BP’s Archaea Energy just flipped the switch on two new renewable natural gas (RNG) plants in southern Ohio—one at the Beech Hollow Landfill in Wellston and another at the Pike Sanitation Landfill in Waverly. These facilities, situated about 40 minutes apart and operated by Rumpke Waste & Recycling, aim to capture methane emissions from decomposing waste and convert them into RNG using Archaea’s Modular Design (AMD) technology.
The Promise: Turning Trash into Treasure
Together, these plants can process up to 6,200 standard cubic feet per minute (scfm) of landfill gas, enough to heat approximately 25,000 homes annually, according to EPA estimates. The Beech Hollow facility handles 3,200 scfm, while Pike Sanitation manages 2,000 scfm. Archaea’s AMD system employs standardized, skid-mounted modules, potentially reducing construction time and costs compared to traditional custom-built RNG plants.
The Pitfalls: Environmental and Community Concerns
While capturing landfill methane is touted as a climate solution, the reality is more nuanced. Methane is a potent greenhouse gas, with a global warming potential at least 28 times greater than CO₂ over a 100-year period. Although RNG projects can capture a significant portion of methane emissions, they don't eliminate them entirely. The EPA estimates that landfill gas energy projects can capture roughly 60 to 90 percent of methane emitted from landfills, depending on system design and effectiveness .
Moreover, the presence of RNG facilities doesn't address the root cause: excessive waste generation. Landfills remain a significant source of methane emissions, and relying on them for energy can perpetuate a waste-heavy system. Critics argue that this approach may delay a true shift to zero-waste alternatives and more sustainable waste management practices.
Communities near these landfills may also continue to face challenges. Landfill gas contains not only methane but also other pollutants like volatile organic compounds (VOCs) and hydrogen sulfide, which can contribute to odors and potential health risks . While RNG projects aim to mitigate these issues, the effectiveness can vary, and residents may still bear the brunt of environmental and health impacts.
The Bottom Line: A Partial Solution
BP's RNG plants in Ohio represent a step toward reducing methane emissions from landfills. However, they are not a panacea. Addressing the broader issues of waste generation and implementing comprehensive waste reduction strategies are essential for meaningful environmental progress. RNG can play a role in a diversified approach to energy and waste management, but it should not be viewed as a standalone solution.
