Turning waste into a resource with cost-effective and sustainable technologies. At Fluence, we have more than 30 years of experience in the design, construction, and operation of waste-to-energy plants for a wide range of industrial and municipal clients. Our proprietary anaerobic treatment technologies process wastewater and sludge to produce biogas, which can be used to produce electricity and thermal energy, or which can be purified to produce biomethane for injection into the grid.
