Grinnell Recycling, Inc. has taken great strides in preserving our environment. We operate a DEP approved Material Recovery Facility (MRF) and Class B Recycling Center in Sparta, NJ. These operations work hand in hand to ensure all recyclable material is diverted from landfills. We accept organic and construction material which is processed into marketable commodities such as mulch, topsoil, and Recycled Concrete Aggregate (RCA).
