In this paper,the main study is the preparation of foamed packaging material using broomcorn straw and adhesive which is made of polyvinyl alcohol、water—soluble amylose and water as raw material.

Ethanol production process by solid fermentation of sweet sorghum stalk was as follows: partial heated sweet sorghum stalks after grinding mixed with the unheated, when the temperature of the stalks reached up to 20 ℃, inoculation and pit entry fermentation operated, after 4～5 d fermentation, the temperature rose from 18 ℃ to about 40 ℃, the utilization rate of sugar reached 47.

In reality, the regional advantages and the production modes for sweet sorghum industrialization were decided by the property change of sweet sorghum stalk under different storage conditions.

Refining fuel ethanol from sweet sorghum stalk is in the ascendant.

Effect of ultrasonic-assisted pretreatment on enzymatic hydrolysis of sweet sorghum straw;

Without ultrasonic-assisted pretreatment the hydrolysis rate of beet, sweet sorghum straw and sugarcane were24.
