Company unveils biodiesel plans
Plans to build a new biodiesel plant in Scotland have been unveiled. Ineos Enterprises said it was aiming to open the new facility at Grangemouth, where its parent company operates the oil refinery. Biodiesel, made from vegetable oil and diesel, is seen as a way of reducing greenhouse gas emissions.

Pacific Biodiesel opens Texas plant
Maui-based Pacific Biodiesel has started to produce biodiesel at its newest plant south of Dallas. The plant is officially called Pacific Biodiesel Texas and is co-owned with country music singer and part-time Maui resident Willie Nelson. It is Pacific Biodiesel's ninth operating biodiesel plant. The plant will make about 8,000 gallons per day of biodiesel, which runs inside any diesel engine. Although biodiesel can be made from several different "feed stocks," such as soybeans, peanuts or used cooking oil, most of the fuel at the Texas plant will be made from cottonseed oil grown at farms only 15 minutes from the actual plant.

Ethanol vs. Biodiesel
Amid a U.S. ethanol boom, new research offers another take on the long-debated question of whether corn grain ethanol provides more energy than its production consumes. A recent study that takes into account all the energy used in farming and processing corn to make ethanol concludes that there is a small energy gain, but that the gain from using soybeans to make diesel is far greater - and that biodiesel is less of a greenhouse-gas polluter, too.
