Receipts
Every year, an estimated 250 billion paper receipts are offered US customers. Many are automatically printed, declined by customers, and collected for disposal. Concerns have been raised about BPA in thermal paper and some municipalities do not permit thermal paper in recycling streams. What can be done to reduce this annoyance and the waste stream? In some cases, simply changing the store policy to print upon demand will reduce receipt printing by an estimated factor of 30 in campus coffee shops and markets.
