In January 2003, Envirogen, Inc was acquired by Shaw Environmental and Infrastructure of Louisiana. Envirogen, Inc. provides systems and services to remove pollutants from the air, water and soil. Envirogen's developmental efforts focus on the isolation of naturally occurring organisms, enhancement of their performance and the design of advanced systems to optimize their activity for the biodegradation of various compounds in soil, air and water. Envirogen's approach is to utilize the appropriate technology to provide its clients with the most efficient, safe and cost-effective solutions to hazardous waste cleanup and treatment needs. In addition to commercial remediation, a substantial portion of the activities of the Company to date has been related to research funded by corporate and governmental sponsors to determine when advanced biological treatment systems are appropriate to treat hazardous or noxious waste. The Company conducts its operations in two business segments: commercial operations, and research and development services.
