  • Eco-friendly process combining physical–chemical and biological technics for the fermented dairy products waste pretreatment and reuse

    Residual fermented dairy products resulting from process defects or from expired shelf life products are considered as waste. Thus, dairies wastewater treatment plants (WWTP) suffer high input effluents polluting load. In this study, fermented residuals separation from the plant wastewater is proposed. In the aim to meet the municipal WWTP input limits, a pretreatment combining ...

  • Analysis of competitiveness of a dairy property through reverse logistics: a case study

    This paper aimed at evaluating the competitiveness of a dairy property located in the Western Paraná State that uses the reverse logistics of the animal waste produced by the activity. Therefore, we collected information related to the property and the activity by questionnaires and in loco observations seeking information regarding the drivers that affect the competitiveness of the property, ...

  • Dairy case study

    One of the world’s largest dairy product manufacturers realised that there was potentially a risk issue with one of the ingredients it used. The risk was purely hypothetical, there was no evidence of it ever having caused harm, but they knew that if the issue was raised by the regulator, they may have to cease production while a risk assessment was prepared. They therefore decided that they ...

  • 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 ...

  • EDTA in environments subjected to disposal of dairy effluent from processing plants

    The presence of Ethylenediaminetetraacetic acid (EDTA) in environments related to the disposal of dairy effluent has been investigated. An HPLC–UV analytical method was used to determine concentrations of EDTA in soil, surface and ground waters. Method detection limits were 1.5 mg/kg (dry weight) for soil, 1 μg/L for surface water and 2 μg/L for groundwater. A quasi one–dimensional vertical ...

  • Application of artificial neural network to model the energy output of dairy farms in Iran

    An artificial neural network (ANN) model was developed to assess the energy input–output prediction in dairy farms of Iran. Data used were culled from 50 randomly selected farms using face to face questionnaire approach. The energy input–output analysis was carried out for the parameters of ANN model. Based on performance measures, single hidden layers with 16 neurons in the hidden ...

  • Environmental input–output analysis of the New Zealand dairy industry

    This work presents data and analysis quantifying the total (direct and indirect) resource use and outputs (products and pollutants) of the New Zealand dairy industry for the year April 1997 to March 1998. It also identifies those sectors supplying the dairy industry which make significant indirect contributions to its total inputs and outputs. Although this data is 14 years old, it is the only ...

  • Data Highlight: Arab Grain Imports Rising Rapidly

    The Arab countries in the Middle East and North Africa make up only 5 percent of the world’s population, yet they take in more than 20 percent of the world’s grain exports. Imports to the region have jumped from 30 million tons of grain in 1990 to nearly 70 million tons in 2011. Now imported grain accounts for nearly 60 percent of regional grain consumption. With water scarce, arable ...

  • On the use of non-negative matrix factorisation to characterise wastewater from dairy processing plants

    A portable field spectrometer was used to record the time-resolved ultraviolet/visible (UV/Vis) spectrum of the effluent stream at two different dairy processing plants (a Drier Plant and Cheese Factory). The spectra exhibited significant variability. As an alternative to the partial least squares regression methods usually used in the online UV/Vis field a non-negative matrix factorisation ...

  • 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. ...

  • Treatment of farm dairy effluent with hybrid upflow multilayer bioreactor and activated sludge module

    Biological removal of nitrogen and carbon from farm dairy effluent (FDE) was studied with two laboratory-scale systems following nitrification and denitrification processes. Each system consisted of an upflow multilayer bioreactor (UMBR) as a pre-denitrification unit, an aeration tank (AT) as nitrification unit and a secondary clarifier. The optimization of two operational variables, total ...

  • Phosphorus forms in conventional and organic dairy manure identified by solution and solid state P-31 NMR spectroscopy

    Received for publication October 10, 2008. Organic dairy production has increased rapidly in recent years. Organic dairy cows (Bos taurus) generally eat different diets than their conventional counterparts. Although these differences could impact availability, utilization, and cycling of manure nutrients, little such information is available to aid organic dairy farmers in making nutrient and ...

  • Airborne endotoxin concentrations at a large open-lot dairy in Southern Idaho

    Received for publication December 5, 2008. Endotoxins are derived from gram-negative bacteria and are a potential respiratory health risk for animals and humans. To determine the potential for endotoxin transport from a large open-lot dairy, total airborne endotoxin concentrations were determined at an upwind location (background) and five downwind locations on three separate days. The downwind ...

  • Dairy manure compost quality effects on corn silage and soil properties

    Soil nutrients in dairy manure composts vary depending on the original manure or other additives, with consequent effects on crop production. An experiment addressing the effects of single applications of dairy compost of high quality (HQC) or low quality (LQC) at the incorporation rates of 0, 45, and 90 Mg ha-1 on corn (Zea mays L.) silage yields, forage quality, and soil nutrients was conducted ...

  • Linking Wisconsin dairy and grain farms via manure transfer for corn production

    One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...
