BIC put out a report detailing how they deal with the waste from their factories. The more capital-intensive option of increasing the energy efficiency of the autoclave machines by 10% decreases GHG emissions by 8%. Sinha R, Sunder R. Retiring reusable laryngeal mask airways after 40: an anaesthetist's dilemma. There is also an additional resin called fluorine resin that is applied to the blades, which allows them to freely glide on the skin. Washington, DC: U.S. Environmental Protection Agency, 2011, 16. Once in the landfill, it usually takes around 20-30 years to breakdown. Gillette Plastic Disposable Shaving Kit supermax, for Hotel. 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. Poly(Phenylene Oxide). The Polymer Science Learning Center, www.pslc.ws/macrog/ppo.htm. 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). 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. Polystyrene. Wikipedia, Wikimedia Foundation, 2 Dec. 2019, en.wikipedia.org/wiki/Polystyrene. This break-even point will change depending on the category of environmental impact being considered. After the end of their recommended lifetime, reusable LMAs were also placed in municipal solid waste containers. Manufacturing Processes (RAZOR): KAI FACTORY: KAI Group. KAI FACTORY | KAI Group, www.kai-group.com/global/en/kai-factory/process/razor/. The blades and lubricating strip were too light to be measured with our equipment so their weights were rounded to 1g. Anaesth Intensive Care 2010;38:538, 9. GaBi is a LCA software that allows its users to connect environmental impacts to a product across its lifespan. 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. 13, 14 There are few published life cycle assessment studies of medical items (ref. All of these equipment-related cases occurred before the routine implementation of sterilization procedures currently used in health care facilities. The metal used for the razor blades is called Tungsten Carbide which is used in wear applications, such as shaving (Safety Razor). BIC Group, 2016, For You For Everyone Registration Document. In this paper, life cycle assessment (LCA) has been used as a tool to quantify the environmental impacts of disposable medical face masks. 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.). Kaplan, Desire. 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 biggest impact during the cartridge-based razor life-cycle is manufacturing the cartridge as this is the part which is hardest to make. U.S. Environmental Protection Agency. In this life cycle breakdown, I will be discussing what materials go into the making of disposable razors and what processes the materials go through in the operation of making a disposable razor. Data is temporarily unavailable. 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. The Life Cycle Impact Assessment (LCIA) is where the impacts on the environment are calculated. The original LMA was a reusable device (Intavent International SA, Henley-on-Thames, UK). 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. A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. The most important sources of impacts for the disposable LMA were the production of polymers, packaging, and waste management, whereas for the reusable LMA, washing and sterilization dominated for most impact categories. Depending upon on how the razor is packaged, the finished cartridge may or may not be assembled onto the handle of the razor, as some companies choose to package the handle detached the cartridge(s). Tungsten carbide is a carbide compound, made up of equal parts of tungsten and carbon. disposable paper diaper; material recycling; closed-loop recycling; life cycle assessment (LCA) 1. Subramaniar Trading Company. 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/. Address e-mail to [emailprotected]. The life cycle of plastics Life cycle assessment (LCA) considers the environmental aspects associated with a product over its lifespan. 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. This is where most of the complexity of an LCA is involved. Until now, we defined what we want to measure and collect in phase 1. 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. 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. There are only two components for the BIC disposable razors which are the plastic body and razor blade. For me, I had a few extra bits of plastic that I snapped off because they . 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. Their disposable nature causes them to be put into landfills faster than it takes them to be made, packaged, and shipped. Anesth Analg 2004;99:6267, 17. 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. Overcash M. Comparison of reusable and disposable medical textiles. These steps are not necessarily conducted in succession, but iteratively. Scope of the life cycle assessment for disposable and reusable laryngeal mask airways (LMAs). Buy Now.

Two Life Cycle Impact Assessment (LCIA) methodologies were employed using SimaPro software 51,52 to calculate the environmental impacts of manufacturing both the plastic and compostable coffee . LCA is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service. Saudi J Anaesth 2008;2:58. Production of razor blades across the industry is fairly standard. In their study of Life cycle assessment of wastewater treatment technologies treating petroleum process waters, Vlaopolous et al. Contact Supplier. The majority (77%) of life cycle CO2e emissions for the reusable LMA is from natural gas production and combustion to produce steam for the autoclave machine. Life Cycle Assessment - definition & methodology. LCA's are completed particularly in relation to how to develop a sustainable world where less waste and more reuse is implemented. The Eco-Indicator method is a tool developed to help designers conduct a simplified LCA study. Overall BIC is an industry leader when it comes to reducing the environmental impact that their disposable products make. Anesth Analg 1993;77:1079, 21. What Is Tungsten Carbide or Hard Metal? AZoM.com, 2 Aug. 2009, https://www.azom.com/article.aspx?ArticleID=4827. Due to the nature of the disposable razor, they are usually just thrown in the trash and sent off to a landfill. A new incentive must come for companies to be more sustainable with resources and create products that can still be cheap for the buyer, while also not taking a high cost on the environment. Whereas transportation has a relatively significant GHG impact for the disposable LMAs, by comparison the transportation of reusable LMAs has little impact on GHG emissions, because 40 disposable LMAs must be shipped to provide an equivalent function to 1 reusable LMA. Biron, Michel. Pollution of the oceans from plastics has become an increasingly large issue that researchers are still assessing. Cad M, Webb T, Bjorksten A. xTkJ((5:Ome\%{yIlka;K=1 Life Cycle Assessment (LCA) is a modeling tool for quantifying the environmental impacts of products and processes. Table 2 shows the results of alternate assumption on the overall results. 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). Comparison of disposable and reusable laryngeal mask airways in spontaneously ventilating adult patients. 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. The next step is to temper the steel at a temperature of 482-752F (250- 400C) and pressed into thin sheets (Safety Razor, madehow.com). 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. Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2010. 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. Anaesth Intensive Care 2004;32:5304, 4. 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. My next blog post will show some design recommendations using sketches and 3D-printed prototypes. 3.Quantify the materials and processes Several waste management scenarios were also considered, including 100% landfilling and 100% incineration, because practices are highly location dependent. This document is an update and merger of two previous EPA documents on LCA ("Life Cycle Assessment: Inventory Guidelines and Principles," EPA/600/R-92/245, and "LCA101" from the LCAccess, website . We are proud that it is among the leading professional LCA software . 4. What Is Polystyrene? f'C58NQ}i:]1
$Nh@b8H|iWILGgj{J27]Xp0N@h+ !` >q A SYSTEMATIC METHODOLOGY FOR ACCURATE DESIGN-STAGE ESTIMATION OF ENERGY CONSUMPTION FOR INJECTION MOLDED PARTS. Because the human health impacts of the disposable LMAs are dominated by plastics, increasing the amount of PVC by 10% leads to a significant (>5%) increase in cancer and noncancer effects. HUO0NpnaJd@"&u[kj-+8=WU\*w)OMYb_ry> 1F3
nyNnb 0 Holes are then punched into the metal and the tapelike sheets of razors are then put in a roll (Manufacturing Processes). 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. 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. Impact Assessment. 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. : Uses, Benefits, and Safety Facts.ChemicalSafetyFacts.org, 17 June 2019, www.chemicalsafetyfacts.org/polystyrene/. Data Uncertainty. 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). Resources, Conservation & Recycling 156 (2020) 104704. Environmental Life-Cycle Assessment of Disposable Bioreactors - BioProcess InternationalBioProcess International Upstream Processing Bioprocessing begins upstream, most often with culturing of animal or microbial cells in a range of vessel types (such as bags or stirred tanks) using different controlled feeding, aerating, and process strategies. At 20 reuse cycles,16 the results indicate an increase in emissions of nearly 20%. The company reported that with their hazardous waste in 2016 11 percent was recycled, 49 percent incinerated with energy recovery, 8 percent sent to land disposal, and 32 percent was sent off to be treated in another way (For You for Everyone Registration Document). 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). This manuscript was handled by: Steven L. Shafer, MD. The US Environmental Protection Agency's Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) life cycle impact assessment method was used to model environmental impacts of greenhouse gases and other pollutant emissions. your express consent. 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. Overview. 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. 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 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. Gillette Mach3 Men's Disposable Razor for Sensitive Skin - Best Cartridge Razor for Sensitive Skin. These benefits must be weighed against concerns regarding transmission of infection. The study found that: 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. Cited Here. The product fails to include proper instructions for its waste management, causing it to be disposed of, as the name suggests. Sets Strategy to End 'Staggering' Garbage Crisis.The New York Times, The New York Times, 23 Sept. 1988, www.nytimes.com/1988/09/23/us/epa-sets-strategy-to-end-staggering-garbage-crisis.html. The largest source of GHG emissions for the disposable LMAs (23%) is the production and polymerization of PVC, the main material constituent.
