I just published a BSF composter design that uses a storage tote. The ramp system is easy to build and I tested it for a full season. The drainage system is experimental, but you could modify it if you want something with more testing behind it. LINKI'll say I don't know why BSFL aren't more popular! They are certainly easier (for me) than worms, crickets and mealworms. Free too, and so easy. Nutritious, safe and prolific, self propagating, harvesting etc. I had a DIY bin last year, and got some good production but didn't get the crawl off ramp 'down pat', this year I'm going to try again.
