Tackling Restaurant Waste: Biodiesel and Biochar is a project in development by engineering students at the Cooper Union. Biodiesel and biochar are sustainable solutions for restaurants with large amounts of food waste. Over the course of a semester, our team designed a process by which a restaurant could convert all of their food waste into biodiesel and biochar, constructing a biodiesel reactor, a biochar stove, and a water filtration system in solidworks. Calculating energy usage and heating values, we’ve developed an interface that allows restaurants themselves to see how they fit into our solution.
