  • 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 ...

  • 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 ...

  • The role of constructed wetlands for biomass production within the water-soil-waste nexus

    The use of constructed wetlands for water pollution control has a long standing tradition in urban, peri-urban, rural, agricultural and mining environments. The capacity of wetland plants to take up nutrients and to filter organic matter has been widely discussed and presented in diverse fora and published in hundreds of articles. In an ever increasingly complex global world, constructed ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Nitrogen removal in maturation waste stabilisation ponds via biological uptake and sedimentation of dead biomass

    In this work a set of experiments was undertaken in a pilot-scale WSP system to determine the importance of organic nitrogen sedimentation on ammonium and total nitrogen removals in maturation ponds and its seasonal variation under British weather conditions, from September 2004 to May 2007. The nitrogen content in collected sediment samples varied from 4.17% to 6.78% (dry weight) and calculated ...

  • Effect of tertiary combinations of animal dung with agrowastes on the growth and development of earthworm Eisenia fetida during organic waste manageme

    Background Abundant uses of chemical fertilizers have adversely affected the soil. The large production of livestock dung is recorded in India annually. The presence of abundant agrowastes and animal dung causes serious problems to animals as well as to human beings, due to the improper management of these wastes. Due to the presence of different physicochemical parameters, these agrowastes and ...

  • The Right Forces · Producing Power from Recycled Organics

  • Organics recovery expands in Wyoming`s tetons

    THE TOWN of Jackson, Wyoming is located in a glacial valley, originally referred to as Jackson's Hole by the fur trappers and game hunters who came down out of the mountains to rendezvous and sell their goods for shipment to markets back east. Today, elk and bison spend winter on the National Elk Refuge, its fence line abutting the town of Jackson, where they are fed and protected until they ...
