SustainRNG was born out of the confluence of two developments in the agriculture marketplace.
The first development is the growing demand for increased sustainability, especially in the dairy sector. For example, in response to consumer demand for milk that comes from humane, healthy, and environmentally responsible farms, major brands such as Walmart and Nestle have set ambitious goals for milk to be sustainably sourced. Also, the dairy sector itself has established the goal of achieving net zero carbons emissions by 2050 as farmers across the country seek better ways to manage their manure.
The second development was a breakthrough by Trane Technologies, a leading sustainable technology company. A well-designed anaerobic digester can convert manure into renewable natural gas (RNG) that can be captured and injected in the existing natural gas pipeline network. Trane invented the Advanced Methane Generation (AMG) technology that stratifies organic particles in the manure effluent by size before entering a Parallel Flow Digester, which is unique to the Trane process. Since increased surface area of smaller particles facilitates the breakdown of organic material, Trane’s innovation dramatically increases RNG generation rates.
Trane approached Clean Source Capital to help bring its AMG technology to market. In response, Clean Source Capital developed a business model to partner with dairy farmers to develop on-farm renewable natural gas projects, and formed and capitalized SustainRNG as the business entity to commercialize Trane’s technology.
SustainRNG has a two-part mission,
SustainRNG’s business model is to develop, design, engineer, finance, construct, and operate renewable natural gas generation projects in partnership with dairy farmers. Our vision is that our work with farmers plays a critical role to help the dairy industry meet its net zero carbon goal.
