  • 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 ...

  • 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 ...

  • 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 ...

  • Statistical modelling of the impact of some polyphenols on the efficiency of anaerobic digestion and the co-digestion of the wine distillery wastewater with dairy cattle manure and cheese whey

    The objective of this study was to determine the effectiveness of anaerobic digestion in the treatment of polyphenols (PP) present in olive mill wastewater (OMW) and wine distillery wastewater (WDW). Anaerobic Toxicity Assay (ATA) was conducted to assess the impact of the most representative phenolic compounds present in OMW and WDW: catechol, tannins and p-Coumaric acid, on biogas production. ...

  • Spatial distribution of some microbial trophic groups in a plug-flow-type anaerobic bioreactor treating swine manure

    Anaerobic digestion of swine manure is carried out by a consortium of microbial species, including volatile fatty acid (VFA) producers, VFA-degraders and methanogens. The distribution of five phylogenetic groups within a plug-flow-type anaerobic bioreactor consisting of eight serially-connected tanks was examined through the sequential digestion of swine manure. Quantification was carried out ...

  • The CAMBI process and agriculture, a sustainable solution?

    Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...

  • Adding Value To On-Farm Digesters

    ANAEROBIC digestion of dairy manure and food processing residuals in Michigan is not a new undertaking. Over the years, 11 farm digesters were constructed in the state, of which four are still operational, reports Michelle Crook of the Michigan Department of Agriculture in a presentation in the spring of 2007. “Three of the operating digesters are for livestock manure and one is for food ...
