Summary: This study aimed to produce an environmentally friendly, easily accessible, inexpensive and renewable construction composite material with thermal and water insulation properties. Waste papers, hazelnut shells, pinecones and sheep wool were used in the production process. The filling rates of the materials were optimized using the RSM. A hydrophobic surface-active substance was applied to reduce water absorption, microbial activity and mold formation. The specimens exhibited contact angles of 84 to 146 degrees, thermal conductivity of 0.0511 to 0.0861 W/mK, and densities of 0.678 to 0.99 g/cm3. Compressive and flexural strength tests showed high compressive strength, with the highest value of 32.8093 N/mm2 in specimen N25, and the highest flexural strength of 6.352 N/mm2 in specimen N20. A completely environmentally friendly, biodegradable and low-cost material was successfully produced from biomass waste.

Summary: This study investigates the influence of raw material compositions and various sintering temperatures on the synthesis mechanism and reaction path of cordierite. The results suggest that forsterite and magnesia-alumina spinel are firstly generated in the low-temperature section while using pure single oxide materials. Then, they combine with Al2O3 and SiO2 to form cordierite. The addition of CaO and TiO2 promotes the formation of cordierite phase.

Summary: This study quantifies the potential CO2-eq. emissions reductions in cement production in Europe until 2050 by employing measures such as clinker substitution, alternative fuels, kiln improvements, and carbon capture and storage. The results show that significant reductions in CO2-eq. emissions can be achieved by 2050 through these measures, with additional reductions possible through decarbonisation scenarios for the electricity mix. Multiple pathways exist for the cement sector to achieve and surpass global climate targets.
