dioxin.
This method is very common in Denmark, Germany and the Netherlands.
This method is effective, but expensive.

Sanitary landfills
Generally, this term means a large piece of land away from living places where all the waste from a town is deposited.
Proper landfill management involves sorting out all the waste (waste separation), and sending only the waste that cannot be recycled and composted to the site.
This method is effective, but expensive and difficult.

Waste RecyclingRecycling is processing used materials (waste) into new, useful products
Recycling also uses less energy and and great way of controlling air, water and land pollution.
Waste items that are usually recycled include:Paper wastePlastic wasteGlass wasteAluminium waste
When these are collected, the are sent to the recycling unit, where all the waste from each type are combined, crushed, melted and processed into new materials.

PlasticsUses
Food storage and packaging
Household items
Furniture
For preparing foods
Disadvantages
Disposal of plastic and their byproducts create pollution
Cause wide range of negative health effects
Contain chemicals and metals which is toxic in nature

Burning of plastics Open burning of plastic waste is simply dangerous to health
On burning carbon dioxide,dioxin and furan are released
Studies linked dioxins and furans to cancer and respiratory diseases
To inhale dioxin or exposed to the fumes can cause hormonal imbalance
