Core Viewpoint - The waste incineration industry in China is experiencing a shift from an oversupply of waste to a shortage, raising questions about future operations and strategies [1][4]. Group 1: Industry Technology and Innovation - The waste incineration plant in Xi'an has a designed processing capacity of 3,000 tons per day but is currently processing only about 2,000 tons, leading to underutilization of resources [1]. - The technology used in waste incineration has significantly advanced, with a 40% improvement in thermal efficiency over the past decade, and emissions of dioxins at only 10% of EU standards [1][2]. - An automated combustion control system developed by the company adjusts the furnace speed and air volume based on waste composition, maintaining thermal efficiency above 85% and saving 1,220 tons of standard coal annually [2]. Group 2: Global Expansion and Standards - Nearly half of China's waste incineration projects have pollutant emission control levels that are world-leading, with efforts to promote Chinese standards globally [3]. - As of May 2025, Chinese companies are involved in 79 overseas waste incineration projects across multiple continents [3]. Group 3: Supply and Demand Dynamics - The average load rate of waste incineration plants in China is around 60%, indicating that 40% of capacity is underutilized, leading to financial strain on operators [4]. - In some regions, competition for limited waste resources has driven down processing fees to unsustainable levels, with some facilities accepting rates below cost [4]. Group 4: Future Directions and Service Value - The industry is exploring new avenues for waste management, including the co-processing of sludge and green waste, which can significantly increase the proportion of sludge burned [6]. - Waste incineration plants are evolving from being seen as environmental burdens to becoming urban service providers, integrating energy supply and educational initiatives into their operations [7].
