Rolls of trash-bag liners coming undone, bundles piled up at the back of the cabinet, refills that you can never locate when the bin is overflowing… Many kitchens know this little chaos. We sometimes end up buying more bags even though some are left, simply because they were poorly stored.
Yet there exists a simple, almost free trick that transforms an empty plastic bottle into a practical and compact trash-bag dispenser. This small DIY relies on a straightforward idea: use the bottle’s elongated shape as the housing, with a slot to dispense the bags one by one. The key move is very easy to perform.
A trash-bag dispenser made from a simple plastic bottle
For this DIY, you simply need a clean water or soda bottle, a marker, a ruler, a craft knife, masking tape, and strong double-sided tape. A one-liter bottle is sufficient for a standard trash-bag roll, whereas a two-liter size works better for large 50- or 100-liter bags. The thicker the plastic of the bottle, the sturdier the dispenser will be.
Start by drawing, with the ruler, a narrow rectangle along the length on the side of the bottle. This opening should be a little wider than the roll’s thickness so that the bag slides out without resistance. Then carefully cut this rectangle with the cutter, and remove the bottom of the bottle to be able to insert the roll. The cut edges can be sharp, so it is important to cover them entirely with masking tape to secure the object and prevent the bags from tearing.
Adapting the plastic bottle to your trash bags and your kitchen
Once the bottle is prepared, slide the bag roll inside, making sure to pull the first bag out through the slot. A generous piece of double-sided tape adheres to the filled part of the bottle, just above the opening. It is this area that will bear the traction each time you change a bag. The dispenser sticks very well to the door of a cabinet, the wall of a under-sink cabinet, or the side of a kitchen cabinet for a clearly tidier under-sink storage.
To make the system last, it’s best to pull the bag gently, guiding it with the other hand, rather than giving a strong jerk that could tear the double-sided tape. You can also customize this mini trash-bag storage: spray paint (outdoors, for ventilation), decorative adhesive, or a simple label indicating the bag capacity. A larger bottle will suit bigger rolls, a smaller one for bathroom bags; in a garage, mounted near the workbench, it becomes a dispenser of bags for dirty jobs.
A storage tip for trash bags that reduces plastic waste
Experts explain that most plastic waste today is processed by mechanical recycling, involving sorting, washing, grinding, and then transforming into pellets. When the quality of these pellets is average, they are often used to manufacture products like trash bags, in an open-loop recycling logic. The same studies also remind that a bottle cannot be mechanically recycled indefinitely, the material degrading after a limited number of cycles, around seven.
By giving a second life to a simple bottle, this homemade dispenser thus postpones a little the moment when it becomes waste to be processed. The idea can be extended at will: several bottles side by side, each labeled according to the type of bag, one model in the kitchen, another in the bathroom or laundry room. This little system, installed in just a few minutes, brings order to the home while fitting into an easy-to-adopt daily reuse approach.
