Lighting retrofits resulted in annual savings of 17 million kilowatt hours, enough to power 1,500 average households while eliminating 10,000 tons of greenhouse gas emissions. Total cost savings topped $1.2 million.
Replaced a 20 year old oxidizer (used for odor control) with a new, more energy efficient oxidizer, improving energy efficiency by nearly 14 percent and cost savings of $75,000 annually.
Its Woodstock plant installed a cooling system using outside air to chill water during the cold season, reducing energy use by nearly two percent, resulting in saving of more than $100,000 annually. Its Cambridge plant installed linkage-less boiler burner controls, improving boiler efficiency by more than 15 percent, resulting in saving of more than $112,000 annually.
Installed an adiabatic humidification system in the paint booth improving energy efficiency by 35 percent and saving more than $1.1 million annually. An adiabatic system uses atomized high pressure water instead of steam to control humidity & temperature.
The plant also reduced paint booth downdrafts by an average of 15 percent in all manual zones saving more than $600,000 annual with zero investment.
Installed an adiabatic humidification system in the paint shop that cut steam consumption by more than 65 percent and cut total energy use by 12 percent, resulting in saving of more than $1.4 million annually.
As Toyota’s Model Sustainable Plant for the North American region, Mississippi has used innovative design and best practice techniques from other Toyota facilities to become the most energy efficient Toyota plant in the region. For example its paint shop utilizes a unique system that eliminates the need for a paint oven and installed a low pressure adiabatic humidification system.
Installed modified burner controls on a Regenerative Thermal Oxidizer (RTO), resulting in energy efficiency improvement by more than 16 percent and savings of $25,000 annually. An RTO is an industrial process for the treatment of exhaust air to destroy air pollutants emitted from the process.
Installed a compressed air metering system that cut energy use by four percent, resulting in saving of more than $300,000 annually.Additionally, Toyota has collaborated with more than 180 suppliers across North America to share energy saving ideas and best practices. Ten of Toyota’s North American manufacturing plants are zero landfill.
