The Editors of Encyclopaedia Britannica. This practice meets American Society of Anesthesiologists' recommendations for infection control for equipment requiring high-level disinfection.14. associated with the environmental interventions attributable to the life-cycle of a product. 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). 2. This means, of the 2 billion razors disposed of annually within the United States, each razor will be on the planet longer than the people who used them. 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. Each time the steam autoclave machine conducts a sterilizing cycle, a large amount of energy is used to heat the steam. The Great Recovery was a project by the RSA working with Innovate UK which ran between 2012 and 2016. Pollution of the oceans from plastics has become an increasingly large issue that researchers are still assessing. The stability of the plastic components, while necessary for shelf stability and use, takes longer than one persons life-span to decompose. Overcash M. Comparison of reusable and disposable medical textiles. Features Downloads. These benefits must be weighed against concerns regarding transmission of infection. Poly(Phenylene Oxide). The Polymer Science Learning Center, www.pslc.ws/macrog/ppo.htm. In this case its the life-cycle of the cartridge-based razor. Research about tungsten is ongoing and includes health effects and risks, degradation processes and an inventory of its use in the defense industry as a substitute for lead-based munitions (EPA). 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). 85 percent of the energy came from electricity, 14 percent came from gas, and the rest came from fuel oil (For You For Everyone Registration Document). U.S. Environmental Protection Agency. 3.Quantify the materials and processes After that the blades go through a blade edging process, which consists of the blade strips first being coarsely ground by whetstone, second being ground at an angle with a finer whetstone, and then having the tip of the blades ground (Manufacturing Processes). Choosing a less-green disposable will magnify your razor's manufacturing impact, but it won't change the overall picture very much. When designing a product for circularity it is often difficult to know where to begin. 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. Contact Supplier. Cad M, Webb T, Bjorksten A. Once Terracycle has collected the waste, it is: broken down and separated by material. The blades do eventually dissipate within the landfill, yet, it is not cost-free, as the tungsten waste can be ultimately harmful to the environment. 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. The metal must be mined and extracted from the mountain causing an emission of fossil fuels and greenhouse gases (Wang). 1. 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. Since BICs products do not go to a single location it is impossible to give an exact number for BICs energy usage in transportation. 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. However, BIC did report some of its transportation statistics. This obviously makes the results less accurate, but it can still be used as a general indicator of impact. Its aim is a comprehensive analysis of the environmental impact of products and services. endstream endobj startxref A Life Cycle Assessment of Disposable Razors. A Comparative Life Cycle Assessment of Disposable and Reusable Packaging for the Distribution of Italian Fruit and Vegetables. There are many detailed stages but the main ones are: extracting and. 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. The backbone of LCA is the life cycle inventory (LCI), an analysis of material and energy ows resulting from all phases of the product life cycle. Disposable razors are a product that can be found in almost any average bathroom. Wages are then spent on food, entertainment, transport, and other economic activities that themselves have environmental impacts. Ecoinvent 2.2. It is resistant to fats and almost all organic solvents which helps it hold up in the damp and warm conditions of a bathroom and shower (Polypropylene. Wikipedia.org). Anesth Analg 2004;99:6267, 17. After the products make their way to consumers and serve their purpose, the waste must be dealt with. 1. 1. All of these equipment-related cases occurred before the routine implementation of sterilization procedures currently used in health care facilities. Reusable LMAs in general appear to be made largely of silicone, lacking these same concerns for PVC/DEHP. Anyone can send in razors of any kind, and the plastic and cardboard packaging as well. The unit cost of disposable LMAs is 20% higher at approximately $9.60 per unit. The LMAs were first rinsed in tap water, scrubbed externally with a Hibiclens sponge and internally with a small scrub brush, and rinsed again. 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. Reprints will not be available from the authors. 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 EPA has now stopped tracking the: impact of disposable razors on the environment and has no update on the figure (Olsen). 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. Current LMA procurement decisions are typically based on perceived costs. 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. Gillette Mach3 Men's Disposable Razor for Sensitive Skin - Best Cartridge Razor for Sensitive Skin. To make the handle and cartridges, these various plastics are heated together and melted together along with optional colorants and various filler materials. Gillette Plastic Disposable Shaving Kit supermax, for Hotel. 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. After the products are packaged, there has to be a way for them to get to the end consumer. 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. Comparison of disposable and reusable laryngeal mask airways in spontaneously ventilating adult patients. 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. The largest source of GHG emissions for the disposable LMAs (23%) is the production and polymerization of PVC, the main material constituent. Saudi J Anaesth 2008;2:58. : Uses, Benefits, and Safety Facts, ChemicalSafetyFacts.org,). 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. Comparison of the single use and reusable intubating laryngeal mask airway. A comparative cradle to grave life cycle assessment (LCA) was conducted to determine and analyze the environmental impacts of using disposable acrylic speculums versus using reusable stainless-steel speculums in a women's university health clinic where around 5,000 pelvic exams are conducted on a yearly basis. The study found that: Chicago: American Medical Association, 2006, 27. Ison E, Miller A. 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. 3 in Table 1). In the late 1990s, disposable LMAs became available. 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. There is uncertainty in several model assumptions. Our LCA team retains its reputation as the most experienced life cycle staff in North America. The plastic, however stable for the user, remains stable long after it is thrown away as well. 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 Part of this responsible shipping mentality forces them to change their packaging to be able to ship more at a time. To compile a detailed life cycle inventory of the environmental burdens Disposable razors are a product that can be found in almost any average bathroom. There are land, air, and water-based transportation methods. 748 0 obj <> endobj 3.7.Product Life Cycle Analysis . %PDF-1.5 % Zhang TW, Dornfeld DA. Overall, reusable LMAs were found to have fewer negative environmental effects in nearly all categories, typically contributing <50% of the impacts of disposable LMAs. 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 tracking can come from sales, and in 2018 more than $1.2 billion in disposable razors were sold in the U.S., with varying prices but many disposables costing less than $1 each (Olsen). Address correspondence to Jodi Sherman, MD, Yale University, School of Medicine, Department of Anesthesiology, 333 Cedar Street, TMP3, New Haven, CT 06520. It is used to assist companies, consumers, and policy-makers in greening their practices and decisions. There could be hundreds of different sources for their materials. There are 3 key tasks in this step. Anesth Analg 2012;114:105566, 8. 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. LCA for product sustainability. From:. 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 The aim of this paper is to analyse substitutes to disposable plastic tableware using the Life Cycle Assessment methodology. 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. 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. McGain F, McAlister S, McGavin A, Story D. The financial and environmental costs of reusable and single-use plastic anaesthetic drug trays. Contribution: This author helped design the study and prepare the manuscript. 1.Establish the purpose of the Eco-Indicator calculations 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. The metal that can be used in the cartridge is also cut out during this stage. Main methodological choices . Gillette Razor Local Recycling Solutions.TerraCycle, www.terracycle.com/en-US/brigades/gillette-local-recycling. Its an extremely strong and durable metal compound, making it perfect for the use of razor blades (Siddle, How Is Tungsten Carbide Formed?; Tungsten Carbide. Wikipedia.org). Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2010. 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. It can be used to study the environmental impact of either a product or the function the product is designed to perform. 3. A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. 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. For example, LCA results can tell us if one product is environmentally preferable to another . Weissman, Alexander, et al. 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. 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. There are only two components for the BIC disposable razors which are the plastic body and razor blade. BIC reported that every year around 2.6 billion of their razors are chosen by consumers every year (Shaver's). Another material used is polystyrene. What makes for an easy, simple, and affordable mass produced and used product costs more in its long afterlife in the landfill, out of sight of the buyers awareness.
