GeoEnvironment Technologies, a subsidiary of Advantek Waste Management Services, provides the cleanest, safest, and most cost-effective option for municipal biosolids disposal and industrial wastewater treatment: the deep earth digestion of biosolids. This technique is enabled by our patented slurry injection technology and allows the injection of biosolids and sludge produced by waste water treatment plants into the deep, hot earth where it decomposes into renewable methane.
