Impact of Compost Produced with Coffee Pulp and Hermetia Illucens on Tomato Plant Growth.
This study evaluated the bioconversion of coffee pulp by Hermetia illucens larvae in a controlled reactor designed to regulate temperature (27–30 °C), relative humidity (60–70%), and aeration. The system monitored environmental temperature, relative humidity, CO2 concentration, and substrate tempera...

| description | This study evaluated the bioconversion of coffee pulp by Hermetia illucens larvae in a controlled reactor designed to regulate temperature (27–30 °C), relative humidity (60–70%), and aeration. The system monitored environmental temperature, relative humidity, CO2 concentration, and substrate temperature. The substrate—coffee pulp with 82.67% moisture, pH 5.32, and 38.58% total organic carbon—was supplied at 1 kg per container with 100 larvae (feeding rate: 115.53 mg dry matter/larva/day), with three replicates and a control without larvae. Larval growth was monitored for 15 days. The highest mass (0.133 ± 0.007 g) and length (18.0 ± 0.42 mm) were observed on day 14. CO2 concentration peaked at 5553 ppm on day 10, while environmental conditions remained stable throughout the experiment.
The resulting compost exhibited a pH of 9.71, density of 0.53 g/cm³, and 36.04% total organic carbon. The fertilizer was tested in germination assays using Solanum lycopersicum (tomato) seeds and coconut coir in various ratios. The 1:3 frass-to-coir treatment yielded the best plant performance: 96 cm height, 23 mm stem thickness, 14 leaves, and 86.67% germination over 27 days. These results demonstrate that black soldier fly larvae can effectively bioconvert coffee pulp into a nutrient-rich organic fertilizer suitable for early-stage plant development, supporting its potential application in sustainable agriculture. |
