Since 01.01.2016 it has been compulsory for all Austrian businesses to issue receipts for all cash payments. Most receipts are printed on thermal paper using color developers such as bisphenol A (BPA), which pose considerable health and environmental hazards. This study investigates the extent to which the obligation to provide receipts increases the risks to health and the environment. Research has shown that BPA is a possible cause of cardiovascular diseases and can influence the development of microorganisms. Assessments of receipts show BPA concentrations of up to 30,000 mg/kg and the new obligation to provide receipts is expected to increase the use of thermal paper. Though only a moderate increase in the use of thermal paper for receipts is anticipated for Austria as a whole, nevertheless a greater number of people will be affected by the permanent contact with receipts, and recycled receipts can contaminate the new paper products with color developers. Although receipts only account for a small percentage of the paper collected for recycling, due to the high concentration of color developers many studies consider thermal paper to be the main cause of exposure to BPA.
