Biodegradability of PLA and tea waste composites based on "cHAMU" and the "tea waste recycling system"

This paper proposes and explains the concept of "Chinese Pinyin of tea and wood (CHAMU)" and the establishment of the "Tea Waste Recycling System" for mitigating the problem of tea waste disposal in the tea production process. Based on the "reuse of fully biodegradable waste" proposed in the "Tea Waste Recycling System," this paper investigates existing biodegradation studies related to plant materials and analyzes the factors that contribute to the degradation of plant material. This paper analyzes the composition of tea waste and establishes a theoretical basis for the biodegradation of tea waste. The soil-buried method was used to test the degradation performance of samples prepared from polylactic acid (PLA) and tea waste composites made by injection molding.This paper mainly focuses on the experiment and discussion of the biodegradability of "CHAMU" materials and considers a theoretical basis to assist in the establishment of a tea waste recycling system.
