Open-air burn pits have long been used to dispose waste at military sites. A wide range of materials like chemicals, human waste, munitions, unexploded ordnance, petroleum products, medical and food waste used to be burned directly in open burn pits. Such uncontrolled burning can produce toxic combustion products like CO, NOx, SOx, ammonia and many hazardous organic compounds and fine particulate matter. Exposure to these toxic materials can seriously affect respiratory and cardiovascular systems, skin, and internal organs. The report prepared by National Academy of Sciences in 2011 on long-term health consequences of exposure to burn pits in Iraq and Afghanistan found ‘limited but suggestive evidence of a link’ between health issues and exposure to the burn pits. The scientifically designed burn pits equipped with Flame Refluxers, will ensure complete combustion, and can largely reduce the health and environmental problems associated with open burn pits. The short term benefit of the technology is the fast and efficient waste incineration that promotes increased operation speed in remote locations. For long term, the clean combustion will reduce the health problems and the medical expenses for the veterans exposed to pit burns.
