feedstock for a renewable source.” The technology quickly converts the landfill’s garbage into methane gas, which is sold to Atmos Energy and pumped into pipelines. That’s espe- cially noteworthy when you consider our landfill was the first in the state to use the technology, and only one of about 20 in the nation — the largest, in fact — using it today. Think of it as “composting on a larger basis,” says sanitation services director Mary Nix. In that sense, the idea is “easily 100 years old or older.” But in terms of applying bioreactor technology to landfills, she says, that began in the early ’80s. Converting garbage into methane gas isn’t a new idea — trash will eventually break down and create methane, and some landfills burn it off while others trap and use it. Smith has opted to take this one step further, implementing technology to help the Dallas landfill’s trash create methane even faster than it would if left alone. Because the technology creates methane more quickly, it translates into more revenue for the city. The landfill produces 5.5 million cubic feet of gas daily. Nix says the city expects to net a little more than $800,000 in methane sales during 2009. (The city did not make any money on methane last year because until 2008, any profits went to the methane processing plant’s investor — T. Boone Pickens’ company, Dallas Clean Energy — which assumed all risk, costs and profits for construct- ing and operating the plan for the first 15 years.) The biotechnology has been under- way for about a year at McCommas Bluff, but it could be another year before we begin to see measurable results, Smith says. The landfill has 30-acre chunks of land called cells, and right now, bioreactor technology is being used only in one cell at a time. The hope is that it be used for every cell in the future. Here’s how it works, in a nutshell. Start with 996 acres of land dedi- cated to dealing with the city’s waste (accepting about 2 million tons of trash per year, the McCommas Bluff is Texas’ biggest dump).
