    • Value-Added Processing of Dairy Manure Using Vermicomposting 

      Dairy Environmental Systems (2003)
      Composting of livestock manure can significantly reduce odors, along with volume and weight. Using worms to further improve compost quality can add value in an energy-efficient manner and permit exporting of the vermicompost ...
    • Ventilation of Pre-Weaned Calf Barns: Part 1 Principles and Concepts 

      Bockhahn, Jennifer; Gooch, Curt (2018-11-19)
      Good calf barn ventilation is a significant contributor to the health and welfare of calves. Some diseases spread through the air, and inadequate air exchange rates can favor higher concentrations of pathogens. Therefore, ...
    • Ventilation of Pre-Weaned Calf Barns: Part 2 Overview of Methods 

      Bockhahn, Jennifer; Gooch, Curt (2018-11-19)
      Air exchange can be achieved through the use of natural ventilation, mechanical ventilation, or a combination of both commonly known as natural assist. All three types of ventilation systems require carefully designed air ...
    • What are the available technologies for biogas desulfurization? 

      Oliver, Jason P.; Gooch, Curt A. (2016-06)
      Biogas, a methane (CH4) rich gas produced from anaerobic digestion of organics, is a valuable renewable fuel. Upgrading biogas, the process of removing impurities and concentrating CH4, produces a cleaner, more useful/valuable ...
    • What are the current emission regulations for New York State? 

      Oliver, Jason P.; Gooch, Curt A. (2016-06)
      The seminal U.S. air quality statute, the Clean Air Act (CAA), authorized the U.S. Environmental Protection Agency (EPA) to protect public health and welfare by establishing National Ambient Air Quality Standards (NAAQS) ...
    • What are the potential emissions from engine-generation sets? 

      Oliver, Jason P.; Gooch, Curt A. (2016-06)
      Biogas is generated from anaerobic digestion of manure and organic wastes. It primarily consists of methane (50-70%), carbon dioxide (25-50%) and water vapor (1-5%). Depending on the feedstock and anaerobic digester ...
    • Whole-Farm Nutrient Management on Dairy Farms to Improve Profitability and Reduce Environmental Impacts 

      Cornell University; University of Wisconsin-Madison; USDA-Agricultural Research Service, Dairy Forage Research Center (2004-04)
      The National Center for Manure and Animal Waste Management determined that a large body of knowledge exists about livestock waste and nutrient management, but that the development and implementation of manure and animal ...
