The Hynite Company property is adjacent to the Peter Cooper building. This structure often gets confused for the Peter Cooper building. This location is mentioned in the US Department of Health & Human Services report.

The Hynite Company reportedly opened in Carrollville during the 1920s to manufacture nitrogenous fertilizers leather meal from waste leather. It is not clear to DHFS when such manufacturing halted at the Hynite property.

Tucked behind the southeast corner of the former Peter Cooper property is the 8-acre former Hynite property. Viewed from the end of East Depot Road, staff saw two buildings, a smaller, brick office with a vehicle scale on the south side, and larger multi-storied brick building estimated to be about 22,500 sq ft, with a newer 13,500 sq ft structure attached to the east side. Aerial photos of the Hynite property also show that on the northeast side of these buildings are several concrete foundation footprints of one or more prior buildings.

As of January 2010 the Peter Cooper building was under active demolition. It is a good bet that the Hynite building will meet a similar fate in the near future.
