Pitch pockets ordinarily have so little effect on structural lumber. However, the presence of a large number of pitch pockets may indicate shake or weakness of bond between annual rings.

Another segment for recyclate is the substitution of conventional construction materials such as hardwood, non-structural lumber, or concrete. It is precisely the plastics specific characteristics from which technological advantages can be derived, leading to a low system cost as long as a comparable lifetime can be achieved [251, 267, 268]. 

Based on the properties of glass fiber reinforced PCC, a number of products are being developed. One product is structural lumber. This lumber differs from decking because it is much stiffer and stronger. Therefore, this lumber can be used as the support structure for decks. Figure 13.3 shows the extrusion of a plastic board using glass fiber reinforced nylon 6 PCC.
