DIY Biodiesel video

DIY Biodiesel: Keeping It Safe, Keeping It Legal


The second installment of ATTRA's farm-scale biodiesel production webinar series. DIY Biodiesel: Keeping It Safe, Keeping It Legal helps the novice biodiesel producer on the right track to establishing safe and legal production practices. It covers safety practices including personal safety, workspace safety, materials handling and regulations, waste stream handling, methanol, compatibility with equipment and environmental safety and regulations.

Biofuels from Onions,

Onion Power: Potential Production of Biofuels from Onions and other Vegetables



Anaerobic digestion of fruit and vegetable waste can provide an energy source, reduce water pollution, and create a valuable soil amendment. Dr. Gary Hawkins, from the Department of Biological and Agricultural Engineering at the University of Georgia, presents new research findings on the anaerobic digestion of onions and other vegetables. This webinar is part of the Energy Training for Agriculture Professionals project, being offered by the National Center for Appropriate Technology and the Center for Environmental Farming Systems, with funding from the Southern Sustainable Agriculture Research and Education program.

Tecpar UFPR and develop new method to control fuel mixture

Tecpar UFPR and develop new method to control fuel mixtureA method to determine what percentage of biodiesel blend in diesel oil, developed by researchers at the Technology Institute of Paraná (Tecpar) and two professors from the Department of Physics, Federal University of Parana (UFPR), is in the process of recognition national and international patent and reference may be to control the fuel.
The main advantage of this method, which basically consists of the analysis of changes resulting from the emission of infrared radiation in the fuel, is that it is quite simple and can be used in portable equipment, facilitating the monitoring work at gas stations. From the moment the research is published abroad, later to patent applications in Brazil and the United States, the method has gained international visibility.
The patent process WO/2009/009843, published by the World Intellectual Property Organization (WIPO, its acronym in English) in early 2009, has not yet been completed. In Brazil there is a request to expedite the processing priority.
This technology, developed by researcher Bill Tecpar Jorge Costa and Marcelo Alisk by the employee, with teachers UFPR Wanderley Veiga and Cyro Ketzer Saul, has gained increasing importance in Brazil - especially since the approval of the Federal Law 11.097, which requires addition of 5% biodiesel in diesel fuel by 2013 pure. The physicist Marcelo Alisk was student of expertise in sensors of the Physics Department, UFPR, conducted with support from Tecpar between 2005 and 2006, during the development of research.
The work was presented to the chief executive of Tecpar, Julio C. Felix, in a meeting that was attended by researchers from two institutions that have developed the method, besides the technical director of the institute, William Zemke, and advisors. Felix expressed satisfaction in having more technology Tecpar as a reference. "It is a proven effective method that can simplify and unify the work of identifying the percentage of biodiesel blend in Brazil," he said.
Also discussed was the possibility of developing a portable device for measuring biodiesel blend using this method, and the project was presented to the Technology Incubator of Curitiba (Intec), which is linked to Tecpar.

Students Make Biodiesel, Padwa’s Mobile Creations

Students Make Biodiesel, Padwa’s Mobile Creations


This fall, James Pickett, an adjunct chemistry professor at Blackburn College, in Carlinville, Ill., will be putting his chemistry students to work producing biodiesel that the school can use to power small machinery, such as tractors and lawn mowers.
The idea grew out of Pickett’s contemporary chemistry course, which offers a unit on RENEWABLE FUELS. Rather than having his students do routine chemistry labs, Pickett thought it would be more interesting to have them produce biodiesel for the school. “The college has a sustainability program, and this seemed to be a natural fit,” Pickett says.
To make the biodiesel, the students will take used cooking oil from the school cafeteria as a starting material and combine it with an alcohol and a strong base. Pickett anticipates that each semester his class can produce up to 45 gal of fuel for Blackburn.
He acknowledges that the project will hardly put a dent in the school’s fuel budget. But what’s more important, he says, is that the students will see chemistry in the context of their everyday lives—and they will be helping their community.

Mobile man: Padwa's office doubles as an art exhibit.
Walk into the chemistry building at Emory University, and the first thing you’ll probably notice is a mobile. Not a mobile device, but one of those free-floating, asymmetrical objects dangling from the ceiling. Before you know it, you’re surrounded by mobiles, thanks to chemistry professor Albert Padwa, who has been collecting these WHIMSICAL CREATIONS since the 1970s.
Padwa usually picks up a mobile whenever he travels to a conference, and in recent years, he has supplemented his collection with mobiles he creates himself. Padwa draws inspiration from Alexander Calder, the famous American sculptor who is credited with inventing the dangling art pieces.
When the mobiles began filling his home, Padwa brought some of them to work. “I started giving away some of the mobiles I had created to my colleagues in the chemistry department,” he says. “Almost everyone has a mobile now.” Padwa notes that roughly 80 of his mobiles adorn the various offices and corners of the chemistry department; 40 of them are in his office alone.
He gives mobiles as gifts to celebrate special occasions. For example, he’ll give one to a professor who has just received tenure. During the holiday season, Padwa sends out greeting cards to friends and former students, and on each card is affixed a photo of a mobile. His enthusiasm for this art form has been infectious; some of his colleagues have created their own mobiles. Padwa says someone even gave him a mobile decorated with dangling amino acid structures that is now a dominant fixture in his office.
Although Padwa’s mobiles do not have an obvious chemistry connection, he claims that the ceiling hangers have been inspired by chemistry. “There is so much science that is inherently connected with the nature of complex molecules in three-dimensional space,” he says. “How I regard mobiles is that they float in 3-D. Mobiles possess oddball shapes, which are all in balance, and there is a lot of symbolism between 3-D mobiles and complex molecular structures. That’s why it ignites my imagination and enthusiasm, and that’s why I build them, much as I assemble complex natural products in our laboratory.”
Padwa hopes that his passion for collecting and creating mobiles will become part of his legacy at Emory: “They may not remember me for my science 25 years from now, but there will be enough mobiles in the chemistry building that everybody will remember me.”
