Some recycled toilet papers do contain BPAs as a result of the type of paper being recycled to make the tissue fibres (e.g. thermal papers and some types of fax and telex paper).
With Who Gives a Crap paper we focus on sourcing high quality raw materials from schools local to our factory, which consist of office paper, books and notebooks - none of which should contain BPAs. We do conduct BPA testing on a regular basis with a third party test agency to assure this is the case.
As each batch is different, we're unable to 100% guarantee that the product is BPA free, however any trace amounts would be in such minuscule quantities that the risk of harm being caused is extremely unlikely.
