垃圾不够烧？变化如何发生的

Core Viewpoint - The rapid increase in waste incineration capacity in China is a significant advancement in the waste management industry, with many cities achieving zero landfill for original household waste and beginning the excavation of aged landfill waste for secondary treatment [1][19]. Group 1: Waste Management Progress - The implementation of waste classification and the encouragement of incineration plant construction have led to a notable improvement in waste management capabilities across China [1]. - The excavation of aged landfill waste is primarily driven by the need to manage the ash produced from incineration, as policies restrict the expansion of landfill areas [1][20]. - The shift from "waste siege" to "zero waste cities" reflects the heavy burden of waste management in China, with a historical reliance on imported waste materials [3][4]. Group 2: Waste Classification and Incineration - The introduction of mandatory waste classification aims to optimize waste processing by separating recyclable materials and hazardous waste, which enhances incineration efficiency [8][9]. - In Shanghai, the implementation of waste classification has resulted in a 20% reduction in the amount of combustible dry waste available for incineration, despite an increase in the overall recycling rates [10][12]. - The number of waste incineration plants is increasing, with a goal to have 80 million tons of daily incineration capacity by 2025, reflecting a significant investment in waste-to-energy infrastructure [14][16]. Group 3: Market Dynamics and Challenges - The rapid expansion of incineration capacity has led to reports of a "garbage shortage," prompting some regions to excavate old landfill waste to meet processing needs [19][20]. - The industry faces challenges such as subsidy reductions and stricter environmental regulations, which may lead to a market reshuffle and the closure of smaller, less efficient plants [25][26]. - Major companies are seeking to expand their market presence and improve operational efficiency through technological innovation and strategic partnerships, both domestically and internationally [27][28].
