Abstract

Recycling of construction and demolition waste (CDW) which contains
materials with high resource value such as plastics, metals, wood, glass
and concrete has been investigated in recent years due to tightening
environmental legislation. Wood-plastic composites as an environmentally
friendly material provide a possibility to enhance the recycling of
material. The effect of the addition of CDW on the mechanical and
moisture properties of WPC is studied in this paper. Three types of
wood-plastic composites were manufactured with different amounts and
composition of a CDW filler. Their properties were compared to the
reference composite manufactured with virgin wood fibers and polypropylene
as the polymer. It was found that the addition of the CDW filler
weakened the mechanical properties of the composite generally, except
for the fact that the Charpy impact strength was improved significantly.
Minor variations in the composition of the CDW filler did not have an
impact on the mechanical properties, but an increase in the amount of
filler increased the deterioration of mechanical properties. For
moisture properties, the addition of the CDW filler decreased the water
absorption and thickness swelling of the composites. An increase in the
filler content improved the thickness swelling more significantly than
water absorption.
