A Scottish college has teamed up with a moulding firm to create medical gear from chewing gum scraped from the streets and outdated fridge elements.
Maiwenn Kersaudy-Kerhoas, a professor in microfluidic engineering at Heriot-Watt College, labored with English moulding firm Nice Central Plastics to develop lateral circulate exams (LFTs) in a challenge geared toward slicing medical waste.
Prof Kersaudy-Kerhoas has produced 5 units produced from Excessive Affect Polystyrenes (HIPs), that are taken from a variety of recycled plastics together with “post-consumer” chewing gum and fridge elements.
It’s estimated that over 4 billion LFTs are manufactured yearly, with round 16,000 tonnes of plastic produced globally annually for them.
The exams verify for a variety of sicknesses together with strep A, pre-eclampsia and Covid.
Prof Kersaudy-Kerhoas stated that, if creating LFTs from sustainable supplies turns into the brand new norm, carbon emissions may be minimize by 30-80%.
She stated: “We’ve now had approval to check these prototypes, ensuring they operate in addition to the prevailing ones, significantly concerning the circulate of liquid on the testing strip.
“In addition to demonstrating feasibility of their sensible software, these new units assist to help a wide-ranging dialogue round healthcare sustainability typically and the way we’d develop a round financial system by means of potential adjustments in procurement and laws.
“Sustainable plastics will not be the one method, there are paper-based options in improvement, however they may take some time to be produced at scale, as producers will want vital funding in new manufacturing traces.
“After rigorous scientific, economical and regulatory investigations, recycled plastics could possibly be used with present gear and a fast win for some merchandise like LFTs.”
Maiwenn and her workforce have been keen about lowering medical waste all through their careers and the figures make it apparent why that is such an pressing challenge

Steve McLaughlin, deputy principal for analysis and influence at Heriot-Watt and the director of well being and care applied sciences, stated: “Our researchers right here at Heriot-Watt College are working arduous to deal with local weather change and discovering new methods to scale back plastic waste and the air pollution it causes is a part of that.
“Maiwenn and her workforce have been keen about lowering medical waste all through their careers and the figures make it apparent why that is such an pressing challenge.
“The mission of the brand new world analysis institute in well being and care applied sciences is to work intently with business and sector companions to ship modern, sustainable and use-inspired options to assist remedy world well being challenges in a spirit of co-creation.
“The work Maiwenn is doing on sustainable LFTs is strictly the kind of challenge we need to help and we’ve the world-leading analysis and engineering capabilities right here at Heriot-Watt to do it.”
Nice Central Plastics, based mostly in Northamptonshire, specialises in utilising recycled plastics.
Kiron Phillips, head of gross sales and advertising on the agency, stated: “We take satisfaction in our sustainable manufacturing processes, and we undertake this ethos throughout all ranges of our enterprise.
“This collaboration highlights our dedication to cutting-edge analysis and improvement.
“By championing sustainable alternate options akin to Gum-tec and Limex, we not solely mitigate environmental influence but additionally pioneer a shift within the business, setting a benchmark for accountable manufacturing practices.”
