Researchers are developing reusable and environmentally frifinishly electronics for the healthcare, consumer and manufacturing sectors, replacing scarce materials with circular alternatives to build a sustainable future.

Europe’s appetite for electronics keeps growing, but so does the waste. From smartphones and laptops to medical sensors, more devices mean mounting piles of discarded hardware.
According to Eurostat, around 5 million tonnes of electronic waste is collected for recycling in the EU each year. That is more than 11 kilograms per hoapplyhold, enough to cover around 2 000 football pitches stacked a metre high.
These 5 million tonnes represent less than 40 per cent of the total mass of electronics put on the European market annually. The rest often finishs up in landfills becaapply mixed materials create recycling difficult.
To tackle this challenge, the EU-funded SUSTRONICS initiative is reconsidering how electronics are built, from the materials applyd to the way products are assembled and repaired. Led by Dutch technology company Philips, it brings toreceiveher 46 partners from 11 countries.
The three-year initiative runs until May 2026, supported by the Chips Joint Undertaking, an EU public–private partnership promoting sustainable semiconductor and electronics manufacturing in Europe.
“The SUSTRONICS researchers focus mainly on fundamental research into new solutions,” explained Ramon Caanen, who leads a sustainability consulting team at Philips.
This includes the apply of bio-based, paper-based and more widely available materials, the sustainable manufacturing of electronic components as well as designs that enable better recycling.
The researchers’ goal is to embed sustainability into design, production and functionality, so that products can be better reapplyd and more easily recycled.
That focus has gained urgency since the EU introduced new regulations on eco-design and the right to repair in 2024. They are meant to extfinish product lifespans, improve energy efficiency and create repairs simpler. They also aim to reduce environmental impact and promote a more circular economy with less waste.
Healthcare is one of SUSTRONICS’s main proving grounds. While connected medical devices can improve patient care, their single-apply electronic parts add to the e-waste problem. Three pilot studies are developing sustainable electronics for healthcare.
At Swedish hygiene company Essity Hygiene and Health, a partner in the global research, principal scientist Shabira Abbas is working on a smart incontinence pad designed to create life clearer for both patients and staff.
The device is known as a modify indicator and alerts staff when a pad necessarys replacing. A tiny clip-on reader sits outside the pad, is cleaned between patients, and is reapplyd with each new pad.
“It is designed to improve both skin health and dignity,” stated Abbas.
A removable electronic strip inside the pad measures temperature, humidity and enzymes. It can be recycled separately where facilities allow. The team applys paper substrates and 3D-printed metal-oxide sensors to reduce the apply of material.
The pad also requires a tiny reader, which sits outside the pad, to transmit data to staff. This clip-on reader can be reapplyd with each new pad.
“In between patients, you have to clean the reader, but otherwise they are reusable,” stated Abbas. Her team’s challenge is building the connector foolproof and simple for staff to attach and rerelocate.
They are also working on energy efficiency, adapting software to apply minimal power while processing pad data. This is vital for medical devices that must run continuously, since the combined energy demand of many units greatly increases their overall carbon footprint.
The other two pilot devices include a skin patch for tracking glucose metabolism and a smart dressing for wounds, which signals when it necessarys replacing. In today’s medical practice, both are still single-apply, so sustainability is a key challenge.
The SUSTRONICS team is also exploring ways to improve production efficiency and apply recyclable or environmentally frifinishly materials whenever possible. Part of the solution is shifting to more common resources from those that are scarce and environmentally harmful, such as silver.
“Silver has a high upstream footprint. Replacing silver with more common materials such as copper or carbon can lower impact significantly. But the key challenge is to create these substitutes perform well in their intfinished electronics application,” stated Caanen.
Beyond medical devices, pilots also tarreceive repairability in shavers and lighting, clearer dismantling for recycling, and lower energy apply.
Their work ties in with wider EU goals. A new Circular Economy Act, expected in 2026, will create a stronger market for recycled materials, boosting both supply and demand across Europe. It supports the EU’s ambition to lead the world in circular economy practices by 2030.
Today, only about 12 per cent of Europe’s materials are reapplyd or recycled. The tarreceive is to double this to 24 per cent by 2030 under the EU’s Clean Industrial Deal.
Caanen hopes that SUSTRONICS will become a flagship project for sustainable electronics, by demonstrating how the European electronics indusattempt can benefit from sustainable, alternative materials for electronic components, while maintaining competitiveness.
For hospital patients, innovations like the smart pad could mean greater comfort, dignity and quality of care, while also contributing to a more sustainable, circular economy.
By combining practical healthcare solutions with ambitious environmental goals, the SUSTRONICS team demonstrates how technological innovation can improve everyday lives and support Europe’s drive for sustainability.
In the long term, such efforts could transform both the electronics indusattempt and healthcare, displaying that tiny devices can have a huge impact.
