从饮料瓶到饮料瓶：rPET助力绿色循环新图景

Core Insights - The recycling of food contact plastics, particularly the use of recycled PET (rPET) bottles, is recognized as a significant direction for environmental benefits and a crucial pathway for achieving high-quality green development [1][2] Group 1: Recycling and Environmental Impact - China's PET bottle recycling rate is between 96.48% and 97.63%, which is at an internationally advanced level, but most recycled materials are used in non-food sectors [1] - The "same-level recycling" model for PET has been successfully applied internationally, extending the lifecycle of PET and significantly reducing carbon emissions throughout its lifecycle [1] Group 2: Safety and Standards - The EU and the US have established comprehensive safety assessment and approval systems for food-grade rPET, primarily validated through "challenge tests" that simulate extreme contamination scenarios [1] - Domestic research institutions in China are conducting verification studies, showing that standardized domestic rPET recycling processes can meet food safety requirements [1] Group 3: Consumer Acceptance and Education - Over 60% of consumers support the use of rPET in food packaging, and awareness of its benefits in energy saving and resource recycling increases their willingness to pay [2] - Continuous scientific communication and public education are essential for enhancing societal recognition and acceptance of rPET [2] Group 4: Policy and Industry Development - China is the largest producer and consumer of PET bottles globally, yet the same-level utilization of rPET has not been realized [3] - Calls have been made for a clear management mechanism for the production and application of food-grade rPET to eliminate policy bottlenecks and promote high-quality industry development [3] - Currently, food-grade rPET produced in China is primarily exported, leading to resource wastage, as some rPET bottles return through cross-border e-commerce [3]
