Food Waste Management Utilizing Black Soldier Fly Larvae

Abstract

Food waste is a growing concern in developing countries. This study aims to implement food waste bioconversion by utilizing black solider fly larvae for two eateries' food waste. The bioconversion process used 0.5 g of black solider fly eggs for 14 days in the six bio ponds. After 14 days, the waste, larvae, and compost are separated using sieves to measure the larvae and compost production. The bioconversion process is evaluated based on bioconversion characteristics and black soldier fly larvae and compost produced. Waste Reduction Index, Fresh Matter Consumption Rate, Dry Matter Consumption Rate, Dry Matter Rate, and Efficiency of Conversion of Digested Feed evaluated the bioconversion characteristics for reduction. According to the experimental results, utilizing BSFL is adequate for food waste management, effectively reducing up to 62.6%. Simultaneously, the fresh larvae and compost are produced within a 14-day bioconversion process. The compost meets standards for the nitrogen, C/N ratio, phosphorus, potassium, zinc, and iron content (SNI 19-7030-2004).
