Onion and garlic waste from the food industry could be used to mop up hazardous heavy metals, including arsenic, cadmium, iron, lead, mercury and tin in contaminated materials, according to a research paper published in the International Journal of Environment and Pollution.
One year after the MIR submersibles dove into the depths of Lake Geneva, the elemo program is delivering its first scientific results. And with the support of Ferring Pharmaceuticals, the operation will be extended with a campaign to make observations above the lake surface from a sensor-packed ultralight aircraft. The same experiments are planned above Lake Baikal in Russia.
Researchers at Aalto University have developed a simple method for reducing the amount of phosphorus in the wastewater of a pulp mill. The method is called simultaneous precipitation using iron sulphate. A separate treatment stage is not required, as the precipitation takes place simultaneously with the actual biological wastewater treatment.
Ethanol, a component of biofuel made from plants such as corn, is blended with gas in many parts of the country, but has significantly different fluid properties than pure gasoline.
Pollution from fossil fuel burning and forest fires reaches all the way to the Arctic, even though it should decay long before it travels that far. Now, lab research can explain how pollution makes its lofty journey: rather than ride on the surface of airborne particles, pollutants snuggle inside, protected from the elements on the way. The results will help scientists improve atmospheric air-quality and pollution transport models.
Nitrogen is a beneficial plant fertilizer in small amounts, but large amounts cause negative impacts on ecosystems, such as water pollution, acidification of soils, increased productivity of invasive species, increased probability of wildfire, and a decline of native plant diversity.
Seattle is known for progressive thinking when it comes to adopting environmentally friendly practices and cutting-edge clean technology, and its vehicle fleets are no different. Fleets in the Puget Sound area such as Sea-Tac’s MasterPark, the City of Edmonds and Seattle Children’s Hospital are part of a nationwide movement to use American-made propane autogas, which is both cleaner than gasoline and more affordable to implement than other alternative fuels.
Curtin University research showing that bacteria were responsible for the excellent preservation of a crab-like fossil during the Devonian period suggests that organic geochemistry could be a useful new tool for understanding ancient environments.
RJ Lee Group, Inc.'s mobile laboratory is now available to aid in assessing and monitoring organic contaminants that may occur in the aftermath of Hurricane Sandy.
Thermal Energy International Inc. (TSXV: TMG), a leading provider of custom energy and emission reduction technologies for energy intensive industries and institutions worldwide, today announced that it has received a purchase order totaling approximately $330,000 (£207,163) from a publicly funded hospital for the installation of its GEM® steam trap technology.
