Has any member found a way to effectively reduce the capacity of a 200ltr bin? I can get the bin 'going' but with only two in the house we do not produce enough waste. The new 100ltr bin would be an option but if I can reduce the capacity of the existing it may work just as well. Was thinking of a OSB board frame to bring the walls in but maintain the air flow at the base. Any thoughts welcome. We are central Scotland so temperatures are not helpful!
