Toyota Motor Manufacturing, Missouri (TMMMO)

Cylinder heads are a vital component to every vehicle that Toyota assembles. Cylinder heads are like the lungs of engine. They’re key to controlling air flow in and out of the cylinders and fuel deployment. Toyota Motor Manufacturing, Missouri (TMMMO) uses recycled aluminum to build thousands of cylinder heads per day. Nearly 1,000 employees make more than 2 million cylinder heads per year — that’s the equivalent of 11,600 per day. The sustainable nature of these parts is just one of many ways TMMMO is helping to reduce its carbon footprint.
