If recovery is the process of recycling can be profitable bagasse millions of dollars each year.
Value product is less than 10%
In 2004, Lam Son Sugar Factory (now the Lam Son Sugar JSC-LLS) is the first in the industry to invest 10 million US dollars (about 165 billion calculated at the exchange rate at the time) plant ethanol from sugarcane residues and Privacy rust.
The specifications of this project demonstrated, with a capacity of 85,000 tonnes of cane per year plant produces about 20 million liters of alcohol, bringing hundreds of billion of revenue, contributing significantly reduced price the way for LLS. 2010-2011 year, revenue from the sale of alcoholic LLS over 300 billion, accounting for 9.6% of total sales of 1,500 billion.
However, after many years of operation, until now, when evaluating the effectiveness of this project, Mr. Tam said the outspoken earned value is too low, is not commensurate with the amount of initial investment. Because of the 300 billion revenue from alcohol for that year, the president said, the cost of money processing environment has to occupy more than 100 billion.
Following an additional LLS Quang Ngai sugar factory, sugar factory Tuy Hoa Hiep Hoa Sugar Factory hundred billion investment in technology to cook the alcohol. But, as LLS, the values obtained from the by-products are not enough to offset costs, some plants such as Quang Ngai, Hiep Hoa had to stop or idle.
As the president of Sugar Association, direct and manage the sugar factory in Can Tho, Nguyen Thanh Long admits this is the weakness of the sugar industry in Vietnam.

As the president of Sugar Association, direct and manage the sugar factory in Can Tho, Nguyen Thanh Long admits this is the weakness of the sugar industry in Vietnam.
According to Mr. Long, conventional, by-products collected from sugar processing activities include bagasse (25-30% by weight of pressed cane brought), bile rust (representing 3-5%), sludge (1, 5-3%). Some parts of this work, if properly invested, will yield a higher value product is sugar.
Such as bagasse used as raw material of furnace generate electric power, pulp, pressed into boards for use in architecture; Privacy stainless fermented ethanol; sludge fertilizer for sugar cane land improvement ... However, due to many different causes, only sugar mills to exploit the value from the sale of products such as electricity, Privacy rust, alcohol ... less than 10 %.
Claiming ventilation mechanism
Some suggested that the reason the sugar mills untapped value byproducts, mainly due to the current state does not have mechanisms and policies to encourage the use of renewable energy.
Agree with the management point of view, Le Van Tam said, since 2004, although LLS has seen effective investment in building ethanol plants, but the reality so far, in Vietnam did not form the legal framework for mandatory rate used biofuel (made from alcohol) in fuel.
This condition causes the output, the price of alcohol sold more than 20 million liters annually usually obtained low and unstable, so spending hundreds of billion of investment, such as LLS and other businesses do not have effective .
In Vietnam, EVN's monopoly in the purchase of electricity from bagasse do not see power as renewable energy. Thus making the purchase prices are too low (less than 4.4 cents / kWh, while they bought from China for 7 cents and PVN (Petro VN) cost 9 cents / kWh).
In documents recently submitted to the Government Prime stripped, Vietnam Sugar Association calculations, if the right investment in technology high pressure boiler turbine, then for every tonne of cane processed will produce a surplus of electricity at least 100Kwh generate net (after adequate supply of energy required for processing of sugar chains).
With this calculation, the potential of power from renewable energy by investing bagasse apply new technology in 40 sugar mills will produce 1.950MW (2010, with output of 19.5 million tons of sugarcane) and 2,400 2020 MW (equivalent to 24 million tons of cane); enough to take on almost 10% of electricity generation for the country.
