Abstract
A thermoplastic starch composition acquired from compounding a mixture comprising starch-containing agricultural byproducts in 45 to 70% by weight of total composition, the agricultural byproducts having a starch content less than 50% 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; the compounding performed at a first temperature which is higher than room temperature.

1-25. (canceled)
A method for forming a bio-resin, said 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;
- and
- compounding the first blend and the second blend to form a bio-resin.
A thermoplastic composition formed from starch-containing agricultural byproducts, comprising:
- a heat-compounded mixture of:
- 45% to 70% by weight of palm oil fruit bunch waste, the palm oil fruit bunch waste having a dry weight starch content of less than 50%;
- 25% to 50% by weight of polypropylene;
- 0.01% to 5% by weight of an organic peroxide initiator;
- and
- at least 1% by weight of a maleic anhydride modified polyolefin coupling agent.
