A joint project between KL Energy Corp. and Petrobras America Inc., a subsidiary of Brazil’s state-run oil company, is converting sugar cane waste into ethanol in Upton, Wyoming. Validating the technology to take it to a commercial level is the goal, and Petrobras is investing $11 million in KL's existing facility. Sugar cane waste, called bagasse, is readily available and is being shipped to Upton from Louisiana for the project. Brazil, in addition to being a huge ethanol user and exporter, also is the world's largest sugar producer.
