March 2013, Honda finished construction on a new 250,000-vehicle plant in Saitama, Japan. Set to begin operating in July, the Yorii Plant is not only a state-of-the-art manufacturing compound boasting world-leading energy efficiency and the most advanced equipment available, but, with more than 30% of its land area devoted to vegetation and riparian habitat, it is also ecologically responsible, specially designed for building harmonious relationships with the surrounding human and biological communities.
In July 2010, Honda announced that the Yorii Plant will be indispensable in efforts to establish the highly sophisticated next-generation manufacturing technologies necessary for the production of environmentally responsible products and development of low-carbon manufacturing. Equipped and designed to function as one of the leader plants in Japan of Honda's manufacturing sites in 27 countries, the Yorii Plant is absolutely packed with cutting-edge environmental technologies.
● Product specialization yields 30% reduction in energy use
Customizing the plant for production of compact vehicles.such as the new Fit to be released this year.and loading it with dedicated machinery and technologies has resulted in an extremely efficient production system. In fact, combined with the latest energy conservation and management technologies, this system uses 30% less energy per unit1.
● 2.6 MW of solar power.the most of any auto factory in Japan
Installation of Honda Soltec-brand CIGS thin-film solar panels on rooftops and other surfaces is underway, with plans to increase total generation capacity to 2.6 MW by August 2013.the most of any auto factory in Japan. This is enough to power 459 typical Japanese homes2, and should cut CO2 emissions by roughly 1,200 tons per year.
● Produces 28% of the energy it uses through cogeneration
Faced with nationwide restrictions on electricity use following the 2011 disaster, the Yorii Plant was equipped with a natural gas-powered cogeneration system that will meet 28% of its electrical and thermal energy needs, reducing the plant's peak power demand by 45%. Using energy from the system, which is about twice as efficient as energy from the grid, will cut emissions by roughly 3,000 t-CO2 per year.
● New paint technologies reduce CO2 emissions by 40%
Body coating processes at the Yorii Plant will use a newly developed paint technology called Honda Smart Ecological Paint as well as a newly developed wall-mounted robotic painting system. These innovations result in a 40% shorter coating line and 40% fewer CO2 emissions compared to conventional lines.
