  • 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 ...

  • Animal Manure or Sludge Organic Fertilizer Production

    Introduction of Animal Manure or Sludge Organic Fertilizer Production Line Organic fertilizer production line is designed for producing organic fertilizer from animal manure or sludge, without any chemical ingredients. As chickens, pigs have a poor digestion, can only consume 25% of the nutrients, so other 75% of feed nutrients with feces discharge can be produced to the dry ...

  • Stimulation of the hydrolytic stage for biogas production from cattle manure in an electrochemical bioreactor

    Electrical current in the hydrolytic phase of the biogas process might affect biogas yield. In this study, four 1,150 mL single membrane-less chamber electrochemical bioreactors, containing two parallel titanium plates were connected to the electrical source with voltages of 0, −0.5, −1 and −1.5 V, respectively. Reactor 1 with 0 V was considered as a control reactor. The trend of biogas ...

  • Case study - Guangdong Academy of Agricultural Sciences (GDAAS)

    There are 13 research institutes under the GDAAS, including specific foods and crops and fertilizer research. The main mission of the institution is to carry out non-profit research around agricultural science and techniques.  As one of the most important agricultural crops institutions, the Crops Research Institute has been focusing on the development of new varieties of crops, cultivation ...

  • A `classic` for agriculture - case study

    A 500 kW-Biogas plant (typical to its kind in every regard) is located in Gehlenberg. There, 500 kW were legally defined as the permissible maximum limit value for agricultural operations. In Gehlenberg, the competent consulting services provided by bwe attracted particularly positive attention. After all, the plant (operational since 2006) is impressive in its high degree of overall efficacy and ...

  • 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 ...

  • 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 ...

  • 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 ...

  • High performance biogas plants for organics waste diversion

    Wild fluctuations in prices for agricultural products and mushrooming prices for energy can greatly influence the economics of biogas plants. Long term reliable profitability calculations are becoming increasingly difficult. Generally speaking, however, rising energy prices have a positive effect on the economics of well designed biogas projects. By selecting low cost feedstock, the profitability ...
