With maize straw as the raw material of alcohol, the cost of the same amount of alcohol was only 0.01 times that of the others.
'On average, with only 4 tons of maize straws, I would be able to produce 1 ton of high-power alcohol and two more tons of special plant fiber pulp. Those special plant fiber pulp could be used to make paper and paperboards. Additionally, they could be even used to make burning rods and balls like honeycomb coal after being mixed with some pulverized coal and coal cinders. Finally, after the 4 tons of maize straws finished their chemical reactions, besides alcohol and plant fiber pulp, I could get hundreds of kgs' organic fertilizers.'
