Core Viewpoint - The article discusses the transformation of waste management in China, highlighting the shift from a "garbage siege" to a situation where waste incineration plants are struggling to find enough garbage to process, leading to a competitive environment for waste collection and management [4][10][20]. Group 1: Industry Overview - Ten years ago, the issue of "garbage siege" was prevalent, but now it is widely recognized that there is not enough waste to incinerate in China [4][10]. - China has nearly half of the world's waste incineration plants, with over 1,010 facilities, making it the leader in waste incineration capacity globally [11][20]. - The average load rate of waste incineration plants in China is about 60%, indicating that 40% of capacity is underutilized [9]. Group 2: Market Dynamics - Waste incineration plants are resorting to extreme measures to secure waste, including paying kickbacks to property companies for waste collection [6]. - There is a trend of reopening landfills to excavate buried waste, with cities like Guangzhou and others participating in this underground competition [8]. - The number of planned shutdowns for waste incineration plants in 2023 reached 83,467 days, indicating significant operational challenges [9]. Group 3: Historical Context - The turning point for China's waste incineration industry was in 2003 when the government shifted to a model allowing private investment and operation [14]. - Policies promoting waste incineration have been introduced over the years, including increased subsidies for renewable energy projects and stricter pollution control standards [15][16]. - The rapid growth of waste incineration facilities has led to significant advancements in waste management technology and capacity [17][18]. Group 4: Future Opportunities - With domestic waste generation insufficient to meet the operational capacity of incineration plants, companies are looking abroad for opportunities [22]. - Chinese waste incineration companies have successfully established over 50 projects overseas, particularly in Southeast Asia and the Middle East [24]. - Advanced technologies developed in China for waste incineration, such as the FAST process for treating fly ash, are gaining international recognition and application [25].

Core Viewpoint - The article discusses the transformation of the waste incineration industry in China, highlighting the shift from a "garbage siege" to a situation where there is insufficient waste to meet the operational capacity of incineration plants, leading to a competitive environment for waste collection and processing [4][15][33]. Group 1: Industry Overview - Ten years ago, the issue of "garbage siege" was prevalent, but now it is widely recognized that there is not enough waste to incinerate in China [4][15]. - The number of waste incineration plants in China has reached approximately 1,010, accounting for nearly half of the global total, with over 2,100 incineration plants worldwide [17][29]. - The average load rate of waste incineration plants in China is about 60%, indicating that 40% of capacity is underutilized [10][29]. Group 2: Market Dynamics - Waste incineration plants are competing fiercely for waste, with reports of facilities paying "introduction fees" to property companies for waste collection [5][9]. - Some cities are even reopening landfills to excavate buried waste, indicating a desperate need for more waste [7][8]. - The rapid increase in the number of incineration plants has led to a decline in the number of landfills, as incineration becomes the preferred method of waste management [31][33]. Group 3: Historical Context and Policy Impact - The shift in waste management policy began in 2003, transitioning from government responsibility to a model encouraging private investment through BOT (Build-Operate-Transfer) schemes [20][21]. - Various supportive policies have been introduced over the years, including increased subsidies for renewable energy projects and stricter pollution control standards, which have facilitated the growth of the waste incineration industry [21][22][29]. Group 4: Future Prospects and International Expansion - Despite achieving a 100% harmless treatment rate for waste, new incineration projects continue to emerge, with 55 new projects added in 2023 [30][29]. - As domestic waste generation declines, Chinese waste incineration companies are beginning to explore international markets, with over 50 projects established overseas, particularly in Southeast Asia and the Middle East [38][39]. - Chinese companies are leveraging their advanced technology and complete industrial chain to compete globally, transforming waste management into a profitable venture [40][43].

Core Viewpoint - Shanghai Environment has announced the successful development of the "FAST process" in collaboration with Tongji University, marking a significant advancement in the treatment of fly ash, a major pollutant from waste incineration, which is now entering a phase of large-scale promotion [1][2] Group 1: Technology and Innovation - The FAST process utilizes existing facilities at waste incineration plants and employs principles similar to "seawater salt production" to purify certain substances in fly ash into industrial salts like sodium chloride and potassium chloride, achieving near-zero waste [2] - The technology comprises three core systems: desalination and decontamination system, salt recovery system, and synergistic thermal treatment system, which not only reduces and harmlessly processes fly ash but also creates conditions for resource utilization, converting fly ash into marketable industrial salts and aggregate [2] - The process achieves a fly ash landfill reduction rate of 95% and ensures zero discharge of wastewater and waste gas [2] Group 2: Industry Context and Impact - Fly ash is a significant secondary pollutant generated from waste incineration, containing heavy metals and dioxins, and is the largest single item in hazardous waste landfilling in China, with over 10 million tons produced annually from approximately 252 million tons of municipal waste [1] - In Shanghai, the hazardous waste landfill volume in 2023 was about 260,000 tons, with fly ash accounting for 230,000 tons, representing over two-thirds of the total [1] - The successful implementation of the FAST process provides a replicable and promotable technical pathway for achieving near-zero landfill for solid waste globally, offering a new direction for the transformation of China's waste incineration industry [2]
