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.

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.

Importance of waste recycling

Protect the environment Conserves natural resources Saves energy

Effects of waste

Surface water contamination

Soil contamination

Can you guess this place????

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

What we can do?

Substitute plastic bypapers,ceramics,glass,stainless steel

Avoid heating foods in plastic containers

Avoid transferring hot food,drinks into plastic containers.

We have a role to play

Reduce creating wastes Get your own shopping bags Re use things such as

clothing,paper,furniture,package boxes Lead and join environmental society
