Case Study: Naval Surface Warfare Center

The plastic blast media used to remove paint from this aircraft propeller is more efficient than the previous material used, and is also recyclable.

At the Naval Surface Warfare Center in Washington DC, a strategy was developed to build and operate ships that were more environmentally friendly across their lifetimes.

An environmental management system was implemented to minimize the environmental and health risks that occur during the ship design, construction, operation, maintenance and disposal.

Many of the 93 hazardous materials previously used have been eliminated or must now be used in limited amounts and under strict guidelines.

The new T-AKE Class of ship will also reduce their waste outputs by a significant amount, including:

• 94% reduction in sewage output
• 44% reduction in greywater output
• 100% reduction in the production of volatile organic compounds
• 70% reduction in water consumption
• 65% reduction in carbon dioxide emissions
• 70% reduction in waste production - this will save 5.74 tonnes of waste being produced each year and save the navy $5 million each year in disposal costs.
