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. Wang, Chun Tsin, and Alexander Sutulor. I could however not find any details about the energy consumption of the machines used in the assembly process. Polystyrene is a naturally transparent thermoplastic that is available as both a typical solid plastic as well in the form of a rigid foam material (Rodgers, Everything You Need To Know About Polystyrene (PS).). 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. "Tungsten Processing." The purpose of this assessment is to compare two different types of razors: cartridge based vs. double edge safety razor. BIC has repeatedly come under fire because of the environmental impact their disposable razors have, due to the sheer amount of their disposable products are used every year. Life cycle assessment is a "cradle-to-grave" approach for determining the financial and environmental costs of a product over its entire life. We are proud that it is among the leading professional LCA software . The use of disposable razors is unsustainable with our growing population and increased demand. a Centers for Disease Control. There is no public data entailing the details of this plastics recyclability. A Life Cycle Assessment is the systematic analysis of the environmental impact of products during their entire life cycle. 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.. your express consent. Each time the steam autoclave machine conducts a sterilizing cycle, a large amount of energy is used to heat the steam. Plastics are cleaned and pelletized to be recycled into new products, such as picnic tables and park benches. 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. Redesigning the Razor Life Cycle Assessment. The Great Recovery, http://www.greatrecovery.org.uk/resources/3682/. 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). This manuscript was handled by: Steven L. Shafer, MD. The Fate of the Disposable Razor.Industrial Equipment News (IEN), 7 Aug. 2019, www.ien.com/product-development/news/21081402/the-fate-of-the-disposable-razor. Another material used is polystyrene. Ann Fr Anesth Reanim 2006;25:8114, 7. Properties: Tungsten Carbide-An Overview. AZoM.com, 25 Nov. 2019, www.azom.com/properties.aspx?ArticleID=1203. It has a low density and is quite flexible and heat resistant, therefore making it an easily moulded and extruded material. The Nation's Freight: U.S. Bureau of Transportation Statistics. Contamination problems with reuse of laryngeal mask airways and laryngoscopes. The 2 LMA options are nearly equivalent in terms of eutrophication impacts, but with different contributions. The LCA is broken into four stages: Defining the goal and scope how much of a product's lifecycle will be addressed, the reasons for carrying out the assessment, the intended audience, and the intended end-use [] 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. 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). For a number of perioperative textiles, surgical instruments, and anesthetic devices, a life cycle assessment (LCA) has been done and has shown reusables to be environmentally favorable to disposables [ 16, 17, 18, 19, 20, 21, 22, 23 ]. The specific type or blend of plastic for BIC razors is used is called polystyrene (Europe). Waste is not only a problem when a product is disposed of, but also when it is initially manufactured. :396?Qkt)e. In the case of the disposable razor however, it is fairly simple due to its nature. Staff, RT. I found information about the whole blade manufacturing process, but could not find details about energy consumption in every step of the process. 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. Rogers, Tony. disposable paper diaper; material recycling; closed-loop recycling; life cycle assessment (LCA) 1. The fewer LMAs placed in the autoclave, the larger the impacts on GHG emissions and global warming on each individual unit. Sustainable Development at BIC . 6 Jan. 2011. The majority of life cycle human health impacts of disposable LMAs are caused by PVC use in packaging and the device itself. Amersfoort, The Netherlands: Product Ecology (PR) Consultants, 2011, 11. Polystyrene is not biodegradable and takes hundreds of years to break down. 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. 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, An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). 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. This is where most of the complexity of an LCA is involved. Anesthesia & Analgesia114(5):1067-1072, May 2012. 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. Enter the email address you signed up with and we'll email you a reset link. BIC has reported their total energy usage and carbon footprint in their factories around the world, this was all however for the year 2016. LCA for product sustainability. Siddle, Dave. In order to carry out the Eco-Indicator analysis method, the methodology described below has to be followed: 1.Establish the purpose of the Eco-Indicator calculations 2.Define the life-cycle 3.Quantify the materials and processes 4.Complete the form 5.Interpret and analyse the results 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. 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. Being that it is such a common and quickly replaced product, this is is a major issue in terms of waste. 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. When you take your blades in to the scrap metal center, choose the steel recycling bin. 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. E-LCA is a time tested assessment technique that evaluates environmental performance throughout the life cycle of a product or from performing a service. The following document provides an introductory overview of Life Cycle Assessment (LCA) and describes the general uses and major components of LCA. However, it is fairly easy to find what the disposable razors components are made of, due to its simplicity. The International Journal of Life Cycle Assessment. After the reusable LMA was washed and dried, it was then placed into a heat seal pouch, made of polypropylene film and paper. The blades and lubricating strip were too light to be measured with our equipment so their weights were rounded to 1g. The differences in environmental impacts between these devices strongly favor reusable devices. These are the reasons why I will carry out an Eco-Indicator Assessment instead of a full LCA. Gillette's slogan 'Gillette - the best a man can get' is famous the world over. 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. The differences in environmental impacts between these devices may present a compelling consideration in device selection when concern for infection transmission is not a factor. Contribution: This author helped conduct the study and analyze the data. The powder is then shaped, usually by the process of die stamping. Disposable LMAs are made largely from PVC plastic, which is associated with a number of health concerns that are gaining increased attention.23 Historic efforts to minimize routine medical incineration resulted in the 1998 Memorandum of Understanding between the American Hospital Association and the US Environmental Protection Agency, largely on the basis of recognition of the potential carcinogenic effects of burning PVC plastics. However, they also affirmed that they strive to make their products with an eco-design approach by using recycled materials or bioplastics in their different products (For You for Everyone Registration Document). During production, two components have to be created which are the blade and the plastic body. Weissman, Alexander, et al. 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. 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. In phase 3, we evaluate how significant the impacts are. Recommendations for Infection Control for the Practice of Anesthesiology. After the end of their recommended lifetime, reusable LMAs were also placed in municipal solid waste containers. 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. Here, Great Recovery Intern Sebastian de Cabo Portugal discusses Life Cycle Assessments. Conversely, impacts can be reduced by autoclaving more LMAs at once or with other equipment with similar decontamination requirements. 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. LCA can be used to compare alternative products, processes or services; compare alternative life cycles for a certain product . Choosing a less-green disposable will magnify your razor's manufacturing impact, but it won't change the overall picture very much. There is always some level of uncertainty in the results and in the methodology; so users shouldnt take the numbers shown as absolute values, but more as a guide to prioritise work. Anaesth Intensive Care 2004;32:5304, 4. 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. A life-cycle inventory of cloth and disposable diapers was conducted based on diapering habits in Canada The parameters evaluated were energy consumption, water consumption, raw materials 15 Crop water use and water use efficiency on irrigated cotton farms in Australia S. Tennakoon, S. Milroy Environmental Science 2003 93 LCA is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service. 2019, science.howstuffworks.com/environmental/green-science/polystyrene-recycling.htm. BIC is a French manufacturing company that produces a variety of disposable consumer products like pens, lighters and disposable razors.
