Our Liquid Direct Injection technology destroys contaminants and materials in a wide range of waste streams. We inject liquid waste directly into our advanced controlled combustion systems where the water is instantly vaporized and the remaining contaminants and materials are destroyed. Clean oil products are collected and reused or sold.
