PFAS-coated clothes that are thrown away will often end up either incinerated or in landfill. Unless incinerated at very high temperatures (>1000oC), fluorinated polymers could release more harmful PFAS during burning. PFAS of environmental concern have also been found in landfill leachate. PFAS is found in treated waste water from industrial and domestic sources and has been found in both rivers and groundwater. Conventional drinking water processes will not remove PFAS.Small quantities of PFAS will be removed during wash and wear of products containing PFAS. This includes fluorinated polymers used on stain-resistant coatings, and non-polymers that remain on clothes after production (Lassen et al. 2015).Non-polymer PFAS can build up in blood protein of animals, and is not always removed quickly. This means that predators eating PFAS-contaminated food will have higher levels in their bloodstream, and concentrations can increase up the food chain. Studies suggest that build up of PFAS is similar to those of other Persistent Organic Pollutants such as DDT.PFAS are estimated to be settling in arctic regions at rates of tens to hundreds of kilograms per year (25-850kg per year), depending on the specific PFAS chemical in question. Certain PFAS are released as gases to the environment and are blown a long way by wind and air currents in the atmosphere,. These gas PFAS will over time degrade to more persistent chemicals like PFOS and PFOA. This may be one reason why PFAS of environmental concern have been found in remote regions such as the Arctic as well as near PFAS production sitesPFAS including PFOS and PFOA have been found in air samples around Europe. The chemicals are found in small quantities, but appear in almost all samples tested. PFAS enters the atmosphere both from factories and the air inside our homes. https://www.ncbi.nlm.nih.gov/pubmed/17554424 Non-polymer PFAS are used in the production of fluorinated polymers. The manufacture of stain-resistant finishes generally releases these PFASs into the environment, both by air and water emissions. They are very hard to remove during water treatment. Workers in textiles factories are some of the population most exposed to these potentially harmful chemicals.

Bisphenols in our receipts

  • Bisphenols, also known as ‘Everywhere Chemicals’, are industrial chemicals often used in receipts and tickets.

  • There is increasing evidence that bisphenols are harming the environment and could be impacting human health by disrupting our hormones.

  • Following the recent ban of bisphenol-A (BPA) from use on receipts in the EU, some retailers have now phased out all bisphenols from their receipts. However, many others are now switching to alternative bisphenols, like bisphenol-S (BPS), which are of similar concern.

  • Legislation enforcing a ban on all bisphenols from use in receipts is now needed to protect both human and environmental health, and to ensure a level playing field for retailers.

What are bisphenols?

Bisphenols are a group of industrial chemicals used in plastics and thermal paper, such as tickets and receipts. Bisphenol-A (BPA) is the most well studied bisphenol and one of the highest produced chemicals, manufactured at a rate of around 2.7 million tonnes each year. Evidence suggest that BPA disrupts endocrine (hormonal) systems in both humans and animal species [1] and is found in the blood and urine of almost every person who has been tested [2]. Whilst some bisphenols have not been studied as closely as BPA, all bisphenols have similar chemical characteristics and are therefore likely to have similarly damaging effects.

Bisphenols can enter our bodies through our skin when touching receipts and tickets. They can also be released into the environment through landfill leachate, paper mill effluent and the breakdown of products containing bisphenols.

What's the solution?

We need legislation banning the use of all bisphenols from receipts.

Fidra have been working with the UK’s major retailers and are delighted to see that many have now committed to removing all bisphenols from receipts, check out our Retailer Tables to see for yourself. But this alone isn’t enough. We want to see all retailers choosing bisphenol-free options. This is where legislation comes in. In order to ensure the protection of both human and environmental health, as well as creating a level playing field amongst retailers, we now need to introduce legislation banning the use of all bisphenols from receipts.

Regulating bisphenols

Growing concerns around the effects of bisphenols has led to increases in regulation across the world. This has been most significant for BPA. BPA has been restricted from various products in countries such as Canada, France and China, and was most recently banned from use in baby products and till receipts in the EU [8].

Currently, our regulatory system addresses every chemical individually. This means that BPA will be researched and regulated separately to other bisphenols, such as BPS, rather than being assessed as a group. This process allows companies to easily switch from one chemical to another when one is banned, referred to as ‘regrettable substitution‘, and is exactly what has occurred following the ban of BPA.

BPS and flourine-9- bisphenol (BHPF) are now being used as common replacements in receipts, and yet have been shown to have similarly concerning chemical properties to BPA. These, along with other bisphenols, may therefore also be banned in the future.

By phasing out all bisphenols, businesses and organisations will therefore be able to stay ahead of legislation, avoid cases of regrettable substitution and ensure protection of both people and the environment.

Dr Anna Watson, Head of Advocacy at CHEM Trust said:

“BPA is well known to have endocrine disrupting properties, and it is worrying that a number of the other bisphenols are also being found to have similar hazardous properties. We need the regulators to phase out groups of chemicals of concern, such as the bisphenols, rather than slowly restricting one chemical at a time, which allows companies to move from one harmful chemical to another. We fully support Fidra’s campaign calling on the industry to end the use of bisphenols in till receipts to protect people and the environment from these hazardous chemicals.”

How can you help?

  • Say ‘No, thank you!’

If you don’t need a receipt please say so! Retailers will soon get the message.

  • Keep your receipts safe

If you need a receipt for expenses or proof of purchase, that is OK!  Keep your tickets and receipts in an envelope to limit the contact with skin.

  • Bin them

We know this might not be what you expect from an environmental charity, but we do not recommend recycling receipts. This help will prevent bisphenols being introduced into recycled paper products, such as toilet roll and printing paper.

The impacts of bisphenols

It is clear from scientific research that bisphenols can have a negative impact on human and environmental health and need to be monitored, regulated and banned where their use is unnecessary. Balabanič et al. (2017) [3] go as far as claiming that “endocrine-disrupting compounds (EDCs) are one of the most critical class of contaminants since they can cause adverse effects in the living organisms due to their interference with the endocrine system.” As a result, many academics and NGOs, Fidra included, would like to see greater action in regard to the regulation and use of bisphenols as a group, not just on one bisphenol chemical, such as BPA, alone.

Health impacts

Research [4] on the impacts of endocrine (hormone) disruptors on biological processes highlight the damage that can be caused to human fertility, formation of genitals and hormone related cancers. Valentino et al. (2015) [5] express that exposure to BPA via tin cans, plastic packaging, till receipts and tickets “must be reduced” due to the results that they found on human health, especially in regard to foetal and neonatal exposure.

Environmental impacts

CHEM Trust’s report, ‘From BPA to BPZ: a toxic soup?‘, explains that BPA is ubiquitous throughout our natural environment and has a wide variety of different impacts on wildlife. These include disruption to the development of Zebrafish larvae and amphibians, as well as altering the sex and reproductive systems of various fish species [6].

In addition, a recent study shows that BPA can build up in green algae. This is known as ‘bioaccumulation’ and refers to a chemical being absorbed by an organism quicker than it can be processed. This study also demonstrated that bisphenols could be transferred from contaminated alga to plankton that eat it, therefore suggesting that it is possible for bisphenols to build up in the food chain [7], which we are of course a part of.

Who has already made the move away from bisphenols?

Many retailers have already committed to removing all bisphenols from their receipts ahead of legislation, as well as turning off automatic printing and offering digital receipts. See who’s doing what in our Retailer Tables, below.

Iain Ferguson, Environment Manager for the Co-op, said: “We believe how we do business really matters, from our work to cut carbon, source sustainably and eradicate hard to recycle plastic, through to bisphenol and phenol-free till receipts – we are committed to ensuring we have a healthy, sustainable natural environment to pass on to future generations.”
