Dimas Dwi P Nugroho is presenting on fibers and wood supply. He discusses natural fiber sources including plants, animals, and inorganic materials. Plant fibers come from wood, non-wood, and grass sources. Wood supply can come from mixed tropical hardwood harvested from natural forests or from wood plantations which require higher investment but provide more sustainable and higher quality wood. The presentation covers fiber structure, types of wood and wood densities, and the logging, loading, and unloading process.
