Monroe County Executive Cheryl Dinolfo and Waste Management of New York are reminding residents to recycle cardboard, especially after the holidays.

Cardboard used for shipping has become one of the most disposed of household materials with the increasing popularity of online shopping.

“As households clean out items at the close of the holiday season, it’s important to remember to recycle materials properly,” Dinolfo said. “Every year we continue to see cardboard in our landfills, which could instead be recycled into new products. Proper recycling is good for the economy and the environment.”

Cardboard that is used to protect holiday gifts during shipping often weighs more than the gifts themselves. Almost 20 percent of annual retail purchases are made during the holiday season, resulting in a spike in recyclable materials.

Cardboard can be recycled through curbside recycling pickup or at the Monroe County Ecopark, 10 Avion Drive, Rochester. To recycle curbside, cardboard must be flattened down or cut into small pieces and placed in or under the recycling container. Greeting cards, gift boxes, wrapping paper and wrapping paper tubes can all be placed in recycling bins as well.

The Monroe County Ecopark is open from 1 to 6:30 p.m. Wednesdays and 7:30 a.m. to 1 p.m. Saturdays.
