When food breaks down it releases gases, which can have unpleasant smells, particularly when there is low oxygen in your FOGO bin. You can add more air flow to your by adding carbon-rich ‘dry’ ingredients such as dry grass clippings, dry leaves, straw, or paper. By bagging or wrapping your food in our paper bags, you are adding more carbon-rich materials to the bin, which helps balance out the odours.
