Garden State Paper Co. Inc. (GSP), of Garfield, NJ, pioneered de-inking technology. It is the first large-scale maker of recycled newsprint, manufacturing entirely from old newspapers. The company, founded by former newspaper publisher Richard Scudder, is a Media General subsidiary.

GSP has several paper recycling facilities along the East Coast to recycle newspapers for its many newspaper publishing facilities. Since landfills are closing each year in New Jersey, the legislature has mandated the recycling of paper, glass, metal, and plastics. Garden State needed a regional facility, and the industrial park became a prime location for such a plant. The tenant’s occupancy schedule was met through tilt-up concrete construction, enabling the project to be completed in just five months. Only two columns were used in the interior, and steel joist girders gave clear spans of sixty feet in one direction and seventy feet in the other direction. The second such method was used in the park.

The facility's design includes a reception area, administrative offices, loading docks, and site improvements, including landscaping. These features support operational efficiency and visitor experience.

The Mine Hill Paper Recycling Facility now operates as Trinity Paper Recycling Center. It is a Class 'A' Recycling Facility with a capacity of 20,000 tons per year. The facility handles corrugated cardboard, mixed office paper, and newspaper.
