Green Energy
U.S. Sugar is committed to powering its facilities with clean, renewable energy and the Company makes the investments necessary to carry out that goal.

Green Energy Bagasse
Bagasse is the fibrous matter that remains after sugarcane stalks are crushed to extract their juice. U.S. Sugar uses this residual product as a clean burning biofuel.

In 2003, U.S. Sugar began construction of Boiler 8 as part of the Company’s “Breakthrough Project” – a company-wide initiative to radically transform its sugar processing facilities through consolidation and high tech automation.

The Boiler 8 produces steam during the milling process by burning bagasse. Steam is co-generated into electricity on-site. In essence, each year’s cane crop provides power for both the sugar factory and U.S. Sugar’s refinery operations.

Boiler 8 began operations in 2005. With a maximum heat input rate of 1030 MMBtu/hour and a maximum continuous steam production capacity (24-hour average) 500,000 pounds/hour, and has consistently and efficiently operated with a high standard of emissions control, according to Thermal Energy Systems, the company that engineered the equipment.

The initial cost of a bagasse-fired boiler was $15-20 million. However, in the United States, emission-control equipment costs roughly the same as the installation of the boiler itself, therefore doubling the cost of power generation boilers compared to similar boilers in many other sugar producing countries.

In 2006, the Boiler 8 project was awarded the Energy Institute’s prestigious Environment Award for setting a new standard in emissions control performance. For every ton of bagasse can produce the same amount of energy as 50 gallons of oil.

Ethanol
In 2008, U.S. Sugar Corp. entered into an agreement with Coskata, Inc. of Warrenville, IL to explore building a 100 million gallon per year cellulosic ethanol facility in Clewiston, Florida. The facility would be the world’s largest second-generation ethanol facility. It would convert leftover sugar cane material into ethanol and would help Florida meet its aggressive second-generation ethanol goals.

Exploration of this technology complements the Company’s existing sugar factory operations and benefits the environment. The non-food based ethanol could reduce greenhouse gasses by as much as 96% versus conventional gasoline.
