Core Viewpoint - The implementation of the national standard GB/T 35795 for fully biodegradable agricultural ground cover films is significantly promoting the production, application, and regulation of biodegradable films in China, contributing to agricultural green development and soil environmental protection [3][4]. Group 1: Current Status and Application - The annual coverage area of biodegradable films in China has approached 3 million acres, with applications across more than 20 provinces, covering various crops such as corn, tomatoes, and rice [1]. - The use of biodegradable films has effectively addressed residual film pollution and increased crop yields, particularly benefiting root crops and rice by reducing costs associated with herbicides [1][2]. Group 2: Industry Development and Support - The biodegradable film industry has received strong support from multiple government departments, leading to significant advancements in application experience and pollution management [2]. - The annual usage of agricultural films in China exceeds 1.45 million tons, with a total covered land area of 250 million acres since the promotion of film usage in the 1980s [1]. Group 3: Standard Implementation and Innovation - The implementation of the GB/T 35795 standard has led to rapid growth in the promotion area of biodegradable films, transitioning from pilot projects to large-scale applications, especially in northern arid regions [3]. - The standard has driven continuous innovation in materials and production processes, establishing a comprehensive innovation system from raw material synthesis to end-use applications [3]. Group 4: Challenges and Future Directions - Some challenges have been identified in the standard's implementation, including the need for better alignment with international standards and the establishment of traceability to combat counterfeit products [4]. - A revision plan for the standard has been approved, with discussions ongoing to refine various aspects, including technical indicators and testing methods, aiming for a draft for public consultation by mid-August [4].
