Care/Lifespan: Lifespan of cotton depends on the length of the fiber. Different fiber lengths are utilized for specific products and expectancy of durability. Longer fibers are used to make towels, bandages, and wallpaper while shorter fibers are used for dynamite, photographic film, and rayon. Cotton has many different purposes, so its specific lifespan is ultimately determined by how it is used and how carefully it is cared for.
Decomposition: Cotton can take about five to six months for cotton to fully decompose. Since cotton is a natural fiber it is biodegradable, which helps microorganisms break them down easier.
How Much Goes to Waste: It is inevitable that clothing will end up in landfills due to excess and improper disposal of their unwanted garments. Cotton is an affordable fabric making it a popular fiber choice in fast fashion. Clothing consumer culture motivates fast fashion companies to produce higher output resulting in clothes that aren’t properly disposed of. There are over 16 million tons of textiles that end up in landfills. The average person disposes about 80 pounds of clothing per year. Unfortunately, cotton farming is responsible for 24% of insecticides and 11% of pesticides that contaminate soil and water.
How Companies Are Reducing Waste: Companies like Patagonia are reducing textile waste by repurposing cotton scraps. Ecotec is another company that uses recycled yarn made from pre-dyed cotton which reduces water consumption by 80%. Companies recognize that recycling cotton fiber and regulating water consumption can make an impact if done right. By recycling scraps or reusing cotton, companies can mitigate the amount of textiles that end up in landfills.
Where it is Made: The demand for polyester has been on the rise since the 1990s, placing a high demand on factories, specifically in Asia. According to IHS Markit, “Production of polyester fiber has migrated to Asia, which now accounts for 94% of global capacity.” This isn’t too surprising considering the booming textile industry in Asia and the high demand for polyester in China, which is currently the largest consumer of polyester fabrics based on the most recent available data. In the future, however, some production is expected to move to less-developed countries in Asia, such as Vietnam and Bangladesh, in reaction to rising wages in China. Other big players in the production of polyester include India and Southeast Asia, who continue to pay less for labor.
Lifespan and Care: The durability of polyester fabric means it’s easy to care for and long lasting. Despite its environmental issues, polyester is versatile and usually quite cheap. Experts say it’s also strong, stretch resistant, easy to clean, and doesn’t wrinkle easily.
Decomposition Process: Polyester sticks around for a long time and pollutes the planet. The decomposition process for polyester is long and complicated. Because it’s not biodegradable, it can take anywhere from 20 to 200 years before it’s gone. It’s also comprised of petroleum, which means it pollutes the Earth once it does finally decompose.
Major Environmental Issues:The most pressing sustainability issues brought up by polyester production include: water scarcity, water pollution, oil pollution, and energy consumption. According to CFDA, Polyester production also ends up emitting 14.2 kg of CO2 per kg of polyester produced. In fact, in 2015, polyester ended up emitting 282 billion kg of CO2. It also sheds an estimated half a million tons of microplastics into the water each year.
Environmental Factors in Transportation/Shipping: It’s estimated that it takes about 3 megajoules (MJ) of energy to transport a piece of polyester, using trucks and lots of gasoline. Pipelines, ships, and tankers are also used to help with the transportation of the petroleum that makes up polyester. Pumping stations are also used to vent gases and remove excess fluids.
Lifespan and Care: Not the longest lasting. There’s no doubt that rayon and rayon blends tend to be fairly accessible and inexpensive. However, with this cheap price tag comes a shorter lifespan. According to medium.com, generally, rayon can only last a few seasons of being washed before it starts to pill, stretch, and bag. It also absorbs moisture, which makes it even weaker. Typically, it should be dry cleaned to prevent these side effects, which means its care process can be a little more extensive than other fabrics.
Major Environmental Issues: Rayon generates undesirable water and air emissions and the processing of wood pulp leads to the use of many harsh chemicals that pollute our planet. Of particular concern is the emission of zinc and hydrogen sulfide. Additionally, according to Canopy Planet, “Dissolving-pulp (the base material for rayon/viscose) wastes approximately 70% of the tree and is a chemically intensive manufacturing process.” It is also estimated that 150 million trees are used every single year in the production of cellulosic fabric. Studies from the 1930s show that 30% of American rayon workers suffered severe effects mainly due to the release of carbon disulfide in the process. Fortunately, in the last two decades, new technologies have been deployed in the viscose manufacturing process which are highly efficient in capturing the carbon disulfide released in the manufacturing process. Leading manufacturers of viscose now apply these latest technologies in the viscose process for effective control of hazards from these chemicals.
Environmental Factors in Transportation/Shipping: Rayon generates undesirable water and air emissions in its transportation process as well, since it’s typically shipped overseas. This leads to significant consumption of energy and oil in gasoline.
How Much is Produced: About 40 million tons are produced per year. In the UK, approximately 400 tons of PVC are recycled every month. In terms of plastic, 8.3 billion metric tons have been produced.
How Much Goes to Waste: According to National Geographic, 91% of plastic is wasted, with more than 6.3 billion of the 8.3 billion metric tons produced ending up in landfills. PVC is hard to recycle due to heavy metal additives such as lead and cadmium. For this reason, less than 1% of PVC plastic is actually recycled.
