Plastics are a common sight on our planet, found in all corners of the earth, from the Antarctic ice to the deepest ocean trenches. However, a recent study by researchers at the University of Leicester in the UK reveals that brightly colored plastics degrade much faster than others, depending on their color. For instance, red, green and blue plastics fragment more quickly compared to black, white or silver ones due to the colorants that protect them from harmful UV radiation.
The study shows that colors like red, green and blue break down faster than black, white or silver plastic objects left outdoors. This highlights the importance of considering color when designing for durability, recyclability and potential for becoming waste. Plastics designed for outdoor use or heavy sunlight exposure should avoid colors that degrade quickly while short-lived plastics should steer clear of black.
Microplastics present a significant concern as they are part of the food chain and can potentially impact human health by affecting the endocrine system and hormones. Ingesting microplastics has been linked to health issues including cancer and heart disease. Manufacturers must consider the role of color in plastic degradation when designing products and packaging to minimize the environmental impact of microplastics.
In conclusion, brightly colored plastics are not only eye-catching but also more prone to degradation. As such, designers must take into account their choice of colors when creating products with long lifespans and minimal environmental impact.
