Researchers at the University of Edinburgh have developed a method to convert plastic waste into paracetamol — It is the widely-used painkiller also known as acetaminophen.
It is considered to be an enthralling innovation in medical science and environmental sustainability. The significant advancement holds the pledge for greener drug manufacturing and addressing the ever-growing problem of plastic pollution.
From Plastic Bottles to Pain Relief
Traditionally, paracetamol is synthesized using fossil fuel-based chemicals. However, a new study, published in Nature Chemistry, introduces a substitute approach. The scientists used polyethylene terephthalate (PET) — a common plastic found in drink bottles and food packaging — as the starting material.

How It Works:
• PET plastic is broken down through an environmentally friendly chemical process.
• This breakdown provides an intermediate compound.
• The intermediate is then introduced to genetically engineered E. coli bacteria.
• These bacteria then go through the final steps for the production of paracetamol.
It is depicting a mega shift from depending on petroleum-based feedstocks to utilizing everyday plastic waste for producing medicine.
A Natural First: Biocompatible Lossen Rearrangement
One of the most astonishing aspects of the study was the discovery of a Lossen rearrangement — a chemical reaction never before seen in living cells. This reaction played a vital role in converting the plastic-derived compound into paracetamol inside the bacteria.
Why This Matters:
• The reaction was shown to be biocompatible, meaning it occurred without damaging the host cells.
• It bridges a huge gap between biology and chemistry.
• This could pave the way for other complex synthetic reactions to occur within living systems.
A Dual Victory: Medicine and Environmental Cleanup
Professor Stephen Wallace, the lead author of the study, highlighted the huge implications of this work:
“What this technology shows is that by combining chemistry and biology in this way for the first time, we are capable of making paracetamol more sustainably and cleaning up plastic waste from the environment simultaneously.”
Looking Ahead
This breakthrough is more than just a novel scientific method — it’s a trailer of a future where recycling and drug production go hand in hand. Indeed, a lot more research is needed before this can be scaled for industrial use. The idea of turning trash into medicine is not only imaginative — it’s achievable.
In a world burdened by plastic waste and rising environmental concerns, innovations like these bring ray of hope for a cleaner, healthier tomorrow.
