Finally, the razors are packaged in cardboard and plastic, and shipped out to stores and markets globally for customers to purchase and use. . 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. Complete with an ergonomic shaped non-slip rubber handle for great control and maneuverability and easy rinse blades for 100% better rinsing (vs . 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). Safety Razor.How Products Are Made, www.madehow.com/Volume-5/Safety-Razor.html. After the plastic body is manufactured it goes through inspections similar to ones the blades go through. Disposable razors are a product that can be found in almost any average bathroom. 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. The cartridge-based razor had a slightly higher impact due to the rubber parts which cant be separated from the plastic body. The cheap price of the razor does not reflect the high cost of its waste and impact on the environment. Ecoinvent 2.2. After reaching the end of their useful lives, both LMAs and their respective packages entered waste management, which was modeled using US average statistics on recycling/composting, landfilling, and incineration.15 Although some incineration facilities also produce electricity, this credit is not included here. 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. The company urges users to mail packages over 15 lbs., in order to reduce the waste of mail as well, yet is not necessary. 13, 14 There are few published life cycle assessment studies of medical items (ref. Poly(Phenylene Oxide). The Polymer Science Learning Center, www.pslc.ws/macrog/ppo.htm. Two Life Cycle Impact Assessment (LCIA) methodologies were employed using SimaPro software 51,52 to calculate the environmental impacts of manufacturing both the plastic and compostable coffee . The metal is then heated and then cooled slowly to remove any internal stress, which makes it tougher, this process is called annealing (Safety Razor). The metal liquid then goes through a strengthening process called annealing. The plastic, however stable for the user, remains stable long after it is thrown away as well. Packaging is an . In the case of the disposable razor however, it is fairly simple due to its nature. Washington, DC: U.S. Environmental Protection Agency, 2000 rev, 25. Anaesthesia 2007;62:3814, 5. van Zundert AAJ, Fonck K, Al-Shaikh B, Mortier E. Comparison of the LMA-Classic with the new disposable soft seal laryngeal mask in spontaneously breathing adult patients. 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. These containers, mainly wooden pallets and spools, are subject to European legislat Manufacturing Processes (RAZOR): KAI FACTORY: KAI Group. KAI FACTORY | KAI Group, www.kai-group.com/global/en/kai-factory/process/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. `""(w 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). Disposable razors are a product that can be found in almost any average bathroom. A SYSTEMATIC METHODOLOGY FOR ACCURATE DESIGN-STAGE ESTIMATION OF ENERGY CONSUMPTION FOR INJECTION MOLDED PARTS. Since then, around 60 billion razors have been produced, distributed, and sold worldwide. 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. This is done on an assembly line by the robotic arm the inserts the razor blade into the small crevices in the plastic body. 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. 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. Weissman, Alexander, et al. Composition Assumptions for Disposable and Reusable Largyngeal Mask Airways (LMAs). Though technicians are paid regardless of whether they are cleaning LMAs or are performing some other task, these wages are nonetheless assigned to the reusable LMA on the basis of time spent. Di(2-ethylhexyl) phthalate (DEHP) Hazard Summary. The stability of the plastic components, while necessary for shelf stability and use, takes longer than one persons life-span to decompose. The blades are then carefully sharpened to create the razor blades. The remaining percentage is split up between energy consumption in their three facilities in: Clichy (France), Shelton (U.S.), and Cajamar (Brazil) (For You For Everyone: Registration Document, Bic). In this case its much harder for me to carry out an LCA on a Gillette razor than if Gillette did the LCA themselves, as they would have all the correct info required first-hand (reducing the number of assumptions needing to be used). A life-cycle inventory of cloth and disposable diapers was conducted based on diapering habits in Canada The parameters evaluated were energy consumption, water consumption, raw materials 15 Crop water use and water use efficiency on irrigated cotton farms in Australia S. Tennakoon, S. Milroy Environmental Science 2003 93 The Eco-Indicator method is a tool developed to help designers conduct a simplified LCA study. Such an analysis is commonly performed using life cycle assessment. American Society of Anesthesiologists (ASA) Task Force on Infection Control. A major flaw in the disposable razors design is in fact its inability to be sustainably and properly disposed, despite what its name suggests. The metal is heated to a temperature of 1967-2048 degrees Fahrenheit and tungsten carbide has a specific heat of 0.226 BTU/lb/Fahrenheit (Safety razor). Manufacturing Processes (RAZOR): KAI FACTORY: KAI Group.KAI FACTORY | KAI Group, www.kai-group.com/global/en/kai-factory/process/razor/. 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. Bic Disposable Razor (1975). Plastics News Europe, 19 Nov. 2009, www.plasticsnewseurope.com/article/20091119/PNE/311199986/bic-disposable-razor-1975. 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. All of which provides an easy user experience, but, takes a toll on the planet. In this paper, many details about the life cycle stages were not included. A combination of transportation methods is used depending on where the product needs to go. 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. Sensitivity and simple life cycle cost analyses were conducted to aid in interpretation of the results. Overcash M. Comparison of reusable and disposable medical textiles. Innovative and strategic advisor to leading philanthropies, corporates, governments, international institutions and NGOs. At 20 reuse cycles,16 the results indicate an increase in emissions of nearly 20%. Please enable scripts and reload this page. 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. Wages are then spent on food, entertainment, transport, and other economic activities that themselves have environmental impacts. to maintaining your privacy and will not share your personal information without Each year in Italy, millions of tons of fruits and vegetables are harvested, packed and transported to national and foreign retail outlets. Resources, Conservation & Recycling 156 (2020) 104704. 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. It is a thermoplastic that exhibits high heat resistance, dimensional stability, and accuracy and is often combined with other plastics, such as polystyrene, due to various problems in its processing (Poly(p-Phenylene Oxide, Wikipedia.org). qILL@#nO @8 BIC reported that the weight of one of their most popular disposable razors is 8.8 grams (Shavers). Reusable LMA cleaning was observed to proceed as follows. E.P.A. B|$5 This study assumed no difference between the devices in terms of clinical efficacy or time for placement.4 Disposable LMAs were discarded in regular municipal solid waste bins after use. Interpretation of results The last step in the process is to interpret the results and compare them against each other. In the late 1990s, disposable LMAs became available. In order to carry out the Eco-Indicator analysis method, the methodology described below has to be followed: GaBi is a LCA software that allows its users to connect environmental impacts to a product across its lifespan. Disposable and reusable LMAs typically differ in material composition, packaging, reuse, and cost. They report their waste production being at 340 tons, which represented an increase of 22% from 2015 (Bic). mmw*vA|5v*3n9IUt){e%!HN6@` xcr@pz*Fbiq%1!TJ-CF*1OS|UZU\vQL7M?m'b-,r~S}Y&/{#U6U)S|%q[RB !3j~tj$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> 8 John Adam Street hbbd``b`z$k@D However, the viability of the disposable razor is always thrown into question because of the sheer amount of resources that it expends. Several waste management scenarios were also considered, including 100% landfilling and 100% incineration, because practices are highly location dependent. Lv, Andrea Lind, and Tigist Fetene. The study found that: Reusable LMAs were collected in a dirty device bin on the anesthesia cart and then reprocessed by the anesthesia technicians. 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). But what really goes into making one of these seemingly mundane disposable razors and what happens to it after its tossed in the trash? After the end of their recommended lifetime, reusable LMAs were also placed in municipal solid waste containers. There are only two components for the BIC disposable razors which are the plastic body and razor blade. 2. The Nation's Freight: U.S. Bureau of Transportation Statistics. 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%). You may be trying to access this site from a secured browser on the server. 3.Quantify the materials and processes 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? Cited Here. American Medical Association (AMA). The majority of life cycle human health impacts of disposable LMAs are caused by PVC use in packaging and the device itself. Health care facilities can decrease their environmental impacts by using reusable LMAs, to a lesser extent by selecting disposable LMA models that are not made of certain plastics, and by ordering in bulk from local distributors. Life Cycle Assessment (LCA) measures the impact of products on the environment. To compile a detailed life cycle inventory of the environmental burdens Manufacturers can do this solely by machine or by human eye/hand plus machine for extra quality assurance. Anesthesia & Analgesia114(5):1067-1072, May 2012. 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. 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. Chain Management by Life Cycle Assessment (CMLCA) software has been used to conduct the LCA and Ecoinvent 2.01 has been used for life cycle inventory data. 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. a 4.1% (Bic). The more capital-intensive option of increasing the energy efficiency of the autoclave machines by 10% decreases GHG emissions by 8%. The metal is not yet to its final form, as it is still greatly held together by the previously added binders. associated with the environmental interventions attributable to the life-cycle of a product. Subramaniar Trading Company. The human-health-related impact categories are pertinent to those developing standards for the delivery of health care. Razor blades dull quickly after repeated use, and are recommended to be used only three to ten times, making them a cheap alternative to reusable cartridges. 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. 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. The powder is then shaped, usually by the process of die stamping. These benefits must be weighed against concerns regarding transmission of infection. The next step in the process is the assembly of all the parts. The metal that can be used in the cartridge is also cut out during this stage. LCA is a standardized, science-based tool for quantifying the impact in order to assess lifetime environmental impact. For You For Everyone: Registration Document.Bic World, Bic, 2016, www.bicworld.com/sites/default/files/2017-03/BIC_DRF2016_EN.pdf. 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. your express consent. There is also an additional resin called fluorine resin that is applied to the blades, which allows them to freely glide on the skin. This LCA is specific for surgical gowns used in the Twin Cities of Minneapolis and St Paul, Minnesota. 39 ($0.37/Count) FREE delivery Thu, Mar 2 on $25 of items shipped by Amazon. It can be used to study the environmental impact of either a product or the function the product is designed to perform. Individually autoclaving the reusable LMA (because of stock shortages, for example) increased life cycle GHG emissions by >400%, whereas loading with 10 LMAs per cycle decreased emissions by nearly 25%. 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. 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). It has been assumed that the packaging contains cardboard, even though it has been made from other natural fibres like bamboo, as there is no info on those materials in the Eco-Indicator tables. 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. 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. Highlights U.S. Environmental Protection Agency. Dbendorf, Switzerland, 2011, 12. How Long Will It Take That Bag of Trash to Decompose in a Landfill?The Balance Small Business, The Balance Small Business, 22 Oct. 2019, www.thebalancesmb.com/how-long-does-it-take-garbage-to-decompose-2878033#plastic-waste. 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. By raising awareness and creating locations where one can drop off used razors for recycling, perhaps a change can come. 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. Life Cycle Assessment of Disposable and Reusable Nappies in the UK Ref: ISBN 1844324273, LIT 2080 PDF, 1.83 MB, 203 pages This file may not be suitable for users of assistive technology.. This project is a collaboration between the Great Recovery Programme and Fab Lab London. LeBlanc, Rick. a Centers for Disease Control. Chu L, Mathur P, Trudell J, Brock-Utne J. "Tungsten Processing." endstream endobj startxref To begin the process of creating the metal, the tungsten is purified and ground into a fine powder. Available at: http://www.cdc.gov/ncidod/dvrd/cjd/qa_cjd_infection_control.htm. 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. An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). 5.Interpret and analyse the results. 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). @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 . Each manufacturing plant or node in the supply chain is referred to as agate-to-gate (GTG) life cycle inventory. Plastics are cleaned and pelletized to be recycled into new products, such as picnic tables and park benches. Marvel Product Razor Lady Body Shaver Disposable Razore. The Bic corporation considers their environmental impact and takes steps to reduce as much waste as possible. The authors declare no conflict of interest. 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. During the research, I could not find how much energy BIC injection molding machines use, but I did find the energy usage of a common injection molding machine called the Babyplast. This obviously makes the results less accurate, but it can still be used as a general indicator of impact. Siddle, Dave. The indirect emissions were mostly from the electricity use in the factories. Terracycle. Anesth Analg 1998;87:921, 3. 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. 1. Life Cycle Assessment (LCA) is a widely-used technique to comprehensively assess the impacts of a product or a process on the environment and acts as an effective tool in gauging the. Manufacturer specifications indicate 20 kWh of electricity use for a 5-minute cycle at 135C. The metal and plastic components of the cartridges will be assembled, where they will then go to the next station where the blades will be inserted. The metal used for the razor blades is called Tungsten Carbide which is used in wear applications, such as shaving (Safety Razor). Sherman JD, Ryan S. Ecological responsibility in anesthesia practice. Steel Life Cycle.SSAB, www.ssab.com/company/sustainability/sustainable-offering/steel-life-cycle?di=discover21C927E58ECC41198B78D915F7E3E2AF. 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. In conclusion, disposable razors are being used and thrown away at a rate that is unsustainable for the finite space on the planet. 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). 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. h[K#1}\$u@ The largest source of GHG emissions for the disposable LMAs (23%) is the production and polymerization of PVC, the main material constituent. Redesigning the Razor Life Cycle Assessment.The Great Recovery, www.greatrecovery.org.uk/resources/3682/. To start the process of making the blades, tungsten carbide is melted at high temperatures. 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). 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. For both environmental and cost considerations, management and operating procedures should be put in place to ensure that reusable LMAs are not discarded prematurely. Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. The next step the blade goes through is called polishing in which is done using strops made out of cowhide to get the desired blade edge shape, the blade is then cut into the sizes of the individual blades, which are then sent off to be inspected.
