This obviously makes the results less accurate, but it can still be used as a general indicator of impact. This study assumed no difference between the devices in terms of clinical efficacy or time for placement.4 Disposable LMAs were discarded in regular municipal solid waste bins after use. Sherman JD, Ryan S. Ecological responsibility in anesthesia practice. Overcash M. Comparison of reusable and disposable medical textiles. Of course the 2.6 billion razors were not, all the same, however, we can still give a ballpark estimate of how many tonnes of plastic/metal waste is being produced every year. In addition, although this life cycle assessment study did not analyze health impacts during use of an LMA, intraoperative exposure to diethylhexyl phthalate (DEHP) is of some concern. Because of its high stability, PPO is a very widely used plastic for many different household items. Gillette Mach3 Disposable Razors for Men, 6 Count, Designed for Sensitive Skin. Reprints will not be available from the authors. The metal is then heated and then cooled slowly to remove any internal stress, which makes it tougher, this process is called annealing (Safety Razor). The Nation's Freight: U.S. Bureau of Transportation Statistics. During a Life Cycle Assessment (LCA), environmental impacts are evaluated throughout the entire life cycle of a product (production, use and disposal or recovery).This also includes the upstream and downstream processes associated with production (e.g., the production of . LMA Classic Product Specifications, 2011, 10. LCA for product sustainability. Tungsten carbide is a carbide compound, made up of equal parts of tungsten and carbon. During the research, I could not find how much energy BIC injection molding machines use, but I did find the energy usage of a common injection molding machine called the Babyplast. #4. In addition to traditional criteria for the selection and purchase of medical devices that include safety, efficacy, and cost, growing awareness of the negative impacts from the practice of health care on the environment and public health calls for the routine inclusion of life cycle criteria into the product selection process. In order to carry out the Eco-Indicator analysis method, the methodology described below has to be followed: Experience spanning from the market-leading environment and climate practice of a global top 10 law firm - to leading Europe's largest . The use of LCA to introduce life-cycle thinking into decision-making for the purchase of medical devices in the NHS. We are proud that it is among the leading professional LCA software . Polystyrene. Wikipedia, Wikimedia Foundation, 2 Dec. 2019, en.wikipedia.org/wiki/Polystyrene. : Uses, Benefits, and Safety Facts, ChemicalSafetyFacts.org,). To begin the process of creating the metal, the tungsten is purified and ground into a fine powder. Research about tungsten is ongoing and includes health effects and risks, degradation processes and an inventory of its use in the defense industry as a substitute for lead-based munitions (EPA). The cheap price of the razor does not reflect the high cost of its waste and impact on the environment. A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. Direct emissions refer to any emissions that resulted from the burning of fossil fuels and Indirect emissions refer to any emissions that resulted from the generation of electricity. Sustainable Development at BIC . 6 Jan. 2011. All of which provides an easy user experience, but, takes a toll on the planet. may email you for journal alerts and information, but is committed It can be used to study the environmental impact of either a product or the function the product is designed to perform. The effect of alternate transport modes was quite small for the reusable LMA but quite significant for the disposable LMAs, leading to a large increase in GHG emissions in particular from air freight. The backbone of LCA is the life cycle inventory (LCI), an analysis of material and energy ows resulting from all phases of the product life cycle.

Select patients who are highly infective warrant the choice of disposable devices; however, data do not support selecting disposables for all patients to avoid any possible risk of infection. Safety Razor. How Products Are Made www.madehow.com/Volume-5/Safety-Razor.html. If the reusable LMA is discarded prematurely, e.g., after 20 uses,16 the unit cost increases to $13 per unit, but decreases to $5.50 if the lifetime can be extended to 80 uses. They have teamed up with Gillette to raise awareness about the massive waste of disposable razors by allowing users to mail their old razors in to be recycled. The final product is then gathered and prepared to go through the final step which is the packaging of razors. The blades are then carefully sharpened to create the razor blades. You may be trying to access this site from a secured browser on the server. Gillette Plastic Disposable Shaving Kit supermax, for Hotel. Despite manufacturer-recommended cleaning processes, and various modifications thereof, proteinaceous material may remain on reusable LMAs.27 Of particular concern, these residues may expose patients to prions causing transmissible spongiform encephalopathy, CreutzfeldtJakob disease. Iatrogenic transmission of the CreutzfeldtJakob disease agent has been reported in >250 patients worldwide, and 6 of these were linked to the use of contaminated equipment, all of which were neurosurgical related. Available at: http://www.cdc.gov/ncidod/dvrd/cjd/qa_cjd_infection_control.htm. These included alternative routes and modes of transport from San Diego to New Haven, changes in autoclave loading practices and efficiency, and varied amounts of PVC in the disposable LMA. endstream endobj 752 0 obj <>stream Anyone can send in razors of any kind, and the plastic and cardboard packaging as well. The largest source of GHG emissions for the disposable LMAs (23%) is the production and polymerization of PVC, the main material constituent. Choosing models that use alternate materials is recommended, particularly because the American Medical Association is urging hospitals and health systems to reduce their use of PVC products, especially those containing DEHP.26 The shipment of LMAs by air also greatly increased overall impacts, pointing to a strategy of bulk ordering from local distributors well in advance of use, and avoiding overnight shipment whenever possible. However, of the 2 billion razors disposed of annually, about 32% end up in the ocean (Kaplan). Life cycle analysis takes into account the following categories: Energy consumption Water consumption Air emissions (including carbon dioxide and other global warming gases) Water emissions Generation of solid waste The majority of life cycle human health impacts of disposable LMAs are caused by PVC use in packaging and the device itself. Safety Razor.How Products Are Made, www.madehow.com/Volume-5/Safety-Razor.html. The metal is heated to a temperature of 1967-2048 degrees Fahrenheit and tungsten carbide has a specific heat of 0.226 BTU/lb/Fahrenheit (Safety razor). It is also often not accepted in curbside recycling, and even when it is, it is not separated and recycled when it reaches the dumping station, making it an unsustainable and wasteful material (Polystyrene. Wikipedia.org). This is the fourth installment in a series of blogs in which weexplore how to design a product for circularity. Phenylene oxide, or PPO, is another common plastic material used in disposable razors. 1. Razor blades dull quickly after repeated use, and are recommended to be used only three to ten times, making them a cheap alternative to reusable cartridges. After the reusable LMA was washed and dried, it was then placed into a heat seal pouch, made of polypropylene film and paper. Disposable razors are a product that can be found in almost any average bathroom. The extraction and consumption of resources (including energy), as well as releases to air, water, and soil, are quantified throughout all stages. h[K#1}\$u@ Additionally, the PVC-dominated material composition of the disposable LMA and associated packaging added significantly to its impacts. Wolters Kluwer Health The product fails to include proper instructions for its waste management, causing it to be disposed of, as the name suggests. According to studies done by the EPA, tungsten steel was originally tested as a stable metal in soil that does not dissolve easily in water (EPA). Bic USAs 2016 registration document provides information about the waste produced during the manufacturing of the razors. Overview. There are three main components in a disposable razor. Wages are then spent on food, entertainment, transport, and other economic activities that themselves have environmental impacts. The laryngeal mask airway (LMA) was introduced into clinical use in the late 1980s and approved by the Food and Drug Administration (FDA) for use in the US in 1991. Swiss Center for Life Cycle Inventories. A 20-mL disposable syringe was used during device placement to inflate the cuffs of both types of LMAs to ensure proper fit, and a procedure was then performed. My next blog post will show some design recommendations using sketches and 3D-printed prototypes. Bic Disposable Razor (1975). Plastics News Europe, 19 Nov. 2009, www.plasticsnewseurope.com/article/20091119/PNE/311199986/bic-disposable-razor-1975. climate change, summer smog, resource depletion, acidification, human health effects, etc. @article{Cordella2015EvolutionOD, title={Evolution of disposable baby diapers in Europe: life cycle assessment of environmental impacts and identification of key areas of improvement}, author={Mauro Cordella and Iris Bauer and Anja Lehmann and Matthias Schulz and Oliver Wolf}, journal={Journal of Cleaner Production}, year={2015}, volume={95 . Chain Management by Life Cycle Assessment (CMLCA) software has been used to conduct the LCA and Ecoinvent 2.01 has been used for life cycle inventory data. From San Diego, both LMAs were assumed to be transported 4700 km by truck to New Haven, CT (70% of shipments in the US are made by truck).13. These few simple materials go through processes of heating, cooling, moulding, cutting, and sharpening throughout their manufacturing process to eventually become the handle, razor blades, and blade cartridge, that will then be assembled to become a disposable razor. This document is an update and merger of two previous EPA documents on LCA ("Life Cycle Assessment: Inventory Guidelines and Principles," EPA/600/R-92/245, and "LCA101" from the LCAccess, website . Though technicians are paid regardless of whether they are cleaning LMAs or are performing some other task, these wages are nonetheless assigned to the reusable LMA on the basis of time spent. The blades do eventually dissipate within the landfill, yet, it is not cost-free, as the tungsten waste can be ultimately harmful to the environment. Facilities that select reusable devices should implement inventory and operating procedures that ensure that devices are reused to the greatest possible extent. After the end of their recommended lifetime, reusable LMAs were also placed in municipal solid waste containers. With the results we supply the basis for strategic decisions for sustainable action. American Society of Anesthesiologists (ASA) Task Force on Infection Control. The major problem with recycling this plastic however, is that during the heating process, the plastic degrades in quality making it less valuable (What Is Tungsten Carbide or Hard Metal?, AZoM.com). BIC Comfort 3 Refillable Three-Blade Disposable Razors for Men, Sensitive Skin Razor for a Comfortable Shave, 1 Handle and 12 Cartridges With 3 Blades, 13 Piece Razor Kit. What IS Life Cycle Assessment? However, BIC did report some of its transportation statistics. The EPA has now stopped tracking the: impact of disposable razors on the environment and has no update on the figure (Olsen). 85 percent of the energy came from electricity, 14 percent came from gas, and the rest came from fuel oil (For You For Everyone Registration Document). When designing a product for circularity it is often difficult to know where to begin. Accessed 28 Nov. 2019. www.thefabricator.com/thefabricator/article/stamping/die-basics-101-intro-to-stamping, https://www.usatoday.com/story/news/nation/2019/08/07/landfill-waste-how-prevent-disposable-razor-plastic-pollution/1943345001/, http://www.greatrecovery.org.uk/resources/3682/, www.plasticsnewseurope.com/article/20091119/PNE/311199986/bic-disposable-razor-1975, www.nytimes.com/1982/04/11/business/how-bic-lost-the-edge-to-gillette.html, www.sciencedirect.com/topics/chemical-engineering/polyphenylene-oxides, www.epa.gov/sites/production/files/2014-03/documents/ffrrofactsheet_contaminant_tungsten_january2014_final.pdf, www.kai-group.com/global/en/kai-factory/process/razor/, www.epa.gov/toxics-release-inventory-tri-program/reducing-trichloroethylene-tce-waste-fabricated-metals-sector, www.madehow.com/Volume-5/Safety-Razor.html, www.recyclingtoday.com/article/the-recycling-potential-of-polypropylene/, www.ssab.com/company/sustainability/sustainable-offering/steel-life-cycle?di=discover21C927E58ECC41198B78D915F7E3E2AF, BEHR Oil Based Interior/Exterior Primer and Sealer, California Academy of Sciences Living Roof Life Cycle, UC Davis Social Sciences and Humanities Building, A-Z List for Digital & Electronics Topics. Once extracted, the tungsten is then shipped to a desired location for it to be manufactured into the metal compound. The total energy consumption of the Babyplast in its four-step molding cycle of setup, fill, cool, and reset was approximately 4.5 kilowatts (Weissman et.al). Another material used is polystyrene. Decision makers have typically favored disposable LMAs because the purchase price is perceived to be less for a comparable quantity of disposable LMAs, in comparison with 1 reusable LMA with its associated labor costs for in-house reprocessing.6. Park Ridge, IL: American Society of Anesthesiologists, 1999, 15. You Asked, We Answered. Chronicle, 12 June 2015, chronicle.kennametal.com/what-is-tungsten-carbide-you-asked-we-answered/. The differences in environmental impacts between these devices strongly favor reusable devices. A Life Cycle Assessment of Disposable Razors. All of these software packages and models are in widespread use by life cycle assessment practitioners in the US and internationally. The main causes of the reusable LMA's environmental impacts are the steam used in the autoclave sterilizing machine and, to a lesser extent, the wastewater generated from washing the LMAs. There are some solutions and new recycling ideas, yet, the reduction of waste for disposable razors is still far off. The 2 LMA options are nearly equivalent in terms of eutrophication impacts, but with different contributions. They are resins that maintain a high dimensional stability, which helps create fast and cheap plastic razor handles (Safety Razor). And then there's the water. In 2016, Bic reduced packaging for their Soleil Razor by 40%. The total amount of Direct emissions from BIC factories was 8,689 tonnes of carbon dioxide (For You For Everyone Registration Document). For climate change impacts specifically, the reusable LMA contributes 7.4 kg CO2e of GHGs over its life cycle, and the equivalent 40 disposable LMAs contribute 11.3 kg CO2e, or approximately the equivalent to burning a gallon (4 L) of gasoline. In this case its the life-cycle of the cartridge-based razor. Dbendorf, Switzerland, 2011, 12. The Eco-Indicator method is a tool developed to help designers conduct a simplified LCA study. For example, LCA results can tell us if one product is environmentally preferable to another . The life cycle assessment results shown here allow clinicians and health care administrators to understand the balance between direct benefits of a given LMA choice to local patient care and the environmental and human health impacts of that choice that occur far from the operating room. Cargo planes and other transport aircraft use jet fuel which produces 135,000 BTU per gallon (Energy Consumption by Mode of Transportation.). Polyphenylene Oxides.Polyphenylene Oxides - an Overview | ScienceDirect Topics, 2013, www.sciencedirect.com/topics/chemical-engineering/polyphenylene-oxides. During shaving, the sharp edges of the blade will chip off at a slow but steady rate, dulling the blade after repeated shavings. %PDF-1.5 % These results will then be used to inform the design process and improve the redesigned razor. The differences in environmental impacts between these devices may present a compelling consideration in device selection when concern for infection transmission is not a factor. Ann Fr Anesth Reanim 2006;25:8114, 7. BIC is voicing their concern about the environmental impact that their large production goals can have. Contribution: This author helped conduct the study and analyze the data. However, given the environmental toll to such a fast accumulating, and non-biodegradable product, waste management must be more considered by both the manufacturers and the buyers. Terracycle is a company that was created to address the issue of recyclable products that often end up in landfills. Once all the components of the razor have been made, the components go to various stations where different tasks will be performed. GaBi includes its own database containing life cycle inventories of processes such as polypropylene manufacturing, transportation, and landfill . The powder is then shaped, usually by the process of die stamping. To make the handle and cartridges, these various plastics are heated together and melted together along with optional colorants and various filler materials. Life cycle assessment is a "cradle-to-grave" approach for determining the financial and environmental costs of a product over its entire life. Complete with an ergonomic shaped non-slip rubber handle for great control and maneuverability and easy rinse blades for 100% better rinsing (vs . Zhang TW, Dornfeld DA. Highly effective in driving partnerships, public policies and projects that accelerate the shift towards a sustainable built environment. There could be hundreds of different sources for their materials. Features Downloads. 0 Plastics are cleaned and pelletized to be recycled into new products, such as picnic tables and park benches. A complete life cycle cost analysis would complement the life cycle assessment results shown here; however, a simple analysis reveals that, assuming full utilization, a $200 reusable LMA costs $5 per use, plus $3 per cleaning for a unit cost of $8, excluding utility and hospital overhead costs. In life cycle assessment, the basis of comparison is called the functional unit. For this report, the functional unit of the disposable and reusable LMAs was taken to be maintenance of airway patency by 40 disposable LMAs or 40 uses of 1 reusable LMA.9 Data collection was specific to Yale New Haven Hospital, including device transportation, cleaning procedures and labor, energy requirements, and disposal. For waste management, switching from 100% incineration to 100% landfilling typically reduced impacts across all categories by 5%10%, with the national average scenario results decreasing in between. On the Venus Gillette company website, they provide the buyer with a guide for choosing which razor is best by asking: When it comes to choosing a razor, how do you know if a disposable or reusable razor is right for you? (What's the Difference Between Disposable and Reusable Razors for Women? Venus)This question, however, only affects the buyers short usage time, and does not provide any information as to the rest of the razors life-cycle after they are ready for a new razor blade and they: throw away the entire razor and grab a new one as recommended by the manufacturer (Venus). E.P.A. Growing awareness of the negative impacts from the practice of health care on the environment and public health calls for the routine inclusion of life cycle criteria into the decision-making process of device selection. The tungsten carbide is then ground into an extremely fine powder in a wet mill process, where metal binders and other metals such as cobalt may be added to increase the metals strength and durability and to help hold the powder together when it is shaped. Sets Strategy to End 'Staggering' Garbage Crisis.The New York Times, The New York Times, 23 Sept. 1988, www.nytimes.com/1988/09/23/us/epa-sets-strategy-to-end-staggering-garbage-crisis.html. To create the metal compound, carbon is added to the purified tungsten in a complex chemical process where the materials are heated to over 2,200 degrees celsius. At the end of applying the additives, the blades are once again heated, to cement the coating onto the blade. Growing awareness of the negative impacts from the practice of health care on the environment and public health calls for the routine inclusion of life cycle criteria into the decision-making process of device selection. Certain practices would further reduce the environmental impacts of reusable LMAs, such as increasing the number of devices autoclaved in a single cycle to 10 (25% GHG emissions) and improving the energy efficiency of the autoclaving machines by 10% (8% GHG emissions). Phase 3: Life Cycle Impact Assessment. Address correspondence to Jodi Sherman, MD, Yale University, School of Medicine, Department of Anesthesiology, 333 Cedar Street, TMP3, New Haven, CT 06520. U.S. Environmental Protection Agency. The next step the blade goes through is called polishing in which is done using strops made out of cowhide to get the desired blade edge shape, the blade is then cut into the sizes of the individual blades, which are then sent off to be inspected. Phoenix: IEEE, 2008, 23. With the amount of waste accumulated from the factories and the bulk of the razors ending up in landfills and oceans, a low price of $1 removes the buyer from how high the cost on the environment a disposable razor is. However, the viability of the disposable razor is always thrown into question because of the sheer amount of resources that it expends. Biro P. Damage to laryngeal masks during sterilization.
