Sonoco is producing plant-based plastic bottles for Ecover’s new home care line.

Ecover bought Method in 2012 to become the world’s largest green cleaning company.

It has launched its green brand in North America with a new look in Sonoco’s sustainable packaging: extrusion blow-molded bottles made from Plantplastic, Ecover’s proprietary blend of bio-sourced high-density polyethylene (HDPE) and post-consumer recycled (PCR) resin.

The bio-resin, which is produced using plant-based feedstock and recycled resin collected from municipal curbside programs across the U.S., uses up to 90 percent less energy and emits 75 percent less greenhouse gases compared to petroleum-based virgin resin, and is recyclable in most curbside recycling programs, the company says.
