Define the Life-cycle This is an example of a simple product life-cycle diagram. Each razor can last up to 12 gentle shaves. What Is Polystyrene? 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. 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. 11,772. 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. 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. All that is needed is the insertion of the razor blade into the plastic body. 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). Amersfoort, The Netherlands: Product Ecology (PR) Consultants, 2011, 11. Atlanta, 2012. Enter the email address you signed up with and we'll email you a reset link. A Comparative Life Cycle Assessment of Disposable and Reusable Packaging for the Distribution of Italian Fruit and Vegetables. The hardest part of this whole process is the data gathering. 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). We are proud that it is among the leading professional LCA software . What is Life Cycle Assessment (LCA)? - Sphera Chu L, Mathur P, Trudell J, Brock-Utne J. To begin the process of creating the razor blades, tungsten carbide, which is the metal that the blades and other optional components are made of, must first be manufactured. hb```X ea i:=3*?a_.k7#uq-u[JRP erle@@)`EkP;~ cdC58xiv06@Jup E Anesth Analg 2012;114:105566, 8.

International Sympsium on Sustainable Systems and Technology. It has been assumed that the packaging contains cardboard, even though it has been made from other natural fibres like bamboo, as there is no info on those materials in the Eco-Indicator tables. The blades do eventually dissipate within the landfill, yet, it is not cost-free, as the tungsten waste can be ultimately harmful to the environment. 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). (ii)Access paramount's competitive position? Poly(Phenylene Oxide). The Polymer Science Learning Center, www.pslc.ws/macrog/ppo.htm. Manufacturing Processes (RAZOR): KAI FACTORY: KAI Group. KAI FACTORY | KAI Group, www.kai-group.com/global/en/kai-factory/process/razor/. 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. How One Company Keeps Used Razors Out Of Oceans.Green Matters, Green Matters, 25 Sept. 2017, www.greenmatters.com/news/2017/09/25/Z1oInGt/razors-ocean. 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. Amazon.com: Bulk Disposable Razors The Great Recovery was a project by the RSA working with Innovate UK which ran between 2012 and 2016. Disposable and reusable nappies in the UK: life cycle assessment Safety Razor. How Products Are Made www.madehow.com/Volume-5/Safety-Razor.html. Life cycle assessment software I used GaBi 6 software, produced by PE International. The specific type or blend of plastic for BIC razors is used is called polystyrene (Europe). An estimated 1 L of tap water was used to wash and rinse 1 LMA (or 40 L over a lifetime of 40 uses). However, of the 2 billion razors disposed of annually, about 32% end up in the ocean (Kaplan). After the plastic body is manufactured it goes through inspections similar to ones the blades go through. This is where most of the complexity of an LCA is involved. LCA is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service. The LMA was then dried with a cotton towel. The use of disposable razors is unsustainable with our growing population and increased demand. Life cycle assessment of stainless-steel reusable speculums versus In this section we also need to state the assumptions made during the process: These included alternative routes and modes of transport from San Diego to New Haven, changes in autoclave loading practices and efficiency, and varied amounts of PVC in the disposable LMA. Reusable LMAs were collected in a dirty device bin on the anesthesia cart and then reprocessed by the anesthesia technicians. A 2005 analysis published by U.K. Contrary to common expectation, hair is actually pretty hard. #4. This is where the razors are portioned into their desired packaging amounts, that will be sent off to consumers. This liquid material is then injected into moulds, or extruded through moulds, where it will cool and take the form of the desired cartridge and handle shape. The high waste from manufacturing and shipping such a small, and cheap product is one that is negatively impacting the planet. The LMAs were first rinsed in tap water, scrubbed externally with a Hibiclens sponge and internally with a small scrub brush, and rinsed again. endstream endobj 752 0 obj <>stream Features Downloads. Disposable and reusable LMAs typically differ in material composition, packaging, reuse, and cost. LCA can be used to compare alternative products, processes or services; compare alternative life cycles for a certain product . 0 8tZ Select patients who are highly infective warrant the choice of disposable devices; however, data do not support selecting disposables for all patients to avoid any possible risk of infection. Silver Spring, MD: U.S. Food and Drug Administration, 2002, 26. The plastic, however stable for the user, remains stable long after it is thrown away as well. Life Cycle Assessment: Biopharma SUTs - BioProcess %%EOF Anaesthesia 2000;55:7001, 18. In phase 3, we evaluate how significant the impacts are. Any extra plastic will be discarded, remelted, and reused (Safety Razor, madehow.com). 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. . PurposeIn this study, a life cycle assessment of a bioplastic based diaper was performed. EPA. However, given the environmental toll to such a fast accumulating, and non-biodegradable product, waste management must be more considered by both the manufacturers and the buyers. B|$5 During shaving, the sharp edges of the blade will chip off at a slow but steady rate, dulling the blade after repeated shavings. 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 largest source of GHG emissions for the disposable LMAs (23%) is the production and polymerization of PVC, the main material constituent. This is the fourth installment in a series of blogs in which weexplore how to design a product for circularity. The following document provides an introductory overview of Life Cycle Assessment (LCA) and describes the general uses and major components of LCA. Life Cycle Assessment (LCA) explained - PR Sustainability 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. Waste is not only a problem when a product is disposed of, but also when it is initially manufactured. 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. You Asked, We Answered. Chronicle, 12 June 2015, chronicle.kennametal.com/what-is-tungsten-carbide-you-asked-we-answered/. Each year in Italy, millions of tons of fruits and vegetables are harvested, packed and transported to national and foreign retail outlets. 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. The alternatives are objects made of bio compostable plastic,. 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. To start the process of making the blades, tungsten carbide is melted at high temperatures. Resources, Conservation & Recycling 156 (2020) 104704. LCA is a standardized, science-based tool for quantifying the impact in order to assess lifetime environmental impact. 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. Wolters Kluwer Health Facilities that select reusable devices should implement inventory and operating procedures that ensure that devices are reused to the greatest possible extent. 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, Disposable razors are created for a short user time, and an easy answer to the growing populations fast paced lifestyles and needs for shaving: they are primarily designed to be simple, economical, and disposable (Safety Razor). Life cycle assessment comparison among different reuse intensities for By raising awareness and creating locations where one can drop off used razors for recycling, perhaps a change can come. Policy H-135.945: Encouraging Alternatives to PVC/DEHP Products in Health. There are so many variables that you have to take into account when calculating how much of an impact a product is having on the environment and our resources. The original LMA was a reusable device (Intavent International SA, Henley-on-Thames, UK). What does a business area's assessment of agreements, income, and value implicate? The alloy is strong enough to resist moisture for a short time in the buyers shower, yet, in the landfill, it does eventually rust and decompose. At every point during planning, production, and even marketing, the quantity of consumption should be analyzed to adjust business models accordingly. Life Cycle Assessment - IPP - Environment - European Commission Life Cycle Assessment (LCA): A Guide to Best Practice - ResearchGate 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. 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. RSA This project is a collaboration between the Great Recovery Programme and Fab Lab London. use/disposable and multiple-use/washable surgical gowns. Life cycle assessment (LCA) is a framework for assessing the environmental impacts of product systems and decisions. Properly following the instructions it should (hopefully) leave you with three pieces, the handle, the metal blade, the plastic that was covering the blade. Applying this method of assessment is complex and difficult and translating the theory into a . Rogers, Tony. 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). Address correspondence to Jodi Sherman, MD, Yale University, School of Medicine, Department of Anesthesiology, 333 Cedar Street, TMP3, New Haven, CT 06520. Certain practices would further reduce the environmental impacts of reusable LMAs, such as increasing the number of devices autoclaved in a single cycle to 10 (25% GHG emissions) and improving the energy efficiency of the autoclaving machines by 10% (8% GHG emissions). Contribution: This author helped conduct the study and analyze the data. 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. 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.. Iatrogenic transmission of the CreutzfeldtJakob disease agent has been reported in >250 patients worldwide, and 6 of these were linked to the use of contaminated equipment, all of which were neurosurgical related. Washington, DC: U.S. Bureau of Transportation, 2002, 14. BIC has done their best to deal with waste in an environmentally conscious manner. It can also help them to compare the newly redesigned product to the original, acting as a benchmark to ensure the design changes are actually positive for the environment. The polypropylene is sorted during recycling using a float test that separates it from other materials based on its ability to float due to its weight, then it is often melted down and reused in other product manufacturing. Then we collected and structured the data in phase 2. Safety Razor.How Products Are Made, www.madehow.com/Volume-5/Safety-Razor.html. Sinha R, Sunder R. Retiring reusable laryngeal mask airways after 40: an anaesthetist's dilemma. There could be hundreds of different sources for their materials. Sustainable Development Report. Saudi J Anaesth 2008;2:58. Manufacturing Processes (RAZOR): KAI FACTORY: KAI Group.KAI FACTORY | KAI Group, www.kai-group.com/global/en/kai-factory/process/razor/. Sensitivity and simple life cycle cost analyses were conducted to aid in interpretation of the results. 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. Life Cycle Assessment - definition & methodology. PDF An updated lifecycle assessment study for disposable and reusable nappies 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. Yet, as they are designed to be thrown away after use, a question is raised of their fast accumulating waste and its impact on the environment. 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. In the case of the disposable razor however, it is fairly simple due to its nature. The alloy must allow for easy manufacturing due to the high demand of disposable razors and enough strength to last through transportation and shelf holding. The blade is made from a tungsten steel, and carbon alloy. Washington, DC: U.S. Environmental Protection Agency, 2011, 16. Energy Consumption by Mode of Transportation. Energy Consumption by Mode of Transportation | Bureau of Transportation Statistics, Bureau of Transportation Statistics, www.bts.gov/content/energy-consumption-mode-transportation. On the basis of such criteria, single-use disposable medical devices are increasingly supplanting reusable devices in the United States (US) and elsewhere.1 Although purchase and maintenance costs for disposable devices are perceived to be less than for reusables, this fails to account for indirect costs to society from the environmental impacts attributable to the entire life cycle of a device.
