- Introduction
- The GB/T 42764-2023 standard, titled "Assessment of the Inherent Aerobic Biodegradability of Plastics Exposed to Marine Seeding Materials under Laboratory Conditions at Ambient Temperature - Test Method and Requirements," provides guidelines for evaluating the biodegradability of plastic materials in laboratory settings under simulated marine conditions. This standard aims to assess the inherent ability of plastics to undergo aerobic biodegradation in the presence of marine seeding materials at ambient temperature. The test method outlined in this standard involves subjecting plastic samples to controlled conditions, including exposure to marine organisms and monitoring their biodegradation over a specified period. The evaluation criteria specified in the standard help determine the extent of biodegradation based on various parameters such as carbon dioxide production, degradation rate, and visual observations. This standard is essential for assessing the environmental impact of plastics in marine environments and promoting the development of more sustainable plastic materials. By providing a standardized approach for evaluating biodegradability, GB/T 42764-2023 contributes to the advancement of eco-friendly plastic materials and supports efforts to mitigate plastic pollution in oceans.
