  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Filter manure slurries directly before, after, or in place of anearobic digesters with a reverse osmosis VSEP membrane system, providing potable water for the animals and a concentrated nutrient feedstock for fertilizer.

    If constructed and managed properly, the age-old lagoon method of manure handling is a reliable method of storing and treating livestock waste. Lagoon storage followed by sprayfield application on local farms has proven to be a very symbiotic and effective method throughout the ages. However, the recent trend in the hog production and the cattle industry is towards larger centralized operations ...

  • 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 ...

  • Anaerobic Digestion at Dairy Farms

    The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites. The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of ...

  • 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 ...

  • Case Study - Manure Magic

    Manure Magic is a patented product that can help support successful manure management programs throughout the world, such as field applications as fertilizer, because of its ability to liquefy the manure, which makes it much easier to administer. Application Examples The increase in regulatory requirements in dealing with animal waste solids has required growers to closely ...

  • Entrepreneur Connects Generators To AD

    A Northeast company brings anaerobic digestion and renewable energy to the feedstock sources in Ohio and New York State. Western New York is one of the top dairy-producing regions in the U.S. The by-products of making milk, cream, yogurt and other dairy products have certain characteristics that make them ideal fuel for anaerobic digesters designed to produce methane gas for the ...

  • Ohio Targets Food Residuals Composting

    WHILE RECYCLING of paper and yard trimmings has 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. To turn things around, the Ohio Environmental Protection Agency (OEPA) and the Ohio Department of Natural Resources' (ODNR) Division of Recycling & Litter Prevention have ...

  • Closed loop system takes manure and methane

    A CONVERSION plant in Mead, Nebraska is processing manure and methane to create ethanol and compost. According to Nebraska Governor Dave Heineman: “This plant sets a new standard for ethanol production in this state and our nation, and is an example of the innovation needed to take this industry to the next level. It lets America get its automotive fuel from the croplands of the Midwest instead ...

  • Composting

    Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...

  • 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 ...

  • 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 ...

    Latest Developments in Mid-to-Large-Scale Vermicomposting This overview of systems and operational projects describes factors which contribute to their success as well as the challenges that have forced sites to close. Many different approaches are being used to process large volumes of organic residuals with earthworms, ranging from relatively simple land and labor-intensive ...

  • The Role of Mangroves in Fisheries Enhancement

    In 2011 humans caught and consumed 78.9 million tonnes of fish, crustaceans, molluscs and other species groups from the world’s oceans, accounting for 16.6% of the world’s animal protein intake (FAO 2012). This is projected to increase further, to over 93 million tonnes by 2030 (World Bank 2013). Global demand for fish products has increased dramatically over recent decades. Fishing ...
