The symbiotic relationship between Tenebrio molitor and coffee grounds presents an innovative perspective on addressing global challenges

Abstract

This study unveils a novel approach toward sustainable protein production and waste management by investigating the utilization of coffee grounds as a nutrient source for Tenebrio molitor larvae. This research is a pioneering exploration in response to pressing protein shortages, food waste, and food security challenges. The study employs an entirely randomized experimental design, comprising five treatment groups and one control group; each replicated thrice. Notably, the study amalgamates cutting-edge data mining techniques through the Scopus database to elucidate the existing research landscape around Tenebrio molitor. This exploration underscores the insect's pivotal role as a prospective alternative protein source. The experimental findings, a core contribution, discern that T1, a blend of 5% coffee grounds and 95% substrate, yields the most significant mass gain in larvae over the initial 7-day phase, surpassing the control group. However, an intriguing revelation follows: specific treatments experience subsequent weight loss, emphasizing the significance of strategic larval harvesting and processing. These collective results underscore Tenebrio Molitor's potential as an innovative protein source while spotlighting coffee grounds as a valuable larval growth catalyst. This study forges a path towards sustainable protein solutions, elucidating the dynamic interplay between Tenebrio molitor, coffee grounds, and their promising role in addressing food security concerns, particularly in socioeconomically challenged regions.
