AB  - Abstract-Reviewed Presentation: At the onset of the year, Rum & Sargassum (R&S) partnered with the University of San Diego, through the Engineering Exchange (ExSJ) and Water Justice Exchange (WJE) to explore biomethane production using locally sourced waste in San Diego. The initiative drew inspiration from the successful R&S model used in Barbados to create a viable auto fuel equivalent. The formula, centered around alcohol-based wastewater, seaweed, and animal waste. A 2022/23 Industrial and Systems Engineering (ISyE) capstone team achieved promising results at the micro scale, using Kelp + Beer Wastewater + fish waste/manure from grass-fed ruminants. This formula, consisting of predominantly dry matter like the original R&S model, tripled bio-methane yields compared to biomass input. The micro-scale process, however, involved pretreatment with a food processor and blender to create a homogeneous substrate mixture before anaerobic digestion could be initiated. Energy used at the process start was not considered in the energy yield calculations.
Our  2023/24 ISyE Capstone Team will refine the formula further by comparing the results from the last team to more liquified versions requiring reduced energy input for substrate pre-treatment. The objective is to identify a formula with optimal net energy yields at the micro level and then transition to a larger scale for assessing usable energy output. Our presentation will focus on sharing our approach to achieving our objective utilizing ISyE methodologies, and discussing our experience engaged in an eco-social justice focused project in partnership with international collaborators.
