These materials include things such as bamboo, cork, hemp, and recycled plastic. The use of renewable components helps to reduce the dependence on petrochemical resources and reduce waste. Adopting these materials in various industries such as construction, packaging, and textiles can lead to a more sustainable future and decrease the carbon footprint. The presented research describes new porous polyurethane biocomposites based on used cooking oil polyol (50 per hundred polyol\u2014php) modified with cork (3, 6, 9, and 12 php). The research described here demonstrated that it is possible to replace some petrochemical raw materials with raw materials of renewable origin. This was achieved by replacing one of the petrochemical components used for the synthesis of the polyurethane matrix with a waste vegetable oil component. The modified foams were analyzed in terms of their apparent density, coefficient of thermal conductivity, compressive strength at 10% of deformation, brittleness, short-term water absorption, thermal stability, and water vapor permeability, while their morphology was examined using scanning electron microscopy and the content of closed cells. After the successful introduction of a bio-filler, it was found that the thermal insulation properties of the modified biomaterials were comparable to those of the reference material. It was concluded that it is possible to replace some petrochemical raw materials with raw materials of renewable origin.<\/jats:p>","DOI":"10.3390\/ma16083032","type":"journal-article","created":{"date-parts":[[2023,4,12]],"date-time":"2023-04-12T02:08:11Z","timestamp":1681265291000},"page":"3032","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Cork Porous Biocomposites with Polyurethane Matrix Modified with Polyol Based on Used Cooking Oil"],"prefix":"10.3390","volume":"16","author":[{"given":"Maria","family":"Kura\u0144ska","sequence":"first","affiliation":[{"name":"Department of Chemistry and Technology of Polymers, Cracow University of Technology, Warszawska 24, 31-155 Cracow, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8081-8336","authenticated-orcid":false,"given":"Mariusz","family":"Ptak","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Wroclaw University of Science and Technology, \u0141ukasiewicza 7\/9, 50-371 Wroc\u0142aw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4638-6581","authenticated-orcid":false,"given":"El\u017cbieta","family":"Malewska","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Technology of Polymers, Cracow University of Technology, Warszawska 24, 31-155 Cracow, Poland"}]},{"given":"Aleksander","family":"Prociak","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Technology of Polymers, Cracow University of Technology, Warszawska 24, 31-155 Cracow, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1451-6430","authenticated-orcid":false,"given":"Mateusz","family":"Barczewski","sequence":"additional","affiliation":[{"name":"Institute of Materials Technology, Poznan University of Technology, Piotrowo 3, 61-138 Poznan, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7809-6848","authenticated-orcid":false,"given":"Mateusz","family":"Dymek","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Wroclaw University of Science and Technology, \u0141ukasiewicza 7\/9, 50-371 Wroc\u0142aw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9751-8807","authenticated-orcid":false,"given":"F\u00e1bio A.
