Since 2007, the Department of Chemical and Biological Technologies has been established as a structural unit as a result of structural reorganization at the newly created Faculty of Chemical Technology and Metallurgy. The department is headed by Doctor of Chemical Sciences, Professor Nazibrola Kutsiava. Address: room 202, II educational building, phone: 0322 77 11 11 (7369), e-mail: n.kutsiava@gtu.ge
15 professors, 12 associate professors, 2 assistant professors, 2 assistants, 1 academician, guest professor and 1 guest teacher work in the department.
The relevant directions of the department are:
A certain group of the faculty's academic staff members are members of the European Society of Ceramicists (28 countries) and the International Federation of Ceramicists (42 countries). Prof. Z. Kovziridze is a member of the councils of both of these organizations. Over the years, under the auspices of these organizations, the academic staff has participated in international scientific conferences in many cities around the world, and more than 100 scientific presentations have been made in the forums on behalf of the Technical University.
According to the resolution of the Academic Board of the Georgian Technical University on December 27, 2017, the "Institute of Bionanocomposites and Nanocomposites Technology" was established at the Faculty of Chemical Technology and Metallurgy (Director Prof. Z. Kovziridze). A cluster was formed with this institute, which includes 7 agencies: Institute of Physics and Technology; Institute of Clinical Oncology, Kutaisi Oncology Center "Saroveli"; R. Institute of Machine Mechanics of Dvali; A. Llochrelidze Institute of Mineral Raw Materials of the Caucasus; V. Chavchavadze Research Institute of Cybernetics and R. Agladze Institute of Inorganic Chemistry and Electrochemistry.
The new carbide-sialon composites obtained by innovative technology under the leadership of Z. Kovziridze, which are characterized by high fire resistance, smoothness and chemical resistance to thermal shocks, can be successfully used in rocket and space technology, for high-temperature shields, armor, turbine disks and wings, and wear-resistant nodes of nuclear reactors. In 2015-2017, at the University Material Science Center of Bionanoceramics and Nanocomposites, the technology of cement kiln sludge was developed on the basis of local raw materials under the grant of Shota Rustaveli National Science Foundation of Georgia. According to the results of factory tests, it is subject to implementation in the future.
A fundamentally new innovative technology with a high antiblastoma effect was created by Z. Kovziridze for the first time in Sakar-Tvelo; The effect of anti-tumor monotherapy treatment and adjuvant action in the polychemotherapy treatment of cancer were determined. This innovative technological method was called "Cancer therapy". "LEZI-1", a universal and completely harmless device created by Prof. Z. Kovziridze with the method of controlled local hyperthermia, was introduced in the Kutaisi oncology center for the treatment of oncological diseases. 450 patients with third and fourth stage cancer on different organs were treated. According to the obtained results, the presentation on cancer therapy took the first place on October 10-13, 2010 at the first international conference of young scientists held in Tbilisi. A great success was also the presentation of cancer therapy equipment, which won first place at the World Congress in Dresden on August 21-25, 2016, where 47 countries participated.
Mathematical calculation of material consolidation processes was carried out under the authorship of Z. Kovziridze, for which he received the prize of the State Committee of Science and Technology. Out of 6 mathematical formulas created by him, 5 are registered in "Sakpatenti". Three were published in journals with an impact factor of Scientific Research Publishing, the world's largest association of journals. According to feedback from the central office of this association, articles on these formulas are in great demand among scientists, engineers and academic staff. 19 monographs have been published under his authorship, including 5 published abroad.
In the department, researches are carried out and are being carried out in various directions:
Using non-deficient and cheap additives (agricultural liquid waste and secondary products) to increase the octane number of single-grade gasoline and the yield of light fractions included in oil. (Professors T. Shakarashvili, N. Kutsiava and Associate Professor M. Andghuladze);

Synthesis of linear heterochain polymers of alkyne-azide, by the so-called "click reaction" under the leadership of Academician R. Katsarava. As a result of research, the original "One-pot/two-step/three" was developed. -component synthesis) synthesis scheme; The synthetic possibilities of the polycondensation method were significantly expanded. A number of biocompatible biodegradable polymers have been obtained and studied, and innovative biomaterials have been created based on them. The prospects of the biomedical use of polymethrein are great, their commercial potential (many miles) in the market) in the form of surgical materials, drug delivery/carrying systems and therapeutic polymers; Also significant are the results of the research, which are based on obtaining a new generation of biocompatible nanoparticles (NN) based on biodegradable polyesters. The development of the obtained nanoparticle spots in the ocular barriers and the prospect of using them as nanocontainers for the introduction of drugs into the eye have been determined;
The composition of the mirabiliite deposits in the "Sakhare" and "Grdzeli" lakes in the surrounding area of Gareji and the expediency of using the mirabiliite lakes of Azamburi for resort purposes were determined; A complete technology for obtaining 40,000 tons of anhydrous sodium sulfate per year was developed (leader - Prof. M. Mchedlishvili);
Rustavi production union together with "Azoti" specified the technological parameters of cyanic acid production in order to improve the stability of the process and economic indicators; Works were also carried out to clean wastewater with residual coal tailings (supervisor Prof. L. Gvasalia);
According to the technology developed at the Department of Electrochemical Production Technology in the Rustavi Electrolytic Manganese Dioxide Factory, natural manganese dioxide export products were released (Professors: T. Agladze, J. Shengelia, G. Gvelesian);

Cheishvili);
Prof. G. Gaprindashvili's leadership was the first time to synthesize pigments and fluxes of solid structure using local raw materials, which is a unique material for obtaining artistic glazes in church and secular painting, in the technique of enamel partitioning; Also important is his contribution as a scientific consultant in the modern enterprise "Pitcher School-Academy" built in Alaverdi Diocese (Telavi city), where in the near future the production of two- and three-ton ceramic wine pitchers will be carried out using new technology. In addition, the mentioned enterprise ensures the release of secular and church painting paints, artistic products made with bone porcelain partition technique, etc.;

Both bacteria and viruses are the research objects. Studies were conducted on the prospects of the specific virus of Xanthomonas vesica-taria to prevent bacterial spot diseases of tomatoes (Prof. T. Buachidze, Assoc. Prof. N. Butskhri-Kidze, Prof. L. Topuria);
The close and fruitful cooperation established between the direction of biotechnology and Biologica LLC is worthy of special mention. This especially applies to the development and production of training test sets based on various technologies. These are both microbiological and ELISA (enzymatic immunoassay) and chromatographic sets (ion exchange and thin layer chromatography), electrophoresis and gel filtration sets (Prof. E. Kvesitadze).
