That the world is not so reactive to technological evolution, this is demonstrated by the fact that the receipt seems to be still the only way to keep track of a purchase: this when there is digital, which does without thermal paper, polluting, toxic compounds and waste. Yes, because no one has ever paid much attention to the receipt, but this tiny piece of paper that reminds us of having consumed a coffee that day at that time is not recyclable, contains bisphenol A - a hormonal disruptor - and is highly contaminating. This is when there are countless alternative ways that could send the receipt in retirement, for the happiness of the environment, our health and our wallets burst with faded sheets.
The receipt was introduced in different countries to fulfill two tasks: to witness the purchase of a product - useful in case you want to make a return or a change - or as a weapon against tax evasion. In both cases, there are alternative ways that would make the use of the receipt useless, as well as improve its efficiency.
The purchase receipt left by traders is made of thermal paper which, instead of ink, uses heat to make numbers and letters visible. This is possible thanks to the presence of bisphenol A (BPA), a chemical compound considered harmful since the '30s: the categories that are likely to be damaged are the cashiers and cashiers, who come into contact with the bisphenol daily through the skin and respiratory tract. It is a substance called "hormonal disruptor", imputed in diseases of male sexual development in the fetus and in the decline of fertility in adult men.
A research has estimated that in a year only in England they produce 11.2 billion, for a cost of 32 million pounds. It is necessary to consider that almost all the issued receipts are transformed into garbage, while only a small part is kept.
To aggravate the whole, there is the fact that the receipts are not recyclable. They should not be differentiated in paper, because it is not paper. The best way to dispose of them remains the landfill, but this does not prevent the compounds present in the receipts - first of all the bisphenol A - to pollute the environment.
Years later from the introduction of receipts as a strategy to contain tax evasion, we can certainly say that it is not an effective tool. On the contrary, it is something old-fashioned, obsolete, harmful, polluting and non-recyclable
