Abstract
A thermoplastic starch composition acquired from compounding a mixture comprises starch-containing agricultural waste in 45 to 70% by weight of total composition that the agricultural waste contains starch content less than 50% in dry weight; thermoplastic synthetic polymer in 25 to 50% by weight of total composition; plasticizer in 1 to 10% by weight of total composition; and coupling agent in 1 to 5% by weight of total composition; wherein the compounding is performed at a first temperature which is higher than room temperature.
Claims15
A method of forming a bio-resin product, the method comprising:
- forming a first blend by combining an agricultural byproduct having a starch content of less than 50% by dry weight and a plasticizer;
- forming a second blend by combining a synthetic polymer and a coupling agent;
- compounding the first blend and the second blend, the compounding including combining the first blend and second blend in an extruder and coextruding the combined first blend and second blend to form a bio-resin;
- and
- forming a product from the bio-resin.
