  • Utilisation of waste in integrated sugar distillery industry with special reference to bio-energy generation: a case study

    Sugar and distillery industries, though being agro-based industries, still have potential towards contribution of a large number of pollutants. Sugar industry generates molasses, bagasse and press mud apart from emission to the atmosphere. Press mud and bagasse are the two major types of solid waste requiring special attention. But, as a matter of fact if sugar and distillery industry is operated ...

  • Anaerobic digestion of post-hydrothermal liquefaction wastewater for improved energy efficiency of hydrothermal bioenergy processes

    Hydrothermal liquefaction (HTL) is a promising process for converting wet biomass and organic wastes into bio-crude oil. It also produces an aqueous product referred to as post-hydrothermal liquefaction wastewater (PHWW) containing up to 40% of the original feedstock carbon, which reduces the overall energy efficiency of the HTL process. This study investigated the feasibility of using ...

  • Focus Bioenergy No 6 2004: Waste - a source of energy of growing significance

    We have to use the earth’s resources sparingly. Waste products that society generates can be recycled or used as a source of energy. Heat and electricity from waste combustion and biogas from digestion contribute some 8 TWh annually in Sweden. Waste stands for about 2 percent of used fuels in Swedish district heating. The importance of waste will rise rapidly in the near future. The ...

  • Using wastewater and high-rate algal ponds for nutrient removal and the production of bioenergy and biofuels

    This paper projects a positive outcome for large-scale algal biofuel and energy production when wastewater treatment is the primary goal. Such a view arises partly from a recent change in emphasis in wastewater treatment technology, from simply oxidising the organic matter in the waste (i.e. removing the biological oxygen demand) to removing the nutrients – specifically nitrogen and ...

  • Biomass and Integration in Future Energy Systems and the Bioeconomy

    Biomass was the primary source of materials and energy until the industrial revolution set off a series of major changes around two hundred years ago. In the industrialized world fossil fuels became the primary source for energy in the forms of electricity and heat and provided almost all fuels for transport. However, biomass continued to maintain an important role in the economies in both ...

  • Commericalizing cellulosic ethanol

    Cellulosic biofuels, produced from nonfood feedstock, are expected to play a critical role in reducing the country's dependence on imported oil. EISA, the Energy Independence and Security Act of 2007, calls for the production of 100 million gallons per year (mgpy) of cellulosic biofuels by 2010, with a longer term goal of 16 billion gallons by 2022.Achieving these goals will not be easy. Several ...
