Cotton is a natural fibre that is biodegradable and compostable. Cotton cloth is not a pollutant as it does not produce microplastics like synthetic fabrics. Cotton biodegrades in all natural environments, including soil and water. However, cotton production has a negative impact on the environment due to the use of pesticides, insecticides, toxic dyes, and the large amounts of water and land required. Cotton is also often mixed with synthetic materials in fast fashion, which reduces its biodegradability.

What You'll Learn
Cotton is biodegradable in all natural environments
Cotton is a natural fibre that is biodegradable in all environments. Cotton is grown, not made, and sequesters carbon as it grows. Unlike synthetic materials, which contribute to microfiber pollution and plastic pollution, cotton biodegrades in an environmentally friendly manner. Cotton's biodegradability is important for the health of our planet.
Cotton biodegrades both anaerobically (without oxygen) and aerobically (with oxygen). The speed of degradation depends on the environmental conditions (such as the amount of oxygen, water, temperature, and pH) and the construction of the fabric (such as weight and how tightly the fibres are packed together). In modern landfills, which are anaerobic, cotton will degrade but much more slowly than in aerobic conditions or in a compost heap.
Cotton also has the potential to enhance soil health. Cotton biodegrades into its basic building blocks, which can then be used to create new living things. As cotton biodegrades, it releases essential nutrients back into the soil, enriching the ground below. This process mirrors how fallen leaves decompose in a forest.
However, it is important to note that when cotton is treated with certain chemicals or mixed with synthetic materials, it loses its biodegradability. This is common, especially in fast fashion, where cotton is often mixed with synthetic materials such as polyester, polypropylene, nylon, and polyethylene. These synthetic materials are made from combinations of elements that do not exist in nature and, therefore, cannot be broken down by nature.

Cotton cloth is compostable
Cotton is biodegradable both anaerobically (without oxygen) and aerobically (with oxygen). In modern landfills, cotton will degrade anaerobically, but much more slowly than in aerobic conditions or in a compost heap. Composting cotton textiles can help to divert waste from landfills, reducing the need for synthetic fertilizers and lowering GHG emissions.
Cotton cloth can be composted at home, but it is a lengthy process. It is recommended to reuse cotton items first, for example, by donating them to charity shops or cutting them up for use as cleaning rags. Composting cotton at home requires a compost heap, which is a pile of organic matter built by mixing water, carbon-rich material like dead leaves and twigs, and nitrogen-rich material like grass clippings and food waste. Cotton cloth can be used as carbon-rich material. However, it takes much longer to break down than food waste, so it is recommended only for those with knowledge of composting.
Cotton cloth should not be composted if it is stained with items from the "do not compost" list, such as paint or engine oil. If the compost is to be used for growing vegetables, it is also important to avoid adding cotton cloth that has been extensively dry-cleaned or contains heavy prints, to prevent chemical contamination.

Cotton cloth is a better alternative to polyester
Another advantage of cotton cloth over polyester is its breathability and moisture absorbency. Cotton boasts a much higher moisture absorbency than polyester, making it a suitable fabric for kitchen towels and bath furnishings. On the other hand, polyester is hydrophobic and wicks water droplets, which can make it uncomfortable to wear in hot and humid conditions. Cotton is also generally preferred over polyester, with 9 out of 10 consumers believing cotton is safe for the environment.
While cotton may be more susceptible to mildew and silverfish, it is easier to care for than polyester. Cotton is low-maintenance, quick to dry, and reusable, making it a convenient choice for consumers. Additionally, cotton is a versatile fabric that has been used in a variety of products, including denim, shirts, bedsheets, and towels.
However, it is important to note that conventionally grown cotton has its drawbacks. It requires large amounts of land, energy, and water, and involves harmful chemicals and pesticides that can pollute drinking water and contribute to climate change. To mitigate these issues, consumers can opt for recycled cotton or organic cotton, which are more sustainable alternatives.
In conclusion, while both fabrics have their advantages and disadvantages, cotton cloth is generally a better alternative to polyester due to its biodegradability, breathability, consumer preference, and versatility. By choosing cotton over polyester, consumers can make a more environmentally friendly and sustainable choice.

Cotton cloth production uses harmful chemicals
Cotton is a natural fibre that is biodegradable and compostable. However, the process of cotton cloth production uses harmful chemicals, which can have negative impacts on the environment and human health. Cotton is one of the most widely grown crops in the world and is produced for apparel, textiles, home and hygiene products. As one of the most chemically intensive crops, its production can involve the use of many harmful substances.
Cotton production uses a large number of fertilisers, fungicides, pesticides and insecticides. It is estimated that cotton accounts for 6% of the world's pesticide use and 16% of all insecticide use, more than any other crop. These chemicals can be harmful to the soil, release greenhouse gases and pollute drinking water. Some pesticides, such as Aldicarb and Parathion, are extremely toxic and can cause serious side effects like nausea, vomiting, skin rashes and respiratory problems. The use of GMO cotton, which requires fewer pesticides, has led to a knock-on effect on insect species and biodiversity as other pests have thrived.
The textile manufacturing process involves further chemical treatments. Cotton fabrics are often treated with chemicals to enhance their properties, such as strength and dye absorption. These treatments can include bleaching, mercerizing and sizing. For example, mercerizing uses concentrated caustic alkali to treat plant fibres, making them stronger and more receptive to dye. The use of toxic dyes in cotton clothing can also lead to allergic reactions or endocrine disruption in wearers.
Additionally, around 8000 chemicals are used in textile production, and these can generate pollutants in the form of dust and formaldehyde fumes during the cutting and processing of fabrics. Biocides are also applied to finished garments to prevent mould during transportation and storage. Many of these chemicals are not listed on product labels, making it difficult for consumers to make informed choices about the environmental and health impacts of their purchases.
While organic cotton production aims to address these issues, the conventional production of cotton cloth uses harmful chemicals that can persist in the environment and affect human health.

Cotton cloth production impacts water scarcity
Cotton is a water-intensive crop, requiring approximately 7,000 to 10,000 litres of water to produce just one kilogram of cotton—enough material for a single t-shirt and pair of jeans. This high water consumption has led to water scarcity and negatively impacted ecosystems and local communities.
Cotton farming's high water consumption has contributed to water scarcity, especially in water-stressed regions. With increasing global water scarcity, it is essential to understand the water-intensive nature of cotton agriculture and explore sustainable alternatives. The projected global population growth to 9.7 billion by 2050 will further increase the demand for cotton and other resources, exacerbating water scarcity issues.
The production of cotton has severely impacted water availability for local communities and ecosystems. For example, the Aral Sea in Central Asia lost 85% of its volume due to decades of intensive cotton irrigation. Similarly, the Indus River in Pakistan and the Murray Darling River in Australia have been adversely affected by water diversion and pollution from cotton growing.
Cotton cultivation also degrades soil quality, and the chemicals used in cotton production can pollute drinking water sources. Pesticides and insecticides used in cotton farming can remain in the soil and water for years, infiltrating ecosystems and the food chain. While cotton growers are adopting regenerative agriculture techniques and reducing pesticide and fertilizer applications, the current cotton production methods are still environmentally unsustainable.
To address water scarcity and environmental concerns, alternative fibres that require less water are being explored. Hemp, flax, and bamboo are promising options that produce high-quality fibres with a fraction of the water needed for conventional cotton. These alternative crops have the potential to reduce environmental impacts and build a more sustainable future for the textile and agriculture industries.
