The Department of Defense is the world's largest user of energy. Military planners are interested in diversifying the energy/fuel portfolio so energy managers are looking at cleaner forms of energy with the ability to meet baseload power demands at military installations around the world. Over the last 10 years, the military has deployed and tested various technologies to process waste and generate power. A proven solution that can efficiently process military waste, while also generating clean, renewable energy could dramatically change the way the military handles solid waste by taking an environmental liability and creating a clean source of renewable power. In addition to the reduction of greenhouse gas emissions by diverting waste from area landfills, a waste-powered microgrid can substantially reduce the consumption of fossil fuels. This reduces the logistics of waste hauling and fuel delivery, creating a more sustainable and resilient installation. Waste-to-energy technology convert/combust municipal solid waste in an environmentally safe combustion system to generate electricity, provide district heat, and reduce the need for landfill disposal. These systems have all the required pollution controls to meet strict air quality standards. This presentation will provide an overview of waste conversion technologies used by various Services and highlight the military's interest to utilize waste as a resource to generate energy in a microgrid application. By leveraging proven technologies, the Department of Defense can achieve energy security and base resilience, while enhancing the quality of the environment. Waste will play a critical role in helping installations reduce operational costs and achieve its sustainability goals. The presentation will address: o Scalability o Fuel Production o Efficiency (conversion rate of waste to fuel) o Operational Cost o Environmental Footprint o Emissions Generated and Produced o Equipment Reliability/Lifecycle Assessment o Technical Requirements Waste disposal rates at military installations (CONUS) can range from $129-$287 per ton of solid waste. In overseas installations, the cost can be in excess of $400 per ton of solid waste. This presentation will focus on conversation technologies that have a proven operational history of 10 years with processing costs under $60 per ton of solid waste.
