In this study, it was aimed to utilize the wastes of wheat straw, goose down and wood industry and bring them into the economy. A sustainable insulation material was produced using environmentally friendly water-based PVA styrene acrylic copolymer as a binder with these wastes. In the study, mechanical properties, acoustic absorption and burning resistance were examined. Response Surface Method Box-Behnken Design (RSM-BBD) was used for experimental design and optimization. As a result of mechanical tests, it was seen that the binder ratio had a very high effect on mechanical strength. It was observed that the acoustic absorption coefficient increases with the increase of each of wheat straw, wood shaving, goose down and water-based copolymer resin. Styrene acrylic copolymer was found to be suitable binder for agricultural wastes. AL 2 O 3 , MgO, and Zn[B 3 O 4 (OH) 3 ] were used to increase fire resistance. The results revealed that these compounds can be used as fire retardants for materials consisting of cellulosic-based fillers and water-based polymer binders. The best combustion results for the material were achieved with Zn[B3O4(OH)3]. Flame retardants reduced cellulosyl and polymeric mass loss by up to 61.5 %. It was observed that the best fire resistance was F27 sample, which started to extinguish after two minutes despite the continuation of the fire and extinguished immediately after the fire was removed. The study revealed that such materials can rival conventional materials for green credentials, technical, economic, and environmental aspects. • Styrene acrylic copolymer was found to be suitable binder for agricultural wastes. • Flame retardants reduced cellulosyl and polymeric mass loss by up to 61.5 %. • The best combustion results for the material were achieved with Zn[B 3 O 4 (OH) 3 ]. • Al 2 O 3 , MgO and Zn[B 3 O 4 (OH) 3 ] were suitable fire retardants for sample materials. • Wheat straw, sawdust, goose down and polymer had a good effect on sound insulation.

This study presents an alternative process that produces drinking water from seawater, which can solve the increasing drinking water shortage. The aim of this study is to produce drinking water from original Black Sea water with three-compartments unit bipolar membrane electrodialysis. In the experiment's operation parameters, the effects of flow rate, potential, and temperature of drinking water, hydrochloric acid, and sodium hydroxide production were investigated. Response surface method Box-Behnkem design was applied for modeling and optimization. The optimum operating conditions were determined as a temperature of 35 °C, a flow rate of 0.5 l/min, and a potential of 12.5877 V. Under these conditions, the highest removal efficiency was found at 98% in Na+, 97% in Cl−, Ca +2 77%, Mg+2 85%, and K+ 59% ions. The microbiological content was cleaned in 15 min without any additional processing. As a result, drinking water production in compliance with the 'Regulation on Water for Human Consumption/Turkey' was achieved. The results obtained are promising for the production of drinking water from cold sea waters with low salinity such as the Black Sea and the production of drinking water from low salinity, cold sea waters with bipolar membrane processes. It can reduce energy consumption by incorporating alternative energy sources such as seawater wave energy into the process.

[Display omitted] • A hydrophobic building material was produced as an alternative to natural wood. • Heat transfer coefficient reduced with various combinations. • A material with high compressive strength was obtained. • The material environmentally friendly is produced from biomass waste. This study aimed to produce a construction composite material that is environmentally friendly, easily accessible, inexpensive and renewable and provides thermal and water insulation. Waste papers, hazelnut shells, pinecones and sheep wool were used at the production stage. The filling rates of the materials were optimized using the RSM. A hydrophobic surface-active substance was used to reduce water absorbability, microbial activity and mold formation. It was observed that these specimens' contact angles were 84° to 146°, thermal conductivity were 0.0511 to 0.0861 W/mK and densities were 0.678 to 0.99 g/cm3. As a result of the compressive and flexural strength tests, it was found that the compressive strength of the specimens was very high, the highest compressive strength was found as 32.8093 N/mm2 in the specimen N25, and the highest flexure strength was found as 6.352 N/mm2 in the specimen N20. A completely environment-friendly, biodegradable and low-cost material was produced out of biomass wastes. [ABSTRACT FROM AUTHOR]

• Hisrophobic clay material was rendered well hydrophilic. • A very strong material was obtained using natural fibers. • Heat transfer coefficient reduced with the addition of natural fiber. • A material with very low water absorption was produced. The purpose of this study was to produce nature-friendly insulating materials designed from natural substances in the world where energy and environment conservation has been increasingly coming to prominence. In the samples of the produced insulating material, wool, kenaf and wheat straw were used as fiber, clay was used as the filling material, and water-based paint binder was used as the binder. The particle size and the ratio of clay and the kind of fiber were determined as the parameters of production. The thermal conductivity coefficient, water repellency, compression stress and force resistance were measured for all samples. The material coded as N2 was selected as the best material based on density (0.45 g/cm3), thermal conductivity coefficient (0.061 W/mK), compressive strength (4.9 MPa/m2), force resistance (9200 kg force/m2), water absorption (% 0,0015 /hour) and contact angle (150,72°) in comparison to the other produced materials. A material, which is completely biodegradable, without toxic gas emission and nature-friendly, was produced. [ABSTRACT FROM AUTHOR]
