Ten of 14 North American Honda plants have achieved landfill-free status, the automaker said today.

The remaining four plants are functioning with “virtually zero” waste to landfill, the company said.

Landfill-free plants in Ohio include the Anna Engine Plant and the Honda Transmission Manufacturing of America plant in Russells Point, according to a Honda spokesman in Ohio.

The Marysville and East Liberty plants “are very close to zero waste to landfill,” the spokesman said.

Waste sent to landfills has been reduced at Honda auto plants from 62.8 pounds of industrial waste for every automobile made in the fiscal year ended March 31, 2001, to an estimated 1.8 pounds per automobile in the current fiscal year 2012, the company said.

Engine plants in Ohio, Alabama and Canada are reusing virtually all leftover sand from aluminum and ferrous metal casting operations, Honda said. And no steel scrap from North American manufacturing operations has been going to landfills, the company said.

Honda has about 13,000 employees in Ohio, with about 1,300 from the Dayton area, which includes about 300 at a Troy distribution center.
