Untitled picture.png Machine generated alternative text: Question I Not yet answered Marked out of 7.00 Flag question use the ISO 14040-2006 to match the following definitions related to the Principles of LCA: Due to the complexity ot an LCA, transparency is an impoäant guiding principle to ensure proper interpretation ot results. LCA considers the entire lite cycle ot a product, trom raw material extraction and acquisition, through energy and material production and manufacturing, to use and end of lite treatment and final disposal. Decisions within an LCA are preferably based on natural science. IF this isn't possible, then other scientific approaches (such as social or economics) should be applied. LCA addresses the environmental aspects and impacts of a product system. Economic and social aspects are, typically, outside the scope of the LCA. The individual phases of an LCA use the results ot other phases. T ne iterative approach within and beüeen phases contributes to the comprehensiveness and consistency ot the study. LCA is a relative approach that is structured around a functional unit. The functional unit (tu) defines what is being studied. All analysis are relative to the tut LCA considers all attributes or aspects ot the natural environment, human health, and resources. As such, possible trade-otts can be identified and assessed.

According to the ISO 14040-2006 document, the LCA process can assist in: (Click all that are true. Negative marks apply to selecting the incorrect answers). Select one or more: a the selection of relevant indicators ot environmental peäormance, including measurement techniques, 5. marketing (e.g. eco-laöelling, making environmental claims, environmental production declaration)? c. Identifying opportunities to improve the environmental performance ot products at various points in their lite cycle d. informing decision-makers in industry, government or non-government organizations (tor the purpose ot strategic planning, priority setting, product or process design/redesign).

(wrong answers receive negative marks) It is helpful to describe the system using a process flow diagram snowing the unit processes and their inter-relationships. Each unit process should be initially described to define: Select one or more: a where the unit process ends, in terms ottne destination, but only for final product 5. where the unit process ends, in terms ottne destination for intermediate and final products c. the nature of transformation as a result ottne unit process d. where the unit process begins, in terms of intermediate products e. where the unit process begins, in terms of raw materials

What pan ot the extraction economy do we see? Planned obsolescence is defined as: What is the challenge of incinerating our garbage? What percent ot materials are still in use 6 months atter point ot sale? product packaging change seventy manufacturing Designed tor the dump release of toxins one Untitled picture.png Machine generated alternative text: Question 6 Not yet answered Marked out of 3.00 Flag question Lite cycle thinking considers the following as pan of the product/process over ts entire lite cycle.

Throughout it, we need to consider people as pan ot the process, along with transport related to the production, sale, and use ot these products. T ne Lite Cycle starts witn raw materials extraction and production followed by packaging and distribution As consumers, we see mainly the cyclical big business profits production , and end of life/recycling use phase and a small part of distribution when we purchase goods and disposal manufacturing when we get rid of them.

In the first phase: System boundaries Goal and Scope , we define the intended use and audience of our LCA. The Scope ottne LCA includes and an idea on the level ot detail the LCA will cover. In an LCA, a provides details on what is being examined/provided and for now long. In phase 2: Lite Cycle Inventory Analysis compile and quantity functional unit inputs and outputs for the must be defined. This entire lite cycle. We may use process flow diagrams to help understand complex systems. System boundaries are needed to separate the system from the rest of the world . Flows should be followed until economic inputs and outputs are translated into also need to In phase 3: Finally, in phase 4: compile and quality Lite Cycle Impact Assessment Lite Cycle Interpretation as many processes contain multiple functions. , we understand and evaluate the magnitude and significance ot environmental interventions environmental _ We may impacts. we identity, interpret, and evaluate. This includes a written report and summary of findings. Findings are discussed as a basis tor conclusions, recommendations, and decision-making in accordance witn the goal and scope definition. certain aspect ot a allocate economic recomendations Untitled picture.png Machine generated alternative text: Question 10 Not yet answered Marked out of 1_00 Flag question Complete the following sentence.
