If its to be truly sustainable then a better food source needs to be found
here in Indonesia that seems to be rice bran and the waste from making Tofu and tempe. the skins of the soybean
however id like to know what other non food items you can use to grow them
i see youre using oats in the photo which is a perfectly good animal and human food in its own right
ideally we would find something that isnt food, and turn it into food
That's a great reply, I will do some reading and thinking about that. Very good point about being truly sustainable. Thank you for the comment! I will be working on your question.
In Asia we use rice bran mixed with soy bean skins generated from making tofu and tempe. i am also seeking non soy additions to avoid the pesticides and the GMO soy issue. there are other legumes and high protein leaf meals that we may be able to grow onsite and use to boost the protein content of the rice bran.
