Circular Healthcare Through a Waste Lens

The UK Circularity Gap Report found that the UK’s circularity rate sits at just 7.5% – meaning over 90% of the materials used in our economy are still drawn from virgin sources rather than being reused.

And healthcare is no exception.

A product is opened, used (or sometimes not used), placed into the bin and then taken away. For most healthcare workers, that’s where the story starts and ends. The patient has been cared for, the item has done its job, and the waste stream takes over.

But should the bin be the end of the story? What if it’s one of the clearest places to see how healthcare products are designed, purchased, used and valued?

That question sits at the heart of circular healthcare, looking beyond disposal to consider the wider system and the full lifecycle: where materials come from, how long products stay useful, whether value can be recovered and why so many healthcare materials still move in a straight line from manufacture to waste.

What Is Circular Healthcare?

Circular healthcare is an approach that aims to keep products, materials and resources in use for as long as safely possible, reducing avoidable waste whilst protecting patient safety, infection prevention and clinical practicality.

The idea of circular healthcare has sounded like a far-off ambition for quite some time – an important and sensible idea, but often just out of reach. Finally, that’s starting to change.

The UK’s Design for Life Roadmap sets out a vision as bold as that of NHS England’s Net Zero ambitions:

“By 2045, the UK will have transitioned away from all avoidable single-use medtech products towards a functioning circular system.”

The important word in this quote isn’t only ‘circular’. It’s avoidable.

There can be no doubt that the healthcare industry will always need specialist products, a prioritisation of infection prevention and carefully controlled waste streams. There are some items that will always require single-use options or specialist disposal because patient safety and clinical practicality must come first.

Adopting circular healthcare doesn’t mean ignoring the realities of the clinical environment, but asking whether single-use has become the default in places where more sustainable alternatives that don’t compromise safety are available.

And healthcare waste has a lot to say on that subject.

Why Circular Healthcare Matters Now

When you consider the meaning of circular healthcare, you realise it isn’t just a case of recycling more. It is, in fact, about keeping products, components and materials at their highest value for as long as possible.

What does it look like in practice? It could mean reducing unnecessary use, extending product life, repairing equipment, reusing products safely and, where appropriate, remanufacturing complex devices or recycling materials into new products where reuse isn’t a viable option. The waste hierarchy is a solid framework to reference in this regard.

We’ve already mentioned the UK’s 92.5% circularity gap, and healthcare is part of that wider material story. It depends on highly controlled products, specialist supply chains and strict safety standards. But it also operates in a world where cost, waste capacity, carbon reduction and supply resilience are under constant pressure.

The Circularity Gap Report groups health and education together as a sector responsible for around 113 million tonnes, or 10%, of the UK’s total material consumption. For healthcare, that reinforces the need for a more strategic approach to procurement, operations and waste management.

How Healthcare Waste Exposes Design Gaps

In most cases, healthcare waste is viewed as the domain of Estates and Facilities or the Waste Manager, with occasional input from Health and Safety or compliance teams. Waste is viewed within the borders of waste contracts and policies, treatment routes, segregation and regulatory requirements, which is essential, but circular healthcare requires us to look further upstream.

Every waste stream reflects decisions made long before an item reaches disposal. It shows what was bought, how it was manufactured and packaged, whether or not it could be used more than once, whether staff had a practical alternative, and whether the system in place made circular behaviour easy, difficult, or impossible.

This shift in thinking is powerful because it turns waste from an endpoint into evidence.

So let’s talk waste forensics 101:

This is why viewing circular healthcare through a waste lens is practical. It provides insight into what happens on wards, in theatres, in dirty utilities, in waste compounds, and in any place where busy clinical staff must make decisions quickly. It reveals whether circularity is practical in those areas, and where the system may currently break down.

Why Waste Intelligence Matters

One of the most exciting opportunities in healthcare waste isn’t just the ability to reduce it, but also to learn from it.

Healthcare waste data can reveal patterns that are otherwise difficult to see:

In a circular system, this is the kind of visibility you need. You can’t retain value without seeing where it’s being lost, and you can’t redesign a system without measuring how it performs. It’s also an important way to give staff the feedback they need to know their actions matter.

This is where the future of healthcare waste management starts to look very different from the past. What was once about moving waste from point A to point B becomes a feedback loop between clinical use, waste generation, procurement, training and sustainability.

The Design for Life roadmap also identifies digital enablement, standards, infrastructure and value-based procurement as areas needing development. Circular healthcare, especially in the realm of medtech, will rely on information as much as materials to be successful – what a product is made from, how it has been used, where it can safely go next and what value can still be recovered.

The most progressive healthcare systems will not simply dispose of waste efficiently; they’ll understand what waste is telling them and use that intelligence to make better lifecycle decisions.

Why the Single-Use Default Is Changing

No one can deny that single-use products have played an important role in modern healthcare, and for the foreseeable future, healthcare will remain dependent on many single-use plastic products.

As Richard Hixson, Founder of CPDMatch, noted in his guest blog, ‘The Hidden Cost of Plastic in Healthcare‘:

“Despite innovations in material science… we must be honest that for the foreseeable future, healthcare will remain dependent on many single-use plastic products.”

The future of circular healthcare isn’t a matter of dismissing that history or any present-day facts, but of recognising when a useful and perhaps convenient model has become overextended. Are we choosing this option just because “we’ve always done it that way”?

The Design for Life roadmap highlights that the NHS throws away around 133,000 tonnes of plastic each year. Also, NHS England’s Clinical Waste Strategy reported 156,000 tonnes of clinical waste disposed of each year in England – equivalent to 34 double-decker buses every day.

Those figures should challenge the assumption that waste is simply the unavoidable by-product of care – some waste is avoidable. Plus, the evidence and impact of reusable alternatives are becoming harder to ignore, with one example being the peer-reviewed study on Sharpsmart reusable containers, published in the BMJ Open.

In the 12 months following conversion to reusable sharps containers, the combined results for 40 acute NHS Trusts included:

The point isn’t that reuse is always the right solution for every circumstance; it’s that single-use should no longer be assumed to be right by default.

How Waste Segregation Supports Circular Healthcare

When thinking about circular healthcare, the conversation often jumps straight to product design and remanufacturing, but there’s a quiet enabler that’s often overlooked and deserves more attention: waste segregation.

After all, if materials aren’t separated correctly, the circular pathways close quickly – regardless of design. Time and again we see recoverable materials entering the wrong healthcare waste streams and items that could be treated through a lower-impact route sent for unnecessary overtreatment.

The NHS Clinical Waste Strategy aims to improve segregation and compliance through its 20-20-60 waste split target:

The strategy also links better waste management to approximately £11 million in annual revenue savings over 10 years and a 30% reduction in CO2e.

This turns waste segregation from being just a compliance exercise into the first operational step towards circular healthcare. With a circular system that depends on thousands of small decisions made correctly each day, healthcare waste management is a discipline built on behaviour, data, safety, and system design.

The Future of Circular Healthcare Is Here

Circular healthcare is no longer a far-off ambition. The pressures driving it are already here:

It’s not a case of forcing circularity where it doesn’t belong, but having the clarity to identify where avoidable waste can be designed out, where products can safely stay in use for longer, and healthcare systems can retain more value from the materials they already depend on.

Circular healthcare has to work for everyone involved, from the theatre team preparing instruments and the clinician providing care to the porter moving waste and the procurement teams balancing cost, quality, safety, and sustainability.

The bin may still look like the end of the story, but increasingly, it’s where the next chapter begins.

Turning Circular Healthcare Into Action

The Design for Life roadmap and the UK Circularity Gap Report both point towards the same conclusion – healthcare needs to rethink the systems, products and behaviours that have made linear models the norm.

Healthcare waste may not always be part of board-level transformation conversations, but it deserves a strategic seat at the table. It has a role to play in safer care, improved sustainability, stronger compliance, and better use of NHS resources.

Sharpsmart’s Shaping the Future of Hospital Waste campaign brings that mindset into the healthcare waste environment. It encourages hospitals to look beyond collection and disposal and consider how waste data, segregation, reusable systems, education, and resource recovery can support a more circular future.
