Food vs. Fuel in 2013
Food vs. Fuel in 2013 By MATTHEW L.

In coming days, the Environmental Protection Agency’s to-do list will include setting a standard for the amount of advanced biofuels that refiners will be required to blend into gasoline and diesel supplies in 2013. The question is tricky because production in one category, cellulosic fuel from nonfood sources like corn cobs, stalks, wood chips and garbage, has not met the target set by Congress. The E.P.A. has the authority to adjust the quotas as needed, but the issue is complicated. The quotas were laid out in 2007 when Congress established a renewable fuel standard. Under its targets, production of cellulosic fuel was supposed to hit one billion gallons next year, up from 500 million in 2012, 250 million in 2011 and 100 million in 2010. But so far output is near zero because no one seems to have hit on a commercially successful recipe. So far the E.P.A. has had little choice but to repeatedly waive nearly all of the cellulosic requirement, but this has led to bitter complaints from the refiners, who say they are still required to use small quantities of a fuel that does not exist or face fines. Even as the agency waived most of the cellulosic requirement, it kept intact a larger 2.75 billion-gallon quota for “advanced” biofuels in general, which includes cellulosic, ethanol made from Brazilian sugar cane and biodiesel made mostly from soybeans. Production of biodiesel or sugar-cane ethanol is favored because each process emits relatively little carbon dioxide, the predominant greenhouse gas, meaning it has an advantage on the global warming front. Keeping the quota for advanced fuels intact was more or less O.K. when the agency waived smaller cellulosic mandates, said Jeremy I. Martin, a senior scientist in the Union of Concerned Scientists’ clean vehicles program. But it’s going to be a problem if the agency waives a one billion gallon requirement for 2013, he warned. If the overall 2.75 billion quota for advanced fuels is not reduced, the biodiesel and the sugar-cane ethanol will have to make up the difference. And if that happens, Mr. Martin argues, the quota will start putting more pressure on food supplies. Various other industrial users of food, especially companies that raise chickens, turkeys, hogs and beef, have meanwhile been trying to get the mandate for corn ethanol reduced, but the E.P.A. has declined to do so. The biofuel industry has been pushing hard to maintain the quotas, with waivers for cellulosic fuels as needed, year by year. A new industry report catalogs a growing number of efforts to produce cellulosic biofuels, albeit commercially unsuccessful ones. “All in all, the post-election environment in Washington seems to promise continuation of stable policy support for advanced biofuels commercialization and the robust growth of the industry,” Brent Erickson, executive vice president of the Biotechnology industry Organization said in a letter to supporters this month. Mr. Martin’s theory is that E.P.A. should stay the course. “We’re going to have to accept that the cellulosic fuels are late,’’ he said, but it would be better to delay the quotas than to eliminate them. “Going in the right direction a little more slowly is better than going in the wrong direction,’’ he said.

Forestry Commission Releases Biomass Harvesting Guidelines
Published: 5/7/2013 12:35:02 PM Columbia, SC — Foresters with the South Carolina Forestry Commission have developed guidelines which address the emerging practice of harvesting woody biomass for energy. Biomass generates energy. Forest products manufacturers have known this for generations and have produced their own electricity on-site using bark, sawdust, and other waste wood. “Woody biomass is a renewable resource that has the potential to supply 12-13% of the electricity used in South Carolina,” said Dr. Tim Adams, the Commission’s Resource Development director. The new biomass harvesting BMPs are aimed at protecting water quality, plant and animal diversity, soil nutrition/quality, and site productivity in and around harvesting operations. These are places where logging residue and other woody materials accumulate. The recommendations build upon our existing and successful Best Management Practices (BMPs) used by landowners and timber harvesters to minimize environmental impacts and stay within compliance of regulations. As was recently announced, SCFC sees a 93% compliance rate with its guidelines for harvesting timber. Logging, road building, site preparation, and even tree planting are intensive operations and reputable operators in SC can be trusted to work in such a way as to protect the land and water. On the national scale, South Carolina is a success story in this area. Wood demand is expected to increase dramatically in coming decades. The global population and even wood use per person both are on the rise as emerging markets and improving standards of living worldwide become the norm. As the “wood basket” of the world, the southeastern US is well positioned to play a major role. We have more standing wood today than we did 100 years ago. The vast majority of SC’s timberland is privately owned and the changes ahead bode well for our state, its people, its economy and its environment. Sustainable forestry is our insurance policy for the future. As woody biomass utilization gains momentum (initially for European markets as an energy source), we prepare by adapting Best Management Practices to biomass harvesting. As this new market develops, the SC Forestry Commission is committed to helping harvesters and landowners prepare for the future. More information and the guidelines themselves are available online.
