Considering human health concerns, the majority (60%) of impacts for the disposable LMA is due to the production of polymers, PVC in particular, with emissions from incineration contributing another 15%. Powers, Matt, and Amanda M. Can You Recycle Disposable Razors? Earth911.Com, 30 July 2019, earth911.com/living-well-being/health/can-you-recycle-disposable-razors/. 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. BIC put out a report detailing how they deal with the waste from their factories. 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). What is Life Cycle Assessment (LCA)? | iPoint-systems 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. The life cycle assessment results shown here allow clinicians and health care administrators to understand the balance between direct benefits of a given LMA choice to local patient care and the environmental and human health impacts of that choice that occur far from the operating room. The processes that contribute to these emissions differ markedly between the 2 LMA devices. The next step in the process is the assembly of all the parts. The disposable LMA consisted largely of polyvinyl chloride (PVC) plastic, and the reusable LMA consisted primarily of silicone. Choosing a less-green disposable will magnify your razor's manufacturing impact, but it won't change the overall picture very much. 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. The International Journal of Life Cycle Assessment. After the parts are manufactured it is time for the final product assembly. 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. My next blog post will show some design recommendations using sketches and 3D-printed prototypes. BIC reported that every year around 2.6 billion of their razors are chosen by consumers every year (Shaver's). Properly Recycle Your Disposable Razors | Leafygreen.info For example, the designer might think that the manufacturing stage would be the most impactful, when in reality for some products its the raw material extraction or its use phase. An LCA is a life cycle assessment which is completed through research, testing and understanding of the environmental impacts a particular item creates through it's resources use/ production/distribution/disposal. Life Cycle Analysis (LCA) - A Complete Guide to LCAs 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. 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). 3.Quantify the materials and processes 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. 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.

Comparison of reusable and disposable medical textiles. Several waste management scenarios were also considered, including 100% landfilling and 100% incineration, because practices are highly location dependent. Anesthesia & Analgesia114(5):1067-1072, May 2012. Steel Life Cycle.SSAB, www.ssab.com/company/sustainability/sustainable-offering/steel-life-cycle?di=discover21C927E58ECC41198B78D915F7E3E2AF. Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. 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. Marine cargo ships use a fuel called heavy fuel oil which produces around 145,000 BTU per gallon (Energy Consumption by Mode of Transportation.). Polystyrene. Wikipedia, Wikimedia Foundation, 2 Dec. 2019, en.wikipedia.org/wiki/Polystyrene. Life cycle assessment comparison among different reuse intensities for Julabo Gmbh, et al. Anesth Analg 1993;77:1079, 21. Reusable LMA cleaning was observed to proceed as follows. Goodman EJ, Haas AJ. The hardest part of this whole process is the data gathering. Poly(Phenylene Oxide). The Polymer Science Learning Center, www.pslc.ws/macrog/ppo.htm. The EPA has said in their 2014 report: Currently, little information is available about the fate and transport of tungsten in the environment and its effects on human health. Comparative environmental and human health (HH) impacts for disposable and reusable laryngeal mask airways (LMA), Building for Environmental and Economic Sustainability (BEES) impact assessment method. endstream endobj startxref 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. 11 / Piece. All that is needed is the insertion of the razor blade into the plastic body. Staff, RT. Siddle, Dave. 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. There are three main components in a disposable 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. Life Cycle Assessment Study single use vs. multiple use Marvel Product Razor Lady Body Shaver Disposable Razore. 0 8tZ Disposable razors are designed for consumers that prefer minimum spending . Address e-mail to [emailprotected]. . Complete with an ergonomic shaped non-slip rubber handle for great control and maneuverability and easy rinse blades for 100% better rinsing (vs . 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?). A life cycle assessment or analysis according to ISO 14040/14044 is an instrument of environmental and sustainability management. Finally, the need for manual labor in the cleaning process of reusable LMAs contributed to the costs of these LMAs. 761 0 obj <>/Filter/FlateDecode/ID[]/Index[748 22]/Info 747 0 R/Length 72/Prev 421064/Root 749 0 R/Size 770/Type/XRef/W[1 2 1]>>stream Data is temporarily unavailable. 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). (i)What changes occurring in non-disposable Razor category? The study found that: 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). At every point during planning, production, and even marketing, the quantity of consumption should be analyzed to adjust business models accordingly. Bic did have an increase in non-hazardous waste due to: expansion work or renovation of buildings or development of new products and manufacturing equipment (For You For Everyone: Registration Document, Bic) For carbon footprint assessments for large companies, they are assessed on direct (scope 1) emissions and indirect (scope 2) emissions of greenhouse gases. Life Cycle Assessment (LCA) measures the impact of products on the environment. hb```X ea i:=3*?a_.k7#uq-u[JRP erle@@)`EkP;~ cdC58xiv06@Jup E 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 has reported their total energy usage and carbon footprint in their factories around the world, this was all however for the year 2016. Metal materials are sent for smelting and conversion to new alloys (Terracycle). Being that it is such a common and quickly replaced product, this is is a major issue in terms of waste. LCA for product sustainability. Disposable Blood Warmer Market 2023-2030 Future Forecasts Their disposable nature causes them to be put into landfills faster than it takes them to be made, packaged, and shipped. Any extra plastic will be discarded, remelted, and reused (Safety Razor, madehow.com). 3 in Table 1). Can J Anaesth 2001;48:40912, 22. One of their most popular products is the disposable razor, which they started to manufacture in 1975. 5.Interpret and analyse the results. 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). An exact number for the energy use for BIC was not obtained. LCA's are completed particularly in relation to how to develop a sustainable world where less waste and more reuse is implemented. Upgrading to a new, energy-efficient autoclave machine leads to a nearly equal reduction in life cycle GHG emissions and may be considered particularly in instances in which older equipment is being used. 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. However, the viability of the disposable razor is always thrown into question because of the sheer amount of resources that it expends. Safety Assessment of Di(2-ethylhexyl)phthalate (DEHP) Released from PVC Medical Devices. Life Cycle Assessment (LCA) is a technique for assessing the potential environmental aspects and potential aspects associated with a product (or service), by: compiling an inventory of relevant inputs and outputs, evaluating the potential environmental impacts associated with those inputs and outputs, (PDF) Sources, Fate and Effects of Microplastics in the Marine Once all the components of the razor have been made, the components go to various stations where different tasks will be performed. 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 majority of life cycle human health impacts of disposable LMAs are caused by PVC use in packaging and the device itself. 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. "Tungsten Processing." The Nation's Freight: U.S. Bureau of Transportation Statistics. Research and Innovative Technology Administration. The cheap price of the razor does not reflect the high cost of its waste and impact on the environment. I could however not find any details about the energy consumption of the machines used in the assembly process. In this process, the metal is heated to temperatures of 1,967-2,048F (1,075-1,120C), then quenched in water to a temperature between -76- -112 F (-60- -80 C) to harden it. By raising awareness and creating locations where one can drop off used razors for recycling, perhaps a change can come. A 20-mL disposable syringe was used during device placement to inflate the cuffs of both types of LMAs to ensure proper fit, and a procedure was then performed. 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. Eckelman, Matthew PhD*; Mosher, Margo; Gonzalez, Andres; Sherman, Jodi MD. By far, the biggest impact during the manufacturing of the razors was the 17 spot welds done in each cartridge. 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. 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. 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. Such an analysis is commonly performed using life cycle assessment. 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. 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 decision-making process of device selection. Some error has occurred while processing your request. James Drinkwater - Head of Built Environment - LinkedIn associated with the environmental interventions attributable to the life-cycle of a product. Die Basics 101: Intro to Stamping.

Address correspondence to Jodi Sherman, MD, Yale University, School of Medicine, Department of Anesthesiology, 333 Cedar Street, TMP3, New Haven, CT 06520. These benefits must be weighed against concerns regarding transmission of infection. Life Cycle Assessment (LCA) and Solid Waste Management Consultants To start the process of making the blades, tungsten carbide is melted at high temperatures. Ann Fr Anesth Reanim 2006;25:8114, 7. WC2N 6EZ, Redesigning the razor Life Cycle Assessment. BIC says its product beats out other models by 59 percent. Each manufacturing plant or node in the supply chain is referred to as agate-to-gate (GTG) life cycle inventory. 13, 14 There are few published life cycle assessment studies of medical items (ref. 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. The major problem with recycling this plastic however, is that during the heating process, the plastic degrades in quality making it less valuable (What Is Tungsten Carbide or Hard Metal?, AZoM.com). What Is Tungsten Carbide?" All of these software packages and models are in widespread use by life cycle assessment practitioners in the US and internationally. The Great Recovery was a project by the RSA working with Innovate UK which ran between 2012 and 2016. :396?Qkt)e. 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. Europe, Plastic News. This is the fourth installment in a series of blogs in which weexplore how to design a product for circularity. 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). Gillette Sensor3 Sensitive Men's Disposable Razors : Target 8 John Adam Street The newest effort to recycle disposable razors is being done in France by BIC, but the company has said that they do not plan on unveiling a recycling program anywhere else yet (Powers). The second component of the razor is the plastic body which is made of a fairly inexpensive plastic called polystyrene. 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). Williams S, Henderson K. A survey into the number of times laryngeal masks are used. Sustainable Development at BIC . 6 Jan. 2011. Overview. EPA. The laryngeal mask airway (LMA) was introduced into clinical use in the late 1980s and approved by the Food and Drug Administration (FDA) for use in the US in 1991. Table 2 shows the results of alternate assumption on the overall results. 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.). In this paper, life cycle assessment (LCA) has been used as a tool to quantify the environmental impacts of disposable medical face masks.
