Black soldier fly larvae (BSFL) composting can be used to recover more waste for composting due to their ability to compost meat and oil. A continuous system for black soldier fly larvae composting would enable facilities to efficiently compost more waste with a smaller footprint, thus eliminating waste sent to landfills and hauling compost to a bio-digester facility. This continuous system would be easy to clean, allow larvae to migrate for harvesting, and allow flies to lay eggs. This system would also be suitable in climates that are not naturally suited for BSFL. Current systems are a batch process which needs frequent cleaning, has a design that is too deep for larvae to operate, and is not good for small batches.

The goals of this project are to develop a functioning continuous system for rearing BSFL in an indoor shed with a one square meter footprint. In order for the system to be continuous, the larvae must thriving, and pupae must be removed three times a week. The system must be able to process 12kg of Gracie's food waste per day. The expected end requirement is a working prototype, a technical paper, test results, an operator’s manual, and assistance for the EPA P3 Expo in April 2017.

Below is a continuous system flow chart designed by our team to better depict the processes that will be worked on for the senior design project.
