  • Poul-AR Valorization of poultry manure - Fertilizer and energy from poultry manure

    Application In contrast with generic manure types, poultry manure is very rich in nutrients as nitrogen (N) & phosphorus (P), but also in organic material. Both the form and the N/P ratio in which the nutrients are present make the manure less suitable for direct application as natural fertilizer. It leads to the release of large and undesired amounts of volatile ammonia into the ...

  • Biocontained mortality compost using liquid manure

    During disease outbreaks, composting has been used to safely dispose of carcasses and infectious solid manure. However, optimized methods have not been established to use liquid manure (> 80% water content, WC) from dairies as the substrate for mortality composting. In April of 2007, a 3x2 factorial study was conducted in wooden compost bins (240 x 240 x 140 cm) lined with 0.5 mm plastic to a ...

  • 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 ...

  • Animal Manure or Sludge Organic Fertilizer Production

    Introduction of Animal Manure or Sludge Organic Fertilizer Production Line Organic fertilizer production line is designed for producing organic fertilizer from animal manure or sludge, without any chemical ingredients. As chickens, pigs have a poor digestion, can only consume 25% of the nutrients, so other 75% of feed nutrients with feces discharge can be produced to the dry ...

  • A biosecure composting system for disposal of cattle carcasses and manure following infectious disease outbreak

    Received for publication April 11, 2008. During outbreaks of infectious animal diseases, composting may be an effective method of disposing of mortalities and potentially contaminated manure. Duplicate biosecure structures containing 16 cattle (Bos taurus) mortalities (343 kg average weight) were constructed with carcasses placed on a 40-cm straw layer and overlaid with 160 cm of feedlot manure. ...

  • Formation and emissions of ammonia and greenhouse gases from stored and composted solid animal manure

    Beside other branches of industry, agriculture is an important source of methane (CH4) and nitrous oxide (N2O) emissions and the most important source of ammonia (NH3). In spite of several investigations concerning ammonia and greenhouse gas emissions during storage and composting of liquid and solid animal manure, the real extent of these emissions is still unknown. This is mainly because of the ...

  • Nutrient Management: Recycling Residuals Into Animal Feed

     Composting Reduces Fuel and Labor Costs on Family Farms Jeff and Pam Riesgraf — who manage a certified organic dairy and crop operation near Jordan, Minnesota — began composting manure from their dairy herd in 1993. They had two major objectives. First, they wanted to reduce weed seeds naturally present in manure. At the same time, they understood the need to protect water quality by ...

  • 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 ...

  • 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 ...

  • Industry Takes Shape: Why Digesters Make Dollar Sense Now

     THIRTY years ago, when I was a college student studying ways to convert manure to electricity, we speculated that the 1970s would be the decade of the innovators, the 1980s for the launch of operating projects, and the 1990s when the mainstream adopted the technology. Now I think our predictions for the mainstream were ten to 15 years premature — but it is happening! During the 1990s, the ...

  • A `classic` for agriculture - case study

    A 500 kW-Biogas plant (typical to its kind in every regard) is located in Gehlenberg. There, 500 kW were legally defined as the permissible maximum limit value for agricultural operations. In Gehlenberg, the competent consulting services provided by bwe attracted particularly positive attention. After all, the plant (operational since 2006) is impressive in its high degree of overall efficacy and ...

  • Independent review of retrofitting Cambi to mad

    ABSTRACT Denmark has taken a very positive view of recovering energy from organic wastes by anaerobic digestion (AD) and then using  the digestate (digested material) on land. Substituting CHP (combined heat and power) from AD for fossil energy is part of  the national energy plan. Co-digestion of manure, putrescible waste and biosolids is becoming increasingly common. Part of  ...

  • Solid thickening and methane production of livestock wastewater using dissolved carbon dioxide flotation

    Dilute manure is classified as wastewater due to the large quantity of water used in livestock production in Korea. Livestock wastewater treatment is required in order to reduce high moisture content and treat fluids discharged from the digestion process. In livestock wastewater treatment plants, large quantities of CO2 gas are produced at combined heat and power facilities as well as in the ...

  • 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 ...
