  • Estimation of Ascaris lumbricoides egg inactivation by free ammonia treatment of ash-amended UDDT vault products using stored urine in Uganda

    Urine-diverting dry toilets (UDDTs) are designed to recover nutrients and organic matter from human excreta for use as agricultural amendments, and have been promoted in many developing countries, including Uganda. Wider UDDT implementation could help address problems in areas where water scarcity limits sanitation coverage and/or declining soil fertility jeopardizes growing populations’ ...

  • A new way to measure emissions from China’s Coal-Fired Power Plants

    To prevent the most severe impacts of climate change, it is essential to limit fossil fuel use—particularly coal use in power production. The share of coal in global energy consumption is increasing, with ...

  • Application of radiomagnetiotelluric method case study

    Investigations of the landfill of industrial wastes by the RMT method The test site is the landfill of the coal ashes from power plants. The landfill was closed about 5 years ago. Material of the landfill is represented by powder-like particles and granules with the cross sizes from several millimeters up to the first centimeters. Wastes fill in a V-shaped valley of a stream (Fig. 1). The ...

  • Precipitator Solves Dryer Problem

    Plum Creek Manufacturing, Columbia Falls, Montana, installed a PPC Industries electrostatic precipitator to solve a direct fired dryer dust plugging problem. The electrostatic precipitator was installed in a very congested area and the project had to be done so the dryer was off-line a minimal amount of time. Plum Creek personnel relocated existing equipment, poured concrete footings, ran all of ...

  • Condensed matter nuclear science (cold fusion): an update

    Seventeen years after the announcement by Professors Stanley Pons and Martin Fleischmann of the discovery of cold fusion in March 1989, the scientific community does not acknowledge this field as a genuine scientific research theme. However, the scientific demonstration of cold fusion was made long ago by showing the evidence of excess heat production in electrolytic cells and other devices. ...

  • Radionuclide content of human samples in the Ramsar area of Iran

    As part of a survey to determine public exposure to natural radiation and to estimate radionuclide levels in the diet and human tissues, the radionuclide content of different biological samples of residents in Ramsar, a high level background radiation area (HLBRA) in Iran, has been measured. The main route of 210Po and 210Pb intake in the human body is ingestion ...

  • Pathogen destruction and solids decomposition in composting latrines: study of fundamental mechanisms and user operation in rural Panama

    The relationship between temperature, high pH, desiccation, decomposition, pathogen destruction, and user operation in active double vault urine diverting (DVUD) composting latrines located in the Bocas del Toro region of Panama was assessed. Latrine samples were analyzed for temperature, pH, % moisture, carbon-to-nitrogen (C/N) ratio, and presence of specific pathogens. Surveys and visual ...

  • Cemex plant Ruedersdorf - Case Study

    CEMEX Deutschland AG is one of the biggest producers of ready-mixed-concrete, cement and minerals. In Germany CEMEX employs a staff of approximately 3,200 people and is part of the International CEMEX Group with a head count of 50,000. After the German re-unification the Company acquired the existing cement plant in Ruedersdorf. Investments to save CEMEX invested ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • MSW Thermovalorization

    The problem of waste elimination has been a topical subject in the last decade due to the growing use of throwaway products and packaging, that make up 40% of the entire waste by now. In Italy more than 25 million tons of municipal solid waste  are produced every year. On average, every inhabitants in our country produce about 450 kg of waste per year, more than one kilogram per day.  Until the ...

  • Upstream Particulate Removal for Rtos on Direct-Fired Osb Dryers – How much is enough?

    Abstract Since 1994 Regenerative Thermal Oxidizers (RTOs) have been applied to direct wood-fired OSB dryers for the purpose of VOC abatement. In early direct wood-fired OSB dryer applications many OSB producers felt that upstream particulate control was not necessary. However, the ash from the combustion of wood waste created a host of new operational problems for the RTO systems. This paper ...
