The PL container series was primarily designed for the clever waste collection system in Scandinavia, where precise waste separation and ergonomic design are highly valued. These containers are optimized for both the user and the waste collectors who handle them.

Over the years, innovative lid designs have been developed. For example, the "lid-in-lid" feature allows waste to be disposed of without needing to rotate the container, even when placed backwards. The smaller inner lid has an opposite opening for convenience.

The Flip Lid offers dual benefits: it opens sideways, eliminating the need for reorientation, and it removes the need for the waste collector to close the lid after emptying, reducing strain on the shoulder joints.
