Our Plantations
In the near future, net CO2 emissions will become an even more important issue for the ethanol industry as pressures associated with utilization of food crops and concerns over fossil fuel usage grow.
Nasamax’s policy is to manufacture only ultra-low environmental impact bio-ethanol. This is done by using advanced technologies to control both the growing and the conversion of the crop, and by using only biomass energy for the complete process. Consequently, Nasamax produces ethanol with lower CO2 emissions than any other company, regardless of type of feedstock they may use.
The Nasamax modular concept is unique. Each plantation module has control over the vital business factors including crop production, conversion to ethanol, energy supply and market timing. Plantations can encompass up to roughly 10,000 hectares (about 25,000 acres) and are designed to provide a continuous supply of raw material - enabling the adjacent refinery to produce ethanol from farm-fresh feedstock 360 days per year.
Nasamax develops plantations only in geographical areas of the world with the typography and conditions to optimize the growth and quality of its proprietary sweet sorghum crop.
