NEW YORK (MainStreet) — You say you like that new car smell? Well, take a whiff of this: Toyota will soon use local landfill waste gas to build cars – it's a process the company says will supply enough power each year to produce 10,000 vehicles.

Toyota's Georgetown, Kentucky manufacturing plant will utilize a network of wells to collect and prepare landfill gas, which is naturally produced by the deterioration of solid waste. Comprised of about 50% methane, the gas will fuel generators for electricity that will then be routed through underground transmission lines to the manufacturing plant, located a few miles south of the landfill.

Toyota says the system will generate one megawatt of electricity per hour – enough to power the equivalent of 800 homes, based on average consumption in the U.S. Meanwhile, landfill greenhouse gas emissions will be cut by as much as 90%, according to the company.

Construction on the power plant will begin next month, with completion targeted for early 2015. The Kentucky plant has also been a "zero-landfill" facility since 2006, meaning any waste generated at the plant gets repurposed instead of rejected. Some of the waste goes into a composter, used to fertilize an on-site garden. Situated on the manufacturing plant's 1300-acre campus, the garden supplies 11,000 pounds of produce each year that is donated to a local food bank.

The Kentucky plant built the first American-made Camry in 1988. Since then, nearly 10 million vehicles have rolled off the assembly line. The facility employs 7,000 full-time workers and also builds the Avalon and Venza, as well as four-cylinder and V-6 engines. Beginning in late 2015, the plant will begin production of the first U.S.-assembled Lexus, adding 50,000 vehicles to its current annual capacity of 500,000 units.
