Core Viewpoint - The article discusses the challenges and solutions related to noise pollution caused by garbage collection in Shanghai, highlighting the need for innovative technologies and practices to address these issues. Group 1: Noise Reduction Solutions - A 12-ton "shortened version" garbage truck has been developed, which is more efficient for urban operations due to its smaller turning radius of 6 meters compared to traditional trucks that require over 8 meters [2] - The new garbage truck is equipped with a battery from CATL, allowing for quiet operation and a cost-effective running expense of less than 1 yuan per kilometer, which is one-sixth of the cost of diesel trucks [2] - Noise issues during garbage collection arise from both the vehicle's operation and the loading/unloading processes, necessitating improvements in design to minimize mechanical noise [2][3] Group 2: Industry Consensus and Requirements - The sanitation equipment industry recognizes that to operate garbage trucks in Shanghai, they must meet requirements for new energy sources, operational efficiency, noise reduction, and prevention of leakage [3] - Companies are implementing measures such as installing anti-collision strips and improving hydraulic components to reduce noise during loading and unloading [3] Group 3: Cost and Adoption of New Energy Vehicles - The "14th Five-Year Plan" for Shanghai mandates that new or updated sanitation vehicles for waste collection and street cleaning must primarily be electric or fuel cell vehicles [4] - Currently, over 1,500 new energy sanitation vehicles are in operation, contributing to a reduction of 17,500 tons of CO2 emissions annually [4] - The adoption of new energy vehicles is hindered by high costs, as electric vehicles can cost more than double that of traditional diesel vehicles, despite some government incentives [5] Group 4: Infrastructure Challenges - Many sanitation companies lack fixed parking spaces for new energy vehicles, complicating the installation of charging stations [6] - A mobile charging vehicle has been introduced to address the charging difficulties, capable of charging electric vehicles quickly and efficiently [6] - The local government is actively working on plans to enhance parking and charging infrastructure to support the operational needs of new energy sanitation vehicles [6]
