BSF tote composter
Storage tote composter

This is a new black soldier fly composter design that combines both proven and unproven concepts. My hope is that the construction techniques might give you some ideas, and that the vertical drain system will be effective for more than just filtering the liquids. I chose a transparent tote because I have a theory that ultraviolet rays from indirect natural light might help control bacteria, as it does in a natural setting.

The most obvious advantage to a vertical drain is that you can access it from the top without removing the waste/castings. If a filter medium is used it could be removed for cleaning, and the perforated surface of the drain can easily be flushed with water to help address clogging. As an added potential benefit it may improve oxygenation at the lower levels of the waste, encouraging more feeding there.
