  • Air emissions of ammonia and methane from livestock operations: Valuation and policy options

    The animal husbandry industry is a major emitter of ammonia (NH3), which is a precursor of fine particulate matter (PM2.5) —arguably, the number-one environment-related public health threat facing the nation. The industry is also a major emitter of methane (CH4), which is an important greenhouse gas (GHG). We present an integrated process model of the engineering economics of technologies to ...

  • Pilot scale facility to determine gaseous emissions from livestock slurry during storage

    Livestock production is a growing source of air pollution, locally and to the wider environment. Improved livestock manure management has the potential to reduce environmental impacts, but there is a need for methodologies to precisely quantify emissions. This paper describes and evaluates a novel storage facility for livestock slurry consisting of eight 6.5-m3 cylindrical units. The stores may ...

  • Characterization of microbial communities in exhaust air treatment systems of large-scale pig housing facilities

    Exhaust air treatment has gained importance as an essential factor in intensive livestock areas due to the rising emissions in the environment. Wet filter walls of multi-stage exhaust air treatment systems precipitate gaseous ammonia and dust particles from exhaust air in washing water. Microbial communities in the biomass developed in the washing water of five large-scale exhaust air treatment ...

  • Main Applications of Truck Mounted ULV Fogger

    A fogger is a machine which distributes chemicals such as insecticide or disinfectant into an area by means of a fine spray for killing insects and other arthropods. They are often used by consumers as a low-cost alternative to professional pest control services. The number of fogger needed for pest control depends on the size of the space needed to treat. There are different types of ...

  • Surprising ways Kenyans are embracing climate-smart agriculture

    In rural Kenya, where it may only rain twice per year, farmers and herders are embracing so-called “climate-smart” agriculture. The video above, produced by the World Bank, begins by showing how John and Mary Obuom have transformed their one-acre farm into a model of sustainable practices. The family plants a diversity of crops in case one or more fails in a given year. A thicket of ...

  • Chicken waste could produce unexpected energy windfalls in Ukraine

    Ukrainians soon could enjoy a new windfall of electricity and heat from an unexpected source – chickens. In some unusual news, the Swiss company Alter Energy Group AG is assessing Ukrainian poultry farm sites to implement a sophisticated waste to energy process. The process takes chicken and poultry manure and turns it into clean, environmentally safe, industrial scale electricity and heat. This ...

  • EMSL expands often overlooked mycotoxin testing services due to demand

    Are there Mycotoxins in your air or food? Mycotoxins can be produced by fungi growing on crops during field or storage conditions and on damp building materials. Emerging research indicates that exposure to mycotoxins may lead to a variety of health effects. Some of the more common exposures can be traced to ingestion of contaminated foods and feed. Examples of contaminated food ingredients ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • Dutch Farmers Find It Pays To Manage Poultry Manure

    Poultry farmers in Holland face challenges similar to their North American counterparts in dealing with manure from concentrated operations where there is insufficient cropland for application. This creates a need for exporting manure from the producing farm to users in other places. Poultry operations in Holland differ from most North American poultry farms in that most are not vertically ...

  • Latest Progress in Anaerobic Digestion

    Compared to countries like Germany and Denmark, the United States and Canada have a long way to go in creating the fundamental policy incentives and regulatory mandates that will encourage market development for anaerobic digestion (AD). Someone recently asked me how many years it would take to deploy AD systems on farms in North America that are large enough to economically use them. Given ...

  • Ohio Takes Aim At Food Waste Composting

    WHILE RECYCLING of paper and yard trimmings have grown rapidly in Ohio in the last 30 years - now up to 50 percent for paper and 62 percent for green materials, the recovery rate for food residuals is at less than three percent of nearly 96 million tons generated annually. To turn things around, the Ohio EPA and its Solid Waste Management Division have teamed up to get the word out about ...
