  • Farm digesters for small dairies in Vermont

    THROUGH its award-winning Cow Power program, Central Vermont Public Service (CVPS), a Vermont utility headquartered in the city of Rutland, is helping dairy farmers diversify their incomes by turning manure into electricity. The farmers process manure in anaerobic digesters to generate power, which CVPS customers voluntarily pay a premium to purchase. In addition to income from electricity sales, ...

  • Application of artificial neural network to model the energy output of dairy farms in Iran

    An artificial neural network (ANN) model was developed to assess the energy input–output prediction in dairy farms of Iran. Data used were culled from 50 randomly selected farms using face to face questionnaire approach. The energy input–output analysis was carried out for the parameters of ANN model. Based on performance measures, single hidden layers with 16 neurons in the hidden ...

  • Operationalising eco-efficiency in agriculture: the example of specialised dairy farms in Flanders

    Eco-efficiencies of a representative set of Flemish dairy farms were determined for the years 19891990 and 20002001. Eco-efficiency was measured as a combination of nitrogen (N) use efficiency and energy use efficiency, where N use efficiency (l milk kg-1 N surplus) is the ratio between the amount of produced milk and the farm-gate N surplus (= N input − N output). Energy use efficiency (l milk ...

  • Californias Dairies have more anaerobic funds

    Producers must be able to sell excess electricity and have markets for that power if projects are to be viable, says the CEO of Western United Resource Development. APPLICATIONS are now available for funding construction of anaerobic digestion systems on California dairies. The California Energy Commission has funds of $2.3 million provided through the Dairy Power Production Program (DPPP). To ...

  • Farm digester progress in Pennsylvania

    The Commonwealth of Pennsylvania is home to about 7,000 dairy farms with an average herd size of less than 100 cows. While nutrient and odor management are of great importance to these farms, their overall economic viability appears to be the primary factor driving installation of anaerobic digesters over the past few years. “Pennsylvania has 30 dairy digesters and about 5 swine digesters ...

  • Adding Value To On-Farm Digesters

    ANAEROBIC digestion of dairy manure and food processing residuals in Michigan is not a new undertaking. Over the years, 11 farm digesters were constructed in the state, of which four are still operational, reports Michelle Crook of the Michigan Department of Agriculture in a presentation in the spring of 2007. “Three of the operating digesters are for livestock manure and one is for food ...

  • Farm digester evolution in Vermont

    In the fall of 2012, Brian Jones of Joneslan Farm in Hyde Park, Vermont spread the first load of manure that had gone through the farm’s new anaerobic digester. “It didn’t smell at all,” recalls Jones. “And we’ve been told that the nitrogen in the digested manure is more available to the plants we grow.” When the Joneslan Farm digester went on line in ...

  • Environmental input–output analysis of the New Zealand dairy industry

    This work presents data and analysis quantifying the total (direct and indirect) resource use and outputs (products and pollutants) of the New Zealand dairy industry for the year April 1997 to March 1998. It also identifies those sectors supplying the dairy industry which make significant indirect contributions to its total inputs and outputs. Although this data is 14 years old, it is the only ...

  • Environmental and Economic Perspectives of Milk Production in Feedlot and Grazing Systems

    Abstract Dairy production systems involve large inputs and large outputs. In environmental and economic terms, this means dairying is potentially a large consumer of natural resources and a generator of large amounts of pollutants and waste as green house gases (GHG) and manure. To ensure a sustainable milk production system; it becomes important to understand the environmental and ...

  • 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 ...

  • Supply- and demand-side management of water in Gujarat, India: what can we learn?

    Agriculture in Gujarat has grown rapidly over the last decade, driven at least partly by diversification to high value crops and dairying. High value agriculture requires better water control and offers higher returns for irrigation. Farmers, farm communities and the state government in Gujarat have responded to this requirement by implementing large-scale water supply and demand management ...
