Waste management


Increasing in manufacturing sector develop and boost up our economic growth and changed quality and way of our life. However, manufacturing factories produce huge amount of wastes. So, an efficient and effective waste management is necessary to treat the wastes produced.
In some developing countries and Third countries, the waste management standard is still poor, for example
1) Outdated and poor documentation or waste generation rates and composition
2) Inefficient storage and collection of wastes.
3) Disposal of municipal wastes that contains toxic and hazardous material.
4) Dumping of wastes
5) Inefficient use of disposal site space.
There is a hierarchy which lists the way of managing waste problems. It includes avoid creating of waste followed by re-use of waste, recycles waste, recovery energy from waste and lastly is the disposal of waste safety. Best option is the avoiding of create waste and the worst is disposal of waste safety. Principles for achieving good waste management are
1) Polluter pays-person or organization that generates waste shuld pay to manage it.
2) User pays-the costs of the resources needed to create goods and/or services should be included in their price to buyer.
3) Product stewardship-those who produce or import products should do everything possible to minimize the harm to environment caused by producing, using and disposing of the products.

Sustainable development should also be emphasized. It refers development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The dimensions include society, economy and environment.
