Environment-friendly composite material formulation

The present invention provides an environment-friendly composite material formulation, which contains: a natural plant powder as main raw material having a weight ratio in the range of 55wt%~65wt% and fortified with a thermoplastic plastic material having a weight ratio in the range of 25wt%~35wt%; and a natural adhesive having a weight ratio in the range of 5wt%~15wt%. The composite material is produced by selecting a natural plant powder as the main raw material which is fortified with a thermoplastic plastic material to increase the strength, and mixing an adhesive which is made from natural plants. Since environmental protection is a high priority the weight ratio of the natural plant powder and the natural adhesive is high, the premolding articles made of the composite material by a molding machine are environmentally friendly with an improved strength. Furthermore, since the thermoplastic plastic material is easy to be decomposed, the nontoxic and decomposable premolding articles after being used can be
