:( World wide, rainforests are disappearing at a rate of one and a half football fields per second.
:( Americans consume 22% of the worlds oil, even though they make up just 5% of the world's population - as a result the past 100 years has seen heat trapping gases increase by 22%

SIX ELEMENTS OF Solid Waste Management
:) Transportation and transfer,
:) Processing and Treatment
Waste Disposal Method
:) Open Dump
:) Ocean Dumping
:) Exporting Waste
Sanitary landfills are sites where waste is isolated from the environment until it is safe. It is considered when it has completely degraded biologically, chemically and physically. In high-income countries, the level of isolation achieved may be high. However, such an expensive high level of isolation may not be technically necessary to protect public health. Four basic conditions should be met before a site can be regarded as a sanitary landfill.
- Full or partial hydrogeological isolation: if a site cannot be located on land which naturally contains leachate security, additional lining materials should be brought to the site to reduce leakage from the base of the site (leachate) and help reduce contamination of groundwater and surrounding soil. If a liner - soil or synthetic - is provided without a system of leachate collection, all leachate will eventually reach the surrounding environment. Leachate collection and treatment must be stressed as a basic requirement.
- Formal engineering preparations: designs should be developed from local geological and hydrogeological investigations. A waste disposal plan and a final restoration plan should also be developed.
- Permanent control: trained staff should be based at the landfill to supervise site preparation and construction, the depositing of waste and the regular operation and maintenance.
- Planned waste emplacement and covering: waste should be spread in layers and compacted. A small working area which is covered daily helps make the waste less accessible to pests and vermin.
-Although most industrialized nations in the world have agreed to stop shipping hazardous and toxic waste to less developed countries, the practice still continues.-
-Toxic wastes are sometimes “recycled” as building materials, fertilizer or soil amendments.
Incineration is a waste treatment technology that involves the combustion of organic materials and/or substances. Incineration is burning refuse to reduce disposal volume by 80-90%. Energy recovery is possible through heat derived from incineration. Steam from this process can be used for heating buildings or generating electricity. Mass burn means everything smaller than major furniture and an appliance is loaded into furnace. It results in greater problems with air pollution. Residual ash has toxic components including dioxins. High construction costs and environmental regulations have resulted in closures and waste exportation.
Waste implies unnecessary depletion of natural resources, unnecessary costs, and environmental damage. Sustainable waste management is about using resources more efficiently.
Issues & Problems
Litter at the roadside, drains clogged up with rubbish and rivers filled with filthy garbage definitely indicate that solid waste is a major environmental problem in
As of the year of 2008, 23,000 tones of waste is produced each day in
Despite the massive amount and complexity of waste produced, the standards of waste management in
Furthermore, the lack of awareness and knowledge among Malaysian community about solid waste management (SWM) issues, and being ignorant about the effect that improper SWM has to us has definitely worsened the problem.
Types of waste:
– Municipal waste (food, rubbish, ashes, construction waste, furniture)
– Industrial waste (waste from factories)
– Hazardous waste (waste that poses substantial danger such as flammable and explosive)
