Output\Input Assumptions• “First” year: 40 brew cycles of 9 days• Spent grain allocated roughly ½ & ½ to

mushrooms and biodigester• Allocate roughly equal space for oyster and

shiitake mushrooms; get similar revenues• Worms double in numbers and process 300

times their mass in waste in a 90 day cycle.• Algae consume all solid biomass from

biodigester• Fish convert all the algae biomass into food.

Outstanding Questions

• Spent grain. What determines the division between mycoculture and biodigester?

• Mycoculture. What determines the species mix: space, potential market, or both?

• Biodigester. What is the optimum mix of solids and wastewater?

• Vermiculture. What is the value of worms as enzyme producers?

• Aquaculture. How do the biomass and water flow requirements depend on pond size?
