The effects of the feedstock composition (each material alone and all possible binary combinations) and the reaction medium (deionised water, seawater and all possible binary mixtures) have been evaluated at 350 °C and 170 bar over a wide range of reaction times (20–180 min). Bilateral biomass-plastic synergistic and antagonistic interactions between both feedstocks, combined with several promoting and inhibiting effects displayed by seawater, ruled the distribution of the reaction products and their most important physicochemical and fuel properties. Process optimisation revealed that the formation of an energy-dense (32 MJ/kg) liquid biofuel was maximised (26% biocrude yield) by conducting the process with almond hulls in deionised water for 115 min. At the same time, face masks promoted solid biofuel formation (83% hydrochar yield, 46 MJ/kg) by coprocessing an almond hulls/disposable face masks mixture (8:92 wt%) in salted (seawater/deionised water mixture with 37471 ppm salinity) water for 180 min. Conducting the process with seawater (44608 ppm salinity) for 180 min allowed coprocessing of both materials (22/78 wt% almond hulls/face masks) efficiently to maximise biofuels production (13% biocrude yield, HHV = 33 MJ/kg and 67% hydrochar yield, HHV = 49 MJ/kg). These results are a breakthrough in developing season-free and flexible biorefineries, which contribute to reducing pollution and bringing out the hidden value of human activity common residues. 000119010 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/IJC-2018-037110-I$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-115053RB-I00/AEI/10.13039/501100011033$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/ENE2017-83854-R 000119010 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000119010 590__ $$a15.1$$b2022 000119010 592__ $$a2.803$$b2022 000119010 591__ $$aENGINEERING, ENVIRONMENTAL$$b3 / 55 = 0.055$$c2022$$dQ1$$eT1 000119010 591__ $$aENGINEERING, CHEMICAL$$b5 / 141 = 0.035$$c2022$$dQ1$$eT1 000119010 593__ $$aChemical Engineering (miscellaneous)$$c2022$$dQ1 000119010 593__ $$aIndustrial and Manufacturing Engineering$$c2022$$dQ1 000119010 593__ $$aEnvironmental Chemistry$$c2022$$dQ1 000119010 593__ $$aChemistry (miscellaneous)$$c2022$$dQ1 000119010 594__ $$a21.5$$b2022 000119010 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000119010 700__ $$aZapata, Gonzalo 000119010 700__ $$0(orcid)0000-0002-0922-5615$$aOriol, Luis$$uUniversidad de Zaragoza 000119010 700__ $$aPinilla, José Luis 000119010 700__ $$aSuelves, Isabel 000119010 7102_ $$12013$$2765$$aUniversidad de Zaragoza$$bDpto.
