AB  - This study assesses present preliminary Life Cycle Inventory for rapeseed oil polyols suitable for the 
production of polyurethane, which is one of the most widely used polymer materials. Due to growing 
environmental problems, the polyurethane industry is seeking bio-based raw materials. A study was carried 
out for rapeseed oil triethanolamine polyol developed at Latvian State Institute of Wood Chemistry. The 
cradle-to-gate study was carried out with functional unit of 1 kg rapeseed oil polyol synthesized in a scaled-up 
pilot reactor. The results show that at the midpoint level the production of rapeseed oil has the highest impact 
in the following environmental impact categories: agricultural land occupation with 59%, followed by climate 
change (human health) with 12%, fossil depletion with 8% and climate change (ecosystems) with 8%.
