“…5 In addition, the EPS foam has a short service life and it mostly ends up in either incineration or landfill. 4,6 Recycling rate of EPS foam is very low and expensive. Thus, most EPS foam wastes are sent to landfill and they contribute to environmental pollution, as they are non-biodegradable plastics.…”

Recently, many agricultural waste were left for open burning or as landfill in many agricultural land, for example, coconut shells. Besides, expanded polystyrene (EPS) foam is one of the most used plastic products which mostly ends up in landfilling as many of its products were made for one-time use only. In order to reduce these wastes, this project focuses on the preparation of a new material that is coconut shell powder (CSP)-filled EPS wood plastic composite (WPC). This research investigates the effects of CSP content and alkaline treatment with sodium hydroxide (NaOH) on mechanical and water absorption properties of EPS/CSP WPCs. The mechanical properties, such as tensile strength, Young’s modulus and flexural modulus, increased as the CSP content increased. However, elongation at break and flexural strength decreased with CSP content. Moreover, water absorption of EPS/CSP WPCs showed an increasing trend with CSP content. After alkali treatment, the mechanical properties of EPS/CSP WPCs were enhanced, but the water absorption properties of treated EPS/CSP WPCs were reduced due to the reduction of the –OH groups of CSP. Fourier transform infrared analysis was carried out to measure the functional groups of untreated and treated CSP. The fracture surface of CSP, untreated and treated EPS/CSP WPCs were examined by scanning electron microscopy.

Lignosulfonate is a cheap material available in large quantities obtained as a byproduct of paper and cellulose. In this work, blends of polypropylene (PP) and sodium lignosulfonate (LGNa) were developed to evaluate the potential use of lignosulfonate as a lightweight, thermal insulation and flame retardant material. The blends were obtained by mixing in a torque rheometer and molded after compression. The blend proprieties were evaluated by physical, morphological, thermal, thermal conductivity, and flammability tests. The measured values were compared with theoretical models. The results indicated that a heterogeneous blend with a higher number of separated domains is formed when the LGNa content increases from 10 to 40 wt%. In addition, the density and thermal conductivity coefficient of the blends studied are not affected by the addition of LGNa. However, when the LGNa content in the blend exceeds 20 wt% the thermal stability and flame retardant proprieties are considerably reduced. The theoretical models based on the rule of mixtures showed a good agreement with the experimental values obtained from blend density, thermal conductivity, and thermal stability. In general, lignosulfonate tested in this work shows potential to be used as a reactive component in polymer blends.

In this study, wood plastic nanocomposites (WPNC) reinforced with nano magnesium oxide (MgO) were produced in a flat press using the dry blending method. It is aimed to investigate the technological properties of the produced WPNC panels. To achieve this aim, scots pine wood flour, waste polypropylene (PP), maleic anhydride grafted PP (MAPP) and nano MgO were mixed and combined in eight different formulations by dry blending method. The densities, water absorption and thickness swelling, tensile strength, bending strength, modulus of elasticity (MOE), surface roughness and Shore D hardness properties of the obtained WPNC panels were determined. On the other hand, scanning electron microscope (SEM) micrographs were obtained to determine the morphological properties of WPNCs. Nano MgO and MAPP reinforcement positively affected the technological properties of flat-pressed WPNC panels. It was determined that increasing nano MgO ratio and MAPP reinforcement increased the water resistance of WPNC panels. It has been determined that the use of MAPP and nano MgO significantly improves the mechanical properties of WPNC panels. When the SEM micrographs of WPNC panels were examined, it was observed that large voids were formed especially in WPNC panels that without MAPP and nano MgO, and these voids were largely eliminated with the increase of MAPP reinforcement and nano MgO ratio. Following the technological results obtained within the scope of this study, it is recommended to conduct new studies to investigate the biological resistance of nano MgO reinforced WPNCs due to the known antibacterial, catalytic and photocatalytic properties of nano MgO.
