McGain F, McAlister S, McGavin A, Story D. The financial and environmental costs of reusable and single-use plastic anaesthetic drug trays. The tables didnt contain values for welding steel, so it has been assumed that the value is close to welding aluminium which is in the table. Some error has occurred while processing your request. #4. 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. In addition, although this life cycle assessment study did not analyze health impacts during use of an LMA, intraoperative exposure to diethylhexyl phthalate (DEHP) is of some concern. 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. 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. 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. Brimacombe J, Keller C, Morris R, Mecklem D. A comparison of the disposable versus the reusable laryngeal mask airway in paralyzed adult patients. This LCA is specific for surgical gowns used in the Twin Cities of Minneapolis and St Paul, Minnesota. 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. 4. 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. The company urges users to mail packages over 15 lbs., in order to reduce the waste of mail as well, yet is not necessary. Pollution of the oceans from plastics has become an increasingly large issue that researchers are still assessing. Using Life Cycle Assessments to Understand Cloth vs. Disposables - BAHP A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. 2011, Packaging Technology and Science. Thomas, G.P. What Is Polystyrene? Reusable LMAs in general appear to be made largely of silicone, lacking these same concerns for PVC/DEHP. The body of both razors had similar impact as their weights were also quite similar. There are land, air, and water-based transportation methods. The next step the blade goes through is called polishing in which is done using strops made out of cowhide to get the desired blade edge shape, the blade is then cut into the sizes of the individual blades, which are then sent off to be inspected. The buyer online is not exposed to the long lasting waste of the razors after they are thrown out. Anesth Analg 1998;87:921, 3. Life cycle assessment - Environmental Assessment and Optimization Group Manufacturers can do this solely by machine or by human eye/hand plus machine for extra quality assurance. What IS Life Cycle Assessment? By not using air travel and transport, BIC greatly reduces their energy usage and carbon footprint at the same time. A major flaw in the disposable razors design is in fact its inability to be sustainably and properly disposed, despite what its name suggests. An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). I could however not find any details about the energy consumption of the machines used in the assembly process. After the parts are manufactured it is time for the final product assembly. Figure: Life Cycle Assessment steps: goal and scope definition, life cycle inventory, life cycle impact assessment and interpretation (Sala et al., 2016) In the goal and scope phase, the aims of the study are defined, namely the intended application, the reasons for carrying out the study and the intended audience. Life Cycle Assessment (LCA) - Complete Beginner's Guide - Ecochain They have also reduced shipping time, by only sending the blades from Greece to Mexico to optimize the tools and products available in each location, instead of having all the materials shipped to each factory. 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 Gillette Mach3 Disposable Razors for Men, 6 Count, Designed for Sensitive Skin. The main causes of the reusable LMA's environmental impacts are the steam used in the autoclave sterilizing machine and, to a lesser extent, the wastewater generated from washing the LMAs. Product Ecology (PR) Consultants. The total amount of indirect emissions was 89,762 tonnes of carbon dioxide (For You For Everyone Registration Document). There much environmentally friendly options when it comes to shavings, such as the traditional safety razor and straight razors, which can have a much longer life than disposable razors. 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. Next, the razors will be tested for flaws, strength, and razor hardness and sharpness (Safety Razor, madehow.com). Reducing Trichloroethylene (TCE) Waste in the Fabricated Metals Sector.EPA, Environmental Protection Agency, 9 Aug. 2016, www.epa.gov/toxics-release-inventory-tri-program/reducing-trichloroethylene-tce-waste-fabricated-metals-sector. 2 offers from $9.92. Previous studies have examined the relative environmental profiles of reusables and disposables with regard to medical textiles7 and anesthetic drug trays.8 The present study uses life cycle assessment to evaluate the life cycle impacts of disposable and reusable LMAs across several categories of environmental and human health impacts. Anaesthesia 2000;55:7001, 18. 3.7.Product Life Cycle Analysis . DEHP leaches out upon exposure to heat and lipids, as would be the case in contact with mucous membranes. Paper diapers for infants, which are highly convenient as they do not require laundering like cloth diapers, are essential for daily life in Japan. Gathering all the data for the LCA is the most difficult part of the task, and normally assumptions have to be made where its impossible to gather all the knowledge required, thus not all the relevant impacts are considered. 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. Main methodological choices . 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 Poly(Phenylene Oxide). The Polymer Science Learning Center, www.pslc.ws/macrog/ppo.htm. These impacts are quantified here in terms of energy use, water use, and greenhouse gas (GHG) emissions using general factors for US labor.22. Life cycle assessment - Universitetet i Agder Life cycle assessment software I used GaBi 6 software, produced by PE International. This means that it takes around 1 BTU to heat a 0.035-ounce razor blade to the desired temperature (Julabo et.al). During the research, I could not find how much energy BIC injection molding machines use, but I did find the energy usage of a common injection molding machine called the Babyplast. Gillette Mach3 Men's Disposable Razor for Sensitive Skin - Best Cartridge Razor for Sensitive Skin. With the results we supply the basis for strategic decisions for sustainable action. On the other hand, extending the number of uses to 80 (doubling the lifetime) reduces GHG emissions by 9%. 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. 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. "Tungsten Processing." 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). They have estimated that they expend around 11.77 gigajoules of energy per ton of their products that they produce (For You For Everyone Registration Document) The BIC report also categorized the energy where they obtained the energy. What does a business area's assessment of agreements, income, and value implicate? 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. 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. Tungsten has a high melting point and is used mainly for strong tools unless used for smaller applications when combined with a carbon alloy: Its alloys are employed in rocket-engine nozzles and other aerospace applications (Safety Razors). The environmental effects of labor are often omitted from life cycle assessment studies, but are included here as part of the sensitivity analysis. All of these software packages and models are in widespread use by life cycle assessment practitioners in the US and internationally. There are three main materials used in the plastic handle and the cartridge of the disposable razor. These containers, mainly wooden pallets and spools, are subject to European legislat 2. There are only two components for the BIC disposable razors which are the plastic body and razor blade. Polypropylene is recyclable with the resin code of 5, which is its numbered identification code that is used to identify what resins plastic products are made of, and indicate how they are recycled. BIC has done their best to deal with waste in an environmentally conscious manner. At 20 reuse cycles,16 the results indicate an increase in emissions of nearly 20%. Disposable razors are a product that can be found in almost any average bathroom. Life cycle assessment (LCA) is a method used to estimate the total environmental impacts from producing a good or service. 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. Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. The mixed plastics used in most of the razor take hundreds of years to break down in landfill, and the blades, while the metal is recyclable if separated from the rest of the product, poses a safety hazard for both the consumer and the employees who handle recyclables. In landfilling or incinerating this part, the large amount of energy and material value used in creating it is lost. Scope of the life cycle assessment for disposable and reusable laryngeal mask airways (LMAs). Phase 3: Life Cycle Impact Assessment. The largest source of GHG emissions for the disposable LMAs (23%) is the production and polymerization of PVC, the main material constituent. The GTG LCIs are added together to give a cradle-to-gate (CTG) life cycle inventory . Facilities that select reusable devices should implement inventory and operating procedures that ensure that devices are reused to the greatest possible extent. 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. The LMA, within the heat seal pouch, was then placed in the steam autoclave sterilizing machine (Castle/Getinge MC 3522). 2.Define the life-cycle 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. 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. LCA's are completed particularly in relation to how to develop a sustainable world where less waste and more reuse is implemented. HUO0NpnaJd@"&u[kj-+8=WU\*w)OMYb_ry> 1F3 nyNnb 0 After the reusable LMA was washed and dried, it was then placed into a heat seal pouch, made of polypropylene film and paper. The purpose of this assessment is to compare two different types of razors: cartridge based vs. double edge safety razor. Since then, around 60 billion razors have been produced, distributed, and sold worldwide. Anesthesiology 2003;99:1066, 6. The metal is then heated and then cooled slowly to remove any internal stress, which makes it tougher, this process is called annealing (Safety Razor). Anesth Analg 1993;77:1079, 21. 3. Table 2 shows the results of alternate assumption on the overall results. 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). Polystyrene. Wikipedia, Wikimedia Foundation, 2 Dec. 2019, en.wikipedia.org/wiki/Polystyrene. Life Cycle Assessment (LCA) measures the impact of products on the environment. The Environmental Protection Agency classifies DEHP as a probable carcinogen, and as a possible endocrine disrupter.24 The FDA issued an advisory in 2002 recommending steps be taken to reduce the risk of exposure to DEHP in certain populations.25 There is enough evidence of reproductive and developmental toxicant effects from DEHP for the FDA to recommend alternatives for patients deemed at high risk, namely infants, toddlers, and pregnant and lactating women. According to studies done by the EPA, tungsten steel was originally tested as a stable metal in soil that does not dissolve easily in water (EPA). 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. 45. From mining and extracting the natural tungsten metal, to making the metal alloy and manufacturing just the blade, waste is released. An LCA is an accounting of the inputs and outputs for a product system, beginning with extraction of raw materials from the earth and continuing through all of the steps of transportation, manufacturing, product fabrication, product use, and end-of-life, which may include reuse, recycling . A Comparison Life Cycle Assessment between Razor Blade and Electric Shaver. Dec. 2012. Sustainable Development at BIC . 6 Jan. 2011. Each time the steam autoclave machine conducts a sterilizing cycle, a large amount of energy is used to heat the steam. At the end of applying the additives, the blades are once again heated, to cement the coating onto the blade. Tungsten is a natural metal deposit that is found in metamorphic, and granitic igneous rocks, primarily in China, Russia, South Korea, South America, and the Rocky Mountains in the United States. The scope of our analysis, as is shown in Figure 1, includes extraction of material and energy resources, manufacturing, packaging and transport from the manufacturing site to the distribution center and the hospital, reprocessing, and eventual disposal. Experience spanning from the market-leading environment and climate practice of a global top 10 law firm - to leading Europe's largest . Wang, Chun Tsin, and Alexander Sutulor. The blades are then carefully sharpened to create the razor blades. This manuscript was handled by: Steven L. Shafer, MD. Each manufacturing plant or node in the supply chain is referred to as agate-to-gate (GTG) life cycle inventory. Chu L, Mathur P, Trudell J, Brock-Utne J. By far, the biggest impact during the manufacturing of the razors was the 17 spot welds done in each cartridge. Redesigning the razor - Life Cycle Assessment - Great Recovery Tungsten carbide is a carbide compound, made up of equal parts of tungsten and carbon. B|$5 3 Ways to Recycle Safety Razor Blades - wikiHow Life 6,474. LCA is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service. The study found that: Highly effective in driving partnerships, public policies and projects that accelerate the shift towards a sustainable built environment. 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. Staff, RT. Max Soft Disposable Razor For Women - 3 Pcs In A Pack. BIC put out a report detailing how they deal with the waste from their factories. The materials used in the production of disposable razors are limited due to the products simplicity however, many of the materials are unsustainable in that they are not biodegradable or easily recyclable, and require heavy energy input to manufacture. 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). LMA Classic Product Specifications, 2011, 10. Another material used is polystyrene. hb```X ea i:=3*?a_.k7#uq-u[JRP erle@@)`EkP;~ cdC58xiv06@Jup E Life Cycle Assessment explained: an introduction to building LCA 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 results also suggest effective procurement strategies for reducing the impacts of disposable LMAs where they are selected. Uncertainties about the correctness of the model. Choosing a less-green disposable will magnify your razor's manufacturing impact, but it won't change the overall picture very much. Holes are then punched into the metal and the tapelike sheets of razors are then put in a roll (Manufacturing Processes). In conclusion, disposable razors are being used and thrown away at a rate that is unsustainable for the finite space on the planet. Life Cycle Assessment Study single use vs. multiple use The LMA was then dried with a cotton towel. 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. 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. Bics direct emissions were from: a combustion of fossil fuels, primarily natural gas and fuel oil, mainly used to heat buildings. 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. It has a low density and is quite flexible and heat resistant, therefore making it an easily moulded and extruded material. The disposable LMA consisted largely of polyvinyl chloride (PVC) plastic, and the reusable LMA consisted primarily of silicone. The Eco-Indicator for EPDM rubber includes the manufacturing of the rubber as well as the molding process. (iii)What are the strategic lifecycle challenges for paramount's current products as well as for clean edge? A Life Cycle Assessment of Disposable Razors. How Is Tungsten Carbide Formed? Chronicle, 20 Aug. 2015, chronicle.kennametal.com/how-is-tungsten-carbide-formed/. Not all form of impacts are valued the same, so the ones with the largest impact should be tackled first in order to produce the maximum overall improvement. Define the Life-cycle This is an example of a simple product life-cycle diagram. 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). Life Cycle Analysis (LCA) - A Complete Guide to LCAs 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. Individually autoclaving the reusable LMA (because of stock shortages, for example) increased life cycle GHG emissions by >400%, whereas loading with 10 LMAs per cycle decreased emissions by nearly 25%. Policy H-135.945: Encouraging Alternatives to PVC/DEHP Products in Health. Life Cycle Assessment: Disposable paper cups by Shanice Robbins Criteria for the selection and purchase of medical devices typically include safety for patients and staff, efficacy and ease of use, and purchase and handling prices. LeBlanc, Rick.

Atlanta, 2012. 11 / Piece. Part of this responsible shipping mentality forces them to change their packaging to be able to ship more at a time. Life of a Razor Blade - GreatRazors.com Teoh W, Lim Y. Being that it is such a common and quickly replaced product, this is is a major issue in terms of waste. The metal is heated to a temperature of 1967-2048 degrees Fahrenheit and tungsten carbide has a specific heat of 0.226 BTU/lb/Fahrenheit (Safety razor). Ison E, Miller A. Criteria air pollutants arise for the disposable LMA primarily from the production of ethylene (a polymer precursor) and the combustion of natural gas throughout the system, and for the reusable LMA from the combustion of fossil fuels to produce steam and electricity. associated with the environmental interventions attributable to the life-cycle of a product. Safety Razor. How Products Are Made www.madehow.com/Volume-5/Safety-Razor.html. 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.). Once Terracycle has collected the waste, it is: broken down and separated by material. 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. 13, 14 There are few published life cycle assessment studies of medical items (ref. Life Cycle Assessment (LCA) | Sustainable Agriculture Research For waste management, switching from 100% incineration to 100% landfilling typically reduced impacts across all categories by 5%10%, with the national average scenario results decreasing in between. The indirect emissions were mostly from the electricity use in the factories. Sensitivity and simple life cycle cost analyses were conducted to aid in interpretation of the results. Address e-mail to [emailprotected]. The aim of this paper is to analyse substitutes to disposable plastic tableware using the Life Cycle Assessment methodology. Lippiatt BC, Boyles AS. Disposable Razors at Best Price in India - IndiaMART This obviously makes the results less accurate, but it can still be used as a general indicator of impact. Reusable LMA cleaning was observed to proceed as follows. Nash, Nathaniel C. HOW BIC LOST THE EDGE TO GILLETTE. The New York Times, The New York Times, 11 Apr. Marvel Product Razor Lady Body Shaver Disposable Razore. 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. The metal is not yet to its final form, as it is still greatly held together by the previously added binders. SimaPro 7.3.2. Life Cycle Assessment of Disposable and Reusable Nappies in the UK Ref: ISBN 1844324273, LIT 2080 PDF, 1.83 MB, 203 pages This file may not be suitable for users of assistive technology.. Available at: http://www.cdc.gov/ncidod/dvrd/cjd/qa_cjd_infection_control.htm. My next blog post will show some design recommendations using sketches and 3D-printed prototypes. 1. The majority of life cycle human health impacts of disposable LMAs are caused by PVC use in packaging and the device itself. The number of BIC razors that are used by consumers is astounding. In BIC factories they pride themselves in producing a quality product, so the blades go through a series of highly precise visual inspections with cameras which help with rejecting blades that do not meet BIC standards (Case Studies) After that they go through visual inspection is done be BIC employees to reject any blades that the cameras were not rejected by the inspection camera system, the blades are then send off to be coated and burned.
