  • vermiculture and waste management study of action of earthworms elsinia foetida eudrilus euginae and perionyx excavatus on biodegradation of some community wastes in india and australia
    The Environmentalist, 2002
    Co-Authors: Rajiv Kumar Sinha, Sunil Herat, Sunita Agarwal, Ravi Kumar Asadi, Emilio Carretero
    Abstract:

    The practice of vermiculture is at least a century old but it is now being revived worldwide with diverse ecological objectives such as waste management, soil detoxification and regeneration and sustainable agriculture. Earthworms act in the soil as aerators, grinders, crushers, chemical degraders and biological stimulators. They secrete enzymes, proteases, lipases, amylases, cellulases and chitinases which bring about rapid Biochemical Conversion of the cellulosic and the proteinaceous materials in the variety of organic wastes which originate from homes, gardens, dairies and farms. The process is odour free because earthworms release coelomic fluids in the decaying waste biomass which has anti-bacterial properties which kills pathogens. The species used in India were Indian blue (Perionyx excavatus), African night crawler (Eudrilus euginae) and the Tiger worm (Elsinia foetida). E. foetida was used in Australia. E. euginae was found to have higher feeding, growth and biodegradation capacity compared to other two species.

  • possibilities for sustainable biorefineries based on agricultural residues a case study of potential straw based ethanol production in sweden
    Applied Energy, 2013
    Co-Authors: Anna Ekman, Ola Wallberg, Elisabeth Joelsson, Pal Borjesson
    Abstract:

    This study presents a survey of the most important techno-economic factors for the implementation of biorefineries based on agricultural residues, in the form of straw, and Biochemical Conversion into ethanol and biogas, together with production of electricity and heat. The paper suggests locations where the necessary conditions can be met in Sweden. The requirements identified are regional availability of feedstock, the possibility to integrate with external heat sinks, appropriate process design and the scale of the plant. The scale of the plant should be adapted to the potential, regional, raw-material supply, but still be large enough to give economies of scale. The integration with heat sinks proved to be most important to achieve high energy-efficiency, but it was of somewhat less importance for the profitability. Development of pentose fermentation, leading to higher ethanol yields, was important to gain high profitability. Promising locations were identified in the county of Ostergotland where integration with an existing 1st generation ethanol plant and district heating systems (DHSs) is possible, and in the county of Skane where both a significant, potential straw supply and integration potential with DHSs are available.

  • compositional analysis of defatted syrup from a corn ethanol dry grind process as a feedstock for biobased products
    ACS Sustainable Chemistry & Engineering, 2014
    Co-Authors: Felix Adom, Jamie Davis, Paul Dunn, David R. Shonnard
    Abstract:

    A characterization study was conducted on defatted corn syrup (DCS) from an ethanol dry-grind process and its potential as feedstock for biobased products and biofuel is evaluated. Analyses included total solids, ash content, total protein, amino acids, inorganic elements, starch, total carbohydrates, lignin, organic acids, glycerol, and presence of functional groups. Total solids content was 37.4% (±0.4%) by weight, and the mass balance closure was 101 (±0.5%). Total carbohydrates [27% (±5%) wt of dry solids] were composed of starch (6.3%), soluble monomer carbohydrates (12%), and nonstarch carbohydrates (9.3%). Hemicellulose components (structural and nonstructural) were xylan (6%), xylose (1%), mannan (1%), mannose (0.4%), arabinan (1%), arabinose (0.4%), galatactan (3%), and galactose (0.4%). On the basis of measured physical and chemical components, a Biochemical Conversion route and subsequent fermentation to value-added products is a good possibility. Though less promising as a feedstock for liquid...

  • Compositional Analysis of Defatted Syrup from a Corn Ethanol Dry-Grind Process as a Feedstock for Biobased Products

On the basis of measured physical and chemical components, a Biochemical Conversion route and subsequent fermentation to value-added products is a good possibility. Though less promising as a feedstock for liquid transportation fuels, DCS has the potential to meet current United States demand (20–30 million kg per year) for succinic acid. Finally, even without any form of hydrolysis, DCS could also potentially meet global demand for histidine (360,000 kg per year)
