AbstractProcessing organic waste using black soldier fly (BSF)-based technology offers a promising alternative for sustainable organic waste management and urban sanitation. This study was conducted to assess the influence of feeding strategies on the efficacy of BSF larvae to recycle organic wastes into value products. Fruit waste and chicken manure were used as organic waste samples while commercial chicken feed was used as a control, and were processed for 15 days in circular plastic containers (Ø 30 × 12 cm) with 50; 100; 150; and 200 mg/larva/day continuous and batch feeding diets, using 500 four-day-old larvae per diet, repeated four times. Larval survival rates were not significantly affected by the feeding strategies. However, average larval biomass of 83.69 ± 13.04 g and 82.46 ± 08.52 g was achieved for the continuous and batch feeding strategies, respectively, under favorable conditions. Larval feed reduction rates ranged from 24.65 ± 03.48% to 72.78 ± 01.48% and 24.52 ± 0.27% to 72.25 ± 12.13% with continuous and batch feeding strategies, respectively, and were significantly affected by the different daily diets. On the other hand, the bioconversion rates ranged from 13.34 ± 0.26% to 50.82 ± 02.27%, and the highest values were observed with the continuous feeding diets. This study confirms the efficacy of BSF larvae to thrive in different organic substrates and shows that the continuous feeding strategy can be better and enhance a sustainable small-scale organic waste management.

Resource Input

North America is a big consumer and consequently a big producer of waste. For the purpose of this project, we were primarily interested in collecting information in North America, focusing on Quebec primarily. The main research question was risen up during the fieldwork and assistance with the Canadian company. It clearly presents the enterprise readiness for obtaining a smart solution on organic/food waste problem. It is believed, how organic/food waste can be a resource of a high value. There is a capacity of creating a new path, where organic/food waste could become the important as plant/field nutrient supply. The circular approach to organic waste management is urgently needed in a way how the organic waste should be reduced and returned as productive resource input into our economy. The paper presents a new value towards a sustainability process that Canada is building at the moment. It represents the innovative approach, which is highly accepted in some cities in Quebec with the obtained pilot projects and excellent results. This paper is not only a simple research paper, but it is also the very important original innovative document which can be highly used on the level of each municipality, region and federal level.
