Abstract: Bioproducts have attracted much attention in recent years due to the increasing environmental concerns about petroleum products. In this study, we aimed to explore potential environmental impacts and economic feasibility of pressure sensitive bio-adhesive (PSA) produced from the reversible addition-fragmentation chain transfer polymerization process. A detail process model of pressure sensitive bio-adhesive was developed in order to thoroughly understand both economic and environmental impacts of this production process. Life cycle assessment results showed that the overall environmental impacts of bio-adhesive was ~30% lower compared to the petro-adhesive’s production process. The minimum selling price for this pressure sensitive bio-adhesive was calculated as $3.48/kg. Sensitivity analysis results indicated that raw materials costs had the most significant impact on pressure sensitive bio-adhesive’s selling price, followed by total capital investment. Electricity sources had larger environmental impacts to the overall bio-adhesive production process compared to transportation distance and product yield. These results highlight the environmental advantage and potential economic competency of this pressure sensitive bio-based adhesive.
