In New York, USA, in 1952
George S. James patented a 'sanitary waste disposal bin'. Original Cannon bins were blue in colour, and in 2018 could still be found in some public bathrooms in Scotland. Other companies joined the industry, with PHS and
Rentokil offering a 'sanitary unit exchange', where new bins were supplied and the used ones removed, emptied, washed and returned to another location. Anecdotally, PHS became involved in the industry due to the suggestion made by one of the company secretaries to its owners Alfred and George Tack. In the United Kingdom in the 1970s, there was expansion in the use of menstrual products, but still an absence of disposal options, especially in public places. The
Women's Environment Network (WEN) raised this as an issue arguing that the huge amounts of waste created additional landfill, as well as air pollution through incineration, challenges to plumbing and water pollution. A further innovation in sanitary bins came as a response to research commissioned by Rentokil in the United Kingdom in 1980, which stated that over 70% of used menstrual products also had traces of feces and bacteria. This led to the treatment of sanitary bins with bactericides as part of the re-sanitation process throughout the 1980s. New legislation in the UK in the 1990s meant that employers had a responsibility to provide safe methods for disposal. This meant that by the mid-1990s sanitary bins were common in toilets. In the 2010s, there was a trend for more aesthetic sanitary bins in the UK: Canon Hygiene introduced cylindrical wall-mounted bins; Initial introduced brightly coloured bins. Innovations also included bins with a no-touch sensor, where the 'modesty flap' (the lid) opens automatically. == Fabrication ==
