New publication on pre-treatment of banana peels for BSFL composting

Alice Isibika and co-authors have published a new study in the journal Waste Management, on the application of pre-treatments prior BSFL treatment of banana peels as a fibrous and nutrient imbalanced substrate to enhance bioconversion ratio. The applied pre-treatments were non-protein nitrogen for balancing the carbon/nitrogen , heat and microbes(fungi and bacteria) pre-treatments for breaking down complex compounds into more readily available forms in the banana peels to be consumed by the BSFL. They found that direct addition of ammonia solution in the banana peel and addition of both  fungi (Trichoderma, Rhizopus) and bacteria (BSFL gut bacteria) improved the BSFL response efficiencies while heat treatment did not improve. For microbial pre-treatment 14 days was found to be the total time to achieve sufficient degradation of the banana peels for BSFL consumption.
