  • Performance analysis of a co-gasifier for organic waste in agriculture

    Background:Agricultural waste has been proposed as an alternative energy resource to meet fossil fuel crisis, green house emission, and other environmental impacts worldwide. In Iran, rice husk and bagasse are main resources of biomass which can be used to produce syngas. This paper deals with a simplified model of combined gasification of coal and biomass processes considering chemical ...

  • High performance biogas plants for organics waste diversion

    Wild fluctuations in prices for agricultural products and mushrooming prices for energy can greatly influence the economics of biogas plants. Long term reliable profitability calculations are becoming increasingly difficult. Generally speaking, however, rising energy prices have a positive effect on the economics of well designed biogas projects. By selecting low cost feedstock, the profitability ...

  • What is Biomass Pellets Energy

    Biomass pellets energy means the energy made from biomass. What is biomass? Biomass refers to all the organic matters that store energy from photosynthesis. Therefore biomass in most cases means plants instead of animal. What is the chemical composition of biomass? Biomass is carbon based, so it contains ...

  • Status and trends for biomass use and consequences for waste management - the example of Germany

    While separate collection and treatment of organic waste in Germany had a magnitude of 100.000 Mg in 1985 it currently extends to 8.2 Mio. Mg of which about 50% each refers to biowaste and green waste respectively. However, a further potential of 8 million Mg of organic waste collected with other residual waste still exists. Rapidly increasing costs for the treatment of residual waste coupled ...

  • Biomass energy outlook

    Over the last three or four weeks, my newsletter, Burning Bio News, has been oddly extreme. Timothy Searchinger, Princeton University, is churning out more antibiofuel hearsay. Dennis Avery, Hudson Institute, was in the news again putting a counter-spin on climate change. The U.S.EPA released its proposed rule for regulation of Greenhouse Gases (GHG) that includes industrial facilities that emit ...

  • Removal of arsenic from an aqueous solution by pretreated waste tea fungal biomass

    Arsenic exists in natural waters both in inorganic and organic forms. The inorganic form of arsenic is more toxic compared to its organic form. Inorganic arsenic is the predominant form in contaminated groundwater. Arsenic exists in two,oxidation states: arsenite, As (III) and arsenate, As (V) (Pokhrel and Viraraghavan, 2006). It is introduced in the aqueous system through geochemical reactions ...

  • Potential of hydrogen production from organic Urban Solid Waste fermentation in Mexico

    Mexico generated 35.4 million tons of urban solid wastes in 2005 of which 51% were organic ones. This biomass can be fermented into H2 when H2-based technologies increase their market penetration for the year 2020. The purpose of this work was to review studies that have utilised organic solid wastes for fermentative H2 production and to evaluate the potential for Mexico. The experimental H2 ...

  • Application of different organic wastes on soil properties and wheat yield

    Fresh and composted organic wastes [beet vinasse (BV), sewage sludge (SS), and a cotton gin crushed compost (CCGC)], were applied for 4 yr to a Typic Xerofluvent in dryland conditions near Seville, Spain. Organic wastes were applied at rates of 5, 7.5, and 10 Mg organic matter ha–1, respectively. The effect on the soil's physical properties, soil microbial biomass, and six soil enzymatic ...

  • Ethanol, Biomass Plants Planned for Minnesota

    Proposed facilities prepare to turn organic residuals into electricity, methane and synthesis gas “with minimal emissions and more profit.” AN ETHANOL plant in Little Falls, Minnesota is building an on-site gasifier that will convert wood waste and distiller's grains to gas for generating electricity and heat to serve the needs of the Central Minnesota Ethanol Cooperative. At the same time, ...

  • Relative efficacy of two methods of vermicomposting for bio-degradation of organic wastes

    Two methods of vermicomposting were used for the bio-degradation of organic wastes, viz., the pit method and the heap method. The efficacy of these two methods was compared under field conditions over three seasons (winter, summer and rainy) by using one of the most promising composting worm species, Eisenia fetida. One hundred adult earthworms (Eisenia fetida) were released in each pit and heap. ...

  • Woody Biomass as renewable energy source

    In-depth analysis in Minnesota assesses the feasibility and cost-effectiveness of regional biomass generated electricity projects that tap into local feedstocks. The Center for Energy and Environment (CEE) in Minneapolis, Minnesota undertook a multiphase research project to create a framework that communities and legislators can use to determine the feasibility of biomass-generated electricity in ...

  • Pumps with extended service life for generating biogas from organic waste

    When regular commercial pumps are used to process organic waste, they typically wear out after only a short period of time. Liquids pumped under these conditions attack pumps from two different angles: first with highly abrasive additives and second with liquids that have highly fluctuating pH values and therefore a high level of chemical aggressiveness. These conditions are very tough on seals ...

  • Anaerobic digestion of waste biomass from the production of L-cystine in suspended-growth bioreactors

    Waste biomass from the industrial production of the amino acid L-cystine contains above-average concentrations of organic pollutants and significant concentrations of nitrogen and sulfur. The specific biogas production (SBP) of waste biomass was monitored in parallel suspended-growth laboratory anaerobic bioreactors. After severe inhibition was observed, three different procedures were applied ...

  • Impact of organic residues on soil microorganisms

    It is well known that organic residue amendments to soil give beneficial effects such as provision of plant nutrients, increased humus content and thereby increased water holding capacity, improved structure and increased cation exchange capacity. Organic wastes can be a valuable fertiliser in terms of phosphorous. Chemical precipitation in the sewage treatment plant makes sewage sludge rich in ...
