Core Viewpoint - The article discusses the phenomenon of "insufficient garbage supply" in China's waste incineration power generation industry, highlighting the transition from "garbage siege" to "garbage scarcity" and the challenges faced by incineration plants due to overcapacity and reduced waste generation [2][3][4]. Group 1: Industry Overview - In the past two decades, China has transformed its waste management approach, with the proportion of urban household waste treated by incineration rising from 9.8% in 2005 to 82.5% in 2023, while landfill treatment dropped from 85.2% to 7.5% [2]. - The number of waste incineration plants has increased from 67 to 1010, with an average capacity utilization rate of around 60% in recent years [3][4]. - The daily incineration capacity of waste has surged from 23.8 million tons in 2016 to 115.5 million tons in 2024, yet the industry average load factor remains below 60%, with 40% of capacity idle [9]. Group 2: Causes of Insufficient Garbage Supply - The insufficient garbage supply is attributed to two main factors: overestimation of future waste generation during planning and the impact of waste classification, which has diverted organic waste away from incineration [3][10]. - The construction of incineration plants has outpaced actual waste generation, leading to a supply-demand imbalance, with many plants operating at low capacity [10][11]. - The promotion of waste classification has resulted in a significant portion of waste being processed differently, reducing the amount available for incineration [11]. Group 3: Financial and Operational Challenges - The financial viability of incineration plants is increasingly challenged by the reduction of government subsidies and the need to diversify operations, such as providing steam and heat to nearby industries [4][20]. - The revenue structure of incineration plants relies heavily on government subsidies, which have been declining, leading to increased pressure on local governments to cover rising waste disposal fees [19][21]. - The average waste disposal fee has risen significantly, with some regions charging up to 150 yuan per ton, increasing the financial burden on local governments [23][24]. Group 4: Future Trends and Adaptations - The industry is expected to adapt by exploring new business models and expanding services beyond waste incineration, such as heat supply and sludge treatment [4][25]. - The article suggests that the industry must focus on improving economic efficiency and diversifying revenue sources to cope with the challenges of insufficient waste supply and subsidy reductions [25].
