Abstract
A composition of matter comprising at least 2% by weight of a fibrous material and at least 30% by weight of a binding material such that the composition can be melt-molded into articles which have mechanical strength sufficient for their intended uses and which are biodegradable. The binding material is formed of natural substance and may also include up to 30% by weight synthetic, water-soluble polymer. The fibrous material may be cellulose and/or mineral fibers which provide the attributes of reinforcement and degradability. The composition may further include up to 20% by weight liquid or solid plasticizer which serves to lower melt viscosity and add toughness to the composite material.
