The new method leaves virtually no carbon emissions and is more sustainable than the current production of the medicine, researchers say.\u00a0<\/strong><\/p>\n\n\n\n

Paracetamol is traditionally made from dwindling supplies of fossil fuels including crude oil.<\/strong><\/p>\n\n\n\n

Thousands of tons of fossil fuels are used annually to power the factories that produce the painkiller, alongside other medicines and chemicals \u2013 making a significant contribution to climate change, experts say.<\/strong><\/p>\n\n\n\n

Tackling pollution <\/h3>\n\n\n\n

The breakthrough addresses the urgent need to recycle a widely used plastic known as polyethylene terephthalate (PET), which ultimately ends up in landfill or polluting oceans.<\/p>\n\n\n\n

The strong, lightweight plastic is used for water bottles and food packaging, and creates more than 350 million tons of waste annually, causing serious environmental damage worldwide. <\/p>\n\n\n\n

PET recycling is possible, but existing processes create products that continue to contribute to plastic pollution worldwide, researchers say.<\/p>\n\n\n

Zero emissions <\/h3>\n\n\n\n

A team of scientists from the University of Edinburgh\u2019s Wallace Lab used genetically reprogrammed E. coli<\/em>, a harmless bacterium, to transform a molecule derived from PET known as terephthalic acid into the active ingredient of paracetamol.<\/p>\n\n\n\n

Researchers used a fermentation process, similar to the one used in brewing beer, to accelerate the conversion from industrial PET waste into paracetamol in less than 24 hours. <\/p>\n\n\n\n

The new technique was carried out at room temperature and created virtually no carbon emissions, proving that paracetamol can be produced sustainably. <\/p>\n\n\n\n

Further development is needed before it can be produced at commercial levels, the team says.<\/p>\n\n\n\n

Some 90 per cent of the product made from reacting terephthalic acid with genetically reprogrammed E. coli <\/em>was paracetamol.\u00a0<\/p>\n\n\n\n

This work demonstrates that PET plastic isn\u2019t just waste or a material destined to become more plastic \u2013 it can be transformed by microorganisms into valuable new products, including those with potential for treating disease.”\u00a0– Professor Stephen Wallace\u00a0UKRI Future Leaders Fellow and Chair of Chemical Biotechnology<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n

World leader<\/h3>\n\n\n\n

The University of Edinburgh is a world leader in engineering biology, which uses engineering principles to harness biological processes to create new products and services. The University hosts the largest and most comprehensive group of researchers in the country. <\/p>\n\n\n\n

Experts say this new approach demonstrates how traditional chemistry can work with engineering biology to create living microbial factories capable of producing sustainable chemicals while also reducing waste, greenhouse gas emissions and reliance on fossil fuels.<\/p>\n\n\n\n

The research, published in Nature Chemistry<\/em>,<\/a> was funded by an EPSRC CASE award and biopharmaceutical company AstraZeneca, supported by Edinburgh Innovations (EI), the University\u2019s commercialisation service.<\/p>\n\n\n\n

\n

We are bringing in exceptional companies like AstraZeneca to work with Stephen and others at the University to translate these cutting-edge discoveries into world-changing innovations.<\/p>\n\n\n\n

Engineering biology offers immense potential to disrupt our reliance on fossil fuels, build a circular economy and create sustainable chemicals and materials, and we would invite potential collaborators to get in touch.\u201d – Ian Hatch\u00a0Head of Consultancy at EI<\/strong>.<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
