The worldwide plastic air pollution disaster and the fallout from the COVID-19 pandemic – the place billions of single-use diagnostic assessments had been discarded – is prompting companies and researchers to develop new and extra sustainable fast diagnostic assessments.
Some corporations have designed biodegradable assessments for flu and COVID-19, whereas researchers are discovering new and artistic methods of constructing assessments out of recycled supplies.
However these improvements largely come from corporations and establishments within the world North. Low- and middle-income international locations, the place plastic air pollution is most extreme and native manufacturing of diagnostics is uncommon, will want an enormous push from buyers and regulatory our bodies to grow to be sustainable, specialists say.
Final month, Dutch firm Okos Diagnostics began promoting what it says is the primary absolutely biodegradable check equipment for COVID-19, Influenza A and B and Respiratory Syncytial Virus, after three years of prototyping and testing numerous supplies and designs.
The check case is fabricated from a plant-based materials ensuing from agricultural discard. The entire check, which is prepared for customers to purchase and swab themselves, is now being bought worldwide for EUR 4.99 (US$ 5.5).
The corporate made it a degree that the check be biodegradable and never simply recycled, in order that it might handle the difficulty of used assessments ending up in landfills, particularly in low- and middle-income international locations, co-founder Sander Julian Brus instructed SciDev.Web.
Okos calculated that its check equipment might biodegrade in 10 to 30 months and is now partnering with the Helix Biogen Institute in Nigeria to check biodegradability in real-world situations.
Whereas environmental considerations won’t have been entrance of thoughts within the early phases of the pandemic, “I feel now’s the correct time,” stated Brus.
“Since we entered an endemic section [of the pandemic], now it’s the correct time to change and for the trade to vary and to ensure that if the subsequent factor breaks out, it may be achieved in another way,” he added.
The waste concern
In a 2022 report, the World Well being Group estimated that over 140 million check kits used all over the world through the first section of the pandemic might have generated as a lot as 2,600 tonnes of waste — most of it plastic.
The United Nations is poised to signal a legally binding settlement to curb plastic air pollution by the top of this yr.
Throughout Sub-Saharan Africa, the place charges of HIV and plenty of different illnesses are increased than elsewhere, self-testing has grow to be a lifeline for folks in recent times. That can also be contributing to air pollution in an space of the world the place applicable waste disposal is lagging, says Collins Odhiambo, portfolio lead on the African Society for Laboratory Medication.
An OECD projection sees world plastic use virtually tripling by 2060 from 2019 ranges and rising greater than sixfold in Sub-Saharan Africa.
“Individuals simply throw waste anyplace. Whether it is collected, it’s simply taken someplace and dumped,” Odhiambo, who is predicated in Kenya, instructed SciDev.Web.
Producing extra sustainable supplies as a substitute of plastic might be a part of the answer, however Odhiambo isn’t satisfied that the continent’s manufacturing sector can at the moment help such a shift.
“I feel the panorama in Africa for native manufacturing isn’t but there,” he defined. Neither for sustainable diagnostics, nor for plastic diagnostics.
Most diagnostic or pharmaceutical merchandise attain Africa through expertise switch from wealthy international locations.
We have to first change the observe up [in the global North], in order that in the event that they use sustainable supplies within the North, then once they do the expertise switch to Africa it’s really expertise that features using biodegradable materials.”

Chewing gum and fridge components
Apart from Netherlands-based Okos, an increasing number of corporations and analysis establishments are beginning to take up the problem. British diagnostic firm Abingdon Well being not too long ago partnered with London-based sustainable design consultancy Morrama to provide you with plant fibre check instances for numerous kinds of fast testing. The check needs to be launched in the marketplace by the spring of 2025.
At Heriot-Watt College in Scotland, a bunch of researchers earlier this yr designed assessments fabricated from recycled supplies, utilizing pellets that originated from objects as various as chewing gum and previous fridge components.
“It’s not written anyplace that it needs to be in virgin plastic,” stated Maïwenn Kersaudy-Kerhoas, professor in microfluidic engineering within the College of Engineering and Bodily Sciences at Heriot-Watt College, who has been main the check prototyping.
Nevertheless, utilizing recycled supplies is simply an intermediate answer and in the long term extra funding is required in manufacturing traces for non-plastic supplies, Kersaudy-Kerhoas instructed SciDev.Web.
Elijah Kolawole Oladipo, director of science at Helix Biogen Institute, is optimistic that sustainable diagnostics manufacturing can come to Africa quickly sufficient, if ample funding will be attracted.
The Nigerian analysis institute is partnering with test-makers Okos on a examine to verify biodegradability of check kits in soil. The thought is finally to copy the check’s manufacturing domestically and make it obtainable in Nigeria and past.
As a substitute of continuous to just accept transfers of expertise coming from the worldwide North, Oladipo believes, African nations ought to leverage their abundance of uncooked supplies to construct native manufacturing crops for sustainable merchandise.
