Bella-Dura ™ FABRICS From an Environmental Perspective, Bella-Dura™ is the leading environmentally responsible fabric option in the marketplace. In fact, you could call it the environmental champion of all synthetic fibers. It is the only fiber on the market, synthetic or natural, that begins as a by-product of post-industrial waste and ends its life as a fully recyclable product. Bella-Dura requires substantially less energy to manufacture, uses only a small amount of water during its manufacturing process and produces no harmful industrial waste. Using innovative, engineered, proprietary yarn technology, Bella-Dura yarn is made of a by-product from the petroleum refining process, thus reducing the need for virgin material. The very processing of Bella-Dura salvages a by-product that would otherwise be incinerated, preventing further environmental contamination.
