What makes this TPU unique is the presence of bacterial spores embedded in it. Derived from a special strain of Bacillus subtilis, these spores are stimulated by the nutrients in the compost and break down the plastic itself.
TPU is infused with spores that can withstand harsh conditions. When placed in compost, spores germinate and begin to break down the plastic.
It is noteworthy that plastic exhibits a certain level of self-decomposition even without a microbe-rich environment. Scientists write that Bacillus subtilis is a safe bacteria used in probiotics and does not harm humans, animals or even plants.
This study, published in the journal Nature Communications, offers a promising solution to the plastic waste problem. TPU retains its strength and stretchability even when reinforced with sports. Although large-scale production is still in development, researchers are optimistic.
