The concern about global warming effects by continuous exploitation of non renewable fossil fuels and scarcity of electricity generation accelerates the urge for searching alternative source of energy. Development of Microbial fuel cell using microbes present in waste water is the novel approach to treat this hurdle. Apart from biopower generation, it acts as a biosensor. Microbes metabolizes the organic matter present in waste water during the process electricity is generated. Within course of time the wastewater is treated with Chlorella vulgaris for the removal of phosphate for about 50 percent present in water. The amount of electricity generated has increased. The biomass thus produced, can be used for biofuel generation. For further purification of this treated wastewater, a novel method of treating it with Strychnos potatorum (chilla ginjalu) seeds is attempted.
Microbial and plant fuel cell represents a new type of green technology for electricity generation. In this book, batch production of electricity using river water sediment and plant sediment is reported .Experiments were conducted in a single chamber microbial fuel cell and plant fuel cell to study the amount of electricity produced. The study revealed that river water sediments and plants could be used effectively for direct electricity generation in single dedicated fuel cell. Plant fuel technology is still in an early stage of development but shows great promise as new method for renewable electricity generation. Such a system can produce in-situ 24 hours per day green electricity without harvesting the plants. The Plant-MFC concept has several attractive qualities which can provide the significant breakthrough for sustainable energy production in India.

Microalgal biomass contains lipids, polysaccharides, proteins, pigments and other cell compounds, and it can provide different kinds of biofuels such as biodiesel, biomethane and ethanol; these microorganisms can also be used to produce bioplastic materials and the residual biomass can be applied as fertilizer.
Water is an essential resource for living systems, industrial processes, agricultural production and domestic use. It is one of the most precious gift of nature without which no life could survive on earth. In the recent past several studies have reported the water bodies becoming increasingly contaminated due to domestic and industrial waste. Water pollution affects our oceans, lakes, rivers, and drinking water, making it a widespread and global concern. This research focuses on synthesis of natural polymer based new resins and fly ash based zeolites for developing a cost effective technology for treatment of heavy metals, contaminated industrial waste water. Main toxic hazardous metal ions present in the various effluents are Fe, Cu, Pb, Al, Cr, Cd, Zn, Ni etc. Fly ash is byproduct of thermal power plants. This ash is waste for them so it is easily available & economy. Synthesis of zeolites from fly ash is a better way for utilization of waste fly ash for the effluent treatment.
