Fig. 1 shows the flexural strength and the flexural modulus of the WPC freshfeed, WPC scrap and their mixtures. The flexural strength and flexural modulus of the WPC profiles extruded from 20 to 30 wt.% of scrap mixed with 80 and 70 wt.% of WPC freshfeed were very close to that of the WPC extruded from freshfeed only. A significant drop, by 23% in the flexural strength and by 29% in the flexural modulus, to the level close to those of the pure scrap was apparent when 40 wt.% of scrap was mixed. Further increments of the WPC scrap to 60 and 80 wt.% in the mixture evidently reduced the flexural strength and the flexural modulus. Hence, the mix ratio of the WPC scrap:freshfeed at 30:70 was most appropriate ratio in terms of flexural properties and reduction of cost of WPC freshfeed for recycling WPC.
