Recycling of coffee pulp by Hermetia illucens (Diptera: Stratiomyidae) larvae
AbstractThe digestion of coffee pulp by larvae of the soldier fly Hermetia illucens (L.) was studied in a small-scale experiment to obtain preliminary data pertaining to this method of treating the waste. After 13 days the coffee pulp was converted into a slurry-like material and lost 29·8% of the initial dry matter, the pH increased from 7·6 to 8·85, the odour was reduced significantly, and the total weight of larvae was 6·2 times that at the beginning. It was concluded that H. illucens larvae could be utilized in recycling coffee pulp under controlled conditions.
