  • Removal and recovery of ammonia from chicken manure

    The feasibility of the conversion of organic nitrogen available in raw chicken manure (CM) into ammonia via hydrolysis and the removal of ammonia from anaerobically digested manure were evaluated in this study. Firstly, the hydrolysis experiments were performed and the effects of temperature, total solids (TS) content and retention time were investigated. The results showed that 90% of the ...

  • Prokaryote community dynamics in anaerobic co-digestion of swine manure, rice straw and industrial clay residuals

    The aim of this study was to analyze the effect of the addition of rice straw and clay residuals on the prokaryote methane-producing community structure in a semi-continuously stirred tank reactor fed with swine manure. Molecular techniques, including terminal restriction fragment length polymorphism and a comparative nucleotide sequence analyses of the prokaryotic 16S rRNA genes, were ...

  • A small plant with great success - case study

    The farm-based biogas plant operated by the Wienken family in Augustenfeld (near Löningen) is the first plant of its size built by bwe. Originally, the farm's operator had planned to install a straw heating element. However, since the input materials are available on the farm itself in their entirety, the decision to implement a biogas plant designed by bwe was obvious. One decisive aspect ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • New Mexico Business Weekly Passing biogas: R-Qubed project converts cow manure to methane

    Some locals sarcastically joke that the stretch of dairy farms along Interstate 10 south of Las Cruces should be re-named “Buenos Aires” (fresh air). It’s a reference to a less than aromatic sector of I-10 in southern New Mexico, not a reflection on the capital of Argentina. But that soon might change, thanks to a US$72 million plan by R-Qubed Energy Inc. of El Paso to build ...
