The purpose of our project is to analyze whether a waste byproduct can be monetized into a viable profit stream for Wonderbird Spirits. Spent grain, a waste byproduct created by the distillation process, is currently the company’s biggest source of material waste. The CME project team designed and built a trommel to aid liquid-solid separation of the spent grain so that the solid portion can be repurposed as feedstock for a vermicomposting setup. We also suggest vermicomposting setup for the distillery based on the needs and capabilities of Wonderbird Spirits. We present financial analyses detailing the cost of creating the trommel along with the possible revenue from the vermicast.
