A screening Life Cycle Assessment (LCA) of tall oil-based bio-polyols suitable for rigid polyurethane (PU) foams has been carried out.The goal was to identify the hot-spots and data gaps.The system under investigation is AEG CGB6130ACM 60cm Gas Cooker – Stainless Steel three different tall oil fatty acids (TOFA)-based bio-polyol synthesis with a cradle-to-gate approach, from the production of raw materials to the synthesis of TOFA based bio-polyols at a pilot-scale reactor.

The synthesis steps that give the Extra Handsets most significant environmental footprint hot-spots were identified.The results showed the bio-based feedstock was the main environmental hot-spot in the bio-polyol production process.Future research directions have been highlighted.
