Dayton, Ohio – The City of Dayton Department of Water has implemented cutting-edge systems at its Guthrie Road reclamation plant, significantly reducing the city’s carbon footprint while generating revenue through the sale of renewable natural gas. This innovative initiative reflects Dayton’s commitment to sustainability and efficient resource use.
Transforming Biogas into Renewable Energy
In collaboration with DTE Biomass Energy, the water reclamation facility is now capturing and processing digester gas, which was previously flared, to produce renewable natural gas (RNG) suitable for sale. Over the past year, DTE installed advanced infrastructure and technology that allows the digester gas to be conveyed to an off-site treatment facility. At this facility, the gas undergoes purification to meet pipeline-quality standards.
The facility processes millions of gallons of wastewater daily from residential, commercial, and industrial customers across Dayton and parts of Montgomery County. Anaerobic digestion, the key process at the plant, uses microbials to break down organic waste in wastewater solids. This process generates biogas as a by-product, primarily composed of methane, carbon dioxide, and trace gases. Previously, excess gas was burned to heat the digesters and campus buildings, with surplus gas flared.
Now, with the new system, all biogas is captured and treated, converting it into valuable renewable natural gas instead of flaring it.
Cutting Carbon Emissions in Half
This new operation is expected to reduce carbon emissions from Dayton municipal facilities by 50%. By capturing and utilizing the gas, the facility not only minimizes environmental impact but also aligns with broader climate goals to transition to cleaner energy sources.
A Financial Boost for the City
The initiative also represents a financial milestone for Dayton. The city anticipates net revenue of $800,000 annually for the 20-year contract period, totaling $16 million based on market conditions. These funds bolster Dayton’s financial performance while supporting its sustainability goals.
A Commitment to Sustainability
City Manager Shelley Dickstein expressed pride in the new system, saying, “The City of Dayton is proud to launch a sustainability-focused innovation that will result in enhanced financial performance and reduced environmental impact.”
This project underscores Dayton’s leadership in environmental stewardship and innovation, setting a model for other municipalities to follow. By combining sustainability with financial viability, the city is ensuring a greener, more prosperous future for its community.
