- A small bioreactor uses flies to break down waste.
- The system turns this waste into feed and fertilizer for farms.
- One person can build the device from common materials.
- It costs much less than large industrial waste plants.
- Larvae and frass are useful as feed and fertilizer.
- The bioreactor needs a cool, shaded space to work well.
- Users add water and wood chips and watch temperature.
