There is a continuous increase in expenditure for running municipal water supply systems in India. Many water treatment plants of various capacities are being constructed to cope with the increasing water demand. Now the most efficient and cost effective way to supply water to a locality with maximum production cost is to be found out to maximize the benefit from the fund spent.

The municipal solid waste generation is increasing in urban areas. The incineration of organic fraction of municipal solid waste (OFMSW) with high moisture content and low calorific value is not environmentally, techno-commercially viable option for energy recovery.

Batch digestion of vegetable waste slurry was carried out in the laboratory using 2.5L capacity bottle reactors for 60 days at ambient conditions. The biogas yield from vegetable waste over the length of the digestion time was observed to be 0.391L/g of VS fed.

Concerns for energy conservation, developing sustainable energy sources and interest towards national energy security benefits combined with growing environmental pollution is necessitating the search for renewable energy sources. Of the renewable energy sources, biomass is highly flexible and the least cost alternative.

Air quality crisis in cities is attributable mainly to vehicular emissions. Transportation systems are expanding everywhere. This paper examines the pollutant emissions from automobiles and identifies that the capacity of routine monitoring networks and impact assessment in India is usually limited to criteria pollutants.

Treatment of wet organic waste such as kitchen waste has been currently one of the important environmental issues that need to be resolved. Kitchen waste has a potential to recover biogas by application of anaerobic treatment.
