In this case its the life-cycle of the cartridge-based razor. 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. LCA's are completed particularly in relation to how to develop a sustainable world where less waste and more reuse is implemented. You may be trying to access this site from a secured browser on the server. Production of razor blades across the industry is fairly standard. Encyclopaedia Brittanica, Encyclopaedia Brittanica, Inc., 26 Sept. 2012, www.britannica.com/technology/tungsten-processing#ref82029. 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. Park Ridge, IL: American Society of Anesthesiologists, 1999, 15. Life Cycle Assessment of a Building | Sphera 2. your express consent. A major flaw in the disposable razors design is in fact its inability to be sustainably and properly disposed, despite what its name suggests. 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. Marvel Product Razor Lady Body Shaver Disposable Razore. 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. 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. 3 in Table 1). We perform Life Cycle Assessments (LCA) and Critical Reviews in accordance with ISO 14040/44 for products and services. J Clin Anesth 1997;9:432, 20. For more information, please refer to our Privacy Policy. 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). American Society of Anesthesiologists (ASA) Task Force on Infection Control. 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. 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. 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. The number of BIC razors that are used by consumers is astounding. Another material used is polystyrene. 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. 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. 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. 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. 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. (iii)What are the strategic lifecycle challenges for paramount's current products as well as for clean edge? A Life Cycle Assessment of Disposable Razors. "Tungsten Processing." Life Cycle Assessment explained: an introduction to building LCA LeBlanc, Rick. These containers, mainly wooden pallets and spools, are subject to European legislat LMA North America. The total amount of indirect emissions was 89,762 tonnes of carbon dioxide (For You For Everyone Registration Document). Facilities that select reusable devices should implement inventory and operating procedures that ensure that devices are reused to the greatest possible extent. The Editors of Encyclopaedia Britannica. Gillette Sensor3 Sensitive Men's Disposable Razors : Target 11,772. 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. Life Cycle Assessment Explained - STiCH In their study of Life cycle assessment of wastewater treatment technologies treating petroleum process waters, Vlaopolous et al. 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 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. LCA can be used to compare alternative products, processes or services; compare alternative life cycles for a certain product . 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. From mining and extracting the natural tungsten metal, to making the metal alloy and manufacturing just the blade, waste is released. This means that it takes around 1 BTU to heat a 0.035-ounce razor blade to the desired temperature (Julabo et.al). It takes a lifetime perspective LCA takes into consideration all the steps that lead from raw material through manufacture, distribution and usage to final disposal. Polyphenylene Oxides.Polyphenylene Oxides - an Overview | ScienceDirect Topics, 2013, www.sciencedirect.com/topics/chemical-engineering/polyphenylene-oxides. 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 . PDF A Comparative Life Cycle Assessment of Compostable and Reusable Takeout BIC has repeatedly come under fire because of the environmental impact their disposable razors have, due to the sheer amount of their disposable products are used every year. BIC Comfort 3 Refillable Three-Blade Disposable Razors for Men, Sensitive Skin Razor for a Comfortable Shave, 1 Handle and 12 Cartridges With 3 Blades, 13 Piece Razor Kit. The fewer LMAs placed in the autoclave, the larger the impacts on GHG emissions and global warming on each individual unit. The Eco-Indicator for EPDM rubber includes the manufacturing of the rubber as well as the molding process. B|$5 10 Best Disposable Razors for Men (Incl. Cartridge) - 2023 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). Data Uncertainty. 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.9 Data collection was specific to Yale New Haven Hospital, including device transportation, cleaning procedures and labor, energy requirements, and disposal. These benefits must be weighed against concerns regarding transmission of infection. Life Cycle Assessment (LCA) is a modeling tool for quantifying the environmental impacts of products and processes. Wang, Chun Tsin, and Alexander Sutulor. Contribution: This author helped design the study, analyze the data, and prepare the manuscript. There is uncertainty in several model assumptions. The natural half life of a large stock of reusable laryngeal mask airways at a teaching hospital. Life cycle assessment - Universitetet i Agder Biro P. Damage to laryngeal masks during sterilization. CASE STUDY ANALYSIS - CLEAN EDGE, NON DISPOSABLE RAZOR Q1. Once in the landfill, it usually takes around 20-30 years to breakdown. Anesth Analg 1993;77:1079, 21. However, BIC did report some of its transportation statistics. With such a fast accumulating waste and slow decomposition rate, there must be changes and incentive for companies to rethink the disposable 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 differences in environmental impacts between these devices may present a compelling consideration in device selection when concern for infection transmission is not a factor. There are some solutions and new recycling ideas, yet, the reduction of waste for disposable razors is still far off. In addition, the impact categories of eutrophication (growth of microorganisms due to excess nutrients) and terrestrial ecotoxicity reflect the impacts on other species and ecosystems and have implications for public health. PurposeIn this study, a life cycle assessment of a bioplastic based diaper was performed. The Ramboll Life Cycle Assessment (LCA) found that, assuming realistic usage over a year, the energy consumption involved in the use phase of reusable plastic and traditional crockery, during in-store or out-sourced washing and drying, outweighed the environmental impact of single-use paper dishes. 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. associated with the environmental interventions attributable to the life-cycle of a product. Main methodological choices . 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 Plastics Europe 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. Research and Innovative Technology Administration. 769 0 obj <>stream Complete with an ergonomic shaped non-slip rubber handle for great control and maneuverability and easy rinse blades for 100% better rinsing (vs . It is used to assist companies, consumers, and policy-makers in greening their practices and decisions. 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. 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). It can be used to study the environmental impact of either a product or the function the product is designed to perform. 1. To begin the process of making tungsten carbide, the tungsten must first be extracted. 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). Bic Disposable Razor (1975). Plastics News Europe, 19 Nov. 2009, www.plasticsnewseurope.com/article/20091119/PNE/311199986/bic-disposable-razor-1975. GaBi includes its own database containing life cycle inventories of processes such as polypropylene manufacturing, transportation, and landfill . The life of a typical razor blade is not an easy one. The results also suggest effective procurement strategies for reducing the impacts of disposable LMAs where they are selected. 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. There are only two components for the BIC disposable razors which are the plastic body and razor blade. Wolters Kluwer Health Disposable LMAs are made largely from PVC plastic, which is associated with a number of health concerns that are gaining increased attention.23 Historic efforts to minimize routine medical incineration resulted in the 1998 Memorandum of Understanding between the American Hospital Association and the US Environmental Protection Agency, largely on the basis of recognition of the potential carcinogenic effects of burning PVC plastics. In conclusion, disposable razors are being used and thrown away at a rate that is unsustainable for the finite space on the planet. The tables didnt contain values for welding steel, so it has been assumed that the value is close to welding aluminium which is in the table. 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. Saudi J Anaesth 2008;2:58. Manufacturers can do this solely by machine or by human eye/hand plus machine for extra quality assurance. Waste is not only a problem when a product is disposed of, but also when it is initially manufactured. LCA is the most common tool for quantifying the environmental effects associated with a product, process, or service's entire life (Baumann and Tillman 2004).LCA was performed in accordance with the international standards of the ISO 14040 and ISO 14044 . Sustainability | Free Full-Text | Reducing the Environmental Impact of This LCA is specific for surgical gowns used in the Twin Cities of Minneapolis and St Paul, Minnesota. What Is Tungsten Carbide?" Swiss Center for Life Cycle Inventories. In BIC factories they pride themselves in producing a quality product, so the blades go through a series of highly precise visual inspections with cameras which help with rejecting blades that do not meet BIC standards (Case Studies) After that they go through visual inspection is done be BIC employees to reject any blades that the cameras were not rejected by the inspection camera system, the blades are then send off to be coated and burned. There is no public data entailing the details of this plastics recyclability. Each manufacturing plant or node in the supply chain is referred to as agate-to-gate (GTG) life cycle inventory. to maintaining your privacy and will not share your personal information without 3. Sinha R, Sunder R. Retiring reusable laryngeal mask airways after 40: an anaesthetist's dilemma. Marinella Levi. And then there's the water. Life-cycle assessment (LCA) is a process of evaluating the effects that a product has on the environment over the entire period of its life thereby increasing resource-use efficiency and decreasing liabilities. During shaving, the sharp edges of the blade will chip off at a slow but steady rate, dulling the blade after repeated shavings. 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. Using BEES to select cost-effective green products. Life cycle assessment of a disposable and a reusable surgery instrument Due to the nature of the disposable razor, they are usually just thrown in the trash and sent off to a landfill. Yet, tungsten has been found to deposit particles into the soil that causes some contamination, making it a recent concern to the United States Environmental Protection Agency. What does a business area's assessment of agreements, income, and value implicate? The use of disposable razors is unsustainable with our growing population and increased demand. In the late 1990s, disposable LMAs became available. Redesigning the razor - Life Cycle Assessment - Great Recovery Life Cycle Assessment (LCA): A Guide to Best Practice - ResearchGate If the reusable LMA is discarded prematurely, e.g., after 20 uses,16 the unit cost increases to $13 per unit, but decreases to $5.50 if the lifetime can be extended to 80 uses. What IS Life Cycle Assessment? 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). 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.). #4. Properly following the instructions it should (hopefully) leave you with three pieces, the handle, the metal blade, the plastic that was covering the blade. International Sympsium on Sustainable Systems and Technology. However, the viability of the disposable razor is always thrown into question because of the sheer amount of resources that it expends. Ison E, Miller A. 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.). Julabo Gmbh, et al. Dbendorf, Switzerland, 2011, 12. Everything You Need To Know About Polypropylene (PP) Plastic. Everything You Need To Know About Polypropylene (PP) Plastic, https://www.creativemechanisms.com/blog/all-about-polypropylene-pp-plastic. The cartridge-based razor had a slightly higher impact due to the rubber parts which cant be separated from the plastic body. This was a cradle-to-grave study that included inputs and outputs for the manufacture, transport, use, and waste phases of the LMAs. Paper diapers for infants, which are highly convenient as they do not require laundering like cloth diapers, are essential for daily life in Japan. Life Cycle Assessment and Costing Methods for Device - PubMed Once Terracycle has collected the waste, it is: broken down and separated by material. The Life Cycle Impact Assessment (LCIA) is where the impacts on the environment are calculated. life cycle assessment European Environment Agency 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. Life Cycle Analysis (LCA) - A Complete Guide to LCAs Contact Supplier. DEHP leaches out upon exposure to heat and lipids, as would be the case in contact with mucous membranes. 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. The main causes of the reusable LMA's environmental impacts are the steam used in the autoclave sterilizing machine and, to a lesser extent, the wastewater generated from washing the LMAs. However, it is fairly easy to find what the disposable razors components are made of, due to its simplicity. Safety Razor. How Products Are Made www.madehow.com/Volume-5/Safety-Razor.html. This is where the razors are portioned into their desired packaging amounts, that will be sent off to consumers. One of the materials used is polypropylene, a thermoplastic addition polymer made from the combination of propylene monomers (Creative Mechanisms Staff, creativemechanisms.com). The life cycle of plastics Life cycle assessment (LCA) considers the environmental aspects associated with a product over its lifespan. Life Cycle Impact Assessment is the estimation of indicators of the environmental pressures in terms of e.g. 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. BIC put out a report detailing how they deal with the waste from their factories. Life Cycle Assessments - Diaper Answers
