Standard formulation background and technology evolution analysis
Background:With the increasing severity of global plastic pollution, the research and development and promotion of biodegradable materials have become the focus of global attention. The formulation of GB/T 32366-2015 fills the domestic standard gap in the field of polybutylene terephthalate-adipate (PBAT), and provides a technical basis for promoting the development of my country's biodegradable materials industry.
Implementation Suggestions
- Enterprise side: Strictly follow the standards for raw material procurement, production process control and quality inspection to ensure that products meet the requirements of GB/T 32366-2015.
- Policy level: It is recommended that the government strengthen the publicity and supervision of standards, promote the application demonstration projects of biodegradable materials, and establish a sound market promotion mechanism.
- Technical improvement: Encourage enterprises to develop PBAT materials with higher degradation efficiency and lower environmental impact to enhance product competitiveness.
