Recycling of Wood – Plastic Composite Prepared from Poly (Ethylene Terephthalate) and Wood Sawdust

Abstract

 Effects of alkyls treatment of Sawdust on the mechanical and physical properties of wood-plastic composites are investigated.  Effects of depolymerized polyethylene terephthalate (DPET) and VV/55 on the properties of composite.  50% of the produced blends in wood-plastic composites are used for waste recycling and environmental protection.Plastic waste has become one of the humanities and the ecosystem balance serious environmental Challenges. Furthermore, it is the primary source of plastic pollution because it is inexpensive, widely available, and frequently discarded. Using various waste materials and side fractions as part of woodplastic composites is one way to promote the circular economy (WPC). Several environmental benefits can be realized by using recycled plastic, including extending the usable life of plastic, reducing waste, contributing to the development of trash recycling, and preventing resource depletion. One of the most efficient recycling processes is glycolysis; the (PET) is depolymerized by ethylene glycol in continuous stirring reactors at temperatures between 200 and 220•C using glycol as solvent. This work concentrates on the experimental investigation of composite materials from DE polymerization PET, Unsaturated polyester, and VV/55 as a matrix and wood sawdust as reinforcement. The composite samples were checked by the Hardness test, water test, and density test. According to the experimental results, the optimum value is at (2%) wood percentage, giving high hardness value, low density, and low water absorption.

Development of Wood Polymer Composites from Recycled Wood and Plastic Waste: Thermal and Mechanical Properties

“…The specimens were initially weighed and immersed in water at ambient conditions. The samples were weighed at regular intervals (2,4,6,8,10,12,14,16,18, and 20 days). The percentage of absorbed water (W) in the composite was calculated according to Equation (1):…”

“…Wood is a renewable and low-carbon material [2,3]. It has been widely used in different interior and exterior applications [4,5], such as decking materials [6], fencing [7], landscaping timbers [8], furniture, and automobile products [9]. However, the main drawbacks of wood are their liability to distort with the absorption of moisture and their vulnerability to degradation by microorganisms [10,11].…”

Physicomechanical Properties of Sustainable Wood Plastic Composites of Tropical Sawdust and Thermoplastic Waste for Possible Utilization in the Wood Industry

“…The determination of the hardness properties of composites [16] was carried out at room temperature using the CV instruments Shore D hardness tester apparatus in accordance with [17]. The applied load was equal to the 50 N and the depressing time of measuring was equal to the 5 s.…”
