  • Algae PhotoBioreactor`s convert Carbon to Biofuels

    Engineering designers from fishace technologies in Perth, Western Australia have developed a modular APB (Algae Photo Bioreactor) that can be placed at mine sites and power plant facilities to capture up to 85% of greenhouse gas emissions, blamed for global warming. APB’s captured gases include contaminants such as carbon dioxide and nitrous oxides. CO2 produced from the combustion of carbon ...

  • States Develop New Strategies to Reduce Nutrient Levels in Mississippi River, Gulf of Mexico

    Summary The 12 states of the Hypoxia Task Force have devised new strategies to speed up reduction of nutrient levels in waterways in the Mississippi/Atchafalaya River Basin. High nutrients levels are a key contributor each summer to the large area of low oxygen in the Gulf of Mexico known as a dead zone. Each state has outlined specific actions it will take to reduce nitrogen and phosphorus ...

  • Nitrogen fertilizer works way into sea and destroys marine habitats - EC

    Substantial increases in the flow of nitrogen into the sea have raised concerns about marine pollution. New research shows that commercial fishing is playing an important, but now declining, role in transferring this nitrogen back onto land. Enormous amounts of nitrogen fertilizer are applied to agricultural land to increase crop productivity. However, the use of such fertilisers can be damaging ...

  • Small seaweed refineries could meet transport needs

    Mid-size towns in developing countries could produce transport fuel from small biorefineries that use land-farmed marine algae, proposes a paper presented today (15 November) at the International Mechanical Engineering Congress in Houston, United States. The authors illustrate their report with a design of an ...

  • Green machine: a new push for pond scum power

    Just the basic facts make you wonder why algae aren"t powering our civilisation already. The single-celled phytoplankton produce half our planet"s oxygen and are the fastest-growing green organisms known. In shallow seawater ponds on land, they can use sunlight and sewage to turn concentrated carbon dioxide - flue gas from coal burning, say - into usable hydrocarbons, half of which can almost be ...

  • Warmer Lake Tanganyika threatens East African fisheries

    The warming of Lake Tanganyika over the past century has made the lake less productive — posing a serious threat to fisheries, according to a study. The lake temperatures reached their highest levels in the past few decades, said the authors, something that can be attributed to anthropogenic climate change. Although it was known that the ...

  • Revolutionary technology improves lettuce harvest yields

    BiOWiSH™, a breakthrough enzyme technology, has boosted hydroponic lettuce weights by up to 30% at harvest time, according to results of a recent trial. The new technology was adopted during multiple full growing cycles at the Glenorie Hydroponics lettuce farm in New South Wales, Australia. The results showed BiOWiSH™ treated lettuce were 17% to 30% heavier at harvest time for red and ...

  • Water pollution exceeds drinking-standard limits in many OECD farming areas

    Pollution of rivers, lakes, and aquifers exceeds recommended limits for drinking water in farming areas in many OECD countries, according to a new OECD report. Environmental Performance of Agriculture in OECD Countries since 1990 shows that excess levels of nitrates, phosphorus or pesticides were found in more than one out of 10 monitoring sites in 13 OECD countries. Treating pesticide- and ...

  • EPA orders simplot cattle feeding company to change stock watering practice at grand view, ID, feedlot to protect the Snake River (ID)

    The U.S. Environmental Protection Agency has issued the Simplot Cattle Feeding Company a legal order to halt discharges from its nearly 700-acre feedlot complex near Grand View, Idaho. Simplot confines between 30,000 and 65,000 cattle year round at this feedlot facility near the Snake River in southeastern Idaho. EPA’s order directs Simplot to immediately cease all discharge of pollutants ...

  • Appeals Court sends `Dead Zone` Lawsuit Back to Judge

    A federal judge who ordered the Environmental Protection Agency to take action to regulate farm runoff and other pollution blamed for the Gulf of Mexico's annual oxygen-depleted "dead zone" must take a second crack at his ruling. An appeals court has ordered U.S. District Judge Jay Zainey to reassess his 2013 order telling the EPA to set federal limits on the nutrients nitrogen and phosphorous, ...

  • Science and sugar cane produce versatile harvest

    (IPS) - For nearly five hundred years, sugar cane was used almost exclusively for making sugar, with a handful of by-products like rum, alcohol and molasses. Now, in Brazil, it has become a source of multiple derivatives, and the focus of much scientific and technological research. Ethanol, or fuel alcohol, has become a major product, rivalling sugar, over the last three decades. But recently, ...
