Advisory Board

Over the past several years, the Board was instrumental in the development of a well-rounded conference focused on applied technologies for the treatment of heavy metal and organic wastes. For 2017, the Conference has an expanded redevelopment program with an emphasis on industrial, manufacturing and logistics-oriented sites. As representatives of the different vested stakeholders, the Board ensures the RE3 Conference is relevant and timely to the needs of engineers, contractors, developers, public and elected officials and other professionals in the field. A conference for the industry, by the industry.
