| Summary: | With the rapid development of biodegradable plastics, the inspection and detection of degradable plastics is becoming more and more important, GB/T 19277.1 is the most commonly used degradable plastic compost detection method. However, there are some problems in this method, such as large differences among different decomposed composts, unstable compost between batches, subjective factors interfering greatly with the experimental results, and the nutrient composition of compost culture solution in vermiculite scheme is not clearly defined. In this paper, the effects of compost and vermiculite inoculants were compared by experiments. In addition, the formula of vermiculite culture solution was optimized, and the experimental results showed that the determination efficiency of product degradation rate could be effectively improved by adding specific microbial bacteria (potassium bacteria, bacillus group, lactic acid bacteria group, etc.). At the same time, the optimized culture solution formula can better control the nutrient composition, solve the problems of batch to batch instability, artificial factors, and improve the reproducibility and repeatability of detection. This is of great significance for promoting the application and development of biodegradable plastics testing standards. Through these improvements, the performance of biodegradable plastics can be more effectively assessed, the rational use of environmentally friendly materials and the control of plastic pollution can be promoted, the application of degradable materials in packaging materials, agriculture, medical care, textile and clothing, new energy and other fields can be promoted, the green transformation of the industry can also help “carbon peak” and “carbon neutral” realization. |
