摘要：竹子生长过程中吸收的二氧化碳会转移存储在竹产品中,并在产品碳足迹中以负的二氧化碳排放当量形式被扣除。目前竹产品全生命周期碳足迹研究甚少,且多集中在竹林培育经营阶段的碳固定,忽略了竹产品的碳转移和碳存储。文中简要介绍了基于生命周期评估(LCA)的碳汇计量标准,通过分析主要工程竹产品碳足迹研究结果发现:1)在LCA碳足迹评价标准中,以ISO14067和PAS2050应用最广;两者在目的和范围、抵消、数据和数据质量控制等方面相对一致,在分配和产品比较上存在不同。2)竹产品碳足迹的主要影响因素包括能源结构和加工能耗、运输方式、使用添加材料、加工工艺及产品寿命。3)因加工工艺、能源结构、分析标准和方法、功能单位、系统边界不同,不同类型竹产品碳足迹的评估结果之间难以直接比较,可以通过减少重组竹竹单板生产阶段和胶合层积竹竹条制备阶段的电力和能源消耗减少其碳足迹。4)手工竹工艺品因运输和包装中使用化石能源造成碳足迹偏高。研究结果将为双碳背景下增加产品碳封存、调控全生命周期各环节减排提供技术支撑。
The carbon dioxide absorbed by bamboo during its growth process will be later transferred and stored in bamboo products and deducted from the carbon footprint of the final products as a negative carbon dioxide emission equivalent.At present,there is little research on the full life cycle carbon footprint of bamboo products,which are mainly focused on carbon fixation in the cultivation and management of bamboo forests while ignoring the carbon transfer and carbon storage in bamboo products.This paper briefly introduces the carbon sequestration standards based on the method of life cycle assessment(LCA),and analyzes the research results associated to carbon footprint of main bamboo products.It is found:1)Among LCA carbon footprint assessment standards,ISO14067 and PAS2050 are the most widely used.They are relatively consistent in terms of purpose and scope,offset,data,and data quality control,but differ in distribution and product comparison.2)The main factors affecting the carbon footprint of bamboo products include energy structure,processing energy consumption,way of transportation,use of additive materials,processing technique and product life.3)It is difficult to directly compare the final carbon footprint of various bamboo products considering their differences in processing technique,energy structure,assessment standard and method,functional unit and system boundary.The key to reducing the carbon footprint of laminated bamboo and bamboo scrimber is to reduce the electricity and energy consumption in the production stage of the veneer for bamboo scrimber and the preparation stage of bamboo strips for laminated bamboo,respectively.4)The carbon footprint of bamboo handicrafts are relatively high due to the use of fossil energy in transportation and packaging.This study would provide technical support for increasing carbon sequestration of bamboo products and regulating emission reduction at every part of the entire life cycle in the context of“Dual Carbon”strategy.
