  • 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 ...

  • Legacy tracking methods can sometimes result in false positives

    Over the past decade, there have been several major pipeline failures that have had significant environmental impact. The high consequence of a rupture failure makes these pipelines some of the most regulated assets in the world. To reduce risk on these pipelines, operators use inline inspection (ILI) pigs for multiple functions, such as cleaning or assessing the condition of a pipeline, or to ...

  • How ILI Pig Tracking can be dangerous if done incorrectly

    Pipeline pigs are tools that are inserted into a pipeline and pushed along the pipeline by the product flowing through the pipeline. There are many different types of ILI tools. Some are used to clean the pipeline, while others are used to inspect the pipeline for deformities or corrosion damage. Some are even used to purge different products in a multi-product pipeline. Inline inspection (ILI) ...

  • 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 ...

  • Cultivation of an Arthrospira platensis with digested piggery wastewater

    An Arthrospira platensis strain ZJWST-S1 was isolated in Jiaxing City, China, which proved able to proliferate quickly in undiluted digested piggery wastewater (DPW), and the protein content in the algal biomass was high. Single factor experiments showed that the strain was able to quickly grow in a Zarrouk medium as the dosage of sodium bicarbonate, nitrate-nitrogen and phosphate-phosphorus ...

  • 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 ...

  • 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 ...

  • 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 ...

  • How to Pick the Right Ice Melter For Your Needs

    We get a lot of calls asking about what deicer to use.  What are the best products to melt the ice and snow on city streets, parking garages, hospital entry-ways, sidewalks, and driveways?  What about the daycare center where children crawl and they pick up deicers on their hands and then potentially taste them?   How about the ...

  • Design of an integrated piggery system with recycled water, biomass production and water purification by vermiculture, macrophyte ponds and constructed wetlands

    Since 2001 the swine experimental station of Guernévez has studied biological treatment plants for nutrient recovery and water recycling, suited to the fresh liquid manure coming out of flushing systems. An integrated system with continuous recycling was set up in 2007, associated with a piggery of 30 pregnant sows. It includes a screen, a vermifilter, and macrophyte ponds alternating with ...
