To begin the process of creating the metal, the tungsten is purified and ground into a fine powder. Complete with an ergonomic shaped non-slip rubber handle for great control and maneuverability and easy rinse blades for 100% better rinsing (vs . 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. Williams S, Henderson K. A survey into the number of times laryngeal masks are used. Chicago: American Medical Association, 2006, 27. It has a low density and is quite flexible and heat resistant, therefore making it an easily moulded and extruded material. HUO0NpnaJd@"&u[kj-+8=WU\*w)OMYb_ry> 1F3 nyNnb 0 Impact Assessment. 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. However, it is fairly easy to find what the disposable razors components are made of, due to its simplicity. To start the process of making the blades, tungsten carbide is melted at high temperatures. The purpose of this assessment is to compare two different types of razors: cartridge based vs. double edge safety razor. Chu L, Mathur P, Trudell J, Brock-Utne J. Ans: (i) Significant growth in industry of super premium segment . You may be trying to access this site from a secured browser on the server. Innovative and strategic advisor to leading philanthropies, corporates, governments, international institutions and NGOs. Finally, the assessment will be carried out on the new design to assess if it has a lower impact than the other options analysed. 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. The natural half life of a large stock of reusable laryngeal mask airways at a teaching hospital. The extraction and consumption of resources (including energy), as well as releases to air, water, and soil, are quantified throughout all stages. 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. Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2010. These benefits must be weighed against concerns regarding transmission of infection. We purchase the product in a store, use the product for removing unwanted body and facial hair until it eventually dulls, and then we toss it in the bathroom trash, unaware of where it goes or where it came from. The final product is then gathered and prepared to go through the final step which is the packaging of razors. Here we present a life cycle assessment of 2 laryngeal mask airways (LMAs), a one-time-use disposable Unique LMA and a 40-time-use reusable Classic LMA. 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. Our team of experts has many years of experience in the ecological evaluation of products and services. A Comparison Life Cycle Assessment between Razor Blade and Electric Shaver. Dec. 2012. To make the handle and cartridges, these various plastics are heated together and melted together along with optional colorants and various filler materials. This was a cradle-to-grave study that included inputs and outputs for the manufacture, transport, use, and waste phases of the LMAs. GaBi includes its own database containing life cycle inventories of processes such as polypropylene manufacturing, transportation, and landfill . Energy Consumption by Mode of Transportation. Energy Consumption by Mode of Transportation | Bureau of Transportation Statistics, Bureau of Transportation Statistics, www.bts.gov/content/energy-consumption-mode-transportation. A Life Cycle Assessment of Disposable Razors. 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. The Life Cycle Impact Assessment (LCIA) is where the impacts on the environment are calculated. The Fate of the Disposable Razor.Industrial Equipment News (IEN), 7 Aug. 2019, www.ien.com/product-development/news/21081402/the-fate-of-the-disposable-razor. Life cycle assessment of a disposable and a reusable surgery instrument set for spinal fusion surgeries Leiden A, Cerdas F, Noriega D, Beyerlein J, Herrmann C. Life cycle assessment of a disposable and reusable surgery instrument set for spinal fusion surgeries. Europe, Plastic News. Part of this responsible shipping mentality forces them to change their packaging to be able to ship more at a time. Upgrading to a new, energy-efficient autoclave machine leads to a nearly equal reduction in life cycle GHG emissions and may be considered particularly in instances in which older equipment is being used. The total amount of direct GHG emissions in 2016 was estimated at 8,689 teqCO2, i.e. The life cycle for disposable razors must first be assessed by the products design. Gillette Mach3 Men's Disposable Razor for Sensitive Skin - Best Cartridge Razor for Sensitive Skin. This assessment is exceptionally useful as it shows the designer what areas are the most impactful during the products life cycle. During shaving, the sharp edges of the blade will chip off at a slow but steady rate, dulling the blade after repeated shavings. Manufacturer specifications indicate 20 kWh of electricity use for a 5-minute cycle at 135C. 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. Here, Great Recovery Intern Sebastian de Cabo Portugal discusses Life Cycle Assessments. Since BICs products do not go to a single location it is impossible to give an exact number for BICs energy usage in transportation. This is where most of the complexity of an LCA is involved. Disposable razors are made up of three components: a hollowed plastic handle, the razor blade, and the plastic head of the razor that holds the blade (Safety Razor). 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 [] The Nation's Freight: U.S. Bureau of Transportation Statistics. . 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. Figure: Life Cycle Assessment steps: goal and scope definition, life cycle inventory, life cycle impact assessment and interpretation (Sala et al., 2016) In the goal and scope phase, the aims of the study are defined, namely the intended application, the reasons for carrying out the study and the intended audience. What Is Tungsten Carbide?" 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. Poly(p-Phenylene Oxide). Wikipedia, Wikimedia Foundation, 28 Sept. 2019, en.wikipedia.org/wiki/Poly(p-phenylene_oxide). Sherman JD, Ryan S. Ecological responsibility in anesthesia practice. Uncertainties about the correctness of the model. Anaesthesia 2000;55:7001, 18. 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). "Tungsten Processing." 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. A Life Cycle Assessment of Disposable Razors. a Centers for Disease Control. Information on PPO plastics are difficult to find, as most of the data is about how it is made, and the chemical makeup and stability of the plastic, rather than information on the decomposition rate or waste used in the making of it. 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. Brimacombe J, Keller C, Morris R, Mecklem D. A comparison of the disposable versus the reusable laryngeal mask airway in paralyzed adult patients. Teoh W, Lim Y. 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. 13, 14 There are few published life cycle assessment studies of medical items (ref. 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. They are resins that maintain a high dimensional stability, which helps create fast and cheap plastic razor handles (Safety Razor). 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 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 . These results will then be used to inform the design process and improve the redesigned razor. 11,772. 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. Contrary to common expectation, hair is actually pretty hard. (i)What changes occurring in non-disposable Razor category? 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. 15 - 21 Our group recently performed a life cycle assessment of anesthetic drug trays, finding that reusable trays were both environmentally and . . Anesth Analg 2004;99:6267, 17. Atlanta, 2012. The total amount of Direct emissions from BIC factories was 8,689 tonnes of carbon dioxide (For You For Everyone Registration Document). 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. Nash, Nathaniel C. HOW BIC LOST THE EDGE TO GILLETTE. The New York Times, The New York Times, 11 Apr. Reusable LMA cleaning was observed to proceed as follows. Rogers, Tony. Another material used is polystyrene. BIC has noted however that they strive to be as efficient with materials used when it comes to their packaging. Highlights In this post I havent shown the whole process, but there are downloadable links to my full Eco-Indicator results, and to the template form if youd like to carry out an assessment yourself. On the basis of information provided by the distributing company, the disposable LMA was manufactured in Hangzhou, China, and the reusable LMA was manufactured in Singapore. The next step in the process is the assembly of all the parts. For both environmental and cost considerations, management and operating procedures should be put in place to ensure that reusable LMAs are not discarded prematurely. The carbon footprint reported was separated into two sections which are direct and indirect emissions. to maintaining your privacy and will not share your personal information without PPO elements of the disposable razor are hard to determine in years, however, data shows that most plastic items take up to 1,000 years to begin to decompose (LeBlanc). Additionally, the PVC-dominated material composition of the disposable LMA and associated packaging added significantly to its impacts. #4. Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. By not using air travel and transport, BIC greatly reduces their energy usage and carbon footprint at the same time. The aim of this paper is to analyse substitutes to disposable plastic tableware using the Life Cycle Assessment methodology. 39 ($0.37/Count) FREE delivery Thu, Mar 2 on $25 of items shipped by Amazon. A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. 2019, science.howstuffworks.com/environmental/green-science/polystyrene-recycling.htm. 1. The LMAs were first rinsed in tap water, scrubbed externally with a Hibiclens sponge and internally with a small scrub brush, and rinsed again. Silver Spring, MD: U.S. Food and Drug Administration, 2002, 26. In this paper, many details about the life cycle stages were not included. Int J Life Cycle Assess 2001;6:7680, 13. 748 0 obj <> endobj Ison E, Miller A. 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. Differences in environmental impacts between devices may present a compelling consideration in their selection. Biro P. Damage to laryngeal masks during sterilization. Contribution: This author helped conduct the study and analyze the data. 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. 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). 0 8tZ 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. Click the image for pricing & more info. Goodman EJ, Haas AJ. The metal used for the razor blades is called Tungsten Carbide which is used in wear applications, such as shaving (Safety Razor). The high waste from manufacturing and shipping such a small, and cheap product is one that is negatively impacting the planet. For You for Everyone Registration Document. The Great Recovery was a project by the RSA working with Innovate UK which ran between 2012 and 2016. Weissman, Alexander, et al. U.S. Environmental Protection Agency. @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 . There are three main components in a disposable razor. The stability of the plastic components, while necessary for shelf stability and use, takes longer than one persons life-span to decompose. Despite its ability to be recycled, it often ends up in the landfill as many people dont know how to properly recycle it, people are too lazy to recycle, or the plastics arent labeled properly (Polypropylene. Wikipedia). Saudi J Anaesth 2008;2:58. SimaPro is our flagship product: life cycle assessment software that gives sustainability experts, product designers and decision-makers the power to gain insight into the environmental performance of products and services, to define hotspots and to drive positive change. Resources, Conservation & Recycling 156 (2020) 104704. 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. Their carbon footprint was reported with the highest offender being air travel for the product, and staff transportation coming from France: accounting for 73% of the companys annual greenhouse gas emissions (Bic). There much environmentally friendly options when it comes to shavings, such as the traditional safety razor and straight razors, which can have a much longer life than disposable razors. But this is expected from a large brand like Gillette. From mining and extracting the natural tungsten metal, to making the metal alloy and manufacturing just the blade, waste is released. However, BIC did report some of its transportation statistics. 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. Polystyrene is not biodegradable and takes hundreds of years to break down. If you count the actual razor cover (if you haven't lost it long ago) then it will be four pieces for recycling. Life-cycle assessment stages 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. E.P.A. J Environ Assess Policy Manage 2000;2:45376, 2.

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. 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 . 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. The materials used in the production of disposable razors are limited due to the products simplicity however, many of the materials are unsustainable in that they are not biodegradable or easily recyclable, and require heavy energy input to manufacture. Whereas transportation has a relatively significant GHG impact for the disposable LMAs, by comparison the transportation of reusable LMAs has little impact on GHG emissions, because 40 disposable LMAs must be shipped to provide an equivalent function to 1 reusable LMA. It is cheap and highly versatile, and can either be hard plastic material, or a soft foam material, making it one of the most common plastic materials manufactured and used (What Is Polystyrene? Gathering all the data for the LCA is the most difficult part of the task, and normally assumptions have to be made where its impossible to gather all the knowledge required, thus not all the relevant impacts are considered. Marine cargo ships use a fuel called heavy fuel oil which produces around 145,000 BTU per gallon (Energy Consumption by Mode of Transportation.). Anesth Analg 2012;114:105566, 8. Interpretation of results The last step in the process is to interpret the results and compare them against each other. Once the plastic has cooled, the pieces are released from the moulds. Siddle, Dave. Introduction Paper diapers are roughly divided into two types: those for infants and those for adults. The actual making of the razors, and printing paper for their packaging has a lower environmental impact, than the waste from the factories high energy use. Gillette Plastic Disposable Shaving Kit supermax, for Hotel. 11 / Piece. The Bic USAs company website provides information about the making of the razors in the factories, regarding their inspection and factory standards, yet there is no mention for the environmental impact of the disposal. It is used in razor manufacturing mainly due to its high heat and water resistance, making it ideal for the conditions the product is used in. At an average of 10 reuse cycles, GHG impacts increase by >50%, and this is the break-even point at which the GHG emissions from reusable and disposable LMAs are essentially equal. In this section we also need to state the assumptions made during the process: An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). Everything You Need To Know About Polystyrene (PS).Everything You Need To Know About Polystyrene (PS), www.creativemechanisms.com/blog/polystyrene-ps-plastic. Next, the razors will be tested for flaws, strength, and razor hardness and sharpness (Safety Razor, madehow.com). Anesth Analg 1993;77:1079, 21. Once extracted, the tungsten is then shipped to a desired location for it to be manufactured into the metal compound. Land transport like trains and trucks use diesel as fuel and that produced 138,700 BTU (Energy Consumption by Mode of Transportation.). Ask a worker if you can put them in the bin by themselves or if they need to be in a recyclable container to protect sanitation workers from being cut. On the other hand, extending the number of uses to 80 (doubling the lifetime) reduces GHG emissions by 9%. LCAs can be used comparatively to assess different product or service design options or to identify environmental .
