Currently, in Vietnam, the production of alcohol is mainly from sugar molasses so the efficiency of alcohol production is not high, not yet taking advantage of alcohol-based preparations so the price of alcohol is more expensive than the common cost of the region.

Sugar cane sugar is a byproduct of the liquid, reddish brown sugar industry containing some minerals, metals .

A team of the Institute of Tropical Biology has succeeded in producing alcohol from tapioca residue, sliced ​​tapioca. By starch sugar technology, every 15 kg of tapioca residue or 2.5 kg of potatoes will produce 1 liter of 94.5% alcohol.

Alcohol from this agricultural waste will be cheaper than alcohol from sugar cane molasses about 20%; on the other hand, bio-products used in animal husbandry reduce environmental pollution due to drying tapioca residue.

Reportedly, the total output of cassava in Vietnam is 2.7 million tons / year. Every day a starch factory with a capacity of 200 tons / day will produce about 100 tons of tapioca residue, humidity 80%, equivalent to about 67 liters of alcohol.
