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. 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. The human-health-related impact categories are pertinent to those developing standards for the delivery of health care. Disposable razors are a product that can be found in almost any average bathroom. Park Ridge, IL: American Society of Anesthesiologists, 1999, 15. The results also suggest effective procurement strategies for reducing the impacts of disposable LMAs where they are selected. After the products make their way to consumers and serve their purpose, the waste must be dealt with. Reusable LMA cleaning was observed to proceed as follows. LMAs may be composed of 40% DEHP by weight. 2.Define the life-cycle This assessment is exceptionally useful as it shows the designer what areas are the most impactful during the products life cycle. Sensitivity and simple life cycle cost analyses were conducted to aid in interpretation of the results. Our team of experts has many years of experience in the ecological evaluation of products and services. 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. However, of the 2 billion razors disposed of annually, about 32% end up in the ocean (Kaplan). disposable paper diaper; material recycling; closed-loop recycling; life cycle assessment (LCA) 1. Int J Life Cycle Assess 2001;6:7680, 13. Safety Assessment of Di(2-ethylhexyl)phthalate (DEHP) Released from PVC Medical Devices. #4. The total amount of indirect emissions was 89,762 tonnes of carbon dioxide (For You For Everyone Registration Document). These results suggest that the reusable LMA Classic has fewer life cycle impacts in comparison with the disposable LMA Unique at Yale New Haven Hospital, across several categories of concern. Data is temporarily unavailable. Packaging is an . To begin the process of creating the metal, the tungsten is purified and ground into a fine powder. Swiss Center for Life Cycle Inventories. The body of both razors had similar impact as their weights were also quite similar. 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. They are resins that maintain a high dimensional stability, which helps create fast and cheap plastic razor handles (Safety Razor). The blades are then carefully sharpened to create the razor blades. 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. Contact Supplier. 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. Zhang TW, Dornfeld DA. 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. : Uses, Benefits, and Safety Facts, ChemicalSafetyFacts.org,). Teoh W, Lim Y. Europe, Plastic News. 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. In the late 1990s, disposable LMAs became available. Anesth Analg 1993;77:1079, 21. Pollution of the oceans from plastics has become an increasingly large issue that researchers are still assessing. Direct emissions refer to any emissions that resulted from the burning of fossil fuels and Indirect emissions refer to any emissions that resulted from the generation of electricity. 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. Choosing models that use alternate materials is recommended, particularly because the American Medical Association is urging hospitals and health systems to reduce their use of PVC products, especially those containing DEHP.26 The shipment of LMAs by air also greatly increased overall impacts, pointing to a strategy of bulk ordering from local distributors well in advance of use, and avoiding overnight shipment whenever possible. Polystyrene is not biodegradable and takes hundreds of years to break down. The newest effort to recycle disposable razors is being done in France by BIC, but the company has said that they do not plan on unveiling a recycling program anywhere else yet (Powers). 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 study found that: The Bic Razor, Still the Sharpest of the Bunch. Plastics Le Mag, 31 Jan. 2017, plastics-themag.com/The-Bic-razor-still-the-sharpest-of-the-bunch. 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. 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. After the plastic body is manufactured it goes through inspections similar to ones the blades go through. Alternate assumptions were used to test model sensitivity and to create bounds to aid interpretation of the results (Table 2). 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. Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2010. 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. Yet, tungsten has been found to deposit particles into the soil that causes some contamination, making it a recent concern to the United States Environmental Protection Agency. Recommendations for Infection Control for the Practice of Anesthesiology. The International Journal of Life Cycle Assessment. Enter the email address you signed up with and we'll email you a reset link. Sensitivity and simple life cycle cost analyses were conducted to aid in interpretation of the results. Therefore, to help designers get started and make informed decisions, a Life cycle Analysis (LCA) can be carried out using the information gathered during the research stage. At the end of applying the additives, the blades are once again heated, to cement the coating onto the blade. may email you for journal alerts and information, but is committed a Centers for Disease Control. However, it is fairly easy to find what the disposable razors components are made of, due to its simplicity. Life Cycle Approach to Plastic Pollution - Life Cycle Initiative Our news to your inbox Click to subscribe to LC Net info@lifecycleinitiative.org About Us Our Activities & Tools Reports & Training News & Events Get Involved Life Cycle Approach to Plastic Pollution Activities Life Cycle Assessment in High-Impact sectors The Eco-Indicator method is a tool developed to help designers conduct a simplified LCA study. Nash, Nathaniel C. HOW BIC LOST THE EDGE TO GILLETTE. The New York Times, The New York Times, 11 Apr. 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. 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). 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). Lv, Andrea Lind, and Tigist Fetene. 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. 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. It is also often not accepted in curbside recycling, and even when it is, it is not separated and recycled when it reaches the dumping station, making it an unsustainable and wasteful material (Polystyrene. Wikipedia.org). This is where most of the complexity of an LCA is involved. There are some solutions and new recycling ideas, yet, the reduction of waste for disposable razors is still far off. All of which provides an easy user experience, but, takes a toll on the planet. . 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). 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 reusable LMA was found to have a more favorable environmental profile than the disposable LMA as used at Yale New Haven Hospital. 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. Williams S, Henderson K. A survey into the number of times laryngeal masks are used. 4. The tungsten carbide is then ground into an extremely fine powder in a wet mill process, where metal binders and other metals such as cobalt may be added to increase the metals strength and durability and to help hold the powder together when it is shaped. 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. Soulias M, Martin L, Garnier N, Juniot A, Aho L, Freysz M. Disposable vs reusable laryngeal mask airway: a cost-minimization analysis. The following document provides an introductory overview of Life Cycle Assessment (LCA) and describes the general uses and major components of LCA. Safety Razor. How Products Are Made www.madehow.com/Volume-5/Safety-Razor.html. Now that we understand the key challenges with the razors, and where the biggest impacts are occurring, we can begin to make informed decisions in the redesign. Each manufacturing plant or node in the supply chain is referred to as agate-to-gate (GTG) life cycle inventory. 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. 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.
