Summary: This study proposed a rapid disposal platform for waste textiles, converting them into value-added products. Catalytic pyrolysis of WT can convert over 80 wt% of WT into syngas and CH4, with CO2 as a raw material to increase the production of CO. This process offers an effective means to minimize the formations of harmful chemical species.

Summary: Glycerol, a co-product in the biodiesel process, can be used as a raw material in a biorefinery scheme. Studies have been conducted to selectively reduce and oxidize glycerol, as well as steam reform it, to produce valuable chemicals and energetic compounds. The integration of these processes into a biorefinery framework has been demonstrated. The conversion of glycerol to various compounds such as propylene glycol, ethylene glycol, hydrogen, dihydroxyacetone, lactic acid, syngas, carbon dioxide, and methane shows the potential of utilizing glycerol in expanding biorefinery schemes.

Summary: Zrx/(Fe-Ce) catalyst was prepared by co-precipitation method to catalyze CO2 and ethanol for the production of diethyl carbonate (DEC). The introduction of Zr significantly improved the acid-base active sites and oxygen vacancies on the catalyst surface, resulting in higher activity and selectivity. Under optimized conditions, a high DEC selectivity of 96.7% was achieved using Zr0.1/(Fe-Ce) catalyst. Using fermentation tail gas as CO2 source, 56.0% selectivity of DEC was obtained. This study provides a new idea for the utilization of CO2 fermentation gas and the development of cleaner fuel production process.

Summary: This study evaluated the suitability of agricultural lignocellulosic biomass (vine pruning waste) for particleboard production and found that the waste content affected the thickness and strength properties of the boards. Boards with 50% waste content met the minimum strength requirements. Pruning waste also reduced axial forces during drilling and improved swelling and water absorption properties.

Summary: The depletion of oil resources has led to efforts in utilizing biologically available sources to produce polyols for polyurethane foams. Plants and chitosans are renewable sources of oils, sugars, starches, and cellulose, which can be converted into polyols. In this study, a low-molecular-weight chitosan was hydroxyalkylated with glycidol and ethylene carbonate to obtain polyols for rigid polyurethane foams. The properties of these polyols, such as density, viscosity, surface tension, and hydroxyl numbers, were analyzed. The results showed that hydroxyalkylation of chitosan with glycidol in the presence of glycerol produced multifunctional polyols suitable for polyurethane foams with favorable properties.

Summary: This study explores the feasibility of using hemp shives as a partial substitute for traditional wood in the production of particleboards. The results show that particleboards containing hemp shives have lower density, but have minimal effects on strength and modulus of elasticity, and no significant differences in internal bond strength compared to conventional particleboards. Additionally, particleboards with hemp shives exhibit reduced swelling compared to particleboards made entirely of wood particles.

Summary: Poland relies heavily on coal for energy production, and the combustion process generates fly ashes, which account for a significant portion of industrial waste in the country. This paper discusses the amounts and disposal of fly ashes in Poland, highlighting their high recovery rates and their potential as anthropogenic raw materials. The use of recovered fly ashes in the cement industry is exemplified as a successful case of industrial symbiosis, benefiting the economy, environment, and society as a whole. The anthropogenicity index is used to assess the substitutability of primary raw materials with secondary ones in cement plants.

Summary: This study investigated the sequestration of CO2 in municipal solid waste incineration (MSWI) fly ash through mineral carbonation. The mineral carbonation process allowed for the storage of CO2, but also resulted in a decrease in compressive strength of the alkali-activated materials. The study highlights the importance of further research on utilizing high-calcium fly ash (HCFA).

Summary: Sustainable development is the common goal of bioeconomy and circular economy, with biorefinery platforms playing a strategic role in enhancing the bioeconomy. Utilizing renewable sources for fuel, chemicals, and energy production promotes sustainability, reduces greenhouse gas emissions, and creates manufacturing jobs, ultimately advancing regional and social systems. Through the implementation of biorefineries and low environmental impact technologies, new sustainable production strategies for biofuels and energy can be established, making biobased industries more competitive and improving current value chains.
