Table 2 shows the results of alternate assumption on the overall results. Reusable LMAs were collected in a dirty device bin on the anesthesia cart and then reprocessed by the anesthesia technicians. You Asked, We Answered. Chronicle, 12 June 2015, chronicle.kennametal.com/what-is-tungsten-carbide-you-asked-we-answered/. Data Uncertainty. The data collected through LCA helps organizations make conscious decisions that affect the environment. Wages are then spent on food, entertainment, transport, and other economic activities that themselves have environmental impacts. It can be used to study the environmental impact of either a product or the function the product is designed to perform. Brimacombe J, Keller C, Morris R, Mecklem D. A comparison of the disposable versus the reusable laryngeal mask airway in paralyzed adult patients. Finally, the razors are packaged in cardboard and plastic, and shipped out to stores and markets globally for customers to purchase and use. Life cycle assessment of a disposable and a reusable surgery instrument set for spinal fusion surgeries Leiden A, Cerdas F, Noriega D, Beyerlein J, Herrmann C. Life cycle assessment of a disposable and reusable surgery instrument set for spinal fusion surgeries. Ison E, Miller A. Differences in environmental impacts between devices may present a compelling consideration in their selection. This project is a collaboration between the Great Recovery Programme and Fab Lab London. To go from raw materials to final product involves many steps and heavy energy input. Composition Assumptions for Disposable and Reusable Largyngeal Mask Airways (LMAs). What Is Tungsten Carbide or Hard Metal? AZoM.com, 2 Aug. 2009, https://www.azom.com/article.aspx?ArticleID=4827. Now that we understand the key challenges with the razors, and where the biggest impacts are occurring, we can begin to make informed decisions in the redesign. 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. How Is Tungsten Carbide Formed? Chronicle, 20 Aug. 2015, chronicle.kennametal.com/how-is-tungsten-carbide-formed/. Sinha R, Sunder R. Retiring reusable laryngeal mask airways after 40: an anaesthetist's dilemma. 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. Chicago: American Medical Association, 2006, 27. 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. Overall BIC is an industry leader when it comes to reducing the environmental impact that their disposable products make. 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. Life Cycle Assessment (LCA) measures the impact of products on the environment. To compile a detailed life cycle inventory of the environmental burdens Materials were matched with appropriate life cycle inventory records from the ecoinvent database.11 Injection molding was assumed for the hard plastic pieces (polycarbonate and ABS plastic) and thermoforming for the softer plastics (silicone, polypropylene, and PVC). DEHP is a plasticizer routinely added to impart flexibility to PVC-based products, such as IV bags, tubing, and endotracheal tubes. 8 John Adam Street Comparison of disposable and reusable laryngeal mask airways in spontaneously ventilating adult patients. Manufacturer specifications indicate 20 kWh of electricity use for a 5-minute cycle at 135C. Anesth Analg 2012;114:105566, 8. HUO0NpnaJd@"&u[kj-+8=WU\*w)OMYb_ry> 1F3 nyNnb 0 It has a low density and is quite flexible and heat resistant, therefore making it an easily moulded and extruded material. 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). qILL@#nO @8 3 in Table 1). After the products are packaged, there has to be a way for them to get to the end consumer. Policy H-135.945: Encouraging Alternatives to PVC/DEHP Products in Health. a Centers for Disease Control. Wat LI, Brimacombe JR, Gee S. Laryngeal mask airway longevity and pilot-balloon failure. When the devices entered use at Yale New Haven Hospital, both the disposable and the reusable LMAs were removed from their original packaging, which was discarded. 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. However, it is fairly easy to find what the disposable razors components are made of, due to its simplicity. Teoh W, Lim Y. Life Cycle Assessment - definition & methodology. 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. Zhang TW, Dornfeld DA. Convenience is a potential advantage for disposable LMAs, and facilities that use reusable LMAs must ensure that a variety of sizes are always available when needed. Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. In this paper, many details about the life cycle stages were not included. The largest source of GHG emissions for the disposable LMAs (23%) is the production and polymerization of PVC, the main material constituent. 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. Atlanta, 2012. Polyphenylene Oxides.Polyphenylene Oxides - an Overview | ScienceDirect Topics, 2013, www.sciencedirect.com/topics/chemical-engineering/polyphenylene-oxides. Rogers, Tony. 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. Goal, scope and background The industrial packages sector has great importance for the transport sector in Europe. However, of the 2 billion razors disposed of annually, about 32% end up in the ocean (Kaplan). 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. This is done on an assembly line by the robotic arm the inserts the razor blade into the small crevices in the plastic body. Ecoinvent 2.2. Anaesth Intensive Care 2004;32:5304, 4. EPA. Figueredo E. Changes in the intracuff pressure of the laryngeal masks airway caused by repeated use. PurposeIn this study, a life cycle assessment of a bioplastic based diaper was performed. Olsen, Alexandra. `""(w When you take your blades in to the scrap metal center, choose the steel recycling bin. Assessing all steps in that life cycle provides insight into individual stresses and burden shifts from one step to another and enables understanding of both the cumulative environmental impacts and related trade-offs in each area, throughout the lifespan of both a facility and its manufactured products. 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. There is also an additional resin called fluorine resin that is applied to the blades, which allows them to freely glide on the skin. Silver Spring, MD: U.S. Food and Drug Administration, 2002, 26. 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. LCA's are completed particularly in relation to how to develop a sustainable world where less waste and more reuse is implemented. The LMA was then dried with a cotton towel. Each year in Italy, millions of tons of fruits and vegetables are harvested, packed and transported to national and foreign retail outlets. Everything You Need To Know About Polystyrene (PS). Everything You Need To Know About Polystyrene (PS), 5 Nov. 2015, https://www.creativemechanisms.com/blog/polystyrene-ps-plastic. CASE STUDY ANALYSIS - CLEAN EDGE, NON DISPOSABLE RAZOR Q1. climate change, summer smog, resource depletion, acidification, human health effects, etc. 1. The more capital-intensive option of increasing the energy efficiency of the autoclave machines by 10% decreases GHG emissions by 8%. 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. 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. Bic Disposable Razor (1975). Plastics News Europe, 19 Nov. 2009, www.plasticsnewseurope.com/article/20091119/PNE/311199986/bic-disposable-razor-1975. BIC has done their best to deal with waste in an environmentally conscious manner. There are only two components for the BIC disposable razors which are the plastic body and razor blade. Phenylene oxide, or PPO, is another common plastic material used in disposable razors. These steps are not necessarily conducted in succession, but iteratively. Wolters Kluwer Health 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 What Is Polystyrene? 0 8tZ The metal used for the razor blades is called Tungsten Carbide which is used in wear applications, such as shaving (Safety Razor). This assessment is exceptionally useful as it shows the designer what areas are the most impactful during the products life cycle. 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. For You for Everyone Registration Document. In landfilling or incinerating this part, the large amount of energy and material value used in creating it is lost. 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. Life cycle assessment (LCA) is a framework for assessing the environmental impacts of product systems and decisions. 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. Amersfoort, The Netherlands: Product Ecology (PR) Consultants, 2011, 11. 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. Polystyrene is not biodegradable and takes hundreds of years to break down. Marine cargo ships use a fuel called heavy fuel oil which produces around 145,000 BTU per gallon (Energy Consumption by Mode of Transportation.). Swiss Center for Life Cycle Inventories. The Eco-Indicator for EPDM rubber includes the manufacturing of the rubber as well as the molding process. For both environmental and cost considerations, management and operating procedures should be put in place to ensure that reusable LMAs are not discarded prematurely. 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. My next blog post will show some design recommendations using sketches and 3D-printed prototypes. In this post I havent shown the whole process, but there are downloadable links to my full Eco-Indicator results, and to the template form if youd like to carry out an assessment yourself. 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? 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. The unit cost of disposable LMAs is 20% higher at approximately $9.60 per unit. 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. Paper diapers for infants, which are highly convenient as they do not require laundering like cloth diapers, are essential for daily life in Japan. Here, Great Recovery Intern Sebastian de Cabo Portugal discusses Life Cycle Assessments. The original LMA was a reusable device (Intavent International SA, Henley-on-Thames, UK). Until now, we defined what we want to measure and collect in phase 1. Anesth Analg 1993;77:1079, 21. BIC said that around 98 percent of its intercompany product transfer was done by transportation methods that were not related to air-freight (For You For Everyone Registration Document). Data is temporarily unavailable. After the products make their way to consumers and serve their purpose, the waste must be dealt with. BIC is a French manufacturing company that produces a variety of disposable consumer products like pens, lighters and disposable razors. 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.

Tungsten Carbide. Encyclopdia Britannica, Encyclopdia Britannica, Inc., 17 Dec. 2018, www.britannica.com/science/tungsten-carbide. Marinella Levi. By raising awareness and creating locations where one can drop off used razors for recycling, perhaps a change can come. 3. Europe, Plastic News. 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. A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. BIC has reported their total energy usage and carbon footprint in their factories around the world, this was all however for the year 2016. Anaesth Intensive Care 2010;38:538, 9. Your message has been successfully sent to your colleague. 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%). Please enable scripts and reload this page. Product Ecology (PR) Consultants. 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. 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). 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. Eshwar Shop. The specific type or blend of plastic for BIC razors is used is called polystyrene (Europe).
