  • In-situ estimation of the methane generation rate for a wet and highly organic solid waste landfill

    Significant investments in landfill gas utilisation projects are required at project commencement. The methane generation rate for the Villa Dominico Landfill in Buenos Aires, Argentina is 0.26 yr−1, a very high rate as a result of the high organic content in the waste, and high moisture conditions within the refuse. The implications for landfills is that ...

  • Influence of the comminution of organic waste on their biodegradability

    Organic solids are present in very large quantities as products or waste from agriculture, food industry, household and many other fields. The disposal of organic waste can be realised using biological processes like anaerobic digestion or aerobic composting. The anaerobic digestion has advantages in comparison to composting such as a better handling of wet waste, the production of useful ...

  • Development of wet pre-treatment and pulper technology

    Since 1984 BTA is involved in activities in the area of waste pre-treatment. This process was first implemented in 1986 in a pilot plant. The patented BTA-Process is consisting of the following main steps: - Wet pre-treatment of waste with separation of the contaminants and production of a pumpable suspension- Sand separation by a hydrodynamic grit removal system- Digestion of the suspension in ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • Home composting of organic waste - part 2: effect of management practices

    Home composting (HC) can produce safe compost if properly managed, while reducing municipal disposal costs. This project investigated the sanitary and safety impact of HC management (with/without bulking agent, batch/weekly feeding, with/without regular mixing) using the Plastic (P) and Wood (W) bins, the Rotary Drum (RD) and the Ground Pile (GP) filled with equal wet volumes of food waste (FW) ...

  • Contaminant removal from dry and wet sands by thermal desorption

    Infrared heating was used to determine the effects of temperature and moisture on the removal of selected organic compounds from contaminated sand matrices. Quartz sand was used as a chemically inert surrogate for soil to isolate the heat transfer and mass transfer effects without any chemical contribution from soil. The selected organic contaminants were 3-nitrobenzene sulphonic acid, sodium ...

  • Decomposition of major organic components during mechanical-biological pretreatment of residual municipal solid waste

    Landfilling of untreated municipal solid waste (MSW) generates environmentally hazardous gas and leachate emissions (El-Fadel et al., 1997). The aim of mechanical-biological waste pretreatment (MBP) is to anticipate this process in a controlled system and to avoid later emissions in the landfill (Leikam and Stegmann, 1997). Main source of these emissions is the microbial metabolism of the easily ...

  • Waste not in Asheville

    Asheville, North Carolina, has gained a national reputation as a hub of local and artisanal foods. In fact, the local foods movement in this Southern Appalachian city has become so embedded in the community consciousness that the city has dubbed itself “the world’s first Foodtopian Society.” There are hundreds of unique restaurants, dozens of bakeries, breweries and ...

  • Treatment of Alkali-Pretreated Slurry of Organic Fractions of Municipal Solid Waste using Upflow Anaerobic Sludge Blanket (UASB) Reactor

    [Master's Thesis in Environmental Engineering] As an alternative technology for use of local governments, we propose to demonstrate the suitability of anaerobic digestion (AD) system to treat the organic fractions of municipal solid waste (OFMSW). To enhance the process, we applied several pre-treatment steps: comminution, extraction, and addition of sodium hydroxide to achieve the desired pH ...


  • Co-digestion - Processes, potentials and organization Forms

    Co-digestion of organic wastes together with livestock manure has received growing interest in Germany during the last 5 years because some waste acts have been changed in order to achieve a better protection of the environment and to promote the utilisation of wastes for the formation of renewable energy and secondary products which can substitute mineral fertilisers and conventional soil ...

  • 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 ...

  • Enzyme Activities and Chemical Changes in Wet Olive Cake after Treatment with Pleurotus ostreatus or Eisenia fetida

    Abstract  A laboratory experiment was conducted to evaluate the enzyme activities and chemical changes recorded in a recalcitrant phenolic-rich waste after treatment with Pleurotus ostreatus or Eisenia fetida. The waste used was wet olive cake (alperujo in Spanish), a waste produced in huge amounts by the olive oil industry. Both P. ostreatus and E. fetida were very effective in removing ...


  • Reclamation of a mine contaminated soil using biologically reactive organic matrices

    Organic residues such as sewage sludge, biowastes and composts are increasingly used in land rehabilitation because they can improve the physical, chemical and biochemical properties of soil, and reduce the need for inorganic fertilization. Furthermore, their use contributes to an integrated approach to waste management by promoting recycling of nutrients and minimizing final disposal, especially ...
