Using Black Soldier Fly to treat organic waste from the restaurant

Abstract

Restaurants are one of the largest organic waste sources in a region, but waste from restaurants has not been treated well, resulting in it ends directly in a landfill. Black soldier fly (BSF) treatment is an emerging technology that can turn organic waste into high-protein feed. The utilization of BSF is carried out by converting organic waste into BSF larvae. BSF larvae are an effort that can be used for recycling organic waste. Therefore, special attention is needed for the utilization of organic waste from restaurants. This study aims to determine the effectiveness of BSF larvae utilization in restaurant waste processing and observe the influence of the environment, particularly the intensity of light on the development of larvae. Organic waste from restaurants is set to a moisture content of 80%. The organic waste is used as a food source for larvae with exposure to three different lighting variants, namely 12 hours of light and 12 hours of darkness, 24 hours of darkness, and 24 hours of light. The results of this study indicated that restaurant waste could be processed with the help of BSF. Variation of light to larvae resulted in a decrease in waste by 37.77%, 37.78%, and 37.60%. The highest reduction occurred in dark lighting conditions 24 hours. Statistical tests show that light intensity has a significant effect on larvae weight.
