This calculator is not perfect and we know it, but it should give you some ideas on how much waste you are producing each year and encourage you to lower your impact on the environment. You might be missing some items in this calculation, but we will add more items as we go :)
When filling up the calculator think either, how often you purchase such an item, or how often do you trash/get rid of it. If you are not using some items, just leave the row blank.
