Utilization Of Black Soldier Fly Technology to Livestock Production: A Biowaste Processing Case Study in Brgy. Paliparan, Calauan, Laguna, Philippines

Abstract

This case study assesses the utilization of Black Soldier Fly (BSF) Technology in livestock production and the utilization in biowaste processing, significantly in a pilot farm located at Brgy. Paliparan, Calauan, Laguna. Whereof, the purpose of this study is to utilize BSF technology as an alternative resource in addressing the high price of feed meals in the market and significantly addressing the emerging environmental pollution caused by 931 million tons of biowaste causing 3.3 billion tons of carbon dioxide (CO2) that releases into the atmosphere every year (Cheapa Waste, 2022). During visitation and observation of the researcher at the farm, the BSF technology has 44 to 45 days to live to complete its life cycle. Each cycle has a different function, before the BSF turns into an adult (with 6 legs, two wings, and without a stinger or mouth) it traverses the larvae and pupae stage. Wherein, the larvae stage has 21-28 days to live, and this stage is useful for waste management. While the pupae stage has 13-15 days to live, which is utilized for feed meal production and oil extraction. Thereafter 3 days from this pupae stage, it emerges into a BSF adult. This adult stage has only 5 to 8 days to live including mating and hatching of their eggs, after this event this BSF will automatically die. At the pilot farm, the BSF eggs will be collected and transferred to a bin, this bin will be located in a separate room having 25-29ºC. Once, this egg becomes larvae, these larvae will be transferred to a biopond to eat and consume all nutrients they need. There are four types of Biopond on the farm, F1 classify as high nutrients containing Soya, tofu, gelatin, and milk, F2 classify as common nutrients containing Vegetables, kitchen waste, doughs, bread, and fruits, F3 classify as average nutrients containing 50% of F1 and F2 and 50% of F4. Finally, F4 classify as a good source of protein containing only meat. The maximum utilization of BSF in biowaste management is depending on these food classifications allocated at the bioponds. Because the softer the food the faster they can eat. In addition, temperature and humidity have a great impact on the utilization. Based on analyses, 1k of BSF eggs will be equivalent to 3,000,000 pcs of larvae on average wherein can eat or consume 111. 76 kg of biowaste per day or 18,774. 84 per year including the 30% mortality rate deducted from the total number of BSFL. On the other hand, only 20% to 10% of the total number of BSFLs can only be used for livestock production. Therefore, this case study determines the effectiveness of BSF utilization in biowaste and livestock production, indicating that BSF technology is certainly effective as an alternative feed meal for livestock production, likewise in addressing biowaste effluence. However, due to the insufficient number of BSF technology available at the farm, it cannot be used in the same approach without considering the mortality rate and the methods utilized in feeding and harvesting BSF larvae including the methods in the rearing facility.
