每年减少传统塑料袋约200亿只

Core Insights - The implementation of the national standard for biodegradable plastic shopping bags has led to a significant reduction in traditional plastic bag usage, with approximately 20 billion bags eliminated annually, addressing the issue of "white pollution" from improper disposal of traditional plastic bags [1] Group 1: Environmental Impact - Over five years, the cumulative reduction in carbon dioxide emissions reached 840,000 tons, supported by the use of biodegradable materials derived from biomass or biodegradable synthetic polymers [2] - The use of biodegradable plastic bags, such as those made from polylactic acid (PLA), can reduce overall carbon emissions by 70% compared to traditional polyethylene (PE) bags [2] - The reduction in traditional plastic bag usage is equivalent to saving 1.2 million tons of oil resources [2] Group 2: Market Development - The national standard has spurred innovation in biodegradable materials, with the cost of raw materials like PLA and polyhydroxyalkanoates (PHA) decreasing by over 30% compared to traditional biodegradable plastics [3] - The production capacity of biodegradable plastic shopping bags in China is expected to grow at an annual rate of over 20% from 2020 to 2024, with total market output projected to reach nearly 500,000 tons and total market value exceeding 10 billion yuan by 2024 [3] - By 2030, the production of biodegradable plastic bags in China could reach 2 million tons, with market capacity surpassing 60 billion yuan [3] Group 3: Consumer Behavior - The usage of biodegradable plastic bags varies significantly across different retail environments, with larger supermarkets and convenience stores implementing better practices compared to some markets and small vendors that still use traditional plastic bags [4][5] - Consumer awareness and willingness to pay for biodegradable bags have increased, with over 50% of consumers now recognizing "degradable bags" [2] Group 4: Identification and Standards - Consumers can identify biodegradable plastic bags by looking for the "double J" mark, which indicates compliance with the standards set forth in the guidelines for biodegradable plastic products [6] - The "double J" mark includes information on material, degradation conditions, and product standards, promoting environmentally friendly practices [6] Group 5: Industry Outlook - The production of biodegradable plastics is on the rise, with various types being developed for applications in agriculture, packaging, catering, and daily use products [7] - The industry aims to continue focusing on recyclable, easily recoverable, and biodegradable solutions through technological innovation and coordinated efforts across the supply chain [7]
