In December it collected 400 tons of reusable items.
The green goal comes after the department rolled out single-stream recycling last year.
Just before Thanksgiving, workers delivered 65 and 95 gallon carts to people's homes.
Public Works Director Jim Karch says the added space to toss plastics, paper and glass is encouraging more people to change their habits.
Each bin is equipped with a sheet telling residents what to throw in, and what to keep out.
"On the lid there's sticker," Karch said. "Take a look at the sticker try to find out what different items you can start recycling more. That's really where we're going to see that next level because we can do even better."
The city is in the process of ordering more recycle carts.
So far, 65 percent of residents are taking part in the program.
