Utilization of waste plastic and wood in the composites industry

Some industries in the world are always looking for technologies to produce composite materials based on wood and polymers. Based on the European Union environmental legislation, replacing 80% of car body parts and interior trim, window and door profiles, flooring buildings, and wooden home appliances with this type of composites is targeted by 2025. The importance of lignocellulosic materials is high enough that the material is regarded as reinforced plastics by many researchers. The use of plastic and wood waste in the world is something worthwhile receiving high attention by researchers for various reasons including affordability, sustainability, added value, and reducing energy. Types of waste polymers including polypropylene (PP) and high density polyethylene (HDPE) have a very high production volume. In addition, polyethylene terephtalate (PET), polystyrene (PS) and polyethylene (LDPE) are also of considerable production volume. Types of thermoplastics produced in various forms can be recycled after use. Research in this field has shown that wood and cellulosic waste with plastic waste could be used in the manufacture of wood-plastic composites.
