The next generation of biodegradable polymers was introduced to the market in the 1990s and consisted of starch-based products. One of these polyesters was the so-called PCL polymer (poly ε-caprolactone).
Biodegradable fibers produced today are among others the aliphatic polyester [[Ingeo]] ® (poly lactic acid, PLA) and biodegradable fibers (PDO) extracted from corn that are compostable. Compared to the production of traditional [[artificial fiber]] the consumption rate is 20-50% less fossil fuel and results in a lower contribution of greenhouse air emissions. Another positive environmental aspect of this fiber is that fibers raw materials is growing rapidly, in contrast to the traditionally regenerated cellulose derived from spruce wood. [2]
