摘　　要：To achieve sustainable development goals,mitigate plastic pollution,and promote eco-friendly products,it is crucial to identify key products in the bamboo as a substitute for plastic(BSP)industry and assess their environmental effects.This study proposed a novel evaluation method for the environmental effect of bamboo as a substitute for plastic(EBSP).It focused on the contributions of BSP products in reducing plastic pollution and greenhouse gas emissions.We established a set of EBSP evaluation indicators and developed a grading model,evaluating 30 typical BSP products across six categories.The results showed that the EBSP evaluation model,based on the emission reduction rate of substitution(ERRS),substitution rate of material(SRM),and product renewal ratio(PRR),can accurately quantify the environmental benefits of BSP products.This model has successfully facilitated precise quantification of the EBSP and established a rational and effective grading system for BSP products.The results also demonstrated that the average EBSP ranking across the six categories of BSP products,in descending order,is:disposable bamboo products,bamboo household goods,bamboo packaging products,bamboo engineering materials,bamboo furniture products,and bamboo craft products.Specifically,disposable bamboo products scored an EBSP 1.96 times the overall average,indicating significant environmental benefits.The PRR emerged as a critical factor influencing EBSP.Among BSP products with the same lifespan,those with higher substitution emission reduction efficiency offered more pronounced environmental benefits.Ultimately,the BSP industry should strategically prioritize disposable bamboo products,such as bamboo toothbrushes,cutlery,and lunch boxes.These products should be the primary focus of policy support and central to efforts in product development,design innovation,and market promotion.
