As I have already written: the bin liners are a) a bit to small to perfectly fit the bin (the size is the main reason I buy your liners), so sometimes by trying to fit them on the bin they tear (too thin). I am forced to put 2 liners every time I change them (lots of waste, even though they are thought of as green) and even so they often tear if they are too heavy (I have to change them when they are not completely filled to avoid tearing, again a lot of waste). The brabantia bin I have bought (half-moon combining normal and compostable waste is not well designed for compostable waste: a) the compostable side is too long (see above the the liners tear because the do not touch the ground) b) the compostable side is ALWAYS wet, even if the liner does not tear (ventilation is necessary to compostable waste) and I have to clean it every time (the compostable side is very difficult to clean as it is too long and narrow). I advise to change the computable size and sell it separately for those who already own the double bin. I advise to change the compostable liners in size and thickness. Best chewing
