• Water, energy, and waste are interconnected in complicated ways• Energy requires water to
produce• Water requires energy to
treat and transport• Waste requires energy to
transport and can be used to create energy

1. To produce as much energy on-site as they use annually;
2. To limit the consumption of freshwater resources and return water back to the same watershed so as not to deplete the groundwater and surface water resources of that region in quantity or quality; and/or
3. To reduce, reuse, and recover solid waste streams by converting them to resource values with zero solid waste to landfill.

• U.S. Department of Energy (DOE)• U.S. Environmental Protection Agency (EPA)• U.S. General Services Administration (GSA). • DOE labs, including the National Renewable
Energy Lab (NREL) and the Pacific Northwest National Lab (PNNL), are providing direct support to Army Net Zero Pilot Installations.

• Fort Carson Mattress Recycling (PDF 344 KB) Working with a local recycler, Fort Carson no longer sends any of its mattresses to a landfill. All mattresses are taken to the recycler at no cost, and the recycler ensures all materials are recycled, re-used, and or re-purposed.
• Joint Base Lewis-McChord Composting Facility (PDF 347 KB) Joint Base Lewis-McChord (JBLM) is turning organic waste resources into valuable landscaping and soil amendment products.
• Fort Polk Battery Reuse (PDF 285 KB) Seeing an opportunity to reduce battery expenditures, waste disposal costs and potential injury to soldiers, JRTC and Fort Polk personnel developed a program for the turn-in, testing and re-issue of these batteries.
• Joint Base Lewis-McChord (JBLM) Concrete and Asphalt Recycling Success Story (PDF 192.01 KB) A one-page fact sheet about concrete and asphalt recycling at Joint Base Lewis-McChord.
Energy Exchange: Federal Sustainability for the Next Decade16
• Energy:– Conduct thermal building envelope analysis– Reduce energy use through energy management control
systems – Hire resource efficiency managers – Pursue alternative financing mechanisms – Conduct energy master planning
• Water:– Maximize the use of xeriscaping – Implement leak detection on the potable water distribution
system – Maximize water recycling – Install purple pipe – Maximize use of alternate water sources
Best Practices Identified
Energy Exchange: Federal Sustainability for the Next Decade17
• Waste:– Establish a Qualified Recycling Program – Characterize and quantify waste flows – Improve purchasing practices to reduce waste at
the source – Repurpose and reuse waste through free and low-
cost opportunities – Recycle and compost waste through free and low-
cost opportunities
Best Practices Identified
Energy Exchange: Federal Sustainability for the Next Decade18
• Expand Net Zero guidelines across the board domestically
• Plans for extending Net Zero energy, waste, and water resource concepts to overseas facilities. – Including equipment and strategies for temporary
forward operating bases and mobile maneuvers as well as permanent stationary facilities.
