Are We Doing Enough To Save The Planet? No, more needs to be done, and this article from savewhere.net explores the various facets of environmental sustainability, offering insights and practical solutions for creating a more sustainable future. To secure our future, we need a multi-faceted approach to conservation, emphasizing responsible resource management, technological innovation, and a shift in lifestyles that respect the environment.
1. Understanding Hospital Waste Management
Hospital waste consists of general, infectious, pathological, sharps, pharmaceutical, cytotoxic, and radioactive materials. General waste, being non-hazardous, can go straight to landfills. However, clinical waste must be treated before disposal via incineration, autoclaving, microwaving, or chemical treatments, as noted by Wyssusek et al. Medical waste is often incinerated, a practice examined by Babu et al. and Yates et al. Incineration effectively handles most waste types except radioactive ones, reducing waste volume and weight. Still, it releases toxic fumes like hydrochloric acid, dioxins, furans, and heavy metals, as highlighted by McLeod, Melamed, and Wyssusek et al. Incinerating 1 kg of clinical waste produces roughly 3 kg of CO2, according to Southorn et al., suggesting that non-incineration methods should be favored or incineration emissions strictly regulated, as Melamed argues.
One study showed that 50–85% of operating theatre (OT) waste that should have been general waste was incorrectly disposed of as clinical waste, as noted by Kagoma et al. Recyclable materials like paper, plastics, cardboard, and packaging were also wrongly classified as general waste, as Shinn et al. pointed out. This indicates a failure in waste segregation within clinical settings, as Pegg et al. and Wyssusek et al. have observed. Waste misclassification leads to poor recycling practices and can increase treatment and disposal costs up to 20 times, as Wyssusek et al. mentioned.
1.1. Costs Associated with Waste Disposal
| Waste Type | Disposal Cost |
|---|---|
| General Waste | Lower, varies by location |
| Clinical Waste | Significantly higher than general waste |
| Recyclable Waste | Can generate revenue |
1.2. Reasons for Waste Misclassification
Reasons for incorrect waste segregation include a lack of understanding of what constitutes clinical waste, complacency, and fear of being reprimanded, according to Wyssusek et al. Items frequently misclassified are urinary catheters, suction catheters, oxygen masks and tubing, prep sticks, and nasogastric tubes, as Perrego noted. These should only be put in clinical waste bins if visibly soiled with blood or bodily fluids, as Beloeil and Albaladejo, and Wormer et al. specified.
Waste segregation should be performed by the person who generates the waste, close to where it is produced, as Wyssusek et al. advised. To encourage proper waste separation, bins should be clearly labeled with signage and examples, as Kagoma et al. suggested. Positioning recycling bins to be easily accessible and clinical waste bins further away can also reduce misclassification, as Brassil and Torreggiani found. Brassil et al. discovered that waste is 60% more likely to be incorrectly segregated if the risk bin is closer to the interventionalist than the non-risk bin. Clinical waste can be halved by separating waste generated before the patient enters the OT, because pre-operation waste is usually general waste, as Hubbard et al. and Wyssusek et al. reported.
2. Addressing Excess Packaging and Procedure Packs
Interventional radiology (IR) procedures generate significant hospital waste due to extensive packaging and single-use items. Clements et al. found that packaging for IR products makes up 54.8% of the total weight, with 76% being recyclable. Brassil and Torreggiani noted that almost all packaging from common IR devices is recyclable, but it’s often misplaced in general or clinical waste bins, which have disposal costs of €130/tonne (USD 128/tonne) and €813/tonne (USD 801/tonne), respectively. They also found that 12% of peripherally inserted central catheter (PICC) set components and 14% of port set components in procedure packs are never used but still disposed of, while additional items are opened to compensate. Each PICC insertion procedure produces an average of 41.5 kg of CO2, according to Bolger et al. Optimizing packaging recycling can salvage 35% of the material, significantly reducing CO2 emissions.
IRs should collaborate with suppliers to redesign procedure packs to minimize unnecessary items and packaging, as Brassil and Torreggiani recommended. Procedure packs should be reformulated to remove items not regularly used and package them separately for occasional use, as Van Norman and Jackson suggested. Additionally, packaging can be repurposed to minimize waste. For example, Egan and Cheng described using Bair Hugger packaging as a keyboard cover to improve OT hygiene.
3. Optimizing Inventory Management
IR suites often have a wide range of inventory, some rarely used but kept for emergencies. Devices may remain unused and be discarded after their expiration, as Demmert and Hong noted. This increases financial burden and creates waste. To limit waste from expired inventory, adopt the “first in, first out” method, consignment programs, or rotate materials to the supplier before expiration, as Baerlocher et al. suggested.
3.1. Incentive Programs for Inventory Use
In a large US-based IR department, staff received incentives (USD 5 coffee gift cards) for using equipment nearing expiration, as reported by Demmert and Hong. Over 13 months, USD 135,859.65 worth of equipment was used before expiry out of USD 422,732.65 worth of equipment, reducing wasted supplies by almost 50% and costs by 31.3%.
3.2. Environmentally Preferable Purchasing
Prioritize products based on environmental impact and long-term cost from production to disposal, as Yates et al. advised. A study found that 72% of suppliers to a university hospital operating room (152 out of 211 companies) do not promote sustainability, indicating that purchasing decisions are often based solely on price or quality, according to Schieble.
4. Reducing Waste from Opened but Unused Items
One study examined the cost of single-use items opened but not used during neurointerventional procedures, as Rigante et al. did. They found an average waste of €676.49 (USD 666.77) per endovascular procedure and €18.44 per diagnostic angiography case, with aneurysm coiling accounting for the highest waste at €1061.55 (USD 1046.30). Strategies to reduce this include educating staff about interventional waste, using operator preference cards, making prices transparent, discussing waste during sign-out, monitoring department inventory, and promoting price competition among suppliers, as suggested by Rigante et al. and Zygourakis et al. Other suggestions include opening equipment “just-in-time” and improving communication between operators and support staff, as Stall et al. noted.
4.1. Enhancing Team Dynamics
Consistent operator-scrub team combinations optimize team dynamics and improve scrub nurses’ familiarity with operator preferences, leading to better communication and anticipation of needs, which reduces unnecessary waste, as Deshpande et al. reported. Miscommunication, sterile surgical kits, and overpreparation for emergencies are frequent causes of OT waste, with an estimated 26% of single-use supplies opened during surgery going unused, according to Meyer et al.
4.2. Equipment Donation Programs
Unused equipment may be donated to developing countries, medical or veterinary schools, and schools for art projects, as Wyssusek et al. suggested. Organizations like REMEDY at Yale University, InterVol, MedWish, and MedShare collect unused medical supplies and ship them as humanitarian aid, as noted by Chua et al., Guetter et al., and Weiss et al.
5. Understanding and Addressing Costs
It is essential to educate interventional radiologists (IRs) about the costs involved in angiography suites and how they can reduce expenses by opting for less expensive alternatives or avoiding unnecessary items altogether. A cross-sectional online survey revealed that IRs and vascular surgeons have limited knowledge regarding the cost of common devices, as indicated by Wang et al. The survey, involving 1,090 participants, showed that only 19.8%, 22.8%, and 31.9% could correctly estimate the price of devices, Medicare reimbursement, and work relative value units for procedures, respectively. While most respondents expressed a preference for using cheaper devices, only 24.1% had adequate access to hospital pricing information.
Factors such as confidentiality clauses, device monopolies, lack of competitive pricing information, and cost transparency impede clinicians from considering cost when choosing devices, as Wang et al. noted. Another survey among operating theatre (OT) personnel, including nurses, surgical technicians, nurse anesthetists, anesthesiologists, surgeons, and residents, showed a knowledge deficit around item costs, with only 16.4% of estimates accurate to within 50% of the actual price, according to Heiman et al.
6. Implementing the 3 R’s: Reduce, Reuse, Recycle
Implementing the principles of reduce, reuse, and recycle is crucial for minimizing waste in hospital environments.
6.1. Paper Reduction Strategies
To reduce paper waste, Chawla et al. suggested using default double-sided printing, recycled paper, reduced printing of request forms, scrap paper for internal notes, and digital notepads. An audit of neurointerventional procedures revealed significant paper waste from packaging and user manuals that are rarely read, as reported by Shum et al. Digitizing these manuals through online links or QR codes can significantly reduce paper waste. Additionally, electronic referrals and medical records can further reduce paper volumes, as Romero et al. noted.
6.2. Co-mingled Glass and Plastics Recycling
Plastics constitute a significant portion of recyclable waste, with at least 20% of all medical waste being plastic, according to McCain et al. Up to 84% of plastics in the OT are potentially recyclable, as Wyssusek et al. noted. Examples include polyethylene (instrument wraps, saline ampoules, IV fluid bags), polyvinylchloride (oxygen masks, IV fluid bags, suction tubing), and polypropylene (surgical instrument wraps, disposable warming blankets). Plastic pollution has been exacerbated by the increased demand for plastic personal protective equipment during the COVID-19 pandemic.
Hospitals can collaborate with recycling contractors to convert local plastics into furniture, agricultural piping, or artwork, as McGain et al. suggested. Glass and plastic containers from drugs or contrast can be triple-rinsed and recycled, as Schwartz noted. Soft plastics, such as cling wrap, plastic bags, and medical equipment packaging, can also be recycled, according to Shum et al.
6.3. Blue Wrap Recycling and Repurposing
Blue wrap, made of polypropylene, is commonly used in hospitals to protect gowns, toiletries, medical devices, and surgical instruments from contamination. It accounts for 19% of OT waste and 5% of hospital waste, as reported by Babu et al. Although not reusable or biodegradable, blue wrap can be recycled or melted into pellets to create other polypropylene items. Babu et al. launched an 8-week pilot project that collected 1,247 pounds of blue wrap, saving 31.2 cubic feet of landfill space. This project is projected to yield USD 5,000 in revenue annually and save USD 174,240 in disposal and transport costs. Replacing blue sterile wrap with hard metal cases is another environmentally friendly and cost-saving solution, as noted by Pradere et al. and Wyssusek et al. Volunteers have also repurposed blue wraps into ponchos, duffel bags, bedrolls, shopping bags, and sleeping bags for charity, as Wu and Cerceo reported.
7. Reducing Power Consumption
Improving the energy efficiency of radiology and interventional radiology (IR) equipment, such as CT, MRI, fluoroscopy, and PACS monitors, is crucial, as Flowers noted. Heye et al. found that the electricity used by three CT and four MRI scanners over one year could power a town of 852 people. The energy used for each MRI study is similar to the energy required to cool a three-bedroom house with central air conditioning for one day or desalinate 7,000 gallons of fresh water, according to Buckley and MacMahon. Where patient outcomes are not affected, ultrasound can be used as an imaging modality that uses less energy than MRI.
Further research is needed to promote energy efficient hardware and algorithms, according to Buckley and MacMahon. Storage and transmission of large volumes of medical imaging data also require significant energy. Carbon emissions from data centers worldwide may be comparable to those of the global aviation industry, as Buckley and MacMahon noted. Clear guidelines should be developed to minimize unnecessary or redundant data that offers no perceived future benefit.
7.1. Energy Audits and Conservation Measures
An energy audit in an Irish teaching radiology department found that 29 of 43 desktop computers and 25 of 27 PACS reporting stations were left unnecessarily powered after hours, as reported by McCarthy et al. Hainc et al. evaluated the power consumption of 36 reporting workstations, finding that on-mode consumption was 40,763 kWh/a, stand-by-mode consumption was 10,010 kWh/a, and off-mode consumption was 2,397 kWh/a. Power consumption can be reduced by using the auto-shutdown function in computers and PACS monitors or by using energy-saving computers, as Chawla et al. suggested. Skipping the stand-by mode and setting the shutdown wait-time to one hour can reduce power consumption by 45%, according to Hainc et al.
By shutting down workstations and monitors after an 8-hour workday, a radiology department would save 83,866.6 kWh of electricity and USD 9,225.33 annually, as reported by Prasanna et al. This is equivalent to removing 11.6 cars from the road, saving 14.9 barrels of oil, or 39 tonnes of coal, thereby reducing greenhouse gases and carbon emissions. During working hours, monitors should enter sleep mode if not in use for more than 20 minutes, as Schwartz noted.
7.2. Improving Operating Theatre Energy Efficiency
A systemic review found that electricity use constitutes the major carbon footprint within the operating theatre (OT), as noted by Hainc et al. and Rizan et al. Measures to improve energy efficiency in OTs include installing occupancy sensors, low-energy lighting, and energy-efficient air conditioning systems. The largest source of CO2 emissions comes from the electricity and gas used to power the climate control system in the IR suite, as reported by Chua et al. More than half of the heating, ventilation, and air conditioning (HVAC) energy was used during off-hours when the IR suite was rarely in use. Turning off HVAC systems in unused OTs during after-hours can reduce energy consumption by half, as MacNeill et al. found.
Another strategy is to implement HVAC setback in the OTs, reducing the frequency of fresh air exchanges and allowing temperature and humidity settings to fluctuate when not in use, as suggested by Chua et al., Saver, and Yates et al. The Cleveland Clinic saved USD 2 million annually by reducing air exchanges from 20 to 6 times per hour when OTs are not in use, as reported by McLeod.
7.3. Lighting Efficiency
Incandescent bulbs should be replaced with light-emitting diode (LED) lamps, which have longer lifespans, are more energy-efficient, and do not generate unwanted heat or radiation, as Chawla et al. and Yates et al. noted. LED lamps can extend the lifespan of an OT light from 1 to 6 years, resulting in long-term cost savings. An audit of 18 OTs in 11 hospitals in Turkey found that 88.3% did not use sensor controls on lights and 66.7% did not use LED lights, according to Dönmez et al. A teaching hospital in Oregon saved approximately 340,000 kilowatt-hours (kWh) of energy annually, equivalent to saving USD 40,000 per year, by refitting the OTs with LED lights and low-mercury lamps, as reported by Saver. Powering down all anesthesia and OT lights and equipment not in use saved USD 33,000 and reduced annual CO2 emissions by 234.3 metric tonnes, according to Wormer et al.
8. Managing Electronic Devices and Machines Sustainably
Radiology is a technology-centric specialty that relies heavily on electronic equipment. Proper disposal of these devices at the end of their lifespan is crucial for environmental sustainability.
8.1. Recycling Programs for Electronics
Instead of disposing of electronic devices such as computers, scanners, projectors, telephones, printers, toner cartridges, cables, plugs, and batteries, many manufacturers offer recycling programs where these items can be returned and recycled, as noted by Chawla et al. and Schwartz. Hospitals should choose to purchase products from manufacturers with strict green policies who are committed to recycling and reusing their products, as suggested by Beloeil and Albaladejo, Chawla et al., Laustsen, and Saver.
9. Leveraging Teleradiology and Remote Working
The COVID-19 pandemic has shifted working practices, with teleradiology offering a remote working option that reduces long-distance travel and carbon emissions.
9.1. Reducing Travel Emissions
Radiology trainees often travel long distances to their placement sites. Peters et al. found that each trainee in the UK traveled 6,703 miles per year in a car for work or training. Flexible on-call sites reduced the average distance traveled to 6,600 miles per trainee per year, resulting in a 4.3-tonne reduction in CO2 emissions, equivalent to 2.6 return flights from London to New York. Reducing commuting distances also lowers travel expenses, improves safety, and frees up time for clinical duties, according to Peters et al.
9.2. Remote Collaboration and Education
Teleradiology can be used for remote reporting, report checking, teaching, and teleconferencing with multidisciplinary teams, reducing unnecessary travel and improving the environmental sustainability of radiology training, as Peters et al. noted.
10. Conserving Water Resources
Water conservation is essential in hospital settings to minimize environmental impact.
10.1. Hand Hygiene Practices
Alcohol-based hand rubs should be used between cases for surgical scrubbing rather than water, unless visibly soiled, to reduce water and drying towel waste, as Wyssusek et al. noted. This practice is supported by the UK National Institute for Health and Care Excellence (NICE) guidelines. Surgical hand wash for one staff member during a standard 3-minute period uses 18.5 L of water compared to an average of 15 ml of alcohol rub, according to Jehle et al. Switching from scrub soap to alcohol-based waterless scrub solutions could save 2.7 million liters of water a year, as Wormer et al. estimated. For non-surgical hand washing, hand dryers or sanitizers can reduce paper towel waste, as McGain et al. noted.
10.2. Tap Designs
Different tap designs also contribute to water usage. Foot pedal systems had the least water usage per scrub (6.7 L), followed by 45-second timed motion-triggered sinks (7.5 L) and high-flow elbow lever tap sinks (11 L), as reported by Weiss et al. A hospital in the US saved USD 13,750 per year in water costs by installing water-saving retrofits throughout their OT, as Weiss et al. noted.
11. Reusing Medical Supplies and Linens
Reusing medical supplies can significantly reduce waste and costs, promoting sustainability in hospital operations.
11.1. Reusable Sharp Containers
Switching to reusable sharp containers can result in significant cost savings.
By changing to reusable sharp containers, Saver reported an annual saving of USD 70,000.
11.2. Reusable Surgical Linens and Gowns
Items that can be safely reprocessed, such as surgical instruments and gowns, can be reused to reduce the need for single-use supplies, as suggested by Chua et al. Disposable surgical linens amount to 2% of all hospital waste, according to Stall et al. and Wyssusek et al. Surgeons should opt for reusable surgical gowns, drapes, and linens rather than disposable options, as Guetter et al. and Wyssusek et al. advised. Disposable clothing has a greater environmental impact than reusable clothing because reusable gowns use 28% less energy, generate 30% fewer greenhouse gases, and consume 50% less water, as Beloeil and Albaladejo noted.
11.3. Infection Control and Cost Savings
WHO reported no difference in surgical site infections or wound contamination between reusable and disposable equipment, as Guetter et al. noted. Switching to reusable surgical gowns can reduce 63,000 kg of waste and save USD 38,000, as reported by Conrardy et al. Studies support that the use of reusable products generates less waste, has a lower landfill and incineration burden, and costs less in the long run compared to disposable products, according to Conrardy et al. and Weiss et al.
The increasing need for reusable medical equipment has become apparent due to recent shortages caused by the COVID-19 pandemic, as noted by Blough and Karsh. The life cycle, reusability, and recyclability of medical supplies, in addition to their functionality and safety, should be considered in product design using next-generation materials, as suggested by Arepally et al. and Blough and Karsh.
12. Overcoming Barriers to Sustainable Practices
Several barriers hinder the adoption of sustainable practices in healthcare settings.
12.1. Lack of Leadership and Knowledge
Lack of clear guidelines and poor policy implementation make it difficult for staff to embrace green initiatives. Decisions for changing the culture and implementing green policies need to come from leaders and senior management, as suggested by Arepally et al., Benzil, and Kagoma et al.
A survey of hospital surgical staff revealed that 56.7% were uncertain about which OT items are recyclable, attributing this lack of knowledge as the greatest barrier to recycling, as reported by Azouz et al. Ongoing staff education and training are essential to ensure staff know how to segregate waste appropriately, preventing contamination and reducing waste. This could be done through annual waste training requirements or using posters and signs to increase awareness, as Melamed suggested.
12.2. Staff Attitudes and Resistance to Change
Surveys among anesthesiologists showed that while most respondents were interested in recycling, it only occurred in a minority of OTs, as reported by Ard et al. and McGain et al. A cross-sectional study found that satisfactory attitudes toward biomedical waste management did not translate into satisfactory knowledge or better practices, highlighting the need for appropriate training, as noted by Aanandaswamy et al.
12.3. Regulatory and Manufacturing Barriers
An online survey of cataract surgeons and nurses found that 93% believed OT waste is excessive, citing rigid requirements imposed by manufacturers and regulatory agencies on reusing devices as a primary reason, as Chang and Thiel reported. Most believed that manufacturers are driven to produce more single-use products due to increased profit, liability reduction, and lack of carbon footprint considerations.
13. Promoting Staff Education and Awareness
Inform healthcare providers about how their practices affect the environment and the need to take responsibility for minimizing this impact. Departments can measure their carbon footprints, aiming for “green” accreditation through sustainability officers who monitor, educate, advocate, and implement sustainable initiatives, as suggested by Arepally et al. Forming a hospital green team with participants from various disciplines can drive positive healthcare impact on the environment, as Wu and Cerceo noted.
Upchurch suggested using scorecards to track waste and advocating for incentives for surgeons in governing sterile supplies. Benchmarks for carbon footprint should be set to decarbonize radiology, similar to the ALARA principle for radiation exposure, as suggested by Arepally et al. A dedicated waste segregation education program should be implemented, similar to radiation protection programs, as Pradere et al. advised.
| Initiative | Financial Benefits | Environmental Benefits |
|---|---|---|
| Waste Segregation | Reduced disposal costs, revenue from recyclables | Less landfill waste, reduced pollution from incineration |
| Packaging Optimization | Reduced purchase costs, lower disposal fees | Less material usage, reduced carbon emissions from manufacturing and transport |
| Inventory Management | Reduced costs from expired supplies, efficient resource allocation | Less waste from unused items, reduced environmental impact from producing excess supplies |
| Energy Conservation | Lower utility bills, reduced operational costs | Reduced carbon footprint, lower greenhouse gas emissions |
| Water Conservation | Reduced water bills, lower operational costs | Preservation of water resources, reduced energy usage for water treatment and distribution |
| Reusable Medical Supplies | Lower purchase costs, reduced disposal fees | Less waste, reduced environmental impact from producing disposable items |
By implementing these comprehensive strategies, healthcare facilities can significantly reduce their environmental footprint, improve resource efficiency, and promote a more sustainable future.
