Development of Eco-Industrial Design Through Production Process Efficiency and Waste Utilization at Coffee Processing Industry

Abstract

Coffee production has steadily increased each year, leading to rapid growth in the coffee industry. However, this growth has also brought challenges, particularly concerning managing generated waste in processing. The coffee processor faces significant waste management issues associated with green bean processing. To address these challenges, this study focuses on implementing the eco-industry concept, emphasizing process efficiency and waste minimization. Production efficiency is enhanced through the standardization of operations, achieved by developing standard operating procedure (SOP) documents for green bean production. Simultaneously, waste reduction strategies are employed by repurposing wet coffee pulp waste as feed for Black Soldier Fly (BSF) larvae and utilizing dry coffee pulp waste to produce briquette products. The trials of SOP implementation have demonstrated an increase in yield, reaching 15.10% for the natural process and 14.72% for the washed process, indicating improved production efficiency. Using coffee pulp waste as maggot feed has proven effective, degrading approximately 9.9kg of waste per g of maggot egg. Similarly, converting dry coffee pulp waste into briquettes has yielded products meeting quality standards, boasting a calorific value of around 6000cal/g. These initiatives not only enhance product value but also significantly reduce waste output, contributing to sustainable practices within the coffee industry.
