Title

Ethanol, Plastics and Butadiene from Forestry Biomass via Optimum Production System

Abstract

Presently, the desire to reduce import and raise balance of trade, and the need to mitigate problems of petroleum consumption like CO2 emission and global warming, is driving nations into seeking renewable and sustainable alternatives. In this work, optimized pr-oduction system from robust comparison is used to estimate the potential of forestry waste woody biomass for bioproducts worldwi-de and in Europe. Bioproducts considered are bioethanol for fuel, plastics (polyethylene, polypropylene, polyvinylchloride, polystyre-ne, polyethylene-terephthalate) for material, and butadiene for che-mical. Chemical synthesis, syngas fermentation, direct fermentation and carboxylate routes to products were investigated. Smart utiliza-tion increased pro-duction over a number of conversion routes. Opt-imum utilization patterns compared to when whole biomass is used directly through (i) thermochemical route gave 16.7% increase in production (ii) biochemical route provid-es 33.3% increase in prod-uction which represent significant savings for the biorefinery. It was found that while 52.7% and 71.9% of feedstock is required to sa-tisfy demand for plastics worldwide and Europe respectively and 2.7% and 4.5% of biomass worldwide and in Europe respectively is the feedstock level required to replace petroleum based butadiene production, meeting 40% and 48.4% of gasoline energy demand worldwide and in Europe respectively completely deplete this biom-ass resource.

Title

Biodiversity of Ants (Insecta-Hymenoptera) in Agro-Ecosystem and Grass Land in Jammikunta, Karimnagar District, Telangana, India

Abstract

Ants are most numerically abundant group of social insects. They are ground or litter dwelling predators or scavengers. Diversity of ants in agro-ecosystem and grassland was investigated during June 2012 to May-2013. Ant species collected monthly using pitfall traps and hand picking methods. A total of 30 ant species belonging to 18 species of Myrmicinae, 8 species of Formicinae, 2 species of Poneri-nae and 2 species Dolichoderinae were recorded. Shannon-Wieners diversity (H), Evenness (J) and Species richness (S) for different mo-nths were calculated.

Title

Study of Ground Water Quality of Cuttack City, Odisha, India Using Water Quality Index

Abstract

Water Quality Index (WQI) has been applied in the present study to assess the suitability of ground water for drinking purposes in Cutt-ack City of Odisha State, India. This was carried out by subjecting 21 groundwater samples collected from seven selected sites. Analys-is was done for physico-chemical and microbiological parameters. Eight  parameters (except (TC and FC) (Total Coli form and Faecal Coli form respectively) have been considered for calculating the WQI such as pH, Turbidity, Conductivity, Total Hardness, Chloride, Total Dissolved Solid, Iron, Fluoride. WQI has been found below 50 (WQI <50) in bus stand area and Kalyani Nagar area. In Baramun-da and near S.C.B. Medical College, WQI was 50-10. In Khapuria industrial area and in Pattapolo area, WQI was found to be 100-200. In C.D.A. area WQI exceeds 200. The higher values of WQI at this site have been found mainly due to higher values of Fe, TDS, TH and conductivity. Corelation studies show Conductivity, TH, Cl-, TDS are highly co-related to each other.
