You are capturing a waste stream, that’s better than nothing as long as you handle it all appropriately. I tried something similar once, threw all food wastes including meat and everything else into a food safe HDPE container, then I filled the remaining container with water and some soil to putrify. I let it sit for two years. I was trying to model an anaerobic digester or the bottom of a pond. Then I dug a deep whole in my garden in the fall, poured the whole thing into it and covered it with soil. In the spring melons planted on top. It scared me to handle it a little because who knows what’s growing in it. But I wouldn’t completely rule out the technique in the future. Would have been nice to have been able to get samples checked and understand what might be growing. But biology and time should fix anything.
