My team has mechanized a composting approach called bokashi, which inoculates organic matter in an anaerobic environment using a mix of bacteria referred to as "EM" (essential microorganisms) containing Saccharomyces spp., Lactobacillus spp., and Rhodopseudomonas spp. The result is fermented organic waste that can be used like compost, basically probiotics for the soil. It's popular for home use because it doesn't smell and works pretty fast, but it's typically applied in a low tech process using plastic buckets.
Our project has been to automate it and make it even faster, with intentions to scale into a municipal facility. We bought some wireless sensors for quality control purposes to help determine when it's "done", and now what we really want to find out is what the microbial population of the end product looks like after fermentation is complete. We want to be able to substantiate claims about its composition and benefits, but also prove that it's safe (mostly by ruling out pathogens). Ideally we'd also like to compare this to the same material before treatment.
For anyone interested, there's also a possibility to join the team long term. Someone who is knowledgeable about soil science would be a huge plus.
Thanks,
Amanda
