August 1, 2017 - Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory-led research team has developed a simple method to convert used cooking oil into biofuel. The team’s approach combines modified, recovered carbon with sulfuric acids, which is then mixed with free fatty acids in household vegetable oil to produce usable biofuel. The study, done with collaborators Wake Forest University and Georgia Institute of Technology and detailed in Chemistry Select, provides a pathway for inexpensive, environmentally benign and high value-added waste tire-derived products—a step toward large-scale biofuel production, according to ORNL co-author Parans Paranthaman. In previous ORNL studies, carbon powders have proven useful in developing lithium-ion, sodium-ion and potassium-ion batteries and supercapacitors. The patent-pending, waste oil-to-biofuel conversion adds a new approach to waste tire recycling initiatives.
