Toxic chemicals are often used for wood preservation, but hydroxyapatite seems to be an environmentally friendly solution for wood mineralization. LCA and LCC analyses were performed on a case study of a Plečnik bench, comparing mineralized wood with a service life of 16 and 24 years to a non-mineralized reference variant. LCA was based on EN ISO 14040 and EN ISO 14044, while LCC was adapted from the European Commission’s LCC tool for public procurement. When comparing the results, mineralized wood with a service life of 24 years proved to be the most environmentally friendly and cost-effective option. The mineralized wood with a service life of 16 years had the greatest negative environmental impact, while the most expensive option was the reference woodLes je v krožnem biogospodarstvu prepoznan kot obetavna surovina, saj ima sposobnost skladiščenja ogljika, ki pa je pogojena z življenjsko dobo izdelka. Podaljšanje življenjske dobe lesa lahko dosežemo z ustrezno zaščito, pogosto z uporabo kemikalij, ki so lahko okolju in ljudem nevarne. Mineralizacija lesa s hidroksiapatitom predstavlja potencial za okolju prijazno zaščito lesa. Na primeru Plečnikove parkovne klopce, mineralizirane s hidroksiapatitom, sta bili izvedeni LCA in LCC analizi. Analiza LCA je temeljila na standardih EN ISO 14040 in EN ISO 14044, analiza LCC je bila prilagojena po vmesniku Evropske komisije za javna naročila. Pri primerjavi mineraliziranega lesa z življenjsko dobo 16 oz. 24 let z referenčnim (nemineraliziranim) lesom so rezultati pokazali, da je mineraliziran les z življenjsko dobo 24 let okolju najprijaznejša in hkrati najcenejša izbira. Največje negativne vplive na okolje je predstavljal mineraliziran les z življenjsko dobo 16 let, najdražja alternativa je bil referenčni lesTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza lesarjev Slovenije
