In many ways, renewable natural gas is the ultimate form of recycling. The energy industry has been using it to generate electricity or fuel vehicles for decades, but here's a new concept: injecting RNG into pipelines for direct use in our homes and businesses. It's happening here--and around the word--and the sources are closer than you think.
When it comes to natural gas, the word "fossil" might no longer be accurate to describe the natural gas flowing through pipeline networks.
For years, some utilities have been capturing greenhouse gas emissions from decaying organic materials in landfills, wastewater treatment plants, farms and other sources and using it to generate electricity and fuel vehicles rather than letting it simply float into the atmosphere or be flared.
