When you take your blades in to the scrap metal center, choose the steel recycling bin. 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. The Potential of Polypropylene.Recycling Today, Recycling Today, 17 July 2019, www.recyclingtoday.com/article/the-recycling-potential-of-polypropylene/. The carbon alloy allows for the metal to be strong enough to be exposed to high levels of moisture without corroding, yet brittle enough to be made into thin blades for a multiple blade razor (Safety Razor). Di(2-ethylhexyl) phthalate (DEHP) Hazard Summary. Overcash M. Comparison of reusable and disposable medical textiles. The LMA, within the heat seal pouch, was then placed in the steam autoclave sterilizing machine (Castle/Getinge MC 3522). The company reported that with their hazardous waste in 2016 11 percent was recycled, 49 percent incinerated with energy recovery, 8 percent sent to land disposal, and 32 percent was sent off to be treated in another way (For You for Everyone Registration Document). Contribution: This author helped design the study and prepare the manuscript. Life-cycle assessment stages Recycling of Polypropylene (PP). AZoCleantech.com, 25 June 2012, www.azocleantech.com/article.aspx?ArticleID=240. However, of the 2 billion razors disposed of annually, about 32% end up in the ocean (Kaplan). During production, two components have to be created which are the blade and the plastic body. The extraction and consumption of resources (including energy), as well as releases to air, water, and soil, are quantified throughout all stages. What Is Tungsten Carbide or Hard Metal? AZoM.com, 2 Aug. 2009, https://www.azom.com/article.aspx?ArticleID=4827. How One Facility Completely Eliminated the Use of TCE Schick Razor Blade Manufacturing in Knoxville, Tennessee. 2017. 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. Packaging is an . An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). After the products make their way to consumers and serve their purpose, the waste must be dealt with. After the end of their recommended lifetime, reusable LMAs were also placed in municipal solid waste containers. "Tungsten Processing." One of the materials used is polypropylene, a thermoplastic addition polymer made from the combination of propylene monomers (Creative Mechanisms Staff, creativemechanisms.com). Assessing all steps in that life cycle provides insight into individual stresses and burden shifts from one step to another and enables understanding of both the cumulative environmental impacts and related trade-offs in each area, throughout the lifespan of both a facility and its manufactured products. To begin the process of making tungsten carbide, the tungsten must first be extracted. 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. 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. To begin the process of creating the razor blades, tungsten carbide, which is the metal that the blades and other optional components are made of, must first be manufactured. 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. Being that it is such a common and quickly replaced product, this is is a major issue in terms of waste. After the plastic body is manufactured it goes through inspections similar to ones the blades go through. American Medical Association (AMA). Where material types were unknown, proxies were assumed from relevant literature,2 although more detailed material information from suppliers would permit a more robust analysis. BIC reported that every year around 2.6 billion of their razors are chosen by consumers every year (Shaver's). The 1% of the material that is recycled however, goes through a 5 step recycling process which is collecting, sorting, cleaning, reprocessing, and producing new products. 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/. Reusable LMAs in general appear to be made largely of silicone, lacking these same concerns for PVC/DEHP. The blades, which are made from a carbide steel made using tungsten carbide, the handle, which is made from a combination of plastics such as polypropylene, polystyrene, and phenylene oxide (PPO), and the cartridge, which is made up of these plastics and sometimes the carbide steel as well (Safety Razor, madehow.com). Polycarbonate production (14%), transportation via truck (15%), thermoforming (13%), and waste disposal (11%) cause the majority of the remaining emissions. Because of its high stability, PPO is a very widely used plastic for many different household items. 1982, www.nytimes.com/1982/04/11/business/how-bic-lost-the-edge-to-gillette.html. This is only the operational energy consumption, but you still have to take into account all the energy used in the design and installation of the machinery. It can be used to study the environmental impact of either a product or the function the product is designed to perform. Once extracted, the tungsten is then shipped to a desired location for it to be manufactured into the metal compound. At every point during planning, production, and even marketing, the quantity of consumption should be analyzed to adjust business models accordingly. LCAs can be used comparatively to assess different product or service design options or to identify environmental . 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). 2006 have considered a process water flow of 10,000 m3/day for a time period of 15 years (system design life) as the function unit used in order to compare the different wastewater treatment processes . #3. 761 0 obj <>/Filter/FlateDecode/ID[]/Index[748 22]/Info 747 0 R/Length 72/Prev 421064/Root 749 0 R/Size 770/Type/XRef/W[1 2 1]>>stream 4.Complete the form The designed short user-time of disposable razors, causes their life cycle to be spent mostly in the landfill where they will remain for hundreds of years due to non-biodegradable plastic, however, recycling the plastic and steel is possible if sent to specific recycling facilities, which could reduce the life cycle and negative impact on the environment. 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. The alloy must allow for easy manufacturing due to the high demand of disposable razors and enough strength to last through transportation and shelf holding. Due to the nature of the disposable razor, they are usually just thrown in the trash and sent off to a landfill. Washington, DC: U.S. Environmental Protection Agency, 2011, 16. They have estimated that they expend around 11.77 gigajoules of energy per ton of their products that they produce (For You For Everyone Registration Document) The BIC report also categorized the energy where they obtained the energy. A life cycle assessment (LCA) is a tool for analyzing the environmental impacts and resources used throughout a product's life, from raw materials extraction to production, and extending through product use and disposal. Contribution: This author helped design the study, analyze the data, and prepare the manuscript. Your message has been successfully sent to your colleague. In order to carry out the Eco-Indicator analysis method, the methodology described below has to be followed: %PDF-1.5 % Eckelman, Matthew PhD*; Mosher, Margo; Gonzalez, Andres; Sherman, Jodi MD. LCA's are completed particularly in relation to how to develop a sustainable world where less waste and more reuse is implemented. 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. Polystyrene is a naturally transparent thermoplastic that is available as both a typical solid plastic as well in the form of a rigid foam material (Rodgers, Everything You Need To Know About Polystyrene (PS).). The 2 LMA options are nearly equivalent in terms of eutrophication impacts, but with different contributions. 769 0 obj <>stream HUO0NpnaJd@"&u[kj-+8=WU\*w)OMYb_ry> 1F3 nyNnb 0 The second component of the razor is the plastic body which is made of a fairly inexpensive plastic called polystyrene. Policy H-135.945: Encouraging Alternatives to PVC/DEHP Products in Health. The blades and lubricating strip were too light to be measured with our equipment so their weights were rounded to 1g. Data Uncertainty. Polypropylene. Wikipedia, Wikimedia Foundation, 30 Nov. 2019, en.wikipedia.org/wiki/Polypropylene. 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. A Life Cycle Assessment of Disposable Razors. Anaesth Intensive Care 2010;38:538, 9. 2. Buy Now. 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). mmw*vA|5v*3n9IUt){e%!HN6@` xcr@pz*Fbiq%1!TJ-CF*1OS|UZU\vQL7M?m'b-,r~S}Y&/{#U6U)S|%q[RB !3j~tj$h>5qtsJ./j?;eosyy*"Z`'wG"M6]O}UKqw[LzY9e B,s&C4++_tI~& Me*lNU"Uigq\u7{:&VNC'rT]FB5jOa.%N%1*stBC]%y&RDs"#&iUX&?8sh:wJo ZjbO|KFmfC{:oX~'b> 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. Uncertainties about the correctness of the model. Life Cycle Assessment (LCA) is a technique for assessing the potential environmental aspects and potential aspects associated with a product (or service), by: compiling an inventory of relevant inputs and outputs, evaluating the potential environmental impacts associated with those inputs and outputs, This means, of the 2 billion razors disposed of annually within the United States, each razor will be on the planet longer than the people who used them. 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. The GTG LCIs are added together to give a cradle-to-gate (CTG) life cycle inventory . Waste is not only a problem when a product is disposed of, but also when it is initially manufactured. Die Basics 101: Intro to Stamping. The Fabricators, 18 July 2018, www.thefabricator.com/thefabricator/article/stamping/die-basics-101-intro-to-stamping. The sheets are then cut out using a process called die stamping, using a tool called a die stamp which is a special, one-of-a-kind precision tool that cuts and forms sheet metal into a desired shape or profile, where the blades are die stamped at a rate of 800-1,200 strokes a minute into the desired shape and size (Hedrick, Die Basics 101: Intro to Stamping.). The steps in LCA are (1) goal and scope definition, (2) life cycle inventory analysis (LCI), (3) life cycle impact assessment (LCIA), and (4) interpretation of the results. 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. Cad M, Webb T, Bjorksten A. Overall, while the materials for disposable razors are few, and the products basic design makes it appear simplistic, the products lifecycle is far from simple. Each time the steam autoclave machine conducts a sterilizing cycle, a large amount of energy is used to heat the steam. Despite this, a general perception is that reusable LMAs possess a safety profile inferior to that of disposable LMAs, thus contributing to the proliferation of the latter. Case Studies. Case Studies : Reducing BIC's Rejection Rates | KEYENCE America, www.keyence.com/solutions/case-studies/bic.jsp. If all 2.6 billion of those razors each weight 8.8 grams, then the total amount of waste produced would be around 25,220 tonnes. 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. The Eco-Indicator method is a tool developed to help designers conduct a simplified LCA study. Questions and Answers: CreutzfeldtJakob Disease Infection-Control Practices. A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. EPA. Disposable BIC razors are hollow and made using injection molding, but making the razors hollow is only possible because of the fluid nature of polystyrene (The Bic Razor, Still the Sharpest of the Bunch.). However, they also affirmed that they strive to make their products with an eco-design approach by using recycled materials or bioplastics in their different products (For You for Everyone Registration Document). 2 offers from $9.92. hbbd``b`z$k@D Since then, around 60 billion razors have been produced, distributed, and sold worldwide. This points to the need for effective inventory control, which is also critical for the reusable devices because there needs to be a sufficient number clean and on hand while another batch is undergoing cleaning, sterilization, and cooling. Polyphenylene Oxides.Polyphenylene Oxides - an Overview | ScienceDirect Topics, 2013, www.sciencedirect.com/topics/chemical-engineering/polyphenylene-oxides. Technical Fact Sheet-Tungsten.Technical Fact Sheet- Tungsten, EPA, Jan. 2014, www.epa.gov/sites/production/files/2014-03/documents/ffrrofactsheet_contaminant_tungsten_january2014_final.pdf. Resources, Conservation & Recycling 156 (2020) 104704. In this case it was very difficult to see what materials the product contained and exactly how it was manufactured (as the big manufacturing companies wouldnt disclose this information), so some of the data had to be assumed. a 4.1% (Bic). Disposable Razors in Bulk, Bulk Razors with Knife Caps, Individually Packaged Disposable Razors Bulk, Suitable for Hotels, Shelters, Homeless People, Nursing Homes, Charities, Churches (60) 4.2 4.2 out of 5 stars (9) $22.39 $ 22. : Uses, Benefits, and Safety Facts, ChemicalSafetyFacts.org,). 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. London 45. The original LMA was a reusable device (Intavent International SA, Henley-on-Thames, UK). The study found that: Pollution of the oceans from plastics has become an increasingly large issue that researchers are still assessing. The EPA has now stopped tracking the: impact of disposable razors on the environment and has no update on the figure (Olsen). BIC is voicing their concern about the environmental impact that their large production goals can have. Gillette Razor Local Recycling Solutions.TerraCycle, www.terracycle.com/en-US/brigades/gillette-local-recycling. The use of LCA to introduce life-cycle thinking into decision-making for the purchase of medical devices in the NHS. There could be hundreds of different sources for their materials. 0 Reusable LMAs were collected in a dirty device bin on the anesthesia cart and then reprocessed by the anesthesia technicians. After getting the sharpened blade they are coated with a thin film to allows them to not lose sharpness after only a few shaves (Manufacturing Processes). J Environ Assess Policy Manage 2000;2:45376, 2. This is because of the complexity of the life cycle, from the acquisition of materials to the management of a product at the end of its life. Please try after some time. Metal materials are sent for smelting and conversion to new alloys (Terracycle). After that, the metal is pressed down to the desired blade thickness which is around 1mm (Manufacturing Processes). The total amount of Direct emissions from BIC factories was 8,689 tonnes of carbon dioxide (For You For Everyone Registration Document). Weissman, Alexander, et al. The human-health-related impact categories are pertinent to those developing standards for the delivery of health care. 13, 14 There are few published life cycle assessment studies of medical items (ref. Nash, Nathaniel C. HOW BIC LOST THE EDGE TO GILLETTE. The New York Times, The New York Times, 11 Apr.
