Optimization of Nativo Wood Fibre Insulation Board Through LCA Analysis

Abstract

A previous LCA study on the insulation products has led to some uncertainty on the resulting Environmental Product Declaration (EPD) certification obtained by Hunton Fiber AS in Norway. There are certain themes included in the existing LCA which contain larger uncertainties than others. The bulk of uncertainties are related to allocation of impacts stemming from the phase of extraction and production of raw materials (A1), impacts from the transportation of raw materials (A2) and impacts of different scenarios of waste processing (C3). Goal of this study is to address these uncertainties by investigating (i) different scenarios for allocation of impacts from raw materials (wood chips), (ii) the impact of different modes of transportation of raw materials and (iii) different waste treatment scenarios. A comparative analysis of different LCA scenarios was assessed focused on the product’s impact on climate change and results are taken by the company as useful suggestions for future decisions.
