Developing a Centralized Automatic Biomass Recovery System for Zero-Food Waste in High-Rise Apartment

Abstract

An advanced waste management system has been developed specifically for high-rise residential buildings, aiming to achieve zero-food waste emissions through efficient biomass recovery. In response to the global trend of increasing high-rise construction, this system includes two main components: a food waste cutting and transfer device installed under household sinks, and a centralized automatic module located in the building’s basement. The system efficiently handles solid-liquid separation, dehydration, and bio-drying, converting food waste into high-quality biomass with low moisture content that is suitable for long-term storage. Fully automated and equipped with remote monitoring capabilities, the system ensures a sanitary and convenient environment for residents. Successfully implemented in two large-scale apartment complexes in Korea, it has operated seamlessly for over three years without causing any inconvenience to residents. Additionally, the system has encouraged greater resident participation in sustainable waste management practices, such as the separation of recyclable and special wastes in communal sorting rooms. The implementation of this integrated system is proposed as a viable technical solution for sustainable waste management in high-rise buildings, aligning with global trends in eco-friendly urban development and addressing the challenges posed by climate change.
