Natural cleaning products brand Seventh Generation is using biobased polyethylene produced by Braskem in its 100-oz laundry detergent bottles. The bottles are now 80% recycled high-density polyethylene, 17% biobased polyethylene, and 3% colorant. The biobased portion replaces virgin, petroleum-based polyethylene.
Derrick Lawrence, Seventh Generation Director of Packaging Development, tells Greener Package that incorporating more than 80% post-consumer recycled polyethylene in its larger bottles has been a challenge. “Our 100-ounce laundry bottle was one of our few remaining bottles under 100% and one of our largest contributors in total pounds of virgin petroleum plastics,” he adds. The company is targeting 100% biobased or recycled packaging materials for all its products by 2020. It chose to use Braskem’s biobased polyethylene because a drop-in replacement would minimize manufacturing changes and not contaminate the recycling stream.
