COCOSMART: A Circular Economy–Driven Automated Cocopeat and Coco Fiber Sieving System for Sustainable Resource Recovery, Waste Time Reduction, and IoT-Based Production Monitoring

This study presents COCOSMART, a circular economy–driven automated cocopeat and coco fiber sieving system designed to enhance resource recovery, improve processing efficiency, and support sustainable agricultural practices in coconut-producing communities. Coconut husk, commonly treated as agricultural waste, contains valuable materials such as cocopeat and coir fiber that can be converted into high-value products for agricultural and industrial applications. The proposed system integrates a vibration-based sieving mechanism, load cell weight monitoring, and Internet of Things (IoT) technology using Arduino and ESP8266 modules for real-time production tracking and data logging.

The system was evaluated through experimental trials using 1 kg, 2 kg, 5 kg, and 10 kg input loads. Results showed high operational reliability, with a recovery efficiency of 92–96%, weight measurement accuracy of 97–99%, and material loss reduced to 4–8%. Additionally, the system achieved a 50–65% reduction in processing time compared to traditional manual methods, demonstrating significant improvements in productivity and labor efficiency.

Beyond technical performance, the study demonstrates strong alignment with circular economy principles by converting agricultural waste into useful outputs, thereby promoting waste valorization and resource efficiency. Furthermore, the system supports key sustainability policies, including Republic Act No. 9003 on ecological solid waste management and the Coconut Farmers and Industry Development Plan (CFIDP), by enabling waste diversion, value-added processing, and agricultural modernization.

Overall, COCOSMART provides a scalable and sustainable solution for coconut processing industries, integrating automation, IoT, and policy-driven circular economy strategies to improve resource recovery and rural economic development.
