Hospitals largely get rid of waste by burning it – the tried and trusted resolution. However medical waste ought to be recycled, stated Nepali engineer and social entrepreneur Mahesh Nakarmi, who has campaigned for hospitals within the South Asian nation to repurpose the whole lot from used syringes to sanitary pads and even amputated limbs because the late Nineties.
Essentially the most troublesome factor about recycling hospital waste just isn’t the technical, procedural or monetary obstacles of doing so. It’s the attitudes to waste amongst busy medical doctors and nurses, stated Nakarmi stated, whose concept for a round financial system for hospitals has taken greater than a decade to mattress in to Nepal’s healthcare system. “Waste administration just isn’t about recycling. It’s behaviour change,” he stated.
The medical business generates big quantities of hazardous waste, and contributes to 4 per cent of world carbon emissions – larger than in delivery or aviation. In Nepal, healthcare establishments generate as much as two kilogrammes of waste per hospital mattress, per day.
Nakarmi based the Kathmandu-based non-profit Well being Atmosphere Local weather Motion Basis (HECAF360) within the mid-Nineties, figuring out of a dialysis centre. He had seen that medical waste from the dialysis centre, which included blood and urea, was being combined in with municipal waste, which posed a critical contamination threat to the folks dealing with the waste.
Nakarmi advised to the hospital board that the centre must be closed down till an answer was discovered. “You’re the engineer, so discover a resolution,” he recalled being toutdated by the board.
Most international locations, even now, burn medical waste. However Nakarmi was towards it. “Burning just isn’t a sustainable resolution,” he stated. His concept was to make use of an autoclave, a machine that steam-blasts medical gear to kill dangerous micro organism, to disinfect the waste glass, plastic and metals earlier than sending it to scrap sellers for recycling. Nonetheless, after sourcing a donated autoclave – the primary autoclave in Nepal for use for medical waste – from the USA Company for Worldwide Growth (USAID), Nakarmi was met with resistance from some medical doctors.
“They weren’t proud of me. They stated an autoclave shouldn’t be used for waste, it ought to solely be used for medical gear.”
Nonetheless, after a go to from a World Well being Organisation (WHO) official from the Netherlands in 2007, Nakarmi discovered himself presenting his idea on the WHO headquarters in Geneva. He was inspired to export his resolution past Nepal, and elsewhere in South Asia. However getting traction for his idea has not been simple.
“It took me three years to get one venture off the bottom, as a result of nobody was satisfied it could possibly be finished in Nepal,” he stated. It wasn’t till 2010 that Nakarmi landed a venture, with the Nationwide Hospital of Nepal in Kathmandu. Since then, Nakarmi has been approached by different hospitals across the nation to trial his idea, which he has developed for different kinds of waste.
He has additionally launched anaerobic digesters to transform organic, pathological and meals waste into methane gasoline that could possibly be used as cooking gas. His improvements not solely earn an extra income stream for the hospitals he works with, however assist to lift their profile. “Hospitals that burn their waste face a threat to their popularity,” he stated, pointing to the well being impacts of smouldering medical waste.
On this interview printed forward of World Well being Day, the 2023 Sustainability Management A-Checklist winner talks about why all forms of hospital waste must be recycled and the obstacles blocking the round financial system for healthcare.
Inform us how massive of an issue healthcare waste is in Nepal.
There’s a massive downside with mishandled medical waste resulting in infections. WHO estimates that 300,000 folks die in India because of soiled syringes yearly, as many used syringes discover their manner onto the black market. Internationally, 1.3 million folks die from utilizing soiled needles.

How troublesome has it been to combine your strategies into conventional healthcare methods which might be usually resistant to vary?
It’s actually troublesome to vary behaviour in hospitals. Nurses and medical doctors don’t have the time to handle waste. However it doesn’t take lengthy to chop a used syringe needle, that are manufactured from extremely recyclable stainless-steel. We lined up a gaggle of nurses, gave them a syringe and timed how lengthy it took them to chop the needle utilizing a reducing machine. It took them two seconds. However it did take a coaching programme to vary their mindset and persuade them that it was value their time.
Is there any sort of medical waste that you simply can’t recycle?
Simply 10 to fifteen per cent of the waste we handle is shipped to landfill, the remaining is recycled. The higher hospital employees are at segregating the waste, the much less is shipped to landfill. We attempt to go to sufferers’ bedsides and separate the waste at supply, as a result of whether it is combined it turns into costly to salvage contaminated recyclables.
We’ve got developed a biodigester that may course of pathological waste – physique elements, as an illustration amputated legs and even aborted infants beneath the age of three months. We convert it into cooking gasoline, in the identical manner that meals waste is processed. Meals waste makes up 50 to 60 per cent of the waste we handle in a hospital.
We’ve got additionally been engaged on a programme that includes earthworms consuming dirty bandages and used sanitary pads, changing what they ingest right into a non-toxic residue. However now we have discovered by way of our analysis that menstrual sanitary pads comprise poisonous chemical substances, so can’t be processed [a December study by George Mason University found endocrine-disrupting chemicals that can interfere with human hormones and cause medical issues in sanitary products]. We discovered that the earthworms in our initiatives wouldn’t ingest the sanitary pads due to the poisonous chemical substances in them. This is a matter that nobody is speaking about.
Cotton medical tapes and gauze are compostable, though hospitals not often have the area to do composting.
What’s the most troublesome sort of medical waste to recycle?
The simplest materials to recycle is the more durable plastics. However it’s not a lot the fabric the thing is produced from, it’s amassing sufficient of it to realize scale and storing it, which is troublesome to do in a hospital surroundings.

Who’re the offtakers of the stuff you recycle?
Recycling is in its infancy in Nepal. However we do recycle a few of it regionally. Some is shipped to India. We solely take care of scrap sellers we all know. We present them how we disinfect the fabric within the autoclave and use the system. We ensure that there is no such thing as a blood on the fabric they take. We additionally should watch out that the autoclave doesn’t soften the fabric.
The plastic is hospitals tends to be of top of the range, so there may be at all times demand for it. However one downside is that the producers don’t print the kind of plastic on the facet of things. It will be quite a bit simpler for recyclers in the event that they knew what mixture of plastic merchandise reminiscent of blood baggage have been produced from.
Did you expertise issues in the course of the Covid-19 pandemic to maintain your programmes going, due to the heightened sensitivity round contamination and waste?
No. We used the identical system to handle vaccination waste throughout Covid-19. We’re additionally now engaged on a system to assist drug customers to recycle their used syringes. After they’ve consumed the medication, they bring about again the needle to make use of and we offer them with a brand new one.
What’s your plan sooner or later?
Our mannequin will be deployed anyplace on this planet, and tailored to the native state of affairs. Proper now we’re working with the federal government of Laos and WHO to introduce a system there. We have already got a really nicely already outlined system. Implementing the system just isn’t troublesome. However altering mindsets is essential.
