生物降解塑料袋新国标明年实施 标识、降解率等全面升级

Core Viewpoint - The new national standard for biodegradable plastic shopping bags in China aims to enhance product identification, improve degradation performance, and clarify producer responsibilities, with an expected market growth in production capacity and a significant reduction in traditional plastic bag usage by 2025 [1][12]. Group 1: Market Growth and Production - The production capacity of biodegradable plastic shopping bags in China has seen a compound annual growth rate exceeding 20% over the past five years [12]. - By 2025, the total market production is expected to reach approximately 550,000 tons, replacing around 20 billion traditional plastic bags annually, leading to a significant decrease in the overall usage of traditional plastic shopping bags [1][12]. Group 2: New National Standard Implementation - The new national standard for biodegradable plastic shopping bags was recently released and will be officially implemented on January 1, 2027 [1]. - The standard includes clearer labeling requirements, specifying the composition and degradation conditions of the bags, making it easier for consumers to identify biodegradable products [4][6]. Group 3: Enhanced Degradation Performance - The new standard increases the required degradation rate from 60% to 90%, ensuring that bags decompose effectively under various conditions [7]. - Under industrial composting conditions, bags must achieve 90% degradation within a maximum of 180 days, while in soil and marine environments, the same degradation rate must be achieved within two years [7]. Group 4: Producer Responsibilities and Storage Requirements - The new standard emphasizes producer responsibility, allowing manufacturers to determine and clearly indicate the appropriate storage period for biodegradable plastic shopping bags based on their performance and user needs [12]. - The previous requirement for a minimum storage period of one year has been revised to allow for flexibility based on different usage scenarios [12].
