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. 13, 14 There are few published life cycle assessment studies of medical items (ref. Put the blades in the steel recycling section. If you count the actual razor cover (if you haven't lost it long ago) then it will be four pieces for recycling. Steel Life Cycle.SSAB, www.ssab.com/company/sustainability/sustainable-offering/steel-life-cycle?di=discover21C927E58ECC41198B78D915F7E3E2AF. In conclusion, disposable razors are being used and thrown away at a rate that is unsustainable for the finite space on the planet. Powers, Matt, and Amanda M. Can You Recycle Disposable Razors? Earth911.Com, 30 July 2019, earth911.com/living-well-being/health/can-you-recycle-disposable-razors/. This LCA is specific for surgical gowns used in the Twin Cities of Minneapolis and St Paul, Minnesota. The following document provides an introductory overview of Life Cycle Assessment (LCA) and describes the general uses and major components of LCA. In phase 3, we evaluate how significant the impacts are. Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. There is also an additional resin called fluorine resin that is applied to the blades, which allows them to freely glide on the skin. Our team of experts has many years of experience in the ecological evaluation of products and services. Therefore, to help designers get started and make informed decisions, a Life cycle Analysis (LCA) can be carried out using the information gathered during the research stage. For You For Everyone: Registration Document.Bic World, Bic, 2016, www.bicworld.com/sites/default/files/2017-03/BIC_DRF2016_EN.pdf. The EPA has now stopped tracking the: impact of disposable razors on the environment and has no update on the figure (Olsen). Composition Assumptions for Disposable and Reusable Largyngeal Mask Airways (LMAs). The most important sources of impacts for the disposable LMA were the production of polymers, packaging, and waste management, whereas for the reusable LMA, washing and sterilization dominated for most impact categories. 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). BIC put out a report detailing how they deal with the waste from their factories. The majority of eutrophication impacts from disposable LMAs are from deposition of nitrogen oxide particulates from electricity generation and waste incineration, and impacts for the reusable LMA are nearly all from wastewater used in the cleaning process. Goodman EJ, Haas AJ. International Sympsium on Sustainable Systems and Technology. Waste is not only a problem when a product is disposed of, but also when it is initially manufactured. The life of a typical razor blade is not an easy one. 3 in Table 1). 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). Reducing Trichloroethylene (TCE) Waste in the Fabricated Metals Sector.EPA, Environmental Protection Agency, 9 Aug. 2016, www.epa.gov/toxics-release-inventory-tri-program/reducing-trichloroethylene-tce-waste-fabricated-metals-sector. After that, the metal is pressed down to the desired blade thickness which is around 1mm (Manufacturing Processes). 3. This is where most of the complexity of an LCA is involved. After the products are packaged, there has to be a way for them to get to the end consumer. The study found that: There are various ways that the product can get there. The specific type or blend of plastic for BIC razors is used is called polystyrene (Europe). Camera visual inspection is performed and This is all to ensure BICs quality standards are being met and ensure a quality product. Finally, the razors are packaged in cardboard and plastic, and shipped out to stores and markets globally for customers to purchase and use. 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. Phase 3: Life Cycle Impact Assessment. After the end of their recommended lifetime, reusable LMAs were also placed in municipal solid waste containers. During shaving, the sharp edges of the blade will chip off at a slow but steady rate, dulling the blade after repeated shavings. The aim of this paper is to analyse substitutes to disposable plastic tableware using the Life Cycle Assessment methodology. 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. Manufacturing Processes (RAZOR): KAI FACTORY: KAI Group. KAI FACTORY | KAI Group, www.kai-group.com/global/en/kai-factory/process/razor/. After the reusable LMA was washed and dried, it was then placed into a heat seal pouch, made of polypropylene film and paper. 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). endstream

WC2N 6EZ, Redesigning the razor Life Cycle Assessment. The use of LCA to introduce life-cycle thinking into decision-making for the purchase of medical devices in the NHS. Eshwar Shop. 2.Define the life-cycle Each year in Italy, millions of tons of fruits and vegetables are harvested, packed and transported to national and foreign retail outlets. The number of times an LMA is reused is a particularly uncertain assumption, because there have been reports of premature disposal.16 Use in excess of the manufacturer recommended 40 times has also been reported,17 and 100 to 200 uses appears to be possible with proper handling and preuse checks.1821 Here, 10, 20, 30, 60, 80, and 100 cycles are considered as alternative assumptions. This was a cradle-to-grave study that included inputs and outputs for the manufacture, transport, use, and waste phases of the LMAs. Comparative environmental and human health (HH) impacts for disposable and reusable laryngeal mask airways (LMA), Building for Environmental and Economic Sustainability (BEES) impact assessment method.

An updated lifecycle assessment for disposable and reusable nappies Report that looks at the effect of disposable and reusable nappies on global warming and other environmental impacts. Introduction Paper diapers are roughly divided into two types: those for infants and those for adults. Address e-mail to [emailprotected]. your express consent. The body of both razors had similar impact as their weights were also quite similar. American Medical Association (AMA). Research and Innovative Technology Administration. Since BICs products do not go to a single location it is impossible to give an exact number for BICs energy usage in transportation. I found information about the whole blade manufacturing process, but could not find details about energy consumption in every step of the process. 45. The US Environmental Protection Agency's Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) life cycle impact assessment method was used to model environmental impacts of greenhouse gases and other pollutant emissions. They also reported how they dealt with their non-hazardous waste 76 percent was recycled, 11 percent incineration with energy recovery, 10 percent was sent to land disposal, and the remaining 3 percent was sent off for a different treatment (For You for Everyone Registration Document). The LCA is broken into four stages: Defining the goal and scope how much of a product's lifecycle will be addressed, the reasons for carrying out the assessment, the intended audience, and the intended end-use [] 3. Swiss Center for Life Cycle Inventories. Polystyrene is not biodegradable and takes hundreds of years to break down. Life Cycle Approach to Plastic Pollution - Life Cycle Initiative Our news to your inbox Click to subscribe to LC Net info@lifecycleinitiative.org About Us Our Activities & Tools Reports & Training News & Events Get Involved Life Cycle Approach to Plastic Pollution Activities Life Cycle Assessment in High-Impact sectors 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. Once the plastic has cooled, the pieces are released from the moulds. U.S. Environmental Protection Agency. GaBi is a LCA software that allows its users to connect environmental impacts to a product across its lifespan. qILL@#nO @8
Yet, as they are designed to be thrown away after use, a question is raised of their fast accumulating waste and its impact on the environment. Overcash M. Comparison of reusable and disposable medical textiles. 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. 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).). Once all the components of the razor have been made, the components go to various stations where different tasks will be performed. Disposable and reusable LMAs typically differ in material composition, packaging, reuse, and cost. McGain F, McAlister S, McGavin A, Story D. The financial and environmental costs of reusable and single-use plastic anaesthetic drug trays. Terracycle. Safety Razor. How Products Are Made www.madehow.com/Volume-5/Safety-Razor.html. Goal, scope and background The industrial packages sector has great importance for the transport sector in Europe. To bring the metal to its final form, it is heated to extremely high temperatures to remove the binders, and to mold the metal particles together, in turn, creating a very strong and durable metal compound (Siddle, How Is Tungsten Carbide Formed?). 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. Anaesthesia 2000;55:7001, 18. Washington, DC: U.S. Bureau of Transportation, 2002, 14. 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. Where regulations permit, disposal of LMA-related waste as regular municipal waste, as opposed to biohazardous waste, should also reduce the adverse health effects stemming from medical waste incineration. A 2005 analysis published by U.K. Ann Fr Anesth Reanim 2006;25:8114, 7. Lv, Andrea Lind, and Tigist Fetene. These impacts are quantified here in terms of energy use, water use, and greenhouse gas (GHG) emissions using general factors for US labor.22. When designing a product for circularity it is often difficult to know where to begin. The cartridge-based razor had a slightly higher impact due to the rubber parts which cant be separated from the plastic body. 2 offers from $9.92. Reprints will not be available from the authors. However, by looking at just this one company, there is a sense of the massive amount of direct and indirect emissions from just the making of razors that are thrown away so quickly after use, with an increase annually of users. Gillette Mach3 Men's Disposable Razor for Sensitive Skin - Best Cartridge Razor for Sensitive Skin. The metal that can be used in the cartridge is also cut out during this stage. It can be used to study the environmental impact of either a product or the function the product is designed to perform. Most of those razors just end up in a landfill because most countries are not recycling them. The natural half life of a large stock of reusable laryngeal mask airways at a teaching hospital. 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). 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. These steps are not necessarily conducted in succession, but iteratively. 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. An LCA is an accounting of the inputs and outputs for a product system, beginning with extraction of raw materials from the earth and continuing through all of the steps of transportation, manufacturing, product fabrication, product use, and end-of-life, which may include reuse, recycling . Current LMA procurement decisions are typically based on perceived costs. Applying this method of assessment is complex and difficult and translating the theory into a . The extraction and consumption of resources (including energy), as well as releases to air, water, and soil, are quantified throughout all stages. Sensor3 disposable razors for men feature an enhanced Lubrastrip with water activated Comfortgel technology for ultra-gentle shaving on your sensitive skin. The plastic, however stable for the user, remains stable long after it is thrown away as well. Polypropylene is recyclable with the resin code of 5, which is its numbered identification code that is used to identify what resins plastic products are made of, and indicate how they are recycled. The stability of the plastic components, while necessary for shelf stability and use, takes longer than one persons life-span to decompose. Flying staff to meetings, shipping, and distributing the product is the highest offender for the planet. A life cycle assessment (LCA) is used to identify the environmental risks of existing and planned products, services and manufacturing processes as well as identify strategic improvement opportunities. 3.7.Product Life Cycle Analysis . Brimacombe J, Keller C, Morris R, Mecklem D. A comparison of the disposable versus the reusable laryngeal mask airway in paralyzed adult patients. 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). 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. Since then, around 60 billion razors have been produced, distributed, and sold worldwide. 1.Establish the purpose of the Eco-Indicator calculations These results will then be used to inform the design process and improve the redesigned razor. Manufacturers can do this solely by machine or by human eye/hand plus machine for extra quality assurance. 748 0 obj

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. GaBi includes its own database containing life cycle inventories of processes such as polypropylene manufacturing, transportation, and landfill . Finally, the assessment will be carried out on the new design to assess if it has a lower impact than the other options analysed. LCA's are completed particularly in relation to how to develop a sustainable world where less waste and more reuse is implemented. The largest difference in environmental impacts is seen in the impact category of carcinogenesis, in which reusable LMAs cause 5% of the impacts of disposable LMAs. However, of the 2 billion razors disposed of annually, about 32% end up in the ocean (Kaplan). Case Studies. Case Studies : Reducing BIC's Rejection Rates | KEYENCE America, www.keyence.com/solutions/case-studies/bic.jsp. Such an analysis is commonly performed using life cycle assessment. Park Ridge, IL: American Society of Anesthesiologists, 1999, 15. In the late 1990s, disposable LMAs became available. This makes it an easy and quick method to start the analysis of a product and aid the designer when creating alternative concepts which are more environmentally friendly, because they can clearly identify what areas need improvement and which ones work well already. The disposable LMA consisted largely of polyvinyl chloride (PVC) plastic, and the reusable LMA consisted primarily of silicone. Siddle, Dave. 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. Both were assumed to be transported to Los Angeles, CA, by container ship, and from there by truck to the company distribution center in San Diego, CA. Contact Supplier. Each manufacturing plant or node in the supply chain is referred to as agate-to-gate (GTG) life cycle inventory. This is shown through their commitment to their eco-design process and new recycling programs that are undergoing testing. Acta Anaesthesiol Scand 2009;53:6878, 19. 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. LMAs may be composed of 40% DEHP by weight. 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. 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. This practice meets American Society of Anesthesiologists' recommendations for infection control for equipment requiring high-level disinfection.14. LCAs can be used comparatively to assess different product or service design options or to identify environmental . Scope of the life cycle assessment for disposable and reusable laryngeal mask airways (LMAs). However, because of the new awareness to their wasteful impact on the environment, some companies have begun to provide solutions to the disposable razor issue. The cheap price of the razor does not reflect the high cost of its waste and impact on the environment. Olsen, Alexandra. 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).
