In densely populated urban areas, where separate waste collection is impractical, waste management strategies should be structured within a sustainable framework to ensure environmental efficiency and resource optimization. High-moisture kitchen waste (KW) impairs the efficiency of incineration technology, which remains the most effective method for reducing the volume and mass of municipal solid waste (MSW). Conversely, the high proportion of readily biodegradable organics in KW makes biodrying—a process that generates heat through microbial decomposition—a promising alternative for enhancing the combustion quality of MSW. This study aims to contribute to the sustainable management of MSW by investigating the biodrying and biodegradation behaviors of KW. In the first phase, the biodrying process was evaluated through variations in temperature, mass loss, and relative humidity. The trial containing 10% bread waste (BW) reached the highest temperature (60 °C), whereas the most efficient moisture removal (43.75%) occurred under the highest airflow rate (AFR) of 3.2 m3/kg waste/day. In the second phase, respiration tests were performed to assess the biodegradation kinetics of the trials. A first-order kinetic model was applied to estimate biodegradation coefficients and maximum oxygen consumption (L). High R2 values (≥ 0.99) validated the suitability of the applied kinetic model. Such kinetic approaches may serve as promising tools for future modelling efforts in biodrying research.
