Sanitary bin

Sanitary bin is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sanitary bin rather than just read about it. In short: A sanitary bin is a small receptacle for used menstrual hygiene products that is usually installed in toilet cubicles in many countries of the world. In New York, USA, in 1952 George S.

Key takeaways

  • Sanitary bin belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sanitary bin to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sanitary bin from memory before moving on to harder problems.

Reference excerpt

A sanitary bin is a small receptacle for used menstrual hygiene products that is usually installed in toilet cubicles in many countries of the world. In New York, USA, in 1952 George S. James patented a 'sanitary waste disposal bin'. In the United Kingdom in 1955, Cannon Hygiene were the first waste management company to supply sanitary bins.

Background

Disposable menstrual products were an invention in the early twentieth century, but initially there were no specialist waste receptacles to contain them. Some public toilets contained small cremators, which incinerated the waste products, but more often there was no provision. This meant that most people had to flush, hide or carry these products out of the toilets themselves. One early provider of incinerators in the UK was Southalls' Sanitary Requisites, who were advertising the devices in 1916. The largest manufacturer of incinerators in the UK in the mid-twentieth century was Wandsworth Electrical Manufacturing Company; these were given the soubriquet 'bunnie incinerators'. However they were not common, and women were more likely to flush or hide used products. The issue of hiding menstrual products was noticeable during the Second World War in England, and the Medical Women's Federation (MWF) established a 'Menstruation Leaflet Committee' to spread information to counter the issue. The MWF suggested the process that is recognizable to many today – that each cubicle contains a paper bag for used menstrual products, and a bin for them to be put in.

Early use and development

In New York, USA, in 1952 George S. James patented a 'sanitary waste disposal bin'. In 1955, Cannon Hygiene (Citron Hygiene) were the first waste management company to supply sanitary bins, especially as the number of women in the workforce was growing in post-war Britain. 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 In the UK most sanitary bins are constructed from acrylonitrile butadiene styrene, which is a recyclable plastic. They generally have a capacity of 23 litres and have 460 mm × 425 mm × 200 mm (18.1 in × 16.7 in × 7.9 in). In 2010, Woman's Hour host Emma Barnett drew attention to the poor design of some women's toilets, which often have very little space for sanitary bins, or the containers are added as an afterthought.

Inclusion

In the UK, the campaign 'Boys Need Bins' led by Prostate Cancer UK has been drawing attention to the need for sanitary bins to be placed in male toilets. In Japan, they are not often installed in men's restrooms, but there are requests from men who use incontinence pads, and there is a movement to install them. In 2024, the Football Association launched an investigation as to why sanitary bins weren't available in all the women's toilets at the FA Cup Final.

Some sanitary bins feature Braille on the lids, a feature designed to better enable visually-impaired people using the receptacles.

Art Artist Judy Chicago was one the first to engage with sanitary bins as part of her practice; her installation Menstruation Bathroom (part of Womanhouse) featured bins overflowing with menstrual products. In the 2000s, artist and zinester Chella Quint, placed educational zines into the paper bags provided in toilets for used menstrual products.

Anti-terrorism

Due to increased security measures for the G20 Osaka Summit in 2019, coin lockers and trash cans in stations around Tokyo and Osaka were closed, including sanitary bins in women's restrooms. These were removed from stations on Seibu Railway by the Tokyo Metropolitan Bureau of Transportation. There was a backlash on their removal, which railway managers and security experts did not anticipate, due to the fact that no alternative solutions were considered for what to do with used sanitary products. Sanitary bins were even removed in Tokyo, which is 450 km (280 mi) away from Osaka.

Worked examples

Example 1 — a first encounter with Sanitary bin

Start with the simplest possible case. Write down what Sanitary bin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sanitary bin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sanitary bin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sanitary bin

In research
Sanitary bin appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sanitary bin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sanitary bin is common in secondary-school and first-year university syllabi. It links to neighbouring topics Feminine hygiene, Menstrual cycle, Waste management, so understanding it makes those chapters shorter.
In everyday life
Look for Sanitary bin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
