#1 - Reduce
Take digital receipts if offered, if this works for you.
#2 - Dispose
Place all receipts in the trash. Receipts, even though they are paper, are not recyclable as most contain thermal coatings or fillers that render them non-recyclable. Many contain BPA, a chemical associated with adverse health effects at high rates of exposure. BPA may contaminate other paper products being recycled.
