Harnessing the Power of Renewable Natural Gas

About Us

SustainRNG℠ is an agile, entrepreneurial developer of renewable natural gas (RNG) projects in the agriculture sector formed behind proprietary methane capture technology tailored to modern manure management techniques. The company partners with dairy farmers to develop on-farm projects.

With Duke Energy as a significant and active investor in the company, SustainRNG is transforming how the agriculture sector manages manure, helping farmers be more sustainable, and leveraging the power of the agriculture sector to solve climate change.

The advanced technology employed in SustainRNG’s projects uses a specialized anaerobic digestion unit, classified as a fixed film anaerobic filter, that stratifies the flow of particles by size, facilitating the breakdown of the organic materials in manure and optimizing biogas production. SustainRNG is initially targeting use of the technology to deploy digesters on dairy farms of 3,000 to 10,000 head that use water wash-down manure management, which is currently an underserved niche in the dairy digester market.
