Abstract: Taking the municipal solid waste containerized inland waterway transport system in Shanghai as an example, the technical upgrade for the vertical baler system at a transfer station was carried out. The original station utilized a horizontal compression process, which was converted to a vertical compression system in 2017 to meet waste classification requirements. The modified baler system initially experienced severe waste scattering and container leakage during operation. By optimizing the chute structure, enhancing sealing performance, and improving the loading and compression process, the issue of waste scattering was effectively resolved, leading to a significant improvement in the on-site working environment. Post-improvement operational data indicated that the score for the degree of waste scattering on the first-floor ground had reduced by 75%, the score for carry-over and leakage from dry waste containers had decreased by 82%, and the kitchen waste containers had achieved zero carry-over and zero leakage. Additionally, the operating costs for the equipment at a single set of the loading berths have been reduced by 56%. These outcomes demonstrated a dual enhancement in both environmental benefit and economic benefit, providing a practical reference for the technical transformation of similar transfer stations.
