Methane Gas from Landfill Fuels Arts Complex

The commissioners of Jackson County in North Carolina knew they needed to do something about the growing levels of methane gas within the nine-acre landfill in Dillsboro. The landfill had closed in 1999, with roughly 750,000 tons of trash enclosed, and the buildup of methane gas had the potential of leaching into the soil and contaminating the water supply.

Although an environmental firm advised them to flare it off, which would allow them to burn off the flammable gas, the commissioners had a different plan.

“The county manager came to me because he knew I had a background in renewable energy,” explains Timm Muth, project director for the Jackson County Green Energy Park. “There was enough [gas] there to [power] a community project, so I suggested they put in art studios and use it to heat buildings.”

Knowing that methane gas can be used for heating in the same way as propane and natural gas, Muth helped create Green Energy Park, which has not only provided an environmentally friendly use for the gas, but has also helped revitalize the entire area.

Although he had moved to Jackson County to retire and become a professional mountain bike guide, Muth knew that his skills would add value to the project — so he re-entered the work force. “This is a tourist-driven economy, and I knew if we could do something that promoted our local artists, we would have a win-win situation,” Muth says. “Methane is more than 20 times worse than CO2 in terms of greenhouse gas effects, and for us it has provided a cost-free fuel.”

Today, the methane gas from the landfill provides power to a blacksmithing shop, a glass studio, a ceramics kiln and an art gallery. The park also is home to greenhouses, which the county uses to grow plants, and a sculpture garden that features works by local artists.

Say goodbye to Yosemite’s largest glacier

Say goodbye to Yosemite’s largest glacier

Park visitors gaze at what remains of the Lyell Glacier.

Hasta la vista, glacier.

The world’s glaciers are withering quickly — researchers say they are contributing to nearly one-third of sea-level rise, despite holding just 1 percent of the planet’s surface ice. And while the glaciers in California’s Yosemite National Park aren’t the largest, they are suffering the same alarming fate as their icy ilk in other parts of the world.

Yosemite’s granite cliffs and valleys were carved during the Ice Age as glaciers expanded. Now these vestigial masses of ice are mostly retreating — and fast. The park employs a full-time glaciologist, Greg Stock, who recently returned from a trek to Lyell Glacier, which is the park’s largest. He told the L.A. Times that it had shrunk visibly since he made the same back-country hike last year:

Lyell has dropped 62% of its mass and lost 120 vertical feet of ice over the last 100 years. “We give it 20 years or so of existence —  then it’ll vanish, leaving behind rocky debris,” Stock said. …

Yosemite’s other glacier, Maclure, is also shrinking, but it remains alive and continues to creep at a rate of about an inch a day.

Lyell, however, hasn’t budged. It is the second largest glacier in the Sierra Nevada and the headwater of the Tuolumne River watershed, but it no longer fits the definition of a glacier because it has ceased moving.

“Lyell Glacier is stagnant — a clear sign it’s dying,” Stock said. “Our research indicates it stopped moving about a decade ago.”

Stock warned that when the glaciers disappear, steady water supplies that feed the park’s meadows and other ecosystems will disappear with them. ”We don’t know what the impacts of that will be on plants and animals that evolved with these ice flows,” he told the newspaper.
