Core Viewpoint - The waste incineration industry in Sichuan is currently operating at full capacity, with most facilities managing to process the waste generated without significant shortages, unlike other regions in China where waste scarcity is a growing concern [3][8]. Current Situation - Chengdu has nine waste incineration plants operating at full capacity, processing over 15,800 tons of waste daily, while the city generates approximately 20,000 tons of waste each day [5][6]. - The Chengdu Wanjing Environmental Power Plant (Phase II) has been operational for over 1,600 days, processing more than 3,000 tons of waste daily and generating around 1.5 million kWh of electricity [5]. - Other cities in Sichuan, such as Suining and Meishan, report stable operations with sufficient waste supply, while Dazhou faces a shortfall of about 400 tons daily [7][8]. - By the end of 2024, Sichuan is expected to have 45 waste incineration plants with a daily processing capacity of 48,000 tons, handling an average of 43,500 tons of waste daily [7][8]. Reasons for Current Situation - Sichuan's population of 83.68 million contributes to a high waste generation rate, with approximately 20.84 million tons of waste produced in 2023 [9][10]. - The province has strategically planned its waste incineration capacity, with 45 operational plants compared to the 37 planned in 2022, ensuring that supply meets demand [10]. Effectiveness - Technological advancements have significantly improved waste-to-energy conversion, with the energy generated from one ton of waste increasing from 200 kWh a decade ago to approximately 500 kWh today [11][12]. - AI algorithms are being integrated into waste incineration processes to optimize combustion parameters, enhancing energy recovery by 10% per ton of waste [12]. - The waste incineration process reduces waste volume by over 80%, with byproducts being repurposed for construction materials and ensuring emissions meet national standards [11][12].

Core Viewpoint - The article highlights the transformation of municipal solid waste into clean energy at the Changsha Black Mifeng Solid Waste Treatment Plant, showcasing advanced technology and environmental benefits. Company Overview - The Changsha Black Mifeng Solid Waste Treatment Plant, operated by Hunan Junxin Environmental Protection Co., Ltd., is the only environmental park in China to have received two Luban Awards, the highest construction engineering award in the country [2]. - The plant has a daily waste processing capacity of nearly 20,000 tons of municipal solid waste and over 1,000 tons of sludge, generating approximately 5 million kilowatt-hours of electricity daily, sufficient to meet the needs of 1.37 million urban residents [2]. Technological Advancements - The facility employs a 5G cloud platform for visual detection and traceability of waste, achieving a 99.8% automation rate across the plant [4]. - Real-time monitoring of key equipment performance and emissions is conducted, with all emission indicators significantly exceeding national and EU standards [4]. Environmental Impact - The plant contributes to significant carbon reduction, achieving over 1 million tons of carbon emissions reduction annually [2]. - The waste classification system in Changsha aims for a recycling rate of 41.47% and a resource utilization rate of 86.60% by 2024, with a 100% harmless treatment rate [6]. Waste Management Strategy - The city focuses on source reduction, recycling, community education, and facility openness to enhance waste classification efforts [6].
