Sustainability | Free Full-Text | Life Cycle Assessments of Takeaway 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. Safety Razor. How Products Are Made, www.madehow.com/Volume-5/Safety-Razor.html. The human-health-related impact categories are pertinent to those developing standards for the delivery of health care. disposable paper diaper; material recycling; closed-loop recycling; life cycle assessment (LCA) 1. 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). The results also suggest effective procurement strategies for reducing the impacts of disposable LMAs where they are selected. hbbd``b`z$k@D (iii)What are the strategic lifecycle challenges for paramount's current products as well as for clean edge? Additionally, the PVC-dominated material composition of the disposable LMA and associated packaging added significantly to its impacts. 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. Ann Fr Anesth Reanim 2006;25:8114, 7. The blades are then carefully sharpened to create the razor blades. Tungsten carbide is a carbide compound, made up of equal parts of tungsten and carbon. 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.

They are resins that maintain a high dimensional stability, which helps create fast and cheap plastic razor handles (Safety Razor). Amazon Best Sellers: Best Men's Disposable Shaving Razors Everything You Need To Know About Polystyrene (PS).Everything You Need To Know About Polystyrene (PS), www.creativemechanisms.com/blog/polystyrene-ps-plastic. Being that it is such a common and quickly replaced product, this is is a major issue in terms of waste. The body of both razors had similar impact as their weights were also quite similar. Research and Innovative Technology Administration. Phoenix: IEEE, 2008, 23. 6,474. By far, the biggest impact during the manufacturing of the razors was the 17 spot welds done in each cartridge. 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. The metal is not yet to its final form, as it is still greatly held together by the previously added binders. 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. Life Cycle Assessment: Disposable paper cups by Shanice Robbins Considering human health concerns, the majority (60%) of impacts for the disposable LMA is due to the production of polymers, PVC in particular, with emissions from incineration contributing another 15%. 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. 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. Contribution: This author helped design the study and prepare the manuscript. BIC Disposable Razor Design Life-Cycle Terracycle. It has a low density and is quite flexible and heat resistant, therefore making it an easily moulded and extruded material. U.S. Environmental Protection Agency. The specific type or blend of plastic for BIC razors is used is called polystyrene (Europe). After the plastic body is manufactured it goes through inspections similar to ones the blades go through. Comparative life cycle assessment of disposable and reusable - PubMed 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. Click the image for pricing & more info. 13, 14 There are few published life cycle assessment studies of medical items (ref. 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.). Disposable razors are a product that can be found in almost any average bathroom. Contribution: This author helped conduct the study and analyze the data. Sustainable Development at BIC . 6 Jan. 2011. Nash, Nathaniel C. HOW BIC LOST THE EDGE TO GILLETTE. The New York Times, The New York Times, 11 Apr. You Asked, We Answered. Chronicle, 12 June 2015, chronicle.kennametal.com/what-is-tungsten-carbide-you-asked-we-answered/. In this life cycle breakdown, I will be discussing what materials go into the making of disposable razors and what processes the materials go through in the operation of making a disposable razor. 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. However, we can discuss the energy usage of different modes of transportation. 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. Production of razor blades across the industry is fairly standard. BIC currently holds around 11 percent market share in disposable razors (Nash). For You For Everyone: Registration Document.Bic World, Bic, 2016, www.bicworld.com/sites/default/files/2017-03/BIC_DRF2016_EN.pdf. Brimacombe J, Keller C, Morris R, Mecklem D. A comparison of the disposable versus the reusable laryngeal mask airway in paralyzed adult patients. These are the reasons why I will carry out an Eco-Indicator Assessment instead of a full LCA. In this case its the life-cycle of the cartridge-based razor. 11 / Piece. Williams S, Henderson K. A survey into the number of times laryngeal masks are used. The EPA has now stopped tracking the: impact of disposable razors on the environment and has no update on the figure (Olsen). Life Cycle Assessment (LCA) is a modeling tool for quantifying the environmental impacts of products and processes. Sustainable Development Report. 2019, science.howstuffworks.com/environmental/green-science/polystyrene-recycling.htm. This liquid material is then injected into moulds, or extruded through moulds, where it will cool and take the form of the desired cartridge and handle shape. The original LMA was a reusable device (Intavent International SA, Henley-on-Thames, UK). Erosion time for the blades was difficult to find, yet tungsten steel does erode faster than the plastic elements to the disposable razor due to the carbon alloys brittle makeup. 769 0 obj <>stream CASE STUDY ANALYSIS - CLEAN EDGE, NON DISPOSABLE RAZOR Q1. We performed a life cycle assessment of 2 analogous LMAs, the disposable LMA Unique and the reusable LMA Classic, according to internationally accepted standard life cycle assessment methods (ISO 14040: 2006). There are three main components in a disposable razor. 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. 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. The autoclave was typically run with 5 LMAs, although loading varied significantly. From the *Department of Civil and Environmental Engineering, College of Engineering, Northeastern University, Boston, MA; School of Forestry and Environmental Studies, Yale University, New Haven, CT; Department of Anesthesiology, Yale School of Medicine/YaleNew Haven Hospital, New Haven, CT. Funding: Department of Anesthesiology, Yale School of Medicine. Our LCA team retains its reputation as the most experienced life cycle staff in North America. 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. Life Cycle Assessment of the Closed-Loop Recycling of Used Disposable 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. Subramaniar Trading Company. Bic has attempted to lower their direct emissions by having factories world-wide and creating: a Transport Community which connects shipping managers on each continent to raise control for greenhouse gas emissions, optimize shipments and routes, and use only responsible carriers (Bic). J Clin Anesth 1997;9:432, 20. How Is Tungsten Carbide Formed? Chronicle, 20 Aug. 2015, chronicle.kennametal.com/how-is-tungsten-carbide-formed/. The Nation's Freight: U.S. Bureau of Transportation Statistics. 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. Europe, Plastic News. Phenylene oxide, or PPO, is another common plastic material used in disposable razors. The metal used for the razor blades is called Tungsten Carbide which is used in wear applications, such as shaving (Safety Razor). Overall BIC is an industry leader when it comes to reducing the environmental impact that their disposable products make. Int Anesthesiol Clin 2010;48:139, 24. There are so many variables that you have to take into account when calculating how much of an impact a product is having on the environment and our resources. Several clinical trials comparing function and ease of placement demonstrated no significant difference between disposable and reusable versions,25 allowing hospitals to base purchase decisions on economic considerations alone. 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/. Differences in environmental impacts between devices may present a compelling consideration in their selection. Properly following the instructions it should (hopefully) leave you with three pieces, the handle, the metal blade, the plastic that was covering the blade. B|$5 The data collected through LCA helps organizations make conscious decisions that affect the environment. Life cycle assessment (LCA) is a method used to estimate the total environmental impacts from producing a good or service. a Centers for Disease Control. Another advantage is that the process produces a single score (Eco-Indicator Point) for the all the impacts of the product, not just individual ones for each part. 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. Life Cycle Assessment (LCA): A Guide to Best Practice - ResearchGate Amazon.com: Bulk Disposable Razors There are some solutions and new recycling ideas, yet, the reduction of waste for disposable razors is still far off. The Potential of Polypropylene.Recycling Today, Recycling Today, 17 July 2019, www.recyclingtoday.com/article/the-recycling-potential-of-polypropylene/.

Please try after some time. Life of a Razor Blade - GreatRazors.com 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. The 2 LMA options are nearly equivalent in terms of eutrophication impacts, but with different contributions. A 2005 analysis published by U.K. Due to the nature of the disposable razor, they are usually just thrown in the trash and sent off to a landfill. This is known as a Life Cycle Inventory (LCI) This can be extremely complex because it can involve dozens of separate processes, as well as hundreds of tracked substances. What's the greenest way to shave? - Slate Magazine Address correspondence to Jodi Sherman, MD, Yale University, School of Medicine, Department of Anesthesiology, 333 Cedar Street, TMP3, New Haven, CT 06520. 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. 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 shown through their commitment to their eco-design process and new recycling programs that are undergoing testing. 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 Fabricators, 18 July 2018, www.thefabricator.com/thefabricator/article/stamping/die-basics-101-intro-to-stamping. Each time the steam autoclave machine conducts a sterilizing cycle, a large amount of energy is used to heat the steam. Atlanta, 2012. Life Cycle Assessment (LCA) explained - PR Sustainability Data is temporarily unavailable. 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. Flying staff to meetings, shipping, and distributing the product is the highest offender for the planet. An exact number for the energy use for BIC was not obtained. The razors are mainly made of plastic, so they will be decomposing at a very slow rate in the landfill. Life Cycle Assessment of Reusable and Disposable Cleanroom Coveralls . It all starts with the melting and combining of the desired metal. At every point during planning, production, and even marketing, the quantity of consumption should be analyzed to adjust business models accordingly. Impact Assessment. But this is expected from a large brand like Gillette. Life cycle assessment, according to ISO 14040/44, is conducted in four steps [29,30,31]: (1) goal and scope definition, (2) life cycle inventory, (3) life cycle impact assessment, and (4) interpretation. to maintaining your privacy and will not share your personal information without 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. An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). Choosing a less-green disposable will magnify your razor's manufacturing impact, but it won't change the overall picture very much. Staff, RT. The Bic corporation considers their environmental impact and takes steps to reduce as much waste as possible. The largest sources of both cancer and noncancer impacts for the reusable LMA are from emissions from waste management (35%), the mining and production of metals to build wastewater treatment infrastructure (25%), and the bleaching of packaging paper and the card insert (20%). Redesigning the Razor Life Cycle Assessment.The Great Recovery, www.greatrecovery.org.uk/resources/3682/.

The number of BIC razors that are used by consumers is astounding. endstream endobj 752 0 obj <>stream The Editors of Encyclopaedia Britannica. No such cases have been reported since 1976.a There is no reported case of iatrogenic infection of any type linked to a reusable LMA. The blade is made from a tungsten steel, and carbon alloy. 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. DEHP is a plasticizer routinely added to impart flexibility to PVC-based products, such as IV bags, tubing, and endotracheal tubes. Poly(Phenylene Oxide). The Polymer Science Learning Center, www.pslc.ws/macrog/ppo.htm. 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. 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. 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 Using Life Cycle Assessments to Understand Cloth vs. Disposables - BAHP 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 . 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. WC2N 6EZ, Redesigning the razor Life Cycle Assessment. 2.Define the life-cycle Facilities that select reusable devices should implement inventory and operating procedures that ensure that devices are reused to the greatest possible extent. Gillette Mach3 Men's Disposable Razor for Sensitive Skin - Best Cartridge Razor for Sensitive Skin. However, the viability of the disposable razor is always thrown into question because of the sheer amount of resources that it expends. After that, the metal is pressed down to the desired blade thickness which is around 1mm (Manufacturing Processes). GaBi includes its own database containing life cycle inventories of processes such as polypropylene manufacturing, transportation, and landfill . 2. 2. This means that it takes around 1 BTU to heat a 0.035-ounce razor blade to the desired temperature (Julabo et.al). Reusable LMAs were collected in a dirty device bin on the anesthesia cart and then reprocessed by the anesthesia technicians. Sinha R, Sunder R. Retiring reusable laryngeal mask airways after 40: an anaesthetist's dilemma. (i)What changes occurring in non-disposable Razor category? The indirect emissions were mostly from the electricity use in the factories. 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. Once the plastic has cooled, the pieces are released from the moulds. The full life cycle environmental impacts can be challenging to model, because modern production "pathways" can involve numerous interacting technologies, each of which can consume materials and energy that are themselves products of complex production processes. The life of a typical razor blade is not an easy one. xTkJ((5:Ome\%{yIlka;K=1 Such an analysis is commonly performed using life cycle assessment. Approximately 24 L/min of water are used by the autoclave for cooling, for a total of 960 L of water needed to sterilize an LMA 40 times. 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. Each year in Italy, millions of tons of fruits and vegetables are harvested, packed and transported to national and foreign retail outlets. 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). All that is needed is the insertion of the razor blade into the plastic body. use/disposable and multiple-use/washable surgical gowns. 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. Applying this method of assessment is complex and difficult and translating the theory into a . Despite the overall lower impacts of the reusable LMA, there are still several ways that its environmental profile could be improved, as suggested by the results shown in Table 2. @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 . BIC has noted however that they strive to be as efficient with materials used when it comes to their packaging. Since BICs products do not go to a single location it is impossible to give an exact number for BICs energy usage in transportation. 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). The total amount of indirect emissions was 89,762 tonnes of carbon dioxide (For You For Everyone Registration Document). In this paper, many details about the life cycle stages were not included. It is used to assist companies, consumers, and policy-makers in greening their practices and decisions. Packaging is an . We perform Life Cycle Assessments (LCA) and Critical Reviews in accordance with ISO 14040/44 for products and services. All of which provides an easy user experience, but, takes a toll on the planet. 3.Quantify the materials and processes There is uncertainty in several model assumptions. 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. International Sympsium on Sustainable Systems and Technology. 3. Disposable razors are designed for consumers that prefer minimum spending . Life Cycle Assessment - an overview | ScienceDirect Topics Overall, reusable LMAs were found to have fewer negative environmental effects in nearly all categories, typically contributing <50% of the impacts of disposable LMAs. Tungsten is a natural metal deposit that is found in metamorphic, and granitic igneous rocks, primarily in China, Russia, South Korea, South America, and the Rocky Mountains in the United States. 1. BIC is voicing their concern about the environmental impact that their large production goals can have. Composition Assumptions for Disposable and Reusable Largyngeal Mask Airways (LMAs).
