The life cycle impacts of the disposable and reusable LMA options are shown in Figure 2 for all impact categories, on the basis of data from Yale New Haven Hospital. Disposable LMAs are made largely from PVC plastic, which is associated with a number of health concerns that are gaining increased attention.23 Historic efforts to minimize routine medical incineration resulted in the 1998 Memorandum of Understanding between the American Hospital Association and the US Environmental Protection Agency, largely on the basis of recognition of the potential carcinogenic effects of burning PVC plastics. mmw*vA|5v*3n9IUt){e%!HN6@`

The advantage of using this method compared to a more comprehensive LCA method is that its much simpler to carry out and to gather the required information because the data regarding the most common materials and processes has been collected in advance. Reusable LMAs were collected in a dirty device bin on the anesthesia cart and then reprocessed by the anesthesia technicians. Metal materials are sent for smelting and conversion to new alloys (Terracycle). Wages are then spent on food, entertainment, transport, and other economic activities that themselves have environmental impacts. The EPA has now stopped tracking the: impact of disposable razors on the environment and has no update on the figure (Olsen). use/disposable and multiple-use/washable surgical gowns. Staff, RT. Kaplan, Desire. Gillette's slogan 'Gillette - the best a man can get' is famous the world over. All of these software packages and models are in widespread use by life cycle assessment practitioners in the US and internationally. For a number of perioperative textiles, surgical instruments, and anesthetic devices, a life cycle assessment (LCA) has been done and has shown reusables to be environmentally favorable to disposables [ 16, 17, 18, 19, 20, 21, 22, 23 ]. qILL@#nO @8
LCA can be used to compare alternative products, processes or services; compare alternative life cycles for a certain product . 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. Polyphenylene Oxides.Polyphenylene Oxides - an Overview | ScienceDirect Topics, 2013, www.sciencedirect.com/topics/chemical-engineering/polyphenylene-oxides. The Environmental Protection Agency classifies DEHP as a probable carcinogen, and as a possible endocrine disrupter.24 The FDA issued an advisory in 2002 recommending steps be taken to reduce the risk of exposure to DEHP in certain populations.25 There is enough evidence of reproductive and developmental toxicant effects from DEHP for the FDA to recommend alternatives for patients deemed at high risk, namely infants, toddlers, and pregnant and lactating women. B|$5 Gillette Mach3 Disposable Razors for Men, 6 Count, Designed for Sensitive Skin. Sensitivity and simple life cycle cost analyses were conducted to aid in interpretation of the results. Buy Now. On the basis of such criteria, single-use disposable medical devices are increasingly supplanting reusable devices in the United States (US) and elsewhere.1 Although purchase and maintenance costs for disposable devices are perceived to be less than for reusables, this fails to account for indirect costs to society from the environmental impacts attributable to the entire life cycle of a device. Disposable razors are a commonly used item for most Americans, and over two billion razors are thrown away every year in the United States (Shabecoff). It is used to assist companies, consumers, and policy-makers in greening their practices and decisions. Using BEES to select cost-effective green products. Can J Anaesth 2001;48:40912, 22. The high waste from manufacturing and shipping such a small, and cheap product is one that is negatively impacting the planet. 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. 1. BIC is voicing their concern about the environmental impact that their large production goals can have. Through an examination of how the raw materials: carbide steel, tungsten steel, and a combination of the plastics: polypropylene, polystyrene, and phenylene oxide of the razors decompose, and how much waste is accumulated in making the razors, an assessment can be made for the duration of their life cycle. The final value for the cartridge-based razor was 115.06 mPt, and the value for the double edge safety razor was 15.70 mPt. Sensitivity and simple life cycle cost analyses were conducted to aid in interpretation of the results. And then there's the water. Most of those razors just end up in a landfill because most countries are not recycling them. For example, the designer might think that the manufacturing stage would be the most impactful, when in reality for some products its the raw material extraction or its use phase. It all starts with the melting and combining of the desired metal. E.P.A. Ann Fr Anesth Reanim 2006;25:8114, 7. Criteria air pollutants arise for the disposable LMA primarily from the production of ethylene (a polymer precursor) and the combustion of natural gas throughout the system, and for the reusable LMA from the combustion of fossil fuels to produce steam and electricity. The scope of our analysis, as is shown in Figure 1, includes extraction of material and energy resources, manufacturing, packaging and transport from the manufacturing site to the distribution center and the hospital, reprocessing, and eventual disposal. The high levels of pollution from disposable razor blades alone caused the EPA to claim a national garbage crisis in the late 1980s, and the actual figure of 2 billion razors thrown away every year dates back to the 1990s. There is also an additional resin called fluorine resin that is applied to the blades, which allows them to freely glide on the skin. Land transport like trains and trucks use diesel as fuel and that produced 138,700 BTU (Energy Consumption by Mode of Transportation.). Research and Innovative Technology Administration. Put the blades in the steel recycling section. All of which provides an easy user experience, but, takes a toll on the planet. Small components such as inks and labels on the packaging and on the sterilization indicator strips are expected to have negligible impacts and were excluded from the analysis. After that the blades go through a blade edging process, which consists of the blade strips first being coarsely ground by whetstone, second being ground at an angle with a finer whetstone, and then having the tip of the blades ground (Manufacturing Processes). The metal is then quenched in water to bring it to -76 to -112 degrees Fahrenheit to harden the material (Safety Razor). The blades and lubricating strip were too light to be measured with our equipment so their weights were rounded to 1g. Terracycle is a company that was created to address the issue of recyclable products that often end up in landfills. When designing a product for circularity it is often difficult to know where to begin. The next step in the process is the assembly of all the parts. 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). Life cycle impact assessment (LCIA) covers all relevant inputs from the environment (e.g., ores and crude oil, water, land use) as well as emissions into air, water and soil (e.g., carbon dioxide and nitrogen oxides). LCA for product sustainability. In the case of the disposable razor however, it is fairly simple due to its nature. 1.Establish the purpose of the Eco-Indicator calculations In this process, the metal is heated to temperatures of 1,967-2,048F (1,075-1,120C), then quenched in water to a temperature between -76- -112 F (-60- -80 C) to harden it. There is uncertainty in several model assumptions. Chu L, Mathur P, Trudell J, Brock-Utne J. The Bic corporation considers their environmental impact and takes steps to reduce as much waste as possible. Since then, around 60 billion razors have been produced, distributed, and sold worldwide. BIC Group, 2016, For You For Everyone Registration Document. This break-even point will change depending on the category of environmental impact being considered. Health care facilities can decrease their environmental impacts by using reusable LMAs, by selecting disposable LMA models that are not made of certain plastics, and by ordering in bulk from local distributors. However, it is fairly easy to find what the disposable razors components are made of, due to its simplicity. Saudi J Anaesth 2008;2:58. The EPA has said in their 2014 report: Currently, little information is available about the fate and transport of tungsten in the environment and its effects on human health. Finally, the need for manual labor in the cleaning process of reusable LMAs contributed to the costs of these LMAs. 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 . Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. Ans: (i) Significant growth in industry of super premium segment . 5.Interpret and analyse the results. Once in the landfill, it usually takes around 20-30 years to breakdown. 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. We are proud that it is among the leading professional LCA software . 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. 761 0 obj

The next step is to temper the steel at a temperature of 482-752F (250- 400C) and pressed into thin sheets (Safety Razor, madehow.com). Anesth Analg 2004;99:6267, 17. h[K#1}\$u@ The indirect emissions were mostly from the electricity use in the factories. Gillette Mach3 Men's Disposable Razor for Sensitive Skin - Best Cartridge Razor for Sensitive Skin. The environmental impacts of the 2 LMAs were estimated using SimaPro life cycle assessment software and the Building for Environmental and Economic Sustainability impact assessment method. Brimacombe J, Keller C, Morris R, Mecklem D. A comparison of the disposable versus the reusable laryngeal mask airway in paralyzed adult patients. Policy H-135.945: Encouraging Alternatives to PVC/DEHP Products in Health. Overall, reusable LMAs were found to have fewer negative environmental effects in nearly all categories, typically contributing <50% of the impacts of disposable LMAs. BIC put out a report detailing how they deal with the waste from their factories. These impacts are quantified here in terms of energy use, water use, and greenhouse gas (GHG) emissions using general factors for US labor.22. In addition, the impact categories of eutrophication (growth of microorganisms due to excess nutrients) and terrestrial ecotoxicity reflect the impacts on other species and ecosystems and have implications for public health. GaBi is a LCA software that allows its users to connect environmental impacts to a product across its lifespan. This assessment is exceptionally useful as it shows the designer what areas are the most impactful during the products life cycle. On the basis of manufacturer information and density testing, the materials used in the 2 LMAs were identified and their compositions measured using a microgram scale (Table 1). Anesth Analg 1998;87:921, 3. Each time the steam autoclave machine conducts a sterilizing cycle, a large amount of energy is used to heat the steam. The reusable LMA was found to have a more favorable environmental profile than the disposable LMA as used at Yale New Haven Hospital. The Editors of Encyclopaedia Britannica. The more capital-intensive option of increasing the energy efficiency of the autoclave machines by 10% decreases GHG emissions by 8%. Environmental Life-Cycle Assessment of Disposable Bioreactors - BioProcess InternationalBioProcess International Upstream Processing Bioprocessing begins upstream, most often with culturing of animal or microbial cells in a range of vessel types (such as bags or stirred tanks) using different controlled feeding, aerating, and process strategies. The autoclave was typically run with 5 LMAs, although loading varied significantly. It can also help them to compare the newly redesigned product to the original, acting as a benchmark to ensure the design changes are actually positive for the environment. The newest effort to recycle disposable razors is being done in France by BIC, but the company has said that they do not plan on unveiling a recycling program anywhere else yet (Powers). LeBlanc, Rick. Wolters Kluwer Health
What IS Life Cycle Assessment? 2 offers from $9.92. 4. In their study of Life cycle assessment of wastewater treatment technologies treating petroleum process waters, Vlaopolous et al. There are some solutions and new recycling ideas, yet, the reduction of waste for disposable razors is still far off. From mining and extracting the natural tungsten metal, to making the metal alloy and manufacturing just the blade, waste is released. The product has several innovative elements, due to the implementation of eco-design principles, such as: (1) introduction of biopolymers (namely polylactic acid (PLA) and Mater-bi), (2) relevant . In conclusion, disposable razors are being used and thrown away at a rate that is unsustainable for the finite space on the planet. Int Anesthesiol Clin 2010;48:139, 24. The GTG LCIs are added together to give a cradle-to-gate (CTG) life cycle inventory . 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. 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. Available at: http://www.cdc.gov/ncidod/dvrd/cjd/qa_cjd_infection_control.htm. The product doesnt contain any material labels, so the materials have been assumed to be low alloy steel for the body, PP for the plastic parts of the body, EPDM rubber for the grip and an acrylic polymer coating for the lubricating band. There are many detailed stages but the main ones are: extracting and. . We can see how the double edge safety razor has a much lower impact due to the low amount of parts and materials used and the fact that the blade can be separated from the rest of the body and recycled (reducing the overall impact of the product). This short course will give you an introduction to life cycle assessment (LCA) methods and how to apply them in real-life situations.. Life cycle assessment (LCA) is a rapidly evolving tool used to determine impacts of products or systems over a range of environmental and resource issues. However, the viability of the disposable razor is always thrown into question because of the sheer amount of resources that it expends. The final product is then gathered and prepared to go through the final step which is the packaging of razors. Any extra plastic will be discarded, remelted, and reused (Safety Razor, madehow.com). How One Company Keeps Used Razors Out Of Oceans.Green Matters, Green Matters, 25 Sept. 2017, www.greenmatters.com/news/2017/09/25/Z1oInGt/razors-ocean. The studies have not found it to be harmful to drinking water, or public safety, however, it is an ongoing research of soil data that continues. A comparative cradle to grave life cycle assessment (LCA) was conducted to determine and analyze the environmental impacts of using disposable acrylic speculums versus using reusable stainless-steel speculums in a women's university health clinic where around 5,000 pelvic exams are conducted on a yearly basis. Thomas, G.P. There are various ways that the product can get there. What Is Polystyrene? The powder is then shaped, usually by the process of die stamping. BIC may be doing as much as possible to lessen the impact of the production of disposable razors, but due to the massive production it will because unsustainable, because of the energy input, material consumptions, and unrecyclable nature of disposable razors. 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. Nash, Nathaniel C. HOW BIC LOST THE EDGE TO GILLETTE. The New York Times, The New York Times, 11 Apr. Cad M, Webb T, Bjorksten A. 1982, www.nytimes.com/1982/04/11/business/how-bic-lost-the-edge-to-gillette.html. Recycling of Polypropylene (PP). AZoCleantech.com, 25 June 2012, www.azocleantech.com/article.aspx?ArticleID=240. The mixed plastics used in most of the razor take hundreds of years to break down in landfill, and the blades, while the metal is recyclable if separated from the rest of the product, poses a safety hazard for both the consumer and the employees who handle recyclables. 3. Ison E, Miller A. When the devices entered use at Yale New Haven Hospital, both the disposable and the reusable LMAs were removed from their original packaging, which was discarded. The polypropylene is sorted during recycling using a float test that separates it from other materials based on its ability to float due to its weight, then it is often melted down and reused in other product manufacturing. LCA is the most common tool for quantifying the environmental effects associated with a product, process, or service's entire life (Baumann and Tillman 2004).LCA was performed in accordance with the international standards of the ISO 14040 and ISO 14044 . Here's How to Keep Your Razors from Contributing to Landfill Waste. USA Today, Gannett Satellite Information Network, 7 Aug. 2019, https://www.usatoday.com/story/news/nation/2019/08/07/landfill-waste-how-prevent-disposable-razor-plastic-pollution/1943345001/. These are the reasons why I will carry out an Eco-Indicator Assessment instead of a full LCA. It is at this stage that very small amounts of other metals such as iron, silicon, and chromium may be added to the carbide to increase its strength and durability. In 2016, Bic reduced packaging for their Soleil Razor by 40%. By not using air travel and transport, BIC greatly reduces their energy usage and carbon footprint at the same time. Finally, inclusion of the environmental impacts of labor for cleaning (from wages spent on goods and services) only nominally increases the total GHG and water impacts of reusable LMAs. The authors declare no conflict of interest. The use of disposable razors is unsustainable with our growing population and increased demand. 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. An LCA is a life cycle assessment which is completed through research, testing and understanding of the environmental impacts a particular item creates through it's resources use/ production/distribution/disposal. Define the Life-cycle This is an example of a simple product life-cycle diagram. Materials were matched with appropriate life cycle inventory records from the ecoinvent database.11 Injection molding was assumed for the hard plastic pieces (polycarbonate and ABS plastic) and thermoforming for the softer plastics (silicone, polypropylene, and PVC).
