In cooperation with the US Army Research Development and Engineering Command (RDECOM), Army Research Lab (ARL) and US Air Force Civil Engineer Center (AFCEC), Eco Waste Solutions (EWS), http://ecosolutions.com, demonstrated a Deployable Waste-to-Energy Conversion (DWEC) system at Tyndall Air Force Base, Florida, on January 12, 2017.  The event provided Government and industry personnel a first-hand demonstration of simple and effective destruction of waste as well as the production of hot water.

The DWEC evolved from systems EWS currently produces for military and civilian use and represents a more cost effective and efficient system especially designed or expeditionary waste disposal.  Combined with the optional Heat Energy Recovery System (HERS), the DWEC produces a net energy benefit in the form of potable hot water for showers, kitchens, or laundry. The DWEC is a simple, easy to use, containerized waste management system that can be deployed for use at a forward operating base (FOB) to manage waste on-site without the air pollution and health effects of open-pit burning.  The system requires less fossil fuel, has a lower logistical footprint, and produces a net energy benefit.  The system had undergone previous testing by the Contingency Base Waste-to-Energy Standardized Testing Program of the U.S. Army Natick Soldier Research Development and Engineering Center (NSRDEC) and ARL with the cooperation of the AFCEC.

Problem

Department of Defense (DOD) forward operations generate significant amounts of waste that must be treated properly to avoid exposure of personnel to the waste and its inherent hazards. Expedient methods such as burn pits pollute the air, water, and land and can have a long-term impact on the troops as well as the local population. Incinerators are the only proven commercial systems that reliably address this problem. However, those currently available do not meet emerging requirements for resource and energy efficiencies. Improvements to existing designs are needed to lower fuel consumption, reduce the logistical footprint, and recover energy.

Approach

The Eco Mobile™, DWEC is a simple, easy to use, containerized waste management system that can be deployed for use at a forward operating base to manage waste on-site without the air pollution and health effects of open-pit burning. The DWEC requires less fuel, has a smaller logistical footprint than systems currently in use, and it produces a net energy benefit. The DWEC is evolved from the systems Eco Waste Solutions (EWS) currently produces for military and civilian use and represents a more cost effective and efficient system, especially designed for expeditionary waste disposal. Combined with the optional Heat Energy Recovery System (HERS) the DWEC produces a net energy benefit in the form of potable hot water for showers, kitchens or laundry.

Results

  1. Installed and operational within 1 day, requiring only 2 persons.
  2. Each Tricon-module weighs less than 10,000 lbs, can be lifted using a forklift.
  3. Meets 100% of the waste disposal needs of a 150-250 person base camp.
  4. Produces enough energy to deliver all of the hot water needs for hygiene, kitchen, laundry and other uses for a 250 person camp. (Replaces the need to use JP8-fired hot water heaters.)
  5. Uses 50% less fuel than comparable waste disposal systems.
  6. Best-in-class air emissions.
  7. Waste volume reduced by over 96%. Ash residue is non-hazardous.

Specifications

  • Waste Processing Rate:  1000 lbs of solid non-hazardous military base waste in 24 hours
  • Volume Reduction:          > 96%
  • Labor Requirement:         One person for 1 to 2 hours per day for inspection, loading and ash removal. (Not required to attend the system during operation.)
  • Energy Savings:               Uses 50% less fuel than comparably-sized systems fielded today
  • Energy Production:         Up to 3000 gallons per day of hot water (ÄT=84°F) saving 20 gallons of fuel per day
  • Optional Features:          Capability to use waste oil as a fuel

Configuration

The waste disposal module is designed to operate with or without the energy recovery module.

DWEC Waste Disposal Unit (Eco Mobile™): 3 interconnecting Tricon ISO containers (<10,000 lbs each). Footprint: 20’ x 8’ x 8’
HERS Energy Recovery Feature: 3 interconnecting Tricon ISO containers (<10,000 lbs each). Footprint: 20’ x 8’ x 8’ (tank modules not shown)

Process Description

The Eco Mobile /DWEC process is significantly different from traditional incineration as it produces dramatically lower air emissions. The process utilizes EWS' proprietary waste conversion technology: starved air gasification of the waste followed by an excess air oxidation of the gas generated in the conversion process, with a unique process control system that automates every aspect of the process.
