Abstract:
More than thirteen thousand metric ton of Municipal Solid Waste (MSW) is
generated each day in Bangladesh currently where only 37% are collected by the
authority. Experts predict that more than 47 Metric ton of MSW will be generated
by 78 million of urban people by in 2020. So the management of MSW is and
will be one of the major challenges of Municipal Authority of Bangladesh.
Improper management of municipal solid waste (MSW) causes hazards to
inhabitants. Various studies reveal that about 90% of MSW is disposed of
unscientifically in open dumps and landfills, creating problems to public health
and the environment. Bioconversion of MSW can be a better alternative to avoid
environmental pollution. But the decomposition of MSW is not the best way for
compost preparation. Grass Clippings (GC) at optimum level can help promote
the compost process in more effective way. Optimum amount of GC along with
optimum level of cow dung (CD) for the compost preparation from MSW are
critically studied. In this study, MSW amended with bulking materials GC and
nitrogen source cow dung (CD) were evaluated for improved stability and
maturity during composting of MSW where 15 kg GC and 5 kg of CD showed
the most promising efficiency in terms of physical, and chemical parameters.
The study is concluded with a few fruitful suggestions that is use of other
lignocellulosic materials like water hyacinth and herbaceous weeds can also be
used instead of grass clippings which may be beneficial to encourage the
competent authorities/researchers to work towards further improvement of the
present system.
