37.5 Technology is the only thermoregulating technology to combine natural active particles plus enhanced biodegradation and recycled yarn options. So, you do not need to choose between sustainability and performance. The amount of waste from discarded textiles like clothing and bedding is the highest it’s ever been.
There are very few end-of-life recycling options for textile products. As it can take many centuries for synthetic textiles to biodegrade in a landfill, an enhancing technology is needed to accelerate this natural breakdown cycle and reduce the burden of plastic pollution. Unlike other synthetic yarns that will sit unchanged in landfills for centuries, 37.5 yarns with enhanced biodegradation break down to naturally occurring materials over decades.
Without affecting the comfort and performance of 37.5 Technology, our yarns are now also engineered to biodegrade at enhanced rates when placed in landfills. Third party laboratory testing under ASTM D5511 in an accelerated landfill environment shows almost complete breakdown of the 37.5 staple fiber to natural materials in two years.
Importantly, the additive does not cause 37.5 fibers to simply fracture into smaller pieces (microplastics) that then remain unchanged. The fibers are actually converted at a molecular level to naturally occurring byproducts like those generated by other waste, such as paper or food scraps. Modern, more efficient landfills are increasingly able to capture these gaseous byproducts as a renewable energy source.
