Environmentally friendly PPE in Scots researchers’ sights

“It is crucial that new PPE is made from existing waste streams, be multiuse, re-washable, compostable, recyclable and cheap, thereby reducing their environmental burden and supporting the emergent bioeconomy for new products”

The global use of personal protection equipment (PPE) has skyrocketed due to COVID-19, propelling the industry to revenues of more than £8bn in the UK alone, and although a coronavirus vaccine now seems closer, PPE is likely to remain a part of our everyday lives. However, most PPE materials are single use, contain plastics, are not easily recyclable and end up in our landfills, or worse yet, discarded into the environment.

An innovative research project led by James Hutton Limited, the commercial subsidiary of the James Hutton Institute, will bring together Hutton researchers and industry partners CelluComp Ltd and Halley Stevensons to put a stop to this environmental crisis by developing multiuse, washable, environmentally friendly PPE materials, with funding from Innovate UK, the UK’s innovation agency.

The project will also address additional pressing needs: the development of completely new PPE materials which offer improved safety and comfort by being highly absorbent, breathable and able to actively kill viruses and bacteria.

Dr Andrew Love, a research leader at the James Hutton Institute and principal investigator of the project, explains: “It is estimated that if each person in the UK uses a single disposable mask each day for a year this would result in 66,000 tonnes of contaminated plastic waste, which would be a reservoir of infection, and have ten-fold more of a climate change impact than reusable masks.

“Interestingly, most of current PPE materials are prone to ‘wetting out’ and are poorly absorbent, which raises transmission risks. Likewise, there are very few antiviral PPE technologies readily available in the public domain and those that are suffer from complex manufacturing methods, high expense, poor reusability, poor washability and rapidly lose their antiviral activities.

“It is crucial that new PPE is made from existing waste streams, be multiuse, re-washable, compostable, recyclable and cheap, thereby reducing their environmental burden and supporting the emergent bioeconomy for new products.”

This work builds on the Institute’s existing body of research and patent portfolios with industry partners, while also enabling scientists to identify interesting antiviral and antibacterial properties which will later be investigated to unpick new pathways to control viruses and other pathogens.

Professor Derek Stewart, agri-food business lead at the Institute, commented: “This support from Innovate UK is allowing the consortium to adopt a circular bioeconomy approach to the development of PPE. The science underpinning the PPE, based on sustainable resources, is already showing spectacular viral and bacterial kill efficiencies, and the translation of this into products will be transformative for the health sector.

“The circular bioeconomy, the sustainable, resource-efficient valorisation of biomass in integrated, multi-output production chains, is central to future societal and economic growth, especially within green deal and net zero emissions agendas, and is an increasingly important principle underpinning the work at the James Hutton Institute.”

Innovate UK, as part of UK Research and Innovation, is investing up to £191 million to fund single and collaborative research and development projects through their Sustainable Innovation Fund over the next two years. The aim of these competitions is to help all sectors of the UK rebuild after the effects of COVID-19.

The Sustainable Innovation Fund is funding 1,103 projects, 1189 UK businesses and totalling over £130 million in support across the UK.

Innovate UK Executive Chair Dr Ian Campbell said: “In these difficult times we have seen the best of British business innovation. The pandemic is not just a health emergency but one that impacts society and the economy.

“This project, along with every initiative Innovate UK has supported through the Sustainable Innovation Fund, is an important step forward in driving sustainable economic development.”

The James Hutton Research Institute is the result of the merger in April 2011 of MLURI and SCRI. This merger formed a new powerhouse for research into food, land use, and climate change.
