National Academies Releases Report on Sustainable Development of Algal Biofuels

On October 24, 2012, the National Academies released a report entitled Sustainable Development of Algal Biofuels, which was produced at the request of the U.S. Department of Energy (DOE). According to the report, biofuels made from algae could provide a domestic source of renewable fuel, but with current technologies, increasing production of algal biofuels to meet five percent of U.S. transportation fuel needs could “create unsustainable demands for energy, water, and nutrient...

Potassium Titanium Oxide SNUR Bans Manufacture of Particle Size Less Than 100 nm

On October 5, 2012, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) for potassium titanium oxide, which was previously the subject of a consent order under Section 5(e) of the Toxic Substances Control Act (TSCA). EPA states that, based on test data on the premanufacture notice (PMN) substance and structure activity relationship analysis of test data on analogous respirable, poorly soluble particulates (subcategory titanium dioxide), EPA...
