Bio-Serv Frenchtown

This small factory complex saw two different forms of use during its years in operation. In 1909, the facility was known as the Frenchtown Porcelain Works. They manufactured spark plugs and electrical ceramics. The site then switched ownership to a company called Bio-Serv. Bio-Serv was responsible for manufacturing animal diets. Their main center of operations is based out of Hunterdon County. The entire facility was demolished in the summer of 2018 to make way for luxury housing.
