As the problems associated with sustaining and enhancing the world's forest and agricultural resources compete with the needs of a rapidly increasing and affluent population, the management of our land becomes a much more complex and important issue. One of the most important environmental features of wood and other woody-like fibers is that they are renewable and can be sustainably managed. Composite wood and natural biofiber products are beneficial to humans and to the environment in that they serve as environmentally effective alternatives to other non-renewable and/or non- or less-recyclable mineral- or petrochemical-based materials.
