New Breakthrough in Plastic Recycling and Drug Manufacturing

Recent research has shown promising advancements in addressing two of the most pressing issues facing our planet today: plastic pollution and the reliance on fossil fuels in drug production. Scientists at the University of Edinburgh have successfully utilized Escherichia coli bacteria to convert molecules from common PET plastic into the popular painkiller acetaminophen, also known as paracetamol.

Acetaminophen, like many pharmaceuticals, is predominantly derived from fossil fuels. The innovative approach of substituting traditional ingredients with waste materials such as plastic presents a unique solution to two major environmental challenges.

The process involves chemically breaking down PET bottles, feeding the resulting molecules to engineered E. coli bacteria, which use phosphate as a catalyst to convert the molecules into an organic compound containing nitrogen, ultimately resulting in acetaminophen.

One of the key advantages of this method is its rapid completion within 24 hours in a compact laboratory setup, operating at room temperature without the need for excessive heating or cooling. Furthermore, the team has achieved an impressive 92% yield efficiency.

This groundbreaking approach adapts the well-established Lossen rearrangement chemical reaction for biocompatibility within living cells and bacteria, offering potential applications beyond PET plastic recycling.

The researchers highlight the possibility of extending this method to other plastic types and bacteria, presenting opportunities for more sustainable recycling and drug production practices. This innovative fusion of natural and synthetic chemistry exemplifies the potential for addressing environmental challenges through innovative solutions.

The study, published in Nature Chemistry, underscores the role of synthetic organic chemistry in sustainable chemical synthesis from renewable sources.
