Abstract
A method is disclosed for producing a wood-thermoplastic composite material using a high bulk density feedstock. The feedstock is formed by feeding a wood-thermoplastic mixture to a pellet mill where the bulk density thereof is increased by a significant amount. The pelletized feedstock may be stored for later formation into a finished product and may be blended as necessary to maintain product quality. The feedstock is easy to handle and transport and provides a manufacturer with a large degree of flexibility and control over the manufacturing process.
