"I agree with the plastic bag lining the bin, it helps with the smell too.Looking at the main design and a few others, you could put an adjustment toggle (like the ones they use to make tents, gazebos, and crutches) into the back or side supports for different size bags. For factories, the biggest available bag is the best option, but in a residential/office space, we use smaller bags because there is not that much that we throw away.I mean, if you are at the office and you have this bin, but it is too big to fit under the desk so then it has to sit in the walkway. Even with thinner film, support is required from the bottom to ensure that the bag does not rip under the weight of the contents.I think one of the reasons prefer a 'full' bin is that the bag sticking out is unappealing. However, there are places where that aspect is not important. In a light manufacturing environment, where you'd throw offcuts of material, I'd use a material sack instead of a plastic bag because the material sack can hold more weight. Then the owner can sell or give the sack to fashion design schools, and their finished projects can be given to the less fortunate, cycle of life.Yes the bag is unappealing, but if the bin is placed under a desk or in a counter (with the pull out dustbin drawer design you get in kitchens) – everything is hidden from the rest of the world anyway – it does not matter if the bag is visible, but then again why would you want to hide the new bin you just bought, first of its kind, you would want to show it off."
