  • Unlocking the potential of poultry manure

    The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been ...

  • Rainfall-induced release of microbes from manure: model development, parameter estimation, and uncertainty evaluation on small plots

    A series of simulated rainfall-runoff experiments with applications of different manure types (cattle solid pats, poultry dry litter, swine slurry) was conducted across four seasons on a field containing 36 plots (0.75 × 2 m each), resulting in 144 rainfall-runoff events. Simulating time-varying release of Escherichia coli, enterococci, and fecal coliforms from manures applied at typical ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • Sorption, uptake and biotransformation of 17β‐estradiol, 17α‐ethinylestradiol, zeranol and trenbolone acetate by hybrid poplar

    Hormonally active compounds may move with agricultural runoff from fields with applied manure and biosolids into surface waters where they pose a threat to human and environmental health. Riparian zone plants could remove hormonally active compounds from agricultural runoff. Therefore, sorption to roots, uptake, translocation, and transformation of three estrogens (17β‐estradiol, ...

  • 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 ...

  • 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 ...

  • Process parameters analysis for the vermicomposting of shredded paper using Pheretimoid Spp.

    This study was to assess the effect of new species of earthworms, Pheretimoid Spp., on vermicomposting and compare the quality of vermicompost against compost produced from the same mix ratio of shredded office paper (SOP) together with grass clippings (GC) and cow manure (CM). Two composting experiments were setup in rotary drum composters namely: 1) composting of SOP, GC and CM followed by ...

  • Digested Dairy Manure To High-End Potting Soil

    Robert Joblin and Ted Sniegocki of Cenergy USA based in Little Rock, Arkansas, are not horticulturalists or agronomists. But they are anaerobic digester developers and when falling rates for renewable energy and the loss of the federal Investment Tax Credit grant hit at the same time, the financial models they had been using “fell down.” The need for additional revenue streams for AD ...

  • Removal of 2-methylisoborneol from aqueous solution by cattle manure compost (CMC) derived activated carbons

    The objective of this study is the synthesis of activated carbon derived from cattle manure compost (CMC) causing environmental problems using zinc chloride (ZnCl2) activation and to examine the suitability and performance of the prepared activated carbon (PAC) in removing 2-methylisoborneol (2-MIB) from aqueous solution. The influence of ZnCl2/CMC ratios and outgassing from the PACs on ...

  • Optimization of the thermophilic anaerobic co-digestion of pig manure, agriculture waste and inorganic additive through specific methanogenic activity

    The anaerobic co-digestion of three wastes (manure, rice straw and clay residue, an inorganic additive) at different concentration levels and their interactive effects on methanogenic activity were investigated in this work at thermophilic conditions in order to enhance hydrolytic activity and methane production. A central composite design and the response surface methodology were applied for ...

  • CAFO Manure Treatment-Struvite Removal and Struvite Prevention

    CAFOs (Confined Animal Feeding Operations) face struvite in their manure holding ponds and manure lagoons, as well as their recirculation systems. On a dairy farm in Neb. that operated with 15,000 milking cows, they were generating 500,000 gal per day of wastewater laden with manure.  Over the summer, they noticed a reduction in their pumping capacity because the first lagoon was ...

  • Little creek hog manure slurry store treatment case study

    The Challenge: Significant build-up of solids on the bottom of the slurry store (approximately five feet) with an expectation of another foot of accumulation by the end of the season (fall 2006).

  • Anaerobic co-digestion of cattle manure with rice straw: economic & energy feasibility

    Rice straw (RS) is one of the most abundant wastes generated in Valencia (Spain). Traditional waste disposal methods are harmful to the environment. The straw burning emits large amounts of toxic air pollutants and the straw burying produces uncontrolled anaerobic fermentation in the soil. The aim of this research was to evaluate the feasibility of cow manure anaerobic co-digestion with RS in a ...
