That's excellent. Thanks for the info. Pretty impressive that you can regain protein content from vegetable matter like that. I wonder if it's all sustainable over a long time period or if it requires some kind of supplements to sustain the system.
there will always be a nutrient issue, as with any field you pull matter out of, but the volume is minimal compared to fertilizing an entire field. you can make protein chains but not minerals.
Another thing to keep in mind is that if you have any type of closed loop, you'll be adding nutrients by default. For example, if you have the food waste -> BSFL -> fish -> plants -> harvest loop, you'll be adding food waste from outside the loop, which will have the nutrients you need. If you continue consuming bananas, banana peels will be an excellent source of magnesium and potassium that will make its way into the plants through the loop mentioned above.
