The Environmental Research & Education Foundation (EREF) will hold charitable auctions, one silent and one energetic and live, during Waste Expo 2013 in New Orleands (May 20 – 23). Silent auction bidding is open May 6 – 17 online and again May 21 – 22 in the exhibition hall. The live auction will be held May 22 following a reception in the early evening. EREF’s mission is to fund and direct scientific research and educational initiatives for waste management practices. To date, the annual auction has raised more than $13 million to fund the foundation’s initiatives.
