摘要

基于生命周期评价方法,采用Ga Bi ts软件分析1 m,3,定向刨花板（OSB）生产过程中的物料和能源消耗及环境排放。结果表明:酸化效应（AP）、光化学臭氧创造潜力（POCP）和全球气候变暖（GWP 100）是最重要的环境影响类别,分别占总环境影响值的52.1%、23.7%和20.8%;主要环境影响工序为施胶、热压成型和刨片,分别占总环境影响值的28.4%、18.0%和16.8%;而电力和胶黏剂是AP、POCP和GWP100中最关键的清单数据。

Abstract

Based on life cycle assessment（LCA）, raw material consumption, energy consumption and environment emissions during production, 1 m,3, of oriented strand board（OSB） was analyzed using Gabi ts software. Results showed that acidification effect（AP）, photochemical ozone creation potential（POCP） and global warming（GWP 100） accounted for 52.1%, 23.7% and 20.8% of the total environmental impact. The main environmental influence factors of OSB production, blending, hot pressing and stranding accounted for 28.4%, 18.0% and 16.8%. The input of power and adhesives were key inventory data that had the greatest impact on AP, POCP and GWP 100.
