THERMOPLASTIC STARCH COMPOSITION DERIVES FROM AGRICULTURAL WASTE

The present invention provides a thermoplastic starch composition， comprising: starch-containing agricultural waste containing less than 50% (dry) starch content of 45% to 70% by weight of the total composition; 25 to 50 weight percent thermoplastic synthetic polymer in the total composition; 1 to 10 weight percent plasticizer in the total composition; And from 1% to 5% by weight of the coupling agent in the total composition; The blending relates to a composition carried out at a first temperature above room temperature. 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.
