The second phase will begin in the spring, with the remainder of the 110,000 city residents receiving the blue recycling carts.
The city said it also will be using some new and retrofitted recycling collection trucks. The retrofitting of the existing fleet saved the city about $450,000, it said. Customers will pay the same amount.
Earlier in the year the city expanded the types of plastics and paper it collects for recycling to include all grades of plastic and paper cartons.
