The Impact

Recent interest in the mass production of black soldier fly (BSF) larvae has resulted in many studies being generated. However, a majority of the studies are benchtop, or small-scale, experiments. Results generated from such studies may not translate to large-scale/industrial production. The current study was conducted at a conventional large-scale (10,000 larvae/treatment fed seven kg) to determine the impact on selected life-history traits when BSF were fed seven kg of manure (swine, dairy, or poultry) or a control diet (Gainesville diet: 50% wheat bran, 30% alfalfa meal, and 20% corn). Results showed larvae fed dairy manure took one to two days longer to develop to prepupation, with lower survivorship (45%) compared to those fed poultry or swine manure (>70%). Furthermore, the maximum larval weight was reached on day six for those fed swine manure, while other treatments achieved the maximum weight on day seven. However, larvae fed swine manure averaged 150 mg, while those fed the other diets ranged between 175 and 200 mg. Data from this study may be valuable for the industrialization of BSF. Companies using a scale varying from previously published work, including this study, should conduct pilot studies to optimize their system prior to implementation.

Biogas Yield

The aim of this study is to investigate biogas reactor designs to recover energy from swine manure and utilize that energy for a small scale pig farm in Norway. Continuous stirred tank reactor (CSTR) and upflow anaerobic sludge blanket (UASB) reactor were the design alternatives investigated. Simulations were based on the anaerobic digestion model no.1(ADM1) implemented in Aquasim software. The model was calibrated based on a series of laboratory batch reactors. The batch reactor with the highest biogas yield was first simulated to obtain the organic matter concentration in the feed manure. The resulting calibrated model was used to simulate CSTR and UASB reactors for a manure feed flow rate of 2m3/day. Different CSTR volumes in the range of 10- 60 m3 and UASB volumes in the range of 2-20 m3 were assessed using simulations. At low reactor volumes overloaded conditions were observed. Maximum energy production of 128 kWh/day at a biogas production rate of ~20 m3/day (68-71 % methane content in the biogas) was simulated for the reactor volumes for CSTR and UASB of 30m3 and 2.5m3, respectively. An efficient biogas production (e.g. to cover farm energy needs) can be obtained from a UASB reactor that can be constructed and installed at a reasonable cost.
