“…Hazelnut shells based composites were prepared by using thermoplastics such as PP, [14][15][16][17][18] polyethylene, 16,19 polylactic acid (PLA), 2,[20][21][22] polymethylmethacrylate, 23 and thermosets including epoxy, 2,[20][21][22] urea formaldehyde, 24 polyester. [25][26][27] In addition to these, HNS filled polyurethane (PU) rigid foams 28 were also reported in the literature. Also, HNS was mixed with various fillers and hybrid filler-loaded composites were also reported in the literature.…”

In this study, waste hazelnut shells (HNS) were powderized and used as the filler for the fabrication of sustainable polymeric composites. HNS based composites can be used for many applications because of their tunable intrinsic brown color for various indoor and outdoor applications including decking applications and furniture that require a natural esthetic appearance. Polypropylene (PP), styrene-b-(ethylene-co-butylene)-b-styrene (SEBS), and 50/50 PP/SEBS blends were used as the polymeric matrixes. HNS concentration was set to 2.5, 5, and 10 wt%. PP/SEBS blend and HNS filled granules were prepared by melt mixing in an extruder. Following that polymeric films were fabricated from the granules by compression molding. The morphological, structural, thermal, mechanical, contact angle, water absorption analyses were performed in order to characterize the composites. Matrix type and filler concentration were found significant for the properties. PP/SEBS blends showed homogeneous morphology. At low concentrations, fillers were well-dispersed. On the other hand, at 10 wt% HNS loading agglomerations were observed and mechanical properties showed a noticeable drop. PP-based composites showed the highest tensile strength and elastic modulus with the lowest tensile strain. SEBS-based composites showed the lowest tensile strength and elastic modulus with the highest tensile strain. PP/SEBS composites showed mechanical properties between PP and SEBS. The incorporation of SEBS into PP increased the flexibility of the composites and resulted in relatively higher strain at break.

“…HFM works by measuring, recording, and printing using this equation and calibrated software. Before starting experiments, the instrument was calibrated with pyrex-7740, whose thermal conductivity is known for certain temperatures, and with a Pyrex calibration file [19]. The reproducibility of the device was reported as ±2% [20].…”

Industrial symbiosis is one of the key approaches to meet sustainable and low carbon production targets. Thus, through circular approaches, it is possible to reduce the use of natural crude materials and make production processes waste-free in the metallurgical industry. The purpose of this study was to study the possibility of using various metallurgical waste and low-grade semi-finished products, which do not have a direct application area, in the production of heat-resistant carbon-containing refractory bricks through the combustion synthesis (CS) method. In the experiments, used metallurgical wastes were wet filter cake (FC), sludge (S), and refractory magnesite scrap (MS) while semi-products were rich and poor dust of chrome spinel (Cr-S). Simultaneously with the experiments, thermochemical simulation studies were carried out using the HSC Chemistry 6.12 to predict the thermodynamic properties of the reactions and possible reaction products. Thermal conductivity coefficients were determined in products in terms of thermal properties of composite samples, they were between 0.511 and 1.020 Wm/K. The phase compositions of the produced samples were determined via XRD technique. The TG-DTA technique was used to characterize thermal behavior of products. In addition, mechanical properties were determined by compression strength test. As a result of experiments, it was observed that Cr-S-rich-based samples showed a promising result in comparison to others: increasing amount of useful carbide phases were formed and demonstrated a high value of mechanical properties. Compression strength was increased from 2.7 MPa (sample №4) to 15.8 MPa (sample №1) with increasing chromite-containing phases in the green samples.
