We don't think about it a lot, but part of the cost of buying groceries is also the cost of garbage service. Everybody has to pay for the disposal of their own waste. For most households, it is a minimal cost, and it may even be so minimal that it's rolled into another expense that you don't even see (included with rent, municipal taxes, etc.).
For manufacturing, however, it's a totally different story. Industry produces huge amounts of waste, and often they don't pay to dispose of it properly. The word "giveaway" is exactly right. We are, paying for their cleanup expenses.
