This is the fourth installment in a series of blogs in which weexplore how to design a product for circularity. They have teamed up with Gillette to raise awareness about the massive waste of disposable razors by allowing users to mail their old razors in to be recycled. 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. 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). Define the Life-cycle This is an example of a simple product life-cycle diagram. 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. The Bic USAs company website provides information about the making of the razors in the factories, regarding their inspection and factory standards, yet there is no mention for the environmental impact of the disposal. 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. 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. How One Facility Completely Eliminated the Use of TCE Schick Razor Blade Manufacturing in Knoxville, Tennessee. 2017. The metal that can be used in the cartridge is also cut out during this stage. How Is Tungsten Carbide Formed? Chronicle, 20 Aug. 2015, chronicle.kennametal.com/how-is-tungsten-carbide-formed/. Staff, Creative Mechanisms. Disposable and reusable nappies in the UK: life cycle assessment The following document provides an introductory overview of Life Cycle Assessment (LCA) and describes the general uses and major components of LCA. 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. 2. 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. To make the handle and cartridges, these various plastics are heated together and melted together along with optional colorants and various filler materials. An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). 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%. An updated lifecycle assessment for disposable and reusable nappies Report that looks at the effect of disposable and reusable nappies on global warming and other environmental impacts. This assessment is exceptionally useful as it shows the designer what areas are the most impactful during the products life cycle. The reusable LMA was found to have a more favorable environmental profile than the disposable LMA as used at Yale New Haven Hospital. Highly effective in driving partnerships, public policies and projects that accelerate the shift towards a sustainable built environment. The life of a typical razor blade is not an easy one. The number of times an LMA is reused is a particularly uncertain assumption, because there have been reports of premature disposal.16 Use in excess of the manufacturer recommended 40 times has also been reported,17 and 100 to 200 uses appears to be possible with proper handling and preuse checks.1821 Here, 10, 20, 30, 60, 80, and 100 cycles are considered as alternative assumptions. 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. Marinella Levi. They are resins that maintain a high dimensional stability, which helps create fast and cheap plastic razor handles (Safety Razor). Life cycle environmental impacts of disposable medical masks The number of BIC razors that are used by consumers is astounding. Overview. Scope of the life cycle assessment for disposable and reusable laryngeal mask airways (LMAs). 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/. BIC is voicing their concern about the environmental impact that their large production goals can have. Wages are then spent on food, entertainment, transport, and other economic activities that themselves have environmental impacts. What Is Polystyrene? Being that it is such a common and quickly replaced product, this is is a major issue in terms of waste. With the recommended use of three to ten uses for disposable razors, they quickly end up in the landfill to decompose. BIC put out a report detailing how they deal with the waste from their factories. Disposable razors are a product that can be found in almost any average bathroom. 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. BIC may be doing as much as possible to lessen the impact of the production of disposable razors, but due to the massive production it will because unsustainable, because of the energy input, material consumptions, and unrecyclable nature of disposable razors. Most tungsten, about 85%, is extracted from various ores in China (Siddle, How Is Tungsten Carbide Formed?). Interpretation of results The last step in the process is to interpret the results and compare them against each other. Conducting a Life Cycle Assessment (LCA): from Theory to Practical Wolters Kluwer Health Reusable LMAs were collected in a dirty device bin on the anesthesia cart and then reprocessed by the anesthesia technicians. 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). DEHP leaches out upon exposure to heat and lipids, as would be the case in contact with mucous membranes. Once in the landfill, it usually takes around 20-30 years to breakdown. These steps are not necessarily conducted in succession, but iteratively. Using BEES to select cost-effective green products. BIC says its product beats out other models by 59 percent. By far, the biggest impact during the manufacturing of the razors was the 17 spot welds done in each cartridge. There are three main materials used in the plastic handle and the cartridge of the disposable razor. Disposable Blood Warmer Market 2023-2030 Future Forecasts The effect of alternate transport modes was quite small for the reusable LMA but quite significant for the disposable LMAs, leading to a large increase in GHG emissions in particular from air freight. 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. 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. A Life Cycle Assessment (LCA) is a methodology to assess the environmental impacts of a product or service throughout its life - from raw material extraction, manufacture and use, to end-of-life disposal, recycling or reuse. The remaining percentage is split up between energy consumption in their three facilities in: Clichy (France), Shelton (U.S.), and Cajamar (Brazil) (For You For Everyone: Registration Document, Bic). Weissman, Alexander, et al. 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. Ann Fr Anesth Reanim 2006;25:8114, 7. Anesth Analg 1998;87:921, 3. Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2010. Land transport like trains and trucks use diesel as fuel and that produced 138,700 BTU (Energy Consumption by Mode of Transportation.). Life Cycle Assessment: Biopharma SUTs - BioProcess The indirect emissions were mostly from the electricity use in the factories. your express consent. Gillette's slogan 'Gillette - the best a man can get' is famous the world over. Environment Agency (Life Cycle Assessment of Disposable and Reusable Nappies in the U.K.) investigated the impact of three diapering systems: cloth diapers with home wash, cloth diapers with commercial laundry, and disposable diapers. There are 3 key tasks in this step. 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. It all starts with the melting and combining of the desired metal. The product fails to include proper instructions for its waste management, causing it to be disposed of, as the name suggests. To begin the process of creating the metal, the tungsten is purified and ground into a fine powder. There is also an additional resin called fluorine resin that is applied to the blades, which allows them to freely glide on the skin. Overall BIC is an industry leader when it comes to reducing the environmental impact that their disposable products make. Kelly, John. 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. Enter the email address you signed up with and we'll email you a reset link. Its aim is a comprehensive analysis of the environmental impact of products and services. A life cycle assessment or analysis according to ISO 14040/14044 is an instrument of environmental and sustainability management. Complete with an ergonomic shaped non-slip rubber handle for great control and maneuverability and easy rinse blades for 100% better rinsing (vs . Properties: Tungsten Carbide-An Overview. AZoM.com, 25 Nov. 2019, www.azom.com/properties.aspx?ArticleID=1203. You may be trying to access this site from a secured browser on the server. Safety Razor. How Products Are Made, www.madehow.com/Volume-5/Safety-Razor.html. Subramaniar Trading Company. 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 biggest impact during the cartridge-based razor life-cycle is manufacturing the cartridge as this is the part which is hardest to make. Eshwar Shop. What is Life Cycle Assessment (LCA)? - Sphera endstream endobj 752 0 obj <>stream The next step in the process is the assembly of all the parts. Production of razor blades across the industry is fairly standard. 11 / Piece. BIC reported that every year around 2.6 billion of their razors are chosen by consumers every year (Shaver's). 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. Bics direct emissions were from: a combustion of fossil fuels, primarily natural gas and fuel oil, mainly used to heat buildings. 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). EPA. From the *Department of Civil and Environmental Engineering, College of Engineering, Northeastern University, Boston, MA; School of Forestry and Environmental Studies, Yale University, New Haven, CT; Department of Anesthesiology, Yale School of Medicine/YaleNew Haven Hospital, New Haven, CT. Funding: Department of Anesthesiology, Yale School of Medicine. a 4.1% (Bic). 4. The autoclave was typically run with 5 LMAs, although loading varied significantly. Life of a Razor Blade - GreatRazors.com In order to carry out the Eco-Indicator analysis method, the methodology described below has to be followed: Composition Assumptions for Disposable and Reusable Largyngeal Mask Airways (LMAs). BIC is a French manufacturing company that produces a variety of disposable consumer products like pens, lighters and disposable razors. The EPA has now stopped tracking the: impact of disposable razors on the environment and has no update on the figure (Olsen). This break-even point will change depending on the category of environmental impact being considered. On the basis of observation at Yale New Haven Hospital, it takes approximately 10 minutes to conduct all cleaning processes for 1 LMA, which is equivalent to roughly $3 in wages. Reusable LMAs in general appear to be made largely of silicone, lacking these same concerns for PVC/DEHP. From mining and extracting the natural tungsten metal, to making the metal alloy and manufacturing just the blade, waste is released. 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. Phenylene oxide, or PPO, is another common plastic material used in disposable razors. 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. The fewer LMAs placed in the autoclave, the larger the impacts on GHG emissions and global warming on each individual unit. Disposable razors are a product that can be found in almost any average bathroom. Then we collected and structured the data in phase 2. Staff, RT. 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?).
