ToyotaUSA – Toyota will use gas generated from a landfill site close to its factory in Georgetown, Kentucky, to power vehicle production.
The gas is created as the solid landfill waste breaks down. This is then captured in a network of wells and used to fuel electricity generators. The power will be fed by underground lines to the Toyota plant a few miles away.
When working at full capacity, the system will generate one megawatt of electricity an hour (approximately enough to power 800 average American homes) and reduce greenhouse gas emissions from the landfill site by as much as 90%, improving local air quality.

The system is expected to become operational early in 2015, producing enough power to build around 10,000 vehicles a year.
