Method Products’ new 4X Concentrated Laundry Detergent bottle features sustainable packaging material. The 53-ounce bottle contains 100 percent post-consumer recycled PET resin from Amcor Rigid Plastics, making it the industry’s first liquid laundry bottle of its kind, according to the company.

According to Amcor, until now, PET has performed poorly in the liquid laundry detergent market due to compatibility and color stability issues. Amcor provided product compatibility testing with Method’s formula to ensure the package’s integrity on store shelves. Initial testing on preforms and further stability testing revealed no issues, according to Matt Lewis, Senior Development Engineer for Amcor Rigid Plastics.

Director of Packaging Joe Hunter said:

“Among our primary business priorities is reducing the environmental impact of all our products. Analysis using Amcor’s ASSET life-cycle assessment tool showed that by using 100% PCR resin, the package’s life-cycle energy consumption is reduced by 78%, and its carbon footprint is lowered by 35% versus a virgin PET alternative.”
