The rate of generation
of solid wastes ranges from 4000 to 4500 tonnes per day is the three
major cities Delhi, Culcutta and Mumbai and the pathogenic organisms
in urban refuse lead to serious deseases such as cholera, typhoid,
dysentry, diarropea, malaria, plague etc. Dirporal of solid water
is being attended by the Government, but as waste volumes generated
an huge, they are posing problems of collection, transportation,
treatment and ultimate disposal. In all most all Indian cities and
else where is the world, the urban solid wastes are collected, though
not effectively, transported and disposed off as land fill which
is not very safe and hygenic method of solid waste disposal. As
the urban solid wastes contain organic matter and other plant nutrients
in varying proportions the emphasis all over the world is to treat
them in such a way that they are converted as manurial resources. |
