WR Grace/Zonolite Co. produced on this site vermiculite-based products containing asbestos

The former WR Grace/Zonolite Co. facility, where asbestos products were manufactured, is located at 35 Industrial Drive, Hamilton Township, Mercer County, New Jersey 08619.

The property is identified on the current Hamilton Township tax map as Block 1581/Lot 19. The former block/lot designation was Block 46/Lot 3. This industrial site consists of two parcels of land, one owned by MLB and presently leased to ADDI, and the other currently owned by Amtrak.

The overall site is approximately 8.4 acres and contains a large one-story brick building with an office portion, a warehouse structure housing paper and cardboard recycling machines, and a loading dock for off-site shipment of baled paper and cardboard products. The remaining portions of this industrial property are a parking lot and a heavily wooded area with dense undergrowth vegetation.

The property formerly leased by WR Grace consisted of 8.4 acres and has since been subdivided into two parcels. One parcel, now identified as Lot 19.01, is 4.24 acres and is owned by MLB. The other parcel, Lot 19.02, is 4.17 acres and is still owned by Amtrak railroad. The properties are bordered on the east by railroad tracks, the Amtrak "Millham yard" (Block 1508/Lot 17) to the north and east, a vacant lot to the west, and commercial buildings and other industrial properties to the south and southwest.

The Zonolite Company originally leased the Site property from Penn Central Transportation Corp. (Penn Central) for the time period 1948 - 1963. W.R. Grace subsequently acquired the Zonolite Company through a merger in April 1963, while also leasing the same Penn Central property at 35 Industrial Drive from 1963 to 1994.

Both the Zonolite Co. and WR Grace utilized the Site to make vermiculite-based products such as structural fireproofing, thermal insulation for masonry products, lightweight concrete aggregates, and horticultural vermiculite. Most of the raw vermiculite concentrates (unexpanded) were received from the Zonolite/WR Grace mine in Libby, Montana.
