The Microbiome, Textiles, and Unpleasant Odors
The human microbiome—all the microorganisms living on and in our bodies—plays a crucial role in how our clothes develop body odors. When fabric comes into contact with the skin, it influences the microbiome and chemical processes. Interestingly, studies have shown that certain antimicrobial treatments, commonly used in sportswear to reduce odor, can actually promote the growth of odor-causing bacteria. Another study revealed that 29% of respondents wash their clothes primarily to remove odors, while about a third said they would wash less frequently if their clothes stayed fresh longer. This demonstrates that consumers are eager for better solutions to combat unpleasant smells in clothing.
Biomimetic technology, which involves learning from nature to solve problems, could be a great way to keep clothes fresh while reducing the need for washing. By using bacteria like Bacillus, which are activated by moisture and temperature, these microbes can outcompete the odor-causing ones. Essentially, treating clothes with such a spray creates "microbially smart" textiles, where the bacteria or their enzymatic potential shape a healthier, non-odor-producing microbial community. This method offers a more sustainable alternative to chemical treatments like biocides or antibacterial agents for removing odors.
The Fashion Industry's Environmental Impact
The fashion industry faces a major challenge: transitioning to a circular economy. Over the last 20 years, emissions from the life cycle of clothing have risen significantly. It’s estimated that clothing consumption accounts for between 2.4% and 7.6% of global greenhouse gas emissions. Some figures suggest the textile industry contributes roughly 10% of the world’s carbon dioxide emissions, with much of this impact tied to the production and maintenance of clothing.
The Environmental Impact of Washing
Washing clothes less frequently and making them last longer can significantly reduce emissions of microplastics, carbon dioxide, and water usage. With the rise of fast fashion, synthetic fibers have surged in popularity, and today, 52% of the world’s textiles are made of polyester. Each year, approximately half a million tons of plastic microfibers are released into the oceans from washing synthetic clothes. In fact, 35% of all microplastic pollution in the oceans comes from washing synthetic textiles. By washing our clothes less often and treating fabrics more gently, we can significantly reduce this form of pollution.
When it comes to energy and water consumption, the impact per wash is substantial. A single wash of a T-shirt uses an average of 2.4 liters of water and 0.056 kWh of energy. By extending the time between washes, we can save hundreds of liters of water and reduce our carbon footprint. Lowering the washing temperature to 30°C is another simple way to cut energy consumption and CO2 emissions.
Time to Rethink Laundry Habits
Laundry is a major environmental culprit when it comes to energy, water usage, and microplastics. Even with advancements in washing machines and cleaner energy production, our habits remain the biggest factor.
Most of the environmental impact of clothing happens during the production and usage phases. Globally, washing and cleaning routines contribute significantly to this. However, people are often reluctant to change their laundry habits, believing that washing doesn’t affect the environment or that lower temperatures don’t clean as effectively.
For meaningful change, we need not only new technologies but also behavioral shifts. The Swedish Society for Nature Conservation notes that four out of ten garments are discarded because they lose shape or shrink, often due to over-washing. By washing our clothes less frequently and avoiding over-washing, we can extend their lifespan and reduce consumption. High-quality clothing and less frequent washing are two keys to a more sustainable fashion industry.
In Summary
It’s time to rethink how we care for and use our clothes, don’t you think? By adopting more circular habits, using smart products like Textile Mist, and washing less, we can spend less time on laundry and help our clothes last longer. It’s a lifehack for a lifetime!
