Abstract: This paper summarizes a groundwork investigation of production of Bio-Ethanol from Sugarcane and analysis of its feasibility in terms of social, economic and environmental aspects. The main objective of this case study is to analyze the option available for ethanol production from sugarcane. As the disposal of sugar mill biomass (bagasse) is a major issue concern for environment, we also suggest the ways to efficiently use bagasse to produce steam and electricity – a sustainable solution of clean energy. Production of Bio-Ethanol is result of several steps of Extraction, Fermentation, Distillation & Dehydration and we demonstrate a comparison of production of Bio-Ethanol from Bagasse and Molasses. In addition, preliminary analysis shows greater scope for more clean and green technology for the still grey areas.

Abstract: A simple, accurate and precise UV-spectrophotometric method based inverse least-squares was developed for the simultaneous determination of atorvastatin and amlodipine in tablet formulation. The absorbance values of the two analytes were linear with the concentration at the wavelengths taken at 5 nm interval over the range of 230 -260 nm. The calibration equations were developed using the absorbance values of nine synthetic mixtures containing different concentrations of two analytes measured at 5 nm intervalsin the range of 230 -260 nm. The developed equations werethen validated by calculating the analytes recovery from the analysis of a set of another five synthetic mixtures, the mean% recoveries were 100.02% and 100.06% with the corresponding% RSD of ±0.36 and±0.51 for atorvastatin and amlodipine, respectively. The calibration equations obtained were then used to obtain the concentration of each analyte in commercial samples. The mean % recoveries were 100.43% and 100.28% with the corresponding% RSD of ±0.78 and±0.85 for atorvastatin and amlodipine, respectively. The validity of the proposed method was confirmed through the statistical comparison of the obtained results with those obtained by a reference method utilizing high performance liquid chromatography for the determination of the two actives, the calculated t-values at (P=0.05, n =6) were 1.47 and 0.73 compared to the tabulated value of 2.23.
