Great review article by colleagues and friends (Stefan Dinner and Christian Zurbrügg) assessing the global warming potential when using the BSF to recycle biowaste.
Mertenat, A., S. Diener, and C. Zurbrügg. 2019. Black soldier fly biowaste treatment – assessment of global warming potential. Waste Management 84: 173-181.
The main take-home message:
1. CO2 emissions from BSF recycling waste is 47X lower than from composting alone.
2. Global warming potential by BSF is primarily attributed to residue post-composting and the electricity needed to run the system.
3. While there is potential, and no one is denying it, the BSF has more benefits than simply allowing the waste to compost. Using the BSF to recycle waste and then replacing fishmeal with BSF can reduce global warming potential from this industry sector by 30%.
What can I say? Money in the bank (translation- good news!).
