Argonne Lab partnering with Roeslein Alternative Energy for new technology converting wastewater sludge to renewable natural gas

By USGasVehicles.com

Argonne National Laboratory (ANL) has developed technology that synergistically uses two waste biomass streams to generate two bioproducts. The technology enhances the process of anaerobic digestion of wastewater sludge by incorporating biomass-derived, carbon-sequestering char within the digester, thus creating pipeline-quality renewable natural gas while using the remaining biosolids for a high-quality fertilizer. With funding from the U.S. Department of Energy’s (DOE’s) Bioenergy Technologies Office (BETO) totaling $1.5 million over three years, researchers at ANL have been able to develop and de-risk this technology, which is now ready for scale-up.
