A fish oil-based polyol and a castor oil (CO) were used as the bio-based raw materials. Recycled polyols were prepared by chemical decomposition of PUR flexible foam. Based on the properties of the natural and the recycled polyols, final PUR materials were designed as rigid foams or cast systems. The results showed that the fish oil-based recycled polyol was suitable for the preparation of the rigid PUR foam and can replace a majority of petrochemical polyols in the rigid PUR foam formulation without any detrimental effects on final quality of the product. The CO-based recycled polyol was used for the preparation of the compact cast PUR materials. Long aliphatic chains in this recycled polyol could be advantageously used for the formulation of flexible PUR floorings.
