Researchers have produced paracetamol from plastic waste. For example. However, according to a study
Chemists have managed to synthesize paracetamol from plastic waste thanks to a reaction involving E. Moreover, coli bacteria, according to a study published Monday, June 23, whose large -scale involvement remains very uncertain.

This experience “shows that it is possible to produce this essential medication from plastic waste. Similarly. via a process that researchers have produced paracetamol plastic new could not work from a only chemical or only biological synthesis”summarizes this study published in researchers have produced paracetamol plastic the scientific journal Nature Chemistry and produced by researchers from the Scottish University of Edinburgh.
Paracetamol, used against pain and fever, is one of the most common drugs. It is produced based on petroleum derivatives. most often by subcontractors based in Asia, via very inexpensive but quite polluting techniques.
The study authors, funded, among other things by the Astrazeneca pharmaceutical laboratory, proceeded in several stages. They first used components of a used PET plastic bottle (Ethylene polyterephtaplate) to induce a chemical reaction in a. strain of Escherichia coli (E. coli) bacteria.
At the end of this first step, bacteria synthesized a molecule, called “paba”. Then, by genetically modifying bacteria, scientists allowed them to transform this molecule into paracetamol.
The authors argue that this experience opens the way to new techniques researchers have produced paracetamol plastic new to recycle plastic waste. The fact remains that the large -scale application is not easy.
He’s staying “Several practical considerations“To researchers have produced paracetamol plastic be resolved to go beyond the only” feasibility demonstration. “made by this study. write several researchers who have not participated in the study in a comment, also published by Nature Chemistry.
They point out that the initial reaction produces only a limited amount of PABA molecules. which “may not be enough for industrial applications“. But the experience is promising ““, they admit, emphasizing the interest of studying processes that mix biology and artificial chemical reactions.
The study has nevertheless aroused skepticism in environmental defense organizations. “For years. he has never spent a few months without having a new +plastic +bacteria +”quipped Melissa Valliant from the NGO. Beyond Plastic. “These discoveries never reach a sufficient scale to cope with the major problem of plastic pollution”.
