You can easily separate plastic from general trash in the Simplehuman Rectangular Liner Pocket 24L + 34L Stainless Steel. The trash can has a plastic inner bucket and a trash bag holder. When you want to throw out some trash and you put your foot on the wide pedal just a little too hard, the stability bar prevents the trash can from tipping over. This keeps the trash can neatly in balance. Full bag? Thanks to the built-in trash bag dispenser at the back of the trash can, you can replace the trash bag without much effort. Take a new bag from the dispenser, fold the bag around the outer edge, and drop the lid. The motion control system ensures that the lid doesn't close with a bang, but closes silently. The Simplehuman trash bag Code H is suitable for use with this trash can.
