  • Pork Slaughterhouse - Case Study

    Introduction Prior to the installation of two 1,200 gpm GEM (Gas Energy Mixing) Systems, CWT’s Client discharged approximately 1.9 million gallons per day (mgd) to their onsite pretreatment plant consisting of an Infilco Dissolved Air Flotation (DAF) unit service with a Nikuni pump, and a Maxair Clarifier (DAF) for further removal of contaminants. Float from both units was heated and ...

  • Case study - Converting livestock waste lagoons into a prosperous ROI

    A Missouri project, believed to be the largest and most comprehensive livestock manure-to-energy of its type in the world, is currently under way. The project efficiently treats waste from approximately 2 million hogs. The farms are being covered by Industrial & Environmental Concepts, a designer and installer of cover systems for wastewater lagoons and tanks. Roeslein Alternative Energy of ...

  • Simultaneous removal of rotavirus and adenovirus from artificial ground water using hydrochar derived from swine feces

    Hydrothermal carbonization technology can convert fecal waste into a valuable carbonaceous product referred to as hydrochar. We investigated the potential of fecal waste-derived hydrochar as an adsorbent for virus removal in water treatment. Swine feces was hydrothermally treated under two conditions: at 180 °C for 2 h and 230 °C for 7 h. The resulting solid products (hydrochar) were evaluated ...

  • CRISPR is coming to agriculture — with big implications for food, farmers, consumers and nature

    Gene editing offers dramatic advances in speed, scope and scale of genetic improvement. It also offers an opportunity for more nuanced GMO governance. Very few technologies truly merit the epithet “game changer” — but a new genetic engineering tool known as CRISPR-Cas9 is one of them. Since we first developed the ability to alter the genetic material inside a plant or animal in ...

  • Removal of humic acid from composted hog waste by the white-rot fungus, Phanerochaete chrysosporium

    The potential hazards of humic acid (HA) associated with hog waste effluent, coupled with increasing awareness of environmental problems, have prompted many countries to control disposal of effluents into water bodies and to maximize removal of HA. Here we employed the white-rot fungus, Phanerochaete chrysosporium, to degrade the HA in composted hog waste effluent, evaluated by the response ...

  • Pretreatment of piggery wastewater by a stable constructed microbial consortium for improving the methane production

    A stable aerobic microbial consortium, established by successive subcultivation, was employed to solubilize the solid organic fraction in swine wastewater. In the 30 days' successive biological pretreatments, 30–38% of volatile solids and 19–28% total solids in raw slurry were solubilized after 10 hours at 37 °C. Meanwhile, soluble chemical oxygen demand ...

  • Soy entering valuable wetlands of the Paraná Delta, Argentina

    Due to the enormous emphasis on soybean cultivation within Argentina, activities such as cattle raising but also the cultivation of soybeans are increasingly pushed to more marginal and vulnerable areas, where the cost of land is lower. The Paraná Delta, one of the most unique and important wetlands regions in the world, is one of these places. Although the region is not ...

  • Producer of pet and livestock vitamins and minerals relies on rotary batch mixers

    ADM Alliance Nutrition, Inc. is a leading manufacturer and distributor of vitamin and trace mineral pre-mixes, ingredients and food additives used in manufacturing pet food products. In addition, about 10 per cent of the company's output is mixes for bovine and swine feed. "We run about 1100 pre-mixes from 400 different powdered ingredients largely for pet food producers," notes Alliance ...

  • Have Your Steak and Eat It, Too

    In our recent feature, “Has Meat Met Its Match?,” writer Rowan Jacobsen explores ways people can (now and possibly in the future) reduce the environmental and food security impacts of their diets, including entomophagy (bug-eating), synthetic meat and vegetarian substitutes. If none of those fits your needs, there are plenty of other ways ...

  • Peru Agribusiness Report Q1 2014

    Our outlook for Peru's agricultural sector remains positive. The livestock sector is very dynamic, and investment into the country's ethanol sector is boosting sugar production. Export crops, such as coffee and cocoa, are hampered by a lack of infrastructure and investment, but there is scope for strong growth in both, particularly as Peru is becoming increasingly recognised for organic and ...


  • Taenia eggs in a stabilization pond system with poor hydraulics: concern for human cysticercosis?

    The objective of this study is to compare the removal of Taenia eggs to the removal of Ascaris eggs in a wastewater stabilization pond system consisting of three ponds in series, where the hydraulic residence time distribution has been characterized via a tracer study supported by computational fluid dynamics modeling. Despite a theoretical hydraulic retention time of 30 ...

  • Characterization of polyhydroxyalkanoate-producing bacteria isolated from sludge of commercial pig farms for producing methyl esters

    The objectives of this work were to isolate and characterize the polyhydroxyalkanoate (PHA) producing bacteria in enriched piggery sludge and make methyl esters from PHA for industrial applications. The strain ECAe24 isolated from piggery sludge with the highest PHA production was selected to produce PHA and then methyl ester by trans-esterification using glucose as substrate under mesophilic ...

  • 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). The Objective of the treatment: Preventing the further accumulation of solids and reducing the existing level of sludge in the slurry store using the BactiDomus® Technology Bio4Swine® In 2006 the ...

  • Occurrence of tylosin in swine wastewater in Mexico

    This study determined a tylosin concentration in swine wastewater located in a Mexican pig farm, during different stages of the pigs' growth. The detection of antibiotics in swine wastewater is complex due to its high concentration of solids. Analytical method was developed for detection of tylosin in swine wastewater and swine slurry. Average recoveries of tylosin in the liquid and solid ...

  • Carbon footprint of breton pâté production: A case study

    This study targeted nine different pork pâtés, produced with pork from different meat production systems (conventional, organic and other quality certifications). Besides Greenhouse Gas (GHG) emissions, the study also included a detailed analysis of product nutrition. Results show that the GHG emissions range from 200 g CO2e per 100g of product conventional pork pâtés and 330 g CO2e per 100g ...

  • Overfishing Threatens Critical Link in the Food Chain

    The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten ...
