Frequently asked questions
Nearly always per unit, but not always in practice. Storage space, spoilage and the temptation to use more of something you already own can wipe out the nominal saving.
If you have to buy containers, shelving or a separate cupboard, spread that cost across the year and enter it. For most bulk staples the figure is small.
Refilling cuts packaging waste substantially, but it only wins on carbon if the bulk product travels efficiently and you actually use it all before it expires.
