Research: The Biodegradability of Fabrics
Abstract:
Textile waste is a major environmental concern, especially with the rise of fast fashion. Many clothes are made from synthetic fabrics that do not break down easily. This project aimed to investigate how different types of fabric decompose in a composting environment and to determine which materials contribute more to landfill waste. The fabrics chosen were commonly found in everyday clothing, making the research applicable to real-world concerns. The experiment was conducted over a simulated 30-week period. A compost bin was set up with controlled moisture conditions. Six 1-inch by 1-inch fabric samples were used: 100% cotton, denim (mostly cotton), polyester, 50/50 cotton-polyester blend, nylon, and fleece. Weekly visual observations were made, and fabric changes were noted to track decomposition over time. By the end of the 12 weeks, the cotton sample had broken down significantly, shrinking to about 0.3 inches with frayed, discolored edges. Denim also showed visible breakdown, reducing in size and separating at the seams. The 50/50 cotton-poly blend showed moderate decomposition, with the cotton fibers thinning out while the polyester remained intact. In contrast, polyester, nylon, and fleece showed almost no visible change and remained close to their original size (about 1 inch). These results support existing research that natural fibers decompose faster than synthetic ones, which are more resistant to composting. This study suggests that synthetic fabrics contribute more to long-term textile waste. Promoting the use of compostable fabrics may reduce landfill buildup and encourage sustainable fashion practices.

Using technology to increase access to youth mental health support may offer a practical way for young people-to reach guidance, safe-spaces, and early help without feeling overwhelmed by traditional systems. Digital platforms, helplines, and apps could give them a chance to seek support privately, connect with trained listeners-orexplore resources that might ease their emotional load. This gentle shift toward tech-based support may encourage youth to open-up at their own pace, especially when in-person help feels too heavy to approach.
There is always a chance that these tools-quietly make support feel closer than before, creating moments where help appears just a tap away. Even a small digital interaction might bring a sense of comfort. And somewhere in that space, you might…

Great insights here! While reading, I was reminded of our recent office upgrade where we had multiple old copiers to dispose of. After searching, I found a reliable Copier Scrap Buyer in UAE who handled everything from collection to recycling. The process was smooth, transparent, and eco-conscious. It really saved us time and effort. Perfect for companies planning to recycle large machines without hassle.
