The Bioremediation is green technique that reduces contaminates & nutrient from sewage water. The sewage under the influence of Eichhornia & Pistia species for twenty days shows a significant change in the concentration of impurities. The change was observed by Physico-chemical, Nutrients, Microbial Factors & Solid analysis with different interval of days. The percentage of nutrients and other parameters absorbed by Eichhornia was better than Pistia. The level of impurities was reduced by the remarkable amount by activated charcoal & alum treatment.

Indian Rubber Industry plays a core sector role in the Indian national economy. Globally, it is estimated that 13.5 million tonnes of tyres are scrapped every year; 40% of which come from emerging markets such as China, India, South America, Southeast Asia, South Africa and Eastern Europe. In the US alone, exports of waste tyres amounted to almost 140,000 tonnes/year from 2002-2011. Figure 1 shows that the latest estimates of the scrap tyre distribution in the world.

India and China, these waste tyres are not evaluated properly. One of the thermal processes is pyrolysis that
waste tyres can be converted into gas, oil and solid product. Scrap tyres do not decompose easily in the
nature and cause too many environmental problems. The carbon black obtained from pyrolysis of scrap
tyres at a temperature of 500°C contains 11-12 % ash. Due to the presence of high ash content limits its
application in different products. The pyrolytic carbon black obtained (CB) was contaminated by various
additives of the original tire. Contaminants were also produced by chemical reactions occurring in the
pyrolysis reactor. A characterization and demineralization of the recovered carbon black was performed
and a possible reduction of the ash content by H2SO4, HCl, HNO3 and NaOH treatment was investigated.
The variables which were studied included the ratio of reactant to carbon black, the reactant concentration,
the treatment temperature and the reaction time. As a conclusion, the improvement studies had a positive
effect to decrease ash content of solid products. It was found that treatment of a mixture of acids is very
effective than individual.

Biodiesel is a more attractive product from sapodilla seed oil to diesel engines, because of seeds are chiefly available and non-edible to all human being. Since most of the biodiesel were derived from edible oils like soybean, sunflower, rapeseed, palm etc. these oils are essentially edible in India and other developing countries and use in biodiesel leads to food crisis. Because of the non-edible oil having high free fatty acid(FFA) content, which is not suitable for normal transesterification process, hence a two-step catalyzed method i.e. acid catalyzed method followed by alkali catalyzed, was used to prepare the biodiesel. For this study the sapodilla seed oil was used to extract the biodiesel. Therefore, this research mainly concentrates the non-edible oil as a feed stock for biodiesel production to reduce the cost of biodiesel.

The effluents of these industries produces verity of pollution in in nearby sewers & rivers. The remediation of dye effluent after twenty days under the influence of Eichhornia & Pistia species shows the significant change in the concentration of impurities. The change is observed by the analysis of Physico-chemical parameters, Nutrients, Microbial Factors & Solid parameters of treated & untreated dye effluents with different interval of days. The concentration of sodium gives amazing results in both plants for dye effluents. The plants are analyzed for percentage of NPK, which shows significant results for Eichhornia species. The percentage of nutrients absorbed by Eichhornia species shows better results than Pistia species. The degradation of dye effluents by using two ways affects on the concentration of all impurities.

The results obtained were compared with WHO and EPA standards for drinking and recreational water. pH is within the permissible limit & values are close to each other. Conductance &
Alkalinity are high value for Bhorkudfalia & Baldevi sample which indicate that the presence of Bicarbonate, carbonate, Ca, Mg, Cl-, Na+, K+ ions are in high amount. DO, BOD, and COD
of Bhorkudfalia & Naroli show the high values of this parameter indicate heavy bacterial growth. Total Coliform clearly indicates that water from all area is not potable. This water contains
bacteria which spread epidemic diseases. TS, TDS, TSS, and Turbidity values from Tokarkhada, Hathola & Naroli are more than permissible limit. This indicates heavy pollution in these
areas. The presence of pathogens in water for drinking and swimming purposes is considering the possibility of the presence of other bacteria, protozoa and enteric viruses. This worried in gastrointestinal
water borne diseases and the low infectious dose for these water borne pathogens.
