Abstract
Plastic waste is shredded and formed to a desired shape and held together using a binder and/or heat, etc. The resulting composite material may be useful for building and/or furniture and/or flooring, etc. (similar to wood composite board). In some embodiments, the board is highly water resistant. Optionally, the board is made of layers. For example, an inner layer has reduced density and/or an outer layer may have decreased particle size and/or increased fiber content.
