BSF Larvae

My original thought was to have the black soldier fly larvae, the maggots, to eat away the beer brewing waste, the spent grain. But they are eating so much when growing up, finishing about 5 kg of wasted grains within 2 weeks. I had to go around town to collect rotten veggies and uneaten foods to feed them. The most surprising thing is that although they eat the hops, Chaff, but the beer hops are keeping everything from rotting which makes them unable to feed on the foor, they do like the rotting matter, fresh food is not so popular. Also, the hops were very wet after fishing them out of the mash brewing pot. That's the easy bit to deal with. I just mixed those with the grains which is not so bad. But the sediment of fermentation is hard to deal with (I think it is just a waste to throw them away). I had to cook the remaining dead yeast, protein and hop remain into the slush. The smell of hops lingered in my apartment for 2 days to a point I start to dislike the IPA beers or any hoppy beer, oops. But the slush is still too wet, because of its anti-bacterial nature, they are keeping the raw chicken head and other fruit matter fresh! It is too strong the sterilizer, I wonder how the frass, the left over from BSFL farm, is going to work with the plants. Without bacterial colonies in soils, it is hard to create a healthy soil. They are turning into pupa, they stop feeding. I have the next project to dry up the worm farm from the slush, the smell was not so good.
