The Premium and Absorbent sorbents saturated with transformer oil not containing radionuclides were used as model RAW systems. It was established that pressure-assisted thermomechanical consolidation leads to the formation of a denser structure and a reduction in hydrocarbon-phase losses compared with thermal treatment without applied pressure. For Premium, mass losses decreased from 0.74 to 0.35 g (by 53%), and for Absorbent, from 0.75 to 0.47 g (by 37%), and the consolidated samples were characterized by a more homogeneous microstructure and increased resistance to exudation. It was established that the efficiency of hydrocarbon-phase retention is determined by both the treatment conditions and the mineral composition of the sorbent. The obtained results indicate the prospects of low-temperature pressure-assisted thermomechanical consolidation at a temperature of 150 \u00b0C, a pressure of 1.5 MPa, and a holding time of 20 s for the conditioning of oil-containing RAW without the use of additional binding components.<\/jats:p>","DOI":"10.3390\/ma19183893","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T10:19:41Z","timestamp":1789381181000},"page":"3893","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Low-Temperature Thermomechanical Consolidation of Aluminosilicate Sorbents Impregnated with Model Oil-Containing Radioactive Waste"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4675-1067","authenticated-orcid":false,"given":"Yerbolat","family":"Koyanbayev","sequence":"first","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7627-8752","authenticated-orcid":false,"given":"Viktor","family":"Baklanov","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4189-6539","authenticated-orcid":false,"given":"Nuriya","family":"Mukhamedova","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"},{"name":"Research School of Physical and Chemical Sciences, Shakarim University, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2188-8075","authenticated-orcid":false,"given":"Arman","family":"Miniyazov","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"},{"name":"Research School of Physical and Chemical Sciences, Shakarim University, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7665-4022","authenticated-orcid":false,"given":"Igor","family":"Sokolov","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"}]},{"given":"Dilyara","family":"Belgibayeva","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"},{"name":"Research School of Physical and Chemical Sciences, Shakarim University, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5740-9331","authenticated-orcid":false,"given":"Ospan","family":"Oken","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4694-2200","authenticated-orcid":false,"given":"Aisara","family":"Sabyrtayeva","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"validation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3436-2055","authenticated-orcid":false,"given":"Anel","family":"Raiko","sequence":"additional","affiliation":[{"name":"National Nuclear Center of the Republic of Kazakhstan, Kurchatov 071100, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,12]]},"reference":[{"key":"ref_1","unstructured":"IAEA (2017).
