Each time the steam autoclave machine conducts a sterilizing cycle, a large amount of energy is used to heat the steam. Figueredo E. Changes in the intracuff pressure of the laryngeal masks airway caused by repeated use. Di(2-ethylhexyl) phthalate (DEHP) Hazard Summary. 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). These few simple materials go through processes of heating, cooling, moulding, cutting, and sharpening throughout their manufacturing process to eventually become the handle, razor blades, and blade cartridge, that will then be assembled to become a disposable razor.
Conducting a Life Cycle Assessment (LCA): from Theory to Practical Eshwar Shop. Pollution of the oceans from plastics has become an increasingly large issue that researchers are still assessing. 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). Main methodological choices . The human-health-related impact categories are pertinent to those developing standards for the delivery of health care. Disposable Razors in Bulk, Bulk Razors with Knife Caps, Individually Packaged Disposable Razors Bulk, Suitable for Hotels, Shelters, Homeless People, Nursing Homes, Charities, Churches (60) 4.2 4.2 out of 5 stars (9) $22.39 $ 22. BIC reported that every year around 2.6 billion of their razors are chosen by consumers every year (Shaver's). 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.
Gillette Sensor3 Sensitive Men's Disposable Razors : Target Each razor can last up to 12 gentle shaves. 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. Manufacturing Processes (RAZOR): KAI FACTORY: KAI Group.KAI FACTORY | KAI Group, www.kai-group.com/global/en/kai-factory/process/razor/. The body of both razors had similar impact as their weights were also quite similar.
Life Cycle Approach to Plastic Pollution - Life Cycle Initiative Direct emissions refer to any emissions that resulted from the burning of fossil fuels and Indirect emissions refer to any emissions that resulted from the generation of electricity. LCAs can be used comparatively to assess different product or service design options or to identify environmental . 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. Cargo planes and other transport aircraft use jet fuel which produces 135,000 BTU per gallon (Energy Consumption by Mode of Transportation.). 0
Chu L, Mathur P, Trudell J, Brock-Utne J. 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. In landfilling or incinerating this part, the large amount of energy and material value used in creating it is lost. An exact number for the energy use for BIC was not obtained. The blades and lubricating strip were too light to be measured with our equipment so their weights were rounded to 1g. The metal liquid then goes through a strengthening process called annealing. One of the materials used is polypropylene, a thermoplastic addition polymer made from the combination of propylene monomers (Creative Mechanisms Staff, creativemechanisms.com). I could however not find any details about the energy consumption of the machines used in the assembly process. 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. : Uses, Benefits, and Safety Facts. ChemicalSafetyFacts.org, 17 June 2019, www.chemicalsafetyfacts.org/polystyrene/. 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. A 2005 analysis published by U.K. Bic Disposable Razor (1975). Plastics News Europe, 19 Nov. 2009, www.plasticsnewseurope.com/article/20091119/PNE/311199986/bic-disposable-razor-1975. What Is Polystyrene? The aim of this paper is to analyse substitutes to disposable plastic tableware using the Life Cycle Assessment methodology. 4. In my research, I was not able to find specifics about where BIC sources their materials, I believe that this is due to them being a global company. Biro P. Damage to laryngeal masks during sterilization. Redesigning the Razor Life Cycle Assessment. The Great Recovery, http://www.greatrecovery.org.uk/resources/3682/. Any extra plastic will be discarded, remelted, and reused (Safety Razor, madehow.com). 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 was a cradle-to-grave study that included inputs and outputs for the manufacture, transport, use, and waste phases of the LMAs. The metal is then quenched in water to bring it to -76 to -112 degrees Fahrenheit to harden the material (Safety Razor). However, it is fairly easy to find what the disposable razors components are made of, due to its simplicity. 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. It has been assumed that the only part recycled at the end of life is the packaging.
Properly Recycle Your Disposable Razors | Leafygreen.info The natural half life of a large stock of reusable laryngeal mask airways at a teaching hospital. 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. There are many detailed stages but the main ones are: extracting and. Staff, RT. Overall, reusable LMAs were found to have fewer negative environmental effects in nearly all categories, typically contributing <50% of the impacts of disposable LMAs. During shaving, the sharp edges of the blade will chip off at a slow but steady rate, dulling the blade after repeated shavings. Life cycle analysis takes into account the following categories: Energy consumption Water consumption Air emissions (including carbon dioxide and other global warming gases) Water emissions Generation of solid waste 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. To aid in solving this issue, I believe consumers should stray away from wasteful disposable razors and be encouraged to go with more sustainable and longer lasting options such as classic safety razors. 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.). 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 Comparative Life Cycle Assessment of Disposable and Reusable Packaging for the Distribution of Italian Fruit and Vegetables. The indirect emissions were mostly from the electricity use in the factories.

This reflects the equivalence between 40 disposable LMAs and their associated materials, waste, and 40 uses of 1 reusable LMA. Comparison of the single use and reusable intubating laryngeal mask airway.
10 Best Disposable Razors for Men (Incl. Cartridge) - 2023 Life Cycle Assessment of Compostable Coffee Pods: A US - Nature Reprints will not be available from the authors. 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.
(PDF) Comparative life cycle analysis of disposable and reusable 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.
Comparative Life Cycle Assessment of Disposable and Reusable - LWW During production, two components have to be created which are the blade and the plastic body. Amersfoort, The Netherlands: Product Ecology (PR) Consultants, 2011, 11. 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?). It can be used to study the environmental impact of either a product or the function the product is designed to perform. 748 0 obj

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). Such an analysis is commonly performed using life cycle assessment. Environment Agency (Life Cycle Assessment of Disposable and Reusable Nappies in the U.K.) investigated the impact of three diapering systems: cloth diapers with home wash, cloth diapers with commercial laundry, and disposable diapers. 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. LCA is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service. 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. 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. Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2010. In their study of Life cycle assessment of wastewater treatment technologies treating petroleum process waters, Vlaopolous et al. Anesth Analg 1998;87:921, 3. The advantage of using this method compared to a more comprehensive LCA method is that its much simpler to carry out and to gather the required information because the data regarding the most common materials and processes has been collected in advance.
Life Cycle Assessment (LCA) - Complete Beginner's Guide - Ecochain Anesth Analg 2004;99:6267, 17. In the late 1990s, disposable LMAs became available. climate change, summer smog, resource depletion, acidification, human health effects, etc. Highlights Iatrogenic transmission of the CreutzfeldtJakob disease agent has been reported in >250 patients worldwide, and 6 of these were linked to the use of contaminated equipment, all of which were neurosurgical related. 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. 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. 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. 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 study found that: Die Basics 101: Intro to Stamping. The Fabricators, 18 July 2018, www.thefabricator.com/thefabricator/article/stamping/die-basics-101-intro-to-stamping. But what really goes into making one of these seemingly mundane disposable razors and what happens to it after its tossed in the trash? Teoh W, Lim Y. 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. A Life Cycle Assessment of Disposable Razors.
Redesigning the razor - Life Cycle Assessment - Great Recovery For a number of perioperative textiles, surgical instruments, and anesthetic devices, a life cycle assessment (LCA) has been done and has shown reusables to be environmentally favorable to disposables [ 16, 17, 18, 19, 20, 21, 22, 23 ]. Reusable LMA cleaning was observed to proceed as follows. LMA North America. endstream

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. Properly following the instructions it should (hopefully) leave you with three pieces, the handle, the metal blade, the plastic that was covering the blade.
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 Life Cycle Impact Assessment (LCIA) is where the impacts on the environment are calculated. hbbd``b`z$k@D Questions and Answers: CreutzfeldtJakob Disease Infection-Control Practices. 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. 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. By raising awareness and creating locations where one can drop off used razors for recycling, perhaps a change can come. 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 2016, Bic reduced packaging for their Soleil Razor by 40%.
Life Cycle Assessment (LCA) | Sustainable Agriculture Research The tungsten carbide is then ground into an extremely fine powder in a wet mill process, where metal binders and other metals such as cobalt may be added to increase the metals strength and durability and to help hold the powder together when it is shaped. Life Cycle Impact Assessment is the estimation of indicators of the environmental pressures in terms of e.g. There are three main components in a disposable razor. "Tungsten Processing." 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. There is also an additional resin called fluorine resin that is applied to the blades, which allows them to freely glide on the skin. DEHP is a plasticizer routinely added to impart flexibility to PVC-based products, such as IV bags, tubing, and endotracheal tubes. American Medical Association (AMA). After the reusable LMA was washed and dried, it was then placed into a heat seal pouch, made of polypropylene film and paper. However, the viability of the disposable razor is always thrown into question because of the sheer amount of resources that it expends. Anaesth Intensive Care 2004;32:5304, 4.
