Waste Management: A Case Study of Ongoing Traditional Practices at East Calcutta Wetland | Science Publications

摘要

> Calcutta has a unique waste management system which uses the traditional non conventional practice for treating both the solid as well as soluble waste for its 12 million inhabitants . It not only detoxifies the waste but also generates resources for the existing society in form of employment as well as edibles like sufficient vegetable, fish as well as paddy for consumption. The elemental analysis of these products showed no metal toxicity due to their cultivation using waste resource. Thus East Calcutta Wetland can be sited as the best example of integrated resource recovery.
