Sevenson entered the environmental cleanup business in 1979 when it was selected as the principal contractor for remediation work at the Love Canal Superfund site in Niagara Falls, New York. Today, under the leadership of The Elia Family, Sevenson Environmental is one of the America's Leading Environmental Remediation Contractors with over 1,500 projects completed - including 143 sites on the US Environmental Protection Agency's NPL Superfund list - with a combined value of over $5.5 billion. Sevenson's customers include major industrial companies and federal and state agencies. Sevenson provides services throughout the continental United States, Canada and Puerto Rico. Roots go back to 1917. In that year, Albert Elia, a Niagara Falls, New York architect, began a general construction business. In the 1940's, Elia's four sons joined the business and incorporated it as the Albert Elia Building Company, Inc. In the early 1950's it expanded into industrial, institutional and heavy civil construction work. Eventually the Albert Elia Building Company, Inc. grew into one of New York State's largest general contractors. Today the 3rd Generation of Elias led by CEO Alan R. Elia Jr, along with Co-Owners Michael, Rick & Larry Elia along with Bill McDermott are at the helm, with the 4th Generation currently working its way up through the ranks. In 2017 we celebrated our 100 year anniversary!

We provide on-site collection containers, collect the oil from their facilities and refine it into biodiesel feedstock, which is then shipped to a refinery in the US to be developed into biodiesel.
