TPL, Inc. is a materials science-based technology development and commercialization company. TPL's business areas are: contract R&D, engineering services (principally in the demilitarization of conventional munitions), and commercial products. Company facilities include a 1,000 acre site, with 150 storage bunkers and 50,000ft2 of buildings, that constitutes TPL's state-of-the-art demilitarizaton facility at Fort Wingate. TPL uses space at Fort Wingate to "demilitarize" a variety of surplus munitions by breaking them down into safe, recyclable materials. Several energetic materials resource recovery and reuse contracts received by TPL under the U.S. Navy's Ordnance Reclamation Program, funded by SBIR contracts, have allowed TPL to compete successfully as a prime contractor in the U.S. Army Industrial Operations Command Demilitarization Program. TPL, Inc. has, through the SBIR/STTR program, grown from a one-person company in 1989 to an 85-person company with over $7M in annual sales. TPL is working to establish a smokeless powder from gun propellant manufacturing plant at its Fort Wingate, NM, Demilitarization Facility.
