Conversion of waste into innovative materials that contribute to the sustainable development of infrastructure and the construction industry is an important task in today's society. Wood-cement composites which are building materials that combine wood components and a cement matrix are studied herein. These composites have a number of such advantages as high strength, excellent thermal insulation properties, durability and environmental friendliness. The manufactured composite material is a lightweight concrete based on secondary resources, binders and mineral components. Standardized measuring equipment and methods intended to analyze the chemical composition and physical and chemical properties of wood-cement composites (arbolite) were used in laboratory experimental tests. All samples studied were 40 mm × 40 mm × 160 mm lightweight concrete. Four options to obtain a wood-cement composite in various combinations of binders, minerals and other additives were proposed in the research work. All samples were tested to determine the physical and mechanical characteristics and the optimal composition with improved properties. Secondary resources in the form of wood waste and ash from combined heat and power plants (CHPP) were obtained from industrial structures of the Republic of Kazakhstan. An X-ray diffraction analysis of the CHPP ash was performed to determine the chemical mineral composition that showed a high content of silicon. According to the test results, the CH-4 sample demonstrated high physical and mechanical characteristics. The compression strength of the wood-cement composite sample reached 37.1 MPa, and the bending strength was 7.4 MPa on the 28th day, which proves the high performance properties of this composite.

The growing accumulation of plastic waste is a serious environmental problem, and converting this waste into useful materials is an attractive solution. In this work, waste polypropylene (PP) was converted into hard carbon anode materials for lithium-ion batteries. When heated, PP decomposes into volatile hydrocarbons and leaves almost no solid residue, so it cannot be carbonized on its own. The waste PP was therefore first treated with concentrated sulfuric acid, which cross-links the polymer chains into a rigid, infusible network. This suppresses volatilization and promotes the formation of a thermally stable carbonaceous residue. The cross-linked material was then carbonized under argon at 700, 800, 900 and 1000 °C, and 22 to 24% of the original PP mass was recovered as carbon powder, depending on the carbonization temperature. X-ray photoelectron spectroscopy showed that the carbon surfaces retain 6.3–7.5 at% oxygen but almost no sulfur (≤0.2 at%), so sulfur is essentially absent from the final carbons. The carbonization temperature influenced the structure of the carbon and its performance in a battery. Among all samples, PP-900 delivered the highest reversible capacity at 0.1 A g−1, reaching 373.1 mAh g−1 at the 100th cycle. The first-cycle Coulombic efficiency was low for all samples (30–47%) and represents the main limitation of these materials. These results show that acid cross-linking followed by carbonization is a feasible route for converting PP waste into carbon anode material, and identify the low first-cycle efficiency and the rate performance at high current density as the principal issues to be addressed in further work.

Статья посвящена разработке и производству арболита - легкого крупнопористого бетона на основе органического древесного наполнителя и минерального вяжущего. В статье рассмотрены этапы подготовки производства, технологический процесс производства и особенности применения арболита в строительстве. В статье акцентируется внимание на преимуществах арболита, таких как высокая тепло- и звукоизоляция, огнестойкость, биостойкость и прочность, что делает его перспективным шагом для малоэтажного строительства и использования в зонах с высокой пожарной опасностью. Одним из важных аспектов исследования является использование золы теплоэлектростанций (ТЭЦ) в качестве минеральной добавки, что позволяет снизить себестоимость производства и решить проблему утилизации промышленных отходов. Экспериментальные данные о том, что арболитовые блоки, изготовленные с добавлением зол, обеспечивают получение физико-механических характеристик, соответствующих строи. Исследования также затрагивают вопросы безопасности производства, включая переработку древесных отходов и использование нетоксичных компонентов. Технология производства арболита, описанная в статье, проста и эффективна, что делает ее перспективной для широких разработок в строительной отрасли Казахстана. Результаты работы показывают актуальность использования арболита в условиях изменчивого климата и высоких требований к теплоизоляции

ABS plastic waste is upcycled into nanostructured carbon anode through H 2 SO 4 -assisted crosslinking, increasing carbon yield by nearly sixfold. The resulting anode delivers ∼350 mAh g −1 after 100 cycles and exhibits stable low-temperature performance.

В Казахстане тема переработки хлопковых отходов очень актуальна в современных условиях. Учитывая, что Казахстан является одним из крупнейших производителей хлопка в мире, на повестке дня стоит вопрос утилизации большого количества стеблей хлопчатника и других отходов, образующихся после сбора хлопка. Неэффективная утилизация этих отходов приводит к серьезным экологическим проблемам, таким как загрязнение почвы и воды, а также выбросы парниковых газов при их сжигании. Кроме того, отсутствие эффективных методов переработки лишает страну возможности использовать хлопковые отходы для производства ценной продукции, такой как целлюлоза, ограничивая экономический потенциал региона. Таким образом, разработка и внедрение новых эффективных технологий переработки хлопковых отходов в Казахстане имеет не только экологически и экономически актуальное, но и стратегическое значение для устойчивого развития страны. Переработка стеблей хлопчатника и других отходов в лигноцеллюлозу и целлюлозу может стать источником новых экономических возможностей как для мира, так и для Казахстана, где интенсивно выращивается хлопок. Переработка стеблей хлопка и других хлопковых остатков помогает сократить количество отходов, которые обычно выбрасываются в мусор или массово сжигаются после сбора хлопка. Решением этих проблем может стать переработка этих отходов и получение из них ценной продукции во избежание глобального потепления и других негативных последствий, угрожающих окружающей среде.

In Kazakhstan, the issue of providing the population with quality drinking water remains one of the topical and important issues. Despite significant efforts in the field of infrastructure and water treatment technologies, many regions of Kazakhstan still face problems of pollution and insufficient water resources. In this regard, the development of effective water treatment methods is of particular importance. This study considers the issue of wastewater treatment by the combined method of forward and reverse osmosis, which is a key direction in modern water treatment. The relevance of the work is the use of integration of forward osmosis methods with the process of adsorption by powdered activated carbon in wastewater treatment. The use of powdered activated carbon in the process of wastewater treatment leads to a reduction in the content of organic matter, which are water pollutants. As a result of the experiment with pretreatment of wastewater with powdered activated carbon, a decrease in the level of chemical oxygen demand (COD) in wastewater from 538 mg O/dm3 to 256 mg O/dm3 was observed, as well as a relative decrease in the concentration of other indicators. The draw solution in the form of 1.5 M NaCl gradually drawing water molecules from the feed solution pretreated with activated carbon on the tenth day had a concentration of 0.425 M absorbing 2.529 liters of water entering through the membrane that is 27.6% more than the control version of the experiment. The effectiveness of integrated methods lies in the successful combination of different technologies to improve water treatment processes and ensure the availability of clean water not only in Kazakhstan, but also in different parts of the world.
