Scientists have accidentally developed a mutant enzyme capable of breaking down plastic drinks bottles, a significant discovery in the fight against plastic waste. However, its global implementation is expected to take over a decade due to the need for extensive testing and regulatory approval. Currently, the process of recycling with this enzyme may not be cost-effective compared to producing new plastic from oil. The enzyme was derived from a bacterium found in a Japanese waste site, which naturally consumes plastic. While the enzyme itself poses limited risks, concerns exist about potential ecological impacts if it were to spread in the wild, particularly regarding the durability of certain materials. Additionally, countries like Britain are moving towards reducing single-use plastics, highlighting a growing awareness of plastic pollution. Overall, while the enzyme presents a promising avenue for addressing plastic waste, practical and safety considerations must be thoroughly evaluated before widespread application.
