Naval Materials Research Laboratory (NMRL) is an Indian defence laboratory of the Defence Research and Development Organisation (DRDO). Located at Ambernath, in Thane district, Maharashtra. It develops materials and alloys for Naval use, and is a single-window agency for all materials requirement of the Indian Navy. NMRL is organized under the Naval Research & Development Directorate of DRDO. The present director of NMRL is Dr Manoranjan Patri.


NMRL was established in 1953 as the Naval Chemical and Metallurgical Laboratory, an in-house laboratory of the Navy, located at the Naval Dockyard, Mumbai. It was brought under the administrative control of DRDO in the early 1960s.[1] The laboratory is located in its own technical-cum residential complex at Ambernath, Maharashtra. The laboratory still has its erstwhile infrastructure intact in Naval Dockyard, Mumbai, without any physical scientific or administrative presence.

Projects and Products[edit]

Technologies for Civilian use[edit]

  • Bio-emulsifier - for Bio-remediation of floating oil.
  • Arsenic removal kit - NMRL has developed a low-cost arsenic removal filter to remove arsenic from contaminated drinking water. The filter is made of stainless steel, and the filter medium is a processed waste of the steel industry. The filter works on the principle of co-precipitation and adsorption, which is followed by filtration through treated sand. The complete filter costs Rs. 500, has a life of 5 years and does not require any electricity to run. After six months of testing in 24 Paraganas District in West Bengal, the technology was given to NGOs for productionizing.[4]
