Westchester County is offering to take away restaurants' used cooking oil for free and use it to fuel vehicles and heat buildings.
Westchester County Executive Andrew Spano said the county can save $25,000 with every 10,000 gallons of oil it collects, while helping the environment.
"This is not chump change," Spano said.
The county has a cooking oil-fueled, conservation-promoting vehicle called the Veggie Van and has renovated seven trucks to run on the oil. It's using 10 percent vegetable oil in the heating fuel at a county garage and has plans to expand the program.
