time Norwesco was ranked as one of the oldest and largest plastic processors in the United States.
Norwesco had been a publicly traded company until January 1988 when Norwesco, Inc. was acquired and taken private by its management and private equity investors. In 2008 they were acquired by Olympus Partners and became part of Tank Holding Company along with tank manufacturer Snyder Industries. Their current financial partner is Leonard Green & Partners, L.P.

Norwesco's rotational molding of tanks began in 1980 with a single plant in St. Bonifacius, Minnesota. Now, that plant is the headquarters for thirteen additional manufacturing facilities across the U.S. and Canada.
