Hospitals are filled with single-use plastic, but environmental advocates are seeking less wasteful options
Hospitals are major consumers of single-use plastics, with sterile plastic items being commonplace in operating rooms. Practice Greenhealth, a non-profit working to make hospitals more sustainable, estimates that 25% of hospital waste is plastic. A single hysterectomy procedure, for example, can produce up to 20 pounds of waste, most of which is plastic. Single-use plastic is an attractive option for hospitals due to its affordability, durability, and convenience, providing a fresh, sterile environment for each new patient. However, environmental advocates are seeking less wasteful alternatives to address the significant contribution of hospitals to plastic pollution.
The issue of plastic waste in the healthcare sector is gaining attention, with nurses and healthcare professionals playing a crucial role in driving change. Nurse Mette Skriver Revsbech from Copenhagen University Hospital highlighted the large volume of plastic waste generated by just five surgical procedures, underscoring the urgency of taking action. Initiatives such as collecting used oxygen masks and implementing recycling schemes have emerged, with nurses often taking the lead.
Recycling hospital plastic waste is challenging due to sorting and cleaning difficulties. Different types of plastics have varying melting points, making recycling complex. Additionally, producing enough recyclable material to attract recyclers is a hurdle for individual hospitals, as it is more feasible when waste is aggregated from multiple sources. However, some hospitals have successfully partnered with recycling companies to divert clean medical plastics from regulated medical waste streams. Single-stream recycling programs, for instance, eliminate sorting time while accommodating various plastics from operating rooms.
To address the plastic waste issue, hospitals can adopt reusable items in place of single-use plastics. Practice Greenhealth's survey of 332 hospitals found that certain items, such as surgical basins and sterilization wraps, can be effectively replaced by reusable alternatives, leading to significant waste reduction. Additionally, proper coordination between the healthcare sector and recycling industries is vital to improving medical plastic recycling. New recycling technologies and eco-friendly product designs are also essential components of a sustainable future for the healthcare industry.

Recycling is impossible for some plastics due to varying melting points
Interest in recycling hospital plastic waste is growing, and nurses' commitment to collecting and recycling these materials is crucial to the 'green transition of healthcare'. Hospitals are filled with sterile single-use plastic, and environmental advocates are seeking less wasteful ways to maintain hygiene.
While recycling hospital plastics is a priority for many, it is not always a simple process. Some plastics cannot be melted down and recycled due to their varying melting points. For example, an oxygen mask can be made with two different types of polymers, which cannot be recycled together due to their different melting points.
Some plastics have a higher melting temperature than their self-combustion temperature. This means that even in a vacuum, they will not melt but will instead combust, turning into charcoal instead of molten plastic. Additionally, melting some plastics can release toxic chemicals, which can be harmful if inhaled.
However, some plastics, such as thermoplastics, can be melted and remoulded multiple times, although the quality of the plastic will likely degrade with each phase of melting and remoulding.

Sterilization wraps and other common plastic materials can be effectively recycled
Sterilization wraps, also known as "blue wrap," are commonly used to cover and safeguard surgical equipment and tools. These wraps are made from polypropylene, a type of plastic that can be recycled or upcycled. Recycling sterilization wraps can help reduce landfill waste and incineration, contributing to the sustainability initiatives of medical facilities.
Several companies, such as Iron Mountain, offer sterilization wrap recycling services. These services provide collection containers for uncontaminated sterilization wraps, which are then transported off-site for recycling through molecular or mechanical processes. The recycled output can be used to create new plastic products, reducing the demand for virgin plastic.
In addition to sterilization wraps, other common plastic materials in hospitals that can be recycled include irrigation bottles, basins, pitchers, trays, flexible clear packaging, and Tyvek. These items are often made from polypropylene (PP) or high-density polyethylene (HDPE) and can be recycled through single-stream recycling programs, eliminating the time-consuming sorting process.
The recycling of hospital plastic waste is an important aspect of the green transition of healthcare. Nurses and other healthcare professionals play a crucial role in collecting and recycling these materials, and their commitment is essential to reducing plastic waste in the medical industry.

Nurses play a crucial role in collecting and recycling plastic waste
Nurses have first-hand experience of the sheer volume of plastic waste generated by hospitals. They see the waste generated by each patient and by each surgical procedure. For example, a single hysterectomy can produce up to 20 pounds of waste, most of which is plastic. It is often nurses who are initiating plastic collection schemes and encouraging colleagues to participate in projects to reduce plastic waste.
Nurses are also well-placed to identify opportunities to recycle. They can separate clean medical plastics from regulated medical waste and solid waste bins. They can also identify items that can be replaced by reusable ones, such as surgical basins and sterilization wraps. Nurses can also encourage vendors to explore membership of organizations like the Healthcare Plastics Recycling Council, which offers a toolkit for hospitals looking for a recycling network to join.
In addition, nurses can take individual action to recycle plastic waste. For example, nurses can collect and donate unused medical supplies to charities like the Brother's Brother Foundation, which donates internationally. Nurses can also take simple actions like rinsing out plastic items and placing them in recycling bins, or collecting spent batteries.

Hospitals can save thousands of dollars by switching to reusable surgical tools
Hospitals and medical care facilities are increasingly concerned about reducing their plastic waste and transitioning to more sustainable practices. Single-use plastic is prevalent in hospitals, and a single hysterectomy procedure can produce up to 20 pounds of waste, most of which is plastic. This waste includes commonly used items like sterilization wraps, irrigation bottles, basins, pitchers, trays, and packaging. While single-use plastic offers a convenient and sterile option, it contributes significantly to the environmental footprint of the healthcare industry.
To address this issue, hospitals can switch to reusable surgical tools and equipment, which has the potential to reduce waste and save thousands of dollars annually. Practice Greenhealth, a non-profit organization promoting sustainable practices in healthcare, found that replacing single-use plastic items in operating rooms with reusable alternatives can lead to significant cost savings. For example, switching from disposable metal paracentesis blades to diamond blades saved a doctor $19,000 in the first year and $118,000 over five years. Reprocessed and "reposable" instruments, which are labeled for multiple uses, offer cost-effective alternatives without compromising sterility or patient safety.
Surgeons and medical professionals play a crucial role in driving the transition to reusable surgical tools. Some surgeons make personal decisions about reusing equipment, prioritizing quality and sterility. For example, Dr. Kenneth R. Kenyon of Cornea Consultants in Boston chooses instruments based on both quality and sterility, opting for conventional instruments over disposable ones in certain cases. Richard J. Ruckman, MD, also highlights the cost savings of reusable diamond knives over disposable metal ones, citing a five-year lifespan with proper maintenance.
However, there are conflicting opinions among medical professionals regarding the safety and effectiveness of reusable surgical tools. Some surgeons refuse to reuse equipment due to concerns about patient safety and legal ramifications. Studies examining the sterility of reusable versus disposable equipment have not provided conclusive evidence, leaving the decision to the discretion of individual surgeons and hospitals. Nonetheless, proper reprocessing, maintenance, and repair of reusable surgical tools are critical to ensuring their safety and longevity.
By switching to reusable surgical tools, hospitals can not only reduce their environmental impact but also make significant cost savings. With the support and involvement of medical professionals, hospitals can strike a balance between hygienic practices and sustainability, contributing to a greener healthcare industry.
