Hynite Fertilizer Plant – Oak Creek, WI


Hynite Fertilizer Factory, and the formerly adjacent Peter Cooper Glue Factory are wonderful examples of former Milwaukee Industries. In spite of conflicting reports found elsewhere, the building featured here was used for making fertilizer from 1920 until the 1970s. The property to the north contained Peter Cooper Glue, which turned the remnants of the tanning industries of Milwaukee into glue and gelatin (aka Jello). Production ended in 1985 at the Glue Factory, and a massive portion of the Glue Factory burned down in 1987. Recently, beginning in the fall of 2009, the remaining Glue building was razed. Unfortunately, I did not have a chance to visit Peter Cooper before its destruction. The Hynite Factory was the only building still standing, it was torn down in 2015
