Supplying green value
ConNRG facilitates the conversion of waste and residues into renewable energy by linking waste producers with RNG producers and providing high-quality feedstock for biogas and biomethane production.
We collect and move
renewable feedstocks
We source and supply waste and residues to anaerobic bio-digesters, enabling the efficient and economically viable production of biogas and biomethane (green gas). In doing so, we help our partners meet their sustainability goals and contribute to reducing carbon emissions across transportation, heavy industry, agriculture, and residential energy use.
