“…Mixing ratios of the powders were not fixed; sawdust and dust from pine, beech, poplar, MDF, chipboard, wood scraps, and some edge bands were collected. After this waste material was dried in the oven, it was ground and sieved through a sieve with a thickness of 200-mesh and a powder material was produced in the form of flour (Horta et al 2017). When the values of the substances in this mixture were analyzed, the abundance of cellulose material were seen.…”

Many engineering designs focus on the production of durable, ergonomic, and economical new materials. In today’s world where natural resources are rapidly decreasing, recycling waste materials is of great importance. As a result of the bending test, the sample’s return to its original dimensions shows the plastic feature of the material. It was observed that the tensile strength can be increased if the speed of the injection machine is well adjusted in the production of tensile strength testing samples. There was an increase in the screw tensile strength of the samples and the joint hardness strength. Thermogravimetric analysis (TGA) showed that the reference samples were completely crumbled around 480 °C, and it was observed that only quartz remained from the input materials. Differential scanning calorimetry (DSC) showed that the peak point in the reference sample was at the heat flow rate of 29 m/W, while it was 18 to 19 m/W in the doped groups. Melting temperature was observed in the range of 125 to 135 °C in all groups. The mechanical properties of the quartz-substituted samples increased compared to the reference sample. It was observed that the quartz and wood powder contained in the mixture worked in harmony.

In this article, the effect of carbon nanotube’s (CNT) surface modification on mechanical, thermal, and morphological properties of nanocomposite with different content of CNTs was studied. CNT/high-density polyethylene (HDPE) nanocomposites were prepared by a mini twin-screw extruder. To modify the dispersion of MWCNTs in HDPE, the surface of CNTs was functionalized by HNO3 and stearic acid (SA). The tensile tests results show that addition of 5% of acid-treated CNT in HDPE cause to increase in Young’s modulus and yield strength up to 4% and 6%, respectively; as compared to unmodified CNT/HDPE nanocomposite. The presence of the SA on CNTs can lead to slight decrease of the CNT-SA/HDPE strength properties; when compared to pure CNT/PE nanocomposite. However, there is a fracture toughness enhancement in CNT-SA/HDPE up to 10% compare to unmodified CNT/PE nanocomposite. Furthermore, the calculation of the stress whitening zone of all samples verifies the fracture toughness data of CNT/HDPE nanocomposites. Scanning electron microscopic images showed that the best dispersion of CNTs in the HDPE matrix was seen in CNT-SA/HDPE nanocomposite.

“…Sawdust can have different reuse applications; calcareous sawdust from marble processing plants can replace expensive additives in the building sector [63] whereas wood sawdust can be used to produce wood-plastic composites [64] and, in wastewater treatment facilities, for the removal of heavy metals such as nickel from aqueous solutions [65]. A furniture industry in Zimbabwe is using wood sawdust to produce briquettes that cover part of its fuel requirements [66].…”

Industrial Symbiosis in the Balkan-Mediterranean Region: The Case of Solid Waste

et al. 2022

View full text Add to dashboard Cite

The treatment of waste and especially solid waste, the type with the highest increase in terms of annual generation over the last decade, is a key issue in the Balkan and Mediterranean region. Piecemeal efforts to deal with it within the prevailing linear economy model were not successful since the techniques used such as recycling and reusing could not be effective with the existing products. A definitive solution requires the switch to a new model, the circular economy model, which will facilitate the tackling of the excessive use of virgin raw materials and waste generation. The design and development of a digital solid waste reuse platform in the context of the EU-funded Interreg Project SWAN involving four countries: Albania, Bulgaria, Cyprus and Greece, was a step in this direction. The present paper based on the evidence drawn from this project examines the current situation and the future trends in the solid waste reuse and industrial symbiosis schemes in this region.
