Fruit to fuel

first_imgBy April SorrowUniversity of GeorgiaHalf of all the fruit grown in Georgia is never eaten by people or animals. It rots in the fields. A University of Georgia researcher says that spoiled fruit could fuel cars. That wasted fruit can be converted into bioethanol through a fermentation process, said Elliot Altman, program coordinator for the UGA Center for Molecular Bioengineering.“All fruits are 10 percent sugar, or potentially 5 percent ethanol,” said Altman, an engineer with the UGA College of Agricultural and Environmental Sciences. “It’s a real opportunity.”The fermentation process could create a high-protein byproduct, which can be used in animal feed, called dried distillers grain.The largest opportunity in Georgia lies in watermelons and peaches. Last year, the state harvested one billion pounds of watermelon and more than 61 million pounds of peaches. The same amount rotted in the fields. The fruit is left behind because it doesn’t make the grade for commercial sale. Consumers don’t want fruit that doesn’t look perfect, even though it is fine to eat in most cases. Some of the discarded fruit is used in preserves and juice, but 50 percent never leaves the field.Ethanol conversion is not possible on a small scale like biodiesel operations. Getting enough commodity groups excited about converting the waste to fuel is one battle Altman hopes legislation may help with. “One farmer isn’t big enough to set up operation,” he said. “If packers knew in advance the fruit would be used for something, they could gather it in a separate place for transport to the ethanol plant.” Government regulations mandate the blending of 5 percent ethanol into gasoline by 2009 and 10 percent by 2011. The Renewable Fuel Standard program will increase the volume of renewable fuel required to be blended into gasoline from 9 billion gallons in 2008 to 36 billion gallons by 2022. But, ethanol plants aren’t cheap. “You can’t build a small plant,” he said. “To be cost effective, most experts agree that a plant would need to produce at least 10 million gallons of ethanol a year.”Altman and his colleague Mark Eiteman, a biological and agricultural engineering professor, are working on techniques to simplify the commercial ethanol plant, making it cheaper to produce ethanol and DDG.For example, their group has researched adding expired table sugars to increase the ethanol yields that can be obtained. Access to waste fruit is not a year-round venture, he said.“Even with a couple of fruits, a fruit-ethanol plant would only be operational for half a year, and the infrastructure for an ethanol plant is a significant investment,” Altman said.Altman is currently researching several other products – like grain sorghum – that could be used when the fruit is not available. “It has silo storage capability and is able to grow in areas of Georgia not suitable for anything else,” he said. “It does not take away from other crops and would not hurt the food market.”Georgia also has potential to produce ethanol from bakery waste. “We have a unique niche in the Atlanta area with our bakeries.”(April Sorrow is a news editor with the University of Georgia College of Agricultural and Environmental Sciences.)last_img read more

Syracuse’s next opponent: What to know about Pittsburgh

first_img Published on January 18, 2019 at 3:21 pm Contact Billy: [email protected] | @Wheyen3 Pittsburgh (12-5, 2-2 Atlantic Coast) and Syracuse (12-5, 3-1) were long-time Big East rivals that have renewed their battle in the ACC in recent years. Both come off major upsets on Monday night: SU at No. 1 Duke and Pitt against No. 11 Florida State. They’ll meet at 2 p.m. on Saturday in the Carrier Dome looking to start winning streaks.Here’s what to know about the Panthers.All-time series: Syracuse leads, 68-45Last time they played: Last season, Syracuse played Pittsburgh twice and won both times. The second meeting came on the Panthers’ home court, and the Orange pulled out a 60-55 victory. That win featured Bourama Sidibe’s best game of his freshman season: an 18 point, 16 rebound performance that led SU in both categories. Tyus Battle joined the center in double-figure scoring with 14 points of his own. Both Sidibe and Paschal Chukwu blocked three shots.The Pittsburgh report: Like each of Syracuse’s last two opponents, Pittsburgh enters its meeting with the Orange ranking No. 29 in the country in defense, per KenPom.com. The Panthers limit both 3-point and 2-point shooting to rates well below the national average. After SU’s win against Duke, head coach Jim Boeheim said that he expects the Panthers to play a lot of zone, a defense the Orange struggled to handle in their loss to Georgia Tech.AdvertisementThis is placeholder textThe Panthers feature four players who score in double figures: Xavier Johnson, Trey McGowens, Jared Wilson-Frame and Au’Diese Toney. Those four leaders are also the four Pitt players to have made double-digit 3s this season. Johnson holds the keys to the Panthers’ offense, as in addition to his team-leading scoring total, he leads the way with 4.7 assists per gameOn the defensive end, it’s McGowens averaging 2.7 steals per game as Pitt’s playmaker. Six-foot-10 sophomore Terrell Brown averages 2.5 blocks per game as the Panthers’ top rim protector.McGowens starred in Pittsburgh’s Monday win over Florida State, scoring 30 points and stealing the ball five times. He worked his way to the line consistently, eventually shooting 19 free throws in the win. Johnson shot 10 free throws of his own for the Panthers on Monday, and Pitt gets the fifth-highest percentage of its points from the foul line of any team in Division I, per KenPom.com.How Syracuse beats Pittsburgh: Rely on rim protectors and avoid fouling. Only three teams have been blocked on a higher percentage of their shots this season than the Panthers, who have been rejected 14.1 percent of the time they shoot field goals. For perspective: That’s higher than the individual block rate of Paschal Chukwu, who ranks ninth in the country. Coming off a 10-point, 18-rebound showing at Duke, Chukwu could be key in using his length to disrupt Panthers’ shooters that are susceptible to being denied near the basket.As mentioned above, Pittsburgh relies on its foul shots more than almost any team in the country. More than a quarter of the Panthers points come from the charity stripe, and they shoot it at 72.5 percent from there, above the national average. Boeheim has said before that the Orange play a zone in part to limit fouls, and against a Pittsburgh team that likes drawing fouls, that will become all the more important.Stat to know: 220That’s the number of free throws Xavier Johnson and Trey McGowens have combined to shoot this season.KenPom.com odds: Syracuse is given a 77 percent chance to win, by a projected 70-62 scorePlayer to know: Xavier Johnson, guard, No. 1Johnson is already a freshman and already the best player the Panthers have (along with the best Fortnite and NBA 2K player on the team, per his roster bio). He leads them in scoring and assists, along with being second in 3-point attempts and free-throw attempts. The 6-foot-3 Johnson will face a test when presented for the first time in his career with Syracuse’s 2-3 zone. How he responds could be crucial to the outcome on Saturday.
