Mastronardi Produce, Kingsville, Ontario, is changing all of its boxes used for shipping and display to bleach-free recycled material as part of the company's Green Grass Project.

Chris Veillon, marketing manager, said the company is constantly looking for ways to reduce its carbon footprint and cut waste in its packaging.

The cartons still allow for bold graphic design, Veillon said, and eliminate the bleaching process in manufacturing.

"There's definitely going to be cost savings," Veillon said.

Veillon said the company began researching cleaner ways of producing its cartons and boxes about a year ago as part of its Green Grass Project. The transition started about two months ago, he said, and should be completed by July.

The Green Grass Project identifies key items in Mastronardi's business process that contribute to an eco-friendly environment and is split into three phases: growing, packaging and distribution, according to a news release.

All of Mastronardi's Sunset brand boxes have The Green Grass Project tag line on the inside panels of the box and highlight the project elements on the underside of the box, according to the release.
