Adisposable (also calleddisposable product) is a product designed for a single use after which it isrecycled or is disposed assolid waste. The term is also sometimes used for products that may last several months (e.g. disposable air filters) to distinguish from similar products that last indefinitely (e.g. washable air filters). The word "disposables" is not to be confused with the word "consumables", which is widely used in the mechanical world. For example, welders consider welding rods, tips, nozzles, gas, etc. to be "consumables", as they last only a certain amount of time before needing to be replaced. Consumables are needed for a process to take place, such as inks for printing and welding rods for welding, while disposable products are items that can be discarded after they become damaged or are no longer useful.
"Disposable" is anadjective that describes something as non-reusable but is disposed of after use. Many people now use the term as a noun or substantive, i.e. "a disposable" but in reality this is still an adjective as thenoun (product,nappy, etc.) is implied.
The UK government included an enquiry about how best to define "single-use plastics" in its 2018 consultation document on "tackling the plastic problem".[1]: 8
Disposable products are most often made frompaper,plastic,cotton, orpolystyrene foam. Products made fromcomposite materials such aslaminations are difficult to recycle and are more likely to be disposed of at the end of their use. They are typically disposed of using landfills because it is a cheap option. However, in 2004, theEuropean Union passed a law which stopped allowing disposals in landfills.[2]
Many governments[which?] are scaling up their efforts to phase out single-use plastic products and packaging and to manage plasticpackaging waste in an environmentally sound manner.
In 2015 theEuropean Union (EU) adopted adirective requiring a reduction in the consumption of single use plastic bags per person to 90 by 2019 and to 40 by 2025.[3] In April 2019, the EU adopted a further directive banning almost all types of single use plastic, except bottles, from the beginning of the year 2021.[4][5]
In the UK, a 2018HM Treasury consultation on single-use plastic wastetaxation noted that theproduction process for single-use plastic originates in the conversion of naturally occurring substances intopolymers, which vary in their capacity for being re-processed on one or more occasions, meaning that some polymers can be reprocessed and reused only once, and others cannot at present be reprocessed in an economic manner and are therefore destined to have only a single use.[1]: 10 The sale of single-use plastic cutlery, balloon sticks and polystyrene cups and food containers was banned in England from 1 October 2023, following an announcement on "some of the most polluting single-use plastic items" published in January 2023. At the same time, restrictions have been introduced concerning the supply of single-use plastic plates, trays and bowls.[6]
The EU'sSingle-Use Plastic Directive (SUPD, Directive EU 2019/904) went into effect in EU member states on 3 July 2021.
Also in 2021, Australia'sMinderoo Foundation produced a report called the "Plastic Waste Makers Index", which concluded that half of the world's single-useplastic waste is produced by just 20 companies.[7][8] China is the biggest consumer of single-use plastics.[9]
Packages are usually intended for a single use. Thewaste hierarchy calls for minimization of materials. Many packages and materials are suited torecycling, although the actual recycling percentages are relatively low in many regions. For example, in Chile, only 1% of plastic is recycled.[16]Reuse andrepurposing of packaging is increasing, but eventually containers will be recycled, composted, incinerated, or landfilled.
There are manycontainer forms such asboxes,bottles,jars,bags, etc. Materials used include paper, plastics, metals, fabrics, composites, etc.
A number of countries[which?] have adopted legislation to ensure that plastic packaging waste collected from households is sorted, reprocessed, compounded, and reused or recycled. There are also bans on single-use plasticfood packaging in many countries.[17]

In 2002, Taiwan began taking action to reduce the use ofdisposable tableware at institutions and businesses, and to reduce the use ofplastic bags. Yearly, the nation of 17.7 million people was producing 59,000 tons of disposable tableware waste and 105,000 tons of waste plastic bags, and increasing measures have been taken in the years since then to reduce the amount of waste.[18] In 2013 Taiwan'sEnvironmental Protection Administration (EPA) banned outright the use of disposable tableware in the nation's 968 schools, government agencies and hospitals. The ban is expected to eliminate 2,600 metric tons of waste yearly.
In Germany, Austria, and Switzerland, laws banning use of disposable food and drink containers at large-scale events have been enacted.[citation needed] Such a ban has been in place inMunich, Germany, since 1991, applying to all city facilities and events. This includes events of all sizes, including very large ones (Christmas market, Auer-Dult Faire, Oktoberfest andMunich Marathon). For small events of a few hundred people, the city has arranged for a corporation offer rental of crockery and dishwasher equipment. In part through this regulation, Munich reduced the waste generated byOktoberfest, which attracts tens of thousands of people, from 11,000 metric tons in 1990 to 550 tons in 1999.[19]
China produces about 57 billion pairs of single-usechopsticks yearly, of which half are exported. About 45 percent are made from trees – about 3.8 million of them – mainly cotton wood, birch, and spruce, the remainder being made from bamboo. Japan uses about 24 billion pairs of these disposables per year, and globally the use is about 80 billion pairs are thrown away by about 1.4 million people. Reusable chopsticks in restaurants have a lifespan of 130 meals. In Japan, with disposable ones costing about 2 cents and reusable ones costing typically $1.17, the reusables better at the $2.60 breakeven cost. Campaigns in several countries to reduce this waste are beginning to have some effect.[20][21]
Israel is considered the world's largest user of disposables food containers and dinnerware. Each month, 250 million plastic cups and more than 12 million paper cups are used, manufactured and disposed.[22] In Israel there are no laws about manufacturing or importing of food disposable containers.[22]
Akulhar is a traditional handle-lessclay cup fromSouth Asia that is typically unpainted and unglazed, and meant to be disposable.[23] Sincekulhars are made by firing in akiln and are almost never reused, they are inherently sterile and hygienic.[24] Bazaars and food stalls in theIndian subcontinent traditionally served hot beverages, such as tea, inkuhlars, which suffused the beverage with an "earthy aroma" that was often considered appealing.[25]Yoghurt, hot milk with sugar as well as some regional desserts, such askulfi (traditional ice-cream), are also served in kulhars.[26] Kulhars have gradually given way topolystyrene andcoated paper cups, because the latter are lighter to carry in bulk and cheaper.[27][28]
Medical and surgical device manufacturers worldwide produce a multitude of items that are intended for one use only.[29] The primary reason is infection control; when an item is used only once it cannot transmit infectious agents to subsequent patients.[30] Manufacturers of any type of medical device are obliged to abide by numerous standards and regulations. ISO 15223: Medical Devices and EN 980 cite that single use instruments or devices be labelled as such on their packaging with a universally recognized symbol to denote "do not re-use", "single use", or "use only once". This symbol is thenumeral 2, within a circle with a 45° line through it.
Examples of single use medical and hygiene items include:
