Swiss Center for Life Cycle Inventories. Next, the razors will be tested for flaws, strength, and razor hardness and sharpness (Safety Razor, madehow.com). Available at: http://www.cdc.gov/ncidod/dvrd/cjd/qa_cjd_infection_control.htm. 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 The metal liquid then goes through a strengthening process called annealing. The alternatives are objects made of bio compostable plastic,. 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. 2011, Packaging Technology and Science. Lippiatt BC, Boyles AS. 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. Environmental LCA - Life Cycle Initiative This is where most of the complexity of an LCA is involved. Interpretation of results The last step in the process is to interpret the results and compare them against each other. Life Cycle Assessment (LCA) | Sustainable Agriculture Research These results will then be used to inform the design process and improve the redesigned razor. To aid in solving this issue, I believe consumers should stray away from wasteful disposable razors and be encouraged to go with more sustainable and longer lasting options such as classic safety razors. 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). Comparative life cycle assessment of disposable and reusable - PubMed 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. Life Cycle Assessment (LCA) explained - PR Sustainability Safety Razor. How Products Are Made www.madehow.com/Volume-5/Safety-Razor.html. 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. 2. 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).
