The blend is legally classified as a diesel fuel, which eliminates any operational or potential warranty concerns users may have.
Engineering students convert cooking oil previously used to prepare French fries, chicken and other favorites in campus restaurants to biodiesel.
An innovative UK company called bio-bean collects waste coffee grounds from coffee shops, office blocks, transport hubs and coffee factories, and recycles them into advanced biofuels.
Sixty brand new electric trolley buses will replace buses that have been in operation for over two decades. Concurrently, through unanimous Board of Supervisors approval, the SFMTA has purchased 61 new biodiesel-electric hybrid buses. The combined purchases are part of the agency’s five-year plan to replace the entire bus fleet.
APTA statistics for 2014 show that 16.9% of public transit buses were hybrid-electric. Coming in a close second, public transit systems report that 16.7% of U.S. transit buses used compressed natural gas (CNG), liquefied natural gas (LNG) and blends. Biodiesel is used by 7.4% of public transit buses. Other alternative fuels, such as propane and hydrogen, account for 0.3%.
The Bio-Bus can travel up to 186 miles on a full tank of gas, which takes the annual waste of around five people to produce.
Rising and fluctuating diesel and gasoline prices cause stress and uncertainty for fleet operation bottom lines. Fortunately, transit fleet operators may choose from several alternative fuel and vehicle technologies that can provide price stability, lower fuel costs and reduced emissions.
Transit agencies across the country are looking for ways to cut emissions, reduce petroleum use and save on fuel costs. Sun Tran, operated by the City of Tucson, Ariz., has been successful on all three fronts and serves as a great example for other public transit providers.
To expedite the purchasing process, the agency joined a current, competitively bid vehicle contract with the State of Minnesota.
The service began in 2005 with five buses running one route and has grown to three routes, serving more than two million rides per year to students. The service has now expanded to 12 buses, running two routes Monday through Friday.
