Hospitals' Plastic Waste: A Health Hazard?

Hospitals produce an enormous amount of plastic waste each year. While hospitals have been champions of recycling for decades, their efforts have largely focused on food services and administrative areas rather than patient care settings, where most healthcare plastic materials are generated. The COVID-19 pandemic has also led to an increase in the use of single-use plastics in hospitals. Single-use plastic is convenient for hospitals as it is cheap, durable, and easily thrown out, but it is now facing more scrutiny than ever before.

Plastic waste in hospitals increased due to COVID-19

Hospitals produce a significant amount of plastic waste, with an estimated 25% of all hospital waste being plastic. Single-use plastic is often used in hospitals as it is cost-effective, durable, and easy to dispose of. Some commonly used plastic items in hospitals include syringes, intravenous bags, catheters, test kits, gloves, and personal protective equipment (PPE).

The COVID-19 pandemic led to a sharp increase in plastic waste generation in hospitals. The need for PPE increased significantly during the pandemic, causing shortages and, ultimately, more waste. The World Health Organization (WHO) estimated a 40% increase in disposable PPE production during the pandemic, most of which likely ended up as waste. This sudden excessive plastic waste generation presented a challenge to waste management systems, with waste treatment facilities struggling to keep up despite operating at full capacity.

The increase in medical waste during the pandemic was not limited to plastic waste. The amount of medical or hospital waste, in general, increased sharply, requiring improved medical waste management practices. The pandemic also affected waste generation patterns, with fluctuations in the generation of plastic, food, and medical waste. However, the impact of COVID-19 on waste generation is complex and may vary across different regions and jurisdictions.

The environmental impact of the increased medical waste during the pandemic is a pressing issue, particularly as much of this waste is routinely incinerated, releasing toxic chemicals. To address the plastic waste challenge, hospitals are increasingly focusing on recycling practices and exploring ways to reduce their plastic waste. Some hospitals have successfully reduced plastic waste by training employees on the proper use of disposable items, such as plastic gloves. Additionally, technological advancements and innovations could help reduce the reliance on single-use plastics in hospitals.

Overall, the COVID-19 pandemic exacerbated the plastic waste problem in hospitals, highlighting the need for sustainable practices and waste management solutions in the healthcare industry.

Hospitals are unable to recycle most plastic waste

Hospitals produce tons of plastic waste annually, and a significant portion of this waste is not recycled. The healthcare industry is one of the largest waste-producing sectors, and plastic is a significant component of this waste. While plastic has revolutionized the medical industry, its proper disposal and recycling remain a challenge.

A study found that hospital patients in the United States generate about 33.8 pounds of waste per day, resulting in about 6 million tons of waste annually. Of the 14,000 tons of waste generated daily in US healthcare facilities, about 20-25% is plastic. However, a staggering 91% of plastics, including those used in healthcare, are not recycled and end up in landfills or natural environments. This contributes to the growing problem of plastic pollution, with plastic fragments comprising 50-80% of shoreline debris.

The disposal of plastic waste in hospitals is a complex issue. Healthcare waste is segregated into domestic waste and infectious waste, with clinical waste, such as gloves, bandages, and aprons, requiring expensive treatment and disposal methods. The challenge of recycling plastic waste in hospitals is further exacerbated by the lack of efficient medical recycling systems and the need for proper coordination between the healthcare sector and the recycling industry. Additionally, the recycling of medical plastics is limited due to the difficulties involved in sorting and cleaning, with hospitals often lacking adequate recycling facilities and staff knowledge about recycling practices.

The COVID-19 pandemic has also impacted the use of single-use plastics in hospitals, with increased infection control procedures resulting in a higher demand for disposable PPE and other medical supplies. While some hospitals have implemented initiatives to reduce plastic waste, such as the NHS's "For a Greener NHS" campaign, the healthcare industry's reliance on plastic poses significant challenges to recycling efforts.

Furthermore, the environmental impact of plastic waste in hospitals extends beyond waste volume. The burning of plastic waste releases toxic pollutants, contributing to air pollution and adverse health effects. Additionally, plastic waste can break down into microplastics, which have unknown health consequences when ingested. The healthcare industry's contribution to plastic waste and its inability to recycle most of it highlight the urgent need for sustainable alternatives and improved waste management practices.

Plastic waste is incinerated or sent to landfills

Hospitals produce a significant amount of plastic waste, with single-use plastics making up a large proportion of this waste. While hospitals have been leaders in recycling, their efforts have primarily focused on food services and administrative areas rather than patient care settings, where most healthcare plastic materials are generated. As a result, much of the plastic waste ends up being incinerated or sent to landfills.

Incineration, or burning, of plastic waste is a common method of disposal, especially in the United States, where six times more plastic waste is burned than recycled. While incineration can generate electricity, it also has several drawbacks. For instance, burning plastic can release toxic chemicals, such as heavy metals, and contribute to air pollution and greenhouse gas emissions, specifically carbon dioxide (CO2), a major driver of climate change. The incineration process itself requires a significant amount of energy, and the resulting ash must be managed and disposed of as hazardous waste.

Landfills are another method of disposing of plastic waste. While plastics in landfills do not break down and emit greenhouse gases, they can leach chemicals such as additives and plasticizer compounds if not properly managed. The stability of plastics in landfills means that they do not contribute to global warming in the same way as incineration, but modern incinerators are said to have mitigated the issue of harmful dioxin leaks.

The choice between incineration and landfill for plastic waste disposal depends on various factors, including environmental, health, and economic considerations. Recycling is, of course, the preferred option, but it is not always feasible due to contamination, processing costs, and a lack of efficient recycling systems, particularly in the medical industry. As a result, hospitals often have no choice but to send their plastic waste to landfills or incinerators.

However, there are efforts to reduce and recycle plastic waste in hospitals. Some hospitals are implementing sustainability offices and initiatives to address their plastic waste challenge. Additionally, organisations like Practice Greenhealth work to make hospitals more sustainable by providing resources and guidance on reducing plastic waste and implementing recycling practices in patient care settings.

Hospitals can reduce plastic waste with small changes

Hospitals produce tonnes of plastic waste annually, with the NHS alone creating 133,000 tonnes of plastic waste every year. The COVID-19 pandemic has also led to an increase in the use of single-use plastics in hospitals, such as masks, gloves, and other PPE supplies. However, hospitals can take small steps to reduce their plastic waste and make a significant environmental impact.

One way hospitals can reduce plastic waste is by investing in innovative technology. For example, by switching from traditional contact thermometers, which require disposable plastic probe covers, to non-contact thermometers, hospitals can eliminate the need for millions of plastic probe covers every year. Additionally, hospitals can work together to pressure manufacturers to reduce excessive packaging. Frontline providers suggest that the cardboard and plastic packaging, as well as the supplies themselves, could be recycled to a greater extent.

Hospitals can also focus on reducing plastic waste in patient care settings, where most healthcare plastic materials are generated. HospiCycle, for instance, is a guide that helps hospitals integrate recycling practices into patient care settings and navigate the economic and infrastructure challenges that come with it. By implementing robust recycling programs and studying incoming materials to reduce both inputs and outputs, hospitals can significantly reduce their total waste costs.

Furthermore, hospitals can reduce plastic waste by reusing certain items and being mindful of their usage. For example, Great Ormond Street Hospital in London reduced its use of plastic gloves by reminding staff that non-surgical gloves should not be used for certain tasks. This simple change resulted in a reduction of 21 tonnes of plastic and significant cost savings. Similarly, hospitals can reuse certain single-use equipment, such as plastic surgical devices, by sterilizing and recycling them with discretion.

By making small changes, such as investing in innovative technology, reducing packaging, implementing recycling programs, and reusing certain items, hospitals can play a crucial role in reducing their plastic waste and contributing to a greener healthcare system.

Environmental impact of plastic waste in hospitals

Hospitals produce tons of plastic waste annually, and the environmental impact of this waste is significant. While hospitals have been champions of recycling for decades, most of their efforts have focused on food services and administrative areas rather than patient care settings, where the majority of healthcare plastic materials are generated. The COVID-19 pandemic has also contributed to the problem, with hospitals increasing their use of single-use plastic masks, gloves, and other PPE supplies to control infections.

The medical industry is an area where individual consumers have little say, and it can be challenging to cut down on plastic usage when specific plastics are essential life-saving tools. For example, plastic retractors used to hold surgical cuts open are single-use and must be discarded after each patient. Additionally, manufacturers may label products as single-use to avoid liability, even if the product can be sterilized and reused.

The environmental impact of plastic waste in hospitals is not limited to the amount of waste produced but also includes the toxic chemicals released during incineration. Polyvinyl chloride (PVC) plastics, when incinerated, can release toxic chemicals. Hospitals often have no choice but to incinerate or landfill their plastic waste, as recycling programs are challenging to implement for medical waste.

However, there are initiatives and organizations working to reduce the environmental impact of plastic waste in hospitals. Practice Greenhealth, a non-profit dedicated to making hospitals more sustainable, estimates that 25% of hospital waste is plastic and provides tools and resources to reduce waste and improve recycling. The Healthcare Plastics Recycling Council (HPRC) has developed a guide to help hospitals integrate recycling practices into patient care settings and navigate the economic and infrastructure challenges of recycling healthcare plastics. The NHS in the UK has also launched the "For a Greener NHS" campaign, which aims to reduce the healthcare system's carbon footprint and plastic waste production.

Hospitals can make small changes to reduce their plastic waste, such as switching from disposable to reusable equipment and investing in innovative technology. For example, the NHS removed 200,000 single-use plastic items from its waste in 2019/2020 by switching to reusable equipment. Hospitals can also work together to pressure manufacturers to reduce excessive packaging and provide more environmentally friendly products.
