Waste disposal system for military operations

By Scott Jenkins |

The Micro Auto Gasification System (MAGS) is a compact solid-waste disposal system that is designed for energy-efficient operation onboard naval vessels, in forward-operating military bases and in other isolated installations. Developed by the Office of Naval Research (ONR; Arlington, Va.; www.onr.navy.mil) and Terragon Environmental Technologies Inc. (Montreal, Ont.; www.terragon.net), the MAGS uses a highly controlled pyrolysis process (diagram) to reduce up to 40 kg of as-received solid waste into synthesis gas (syngas) and inert carbonaceous material. The pyrolysis is carried out at 750°C in the MAGS’ insulated drum. The process sequesters a significant portion of carbon as char, preventing the formation of significant portions of CO2. The syngas produced is used to sustain the process, and air emissions are environmentally compliant, the ONR says. In one day, a single MAGS unit can treat the waste generated by a community of 500 people. In 2 h, the system reduces 40 kg of typical solid waste by more than 95%, ONR remarked. Materials safely destroyed by MAGS include paper, wood, plastic, chemicals, food, cloth, grease and oil, sludge, agricultural waste and others. Metals and glass are sanitized and left intact for recycling,…
