Boston-based Ze-gen Inc. named Richard Steiger as vice president of engineering and construction. In this capacity, he will oversee the company's project-specific engineering activities, including the operation of a demonstration-scale facility in New Bedford, Mass., that gasifies municipal solid waste into synthesis gas. He will also supervise the construction and operation of Ze-gen's first commercial-scale facility, which is expected to come on line in the first quarter of 2011. The company is negotiating two or three locations, Steiger said.
