An environmentally friendly and cost-effective solution to the disposal of oily sludge waste has been developed by engineers, microbiologists, and chemists from Naval Facilities Engineering Command Hawaii (NAVFAC) Hawaii and NAVFAC Engineering Service Center (ESC). The solution makes it possible to remediate oily sludge waste at Pearl Harbor instead of shipping it to the mainland for disposal, which is a large cost burden and liability for the Navy. Remediating the waste is also a sustainable practice. Natural elements and processes are used, and the by-products of the remediation are natural and harmless to the environment. The oily sludge waste remediation project began as a pilot study in 2004 at the Bilge Water/Oily Waste Treatment Facility at Pearl Harbor.
