However, the production process generates large amounts of waste (up to 100 tons per day), and its recycling is an important part of the oil and fat industry\u2019s economy. High-temperature processing of plant waste has proven to be a promising method for creating new materials for various industries. The aim of this study was to determine the influence of various technical parameters of carbonization (processing temperature and process environment) on the physical and chemical characteristics of materials obtained by carbonizing sunflower seed husks from the East Kazakhstan region at temperatures of 300, 400, 500, 600, 700 and 800 \u00b0C in an inert argon environment, as well as by processing the husks in an oxidizing environment at a temperature of 650 \u00b0C, for further use in elastomer compositions as new ingredients. Increasing the carbonization temperature in an inert environment led to an increase in the amorphous carbon content, surface porosity, and pH of the studied materials. Another parameter that showed a tendency to increase with increasing temperature in an inert environment was the BET specific surface area. In the case of using an oxidizing environment, the highest pH value was observed, and the formation of crystalline mineral phases was also observed. The differences in the phase states of the studied materials may play an important role in shaping the spatial stack of the polymer matrix when used in rubber compound formulations.<\/jats:p>","DOI":"10.3390\/polym18161967","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T14:45:06Z","timestamp":1786545906000},"page":"1967","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Influence of Technical Parameters of Carbonization on the Physical and Chemical Characteristics of Materials Obtained by Carbonization of Sunflower Husks from the East Kazakhstan Region"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-3982-2805","authenticated-orcid":false,"given":"Aigerim","family":"Kaiaidarova","sequence":"first","affiliation":[{"name":"Center of Physical-Chemical Methods of Research and Analysis, Farabi University, Almaty 050040, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeryia","family":"Bobrova","sequence":"additional","affiliation":[{"name":"Department of Polymer Composite Materials, Faculty of Technology of Organic Substances, Belarusian State Technological University, 220006 Minsk, Belarus"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrei","family":"Kasperovich","sequence":"additional","affiliation":[{"name":"Department of Polymer Composite Materials, Faculty of Technology of Organic Substances, Belarusian State Technological University, 220006 Minsk, Belarus"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1737-9825","authenticated-orcid":false,"given":"Sergey","family":"Lezhnev","sequence":"additional","affiliation":[{"name":"Graduate School of Metallurgy and Mining Engineering, Rudny Industrial University, Rudny 111500, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6830-0630","authenticated-orcid":false,"given":"Evgeniy","family":"Panin","sequence":"additional","affiliation":[{"name":"Department of Metallurgy and Material Science, Karaganda Industrial University, Temirtau 101400, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7463-1679","authenticated-orcid":false,"given":"Sergey","family":"Nechipurenko","sequence":"additional","affiliation":[{"name":"Center of Physical-Chemical Methods of Research and Analysis, Farabi University, Almaty 050040, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3542-4140","authenticated-orcid":false,"given":"Sergey","family":"Efremov","sequence":"additional","affiliation":[{"name":"Center of Physical-Chemical Methods of Research and Analysis, Farabi University, Almaty 050040, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Manchanda, S., Chandra, A., Bandopadhyay, S., Deb, P.K., and Tekade, R.K.
