Life cycle assessment Essays

Executive Summary Life cycle assessment is a quantitative tool used to understand the environmental impact of a product or service throughout its lifecycle. In this report, we have analysed 6 cases wherein LCA is used as a tool to strategically decide the future course of the product. Through Levi Strauss and Co. we have tried to understand new initiatives in its processes as a result of the LCA done on their Jeans manufacturing. In the Biodiesel industry, we have tried to compare the two most widely

2.2 What is Life Cycle Assessment (LCA)? Life Cycle Assessment (LCA) is a strategic framework and an effective methodology used to evaluate the environment impacts related to all the phases of a product’s life, that is, from the stage of raw material extraction , processing of materials, manufacturing, distribution, usage, repairing and maintaining the product, to its disposal. In this study, the Life Cycle Assessment (LCA) will be used for the pineapple (N36) production in Alor Bukit, Pontian

has been the cause of quite a few environmental impacts. According to the UNEP, 2014 report, lighting contributed to around 15% of global energy consumption, in the year 2010. Life cycle assessment of a product or service is the study of the environmental effects associated with the

is a comparative life cycle assessment?? A comparative L.C.A is used to compare the environmental impact of two or more products used in the same situation. LCA comes into play when your mission is to choose a product with the lowest possible environmental impact for marketing “green” construction or wanting to understand the environmental impact of that product for use. An example of this this would be in selling passive homes or NZEB (nearly zero energy buildings) This assessment will focus on steel

A life cycle assessment is an analysis of a product for it’s environmental impact. The “life cycle” of a product is every phase a product goes through, from the time it is taken out of the Earth to the time it is returned to the Earth. The assessment generally consists of four stages: defining the scope, an inventory analysis, an impact assessment and the interpretation of the results of the other stages. Life Cycle Assessments are becoming more common because of the growing concern for environmentally

Macro Environment Analysis Pest Analysis is used to analysis external macro environment that offers opportunities or threats to a company (Kolter and Armstrong, 2008). The PEST analysis is all generally considered to be an uncontrollable environment which out of the company control. PEST standing for Political, Economic, Social, and Technological. Political Analysis The growth-orientated policies of the US government help companies foster the business growth. In this context, US policies offer

2.2.2 Learning Styles Various methods to learning are related with the phases of the learning cycle. (Kolb,1984) observed the four stages of learning style which are concrete experience (CE), reflective observation (RO), abstract conceptualisation (AC), and active experimentation (AE). The model gave the basis of Kolb Learning Style Inventory which measures a learner’s favourite for certain phases of learning. Due these, it is possible to identify four learning styles, Converger (AC/AE), Diverger

practical resolution of educational problems in action research is aimed at improvement of specific localized (not generalizable) teaching-learning practices in the school covered by the research. It applies scientific method loosely in solving real-life school problems to locally improve teaching-learning quality in the particular school under

INTRODUCTION For an educator to be successful at teaching their students, the teacher must be able to asses the individual students knowledge of a subject (Guskey, 2003, p6). The clinical interview is a useful tool for assessing a student’s individual knowledge, along with other aspects of the education process. An instructor who is conducting clinical interviews are will be able to recognize the students thought process and learning behaviors when it comes to solving a problem or explaining a process

There are different strategies that can be used by the teachers for effective class management among which the most significant is clearly setting out the format of lessons. This is done with the help of setting objectives and aims, giving regular positive feedback, reviewing the learning outcomes and giving an in depth summary and final exercise to the students. While on the other hand, the teacher can also make use of rubrics for understanding the abilities of students. The teachers can also make

3. Sound design I chose this criteron because classroom assessment practices are more effective when careful attention is given to the structure and format of the assessment and because a variety of classroom assessment designs will provide a much better picture of students’ learning. ---For example: When presenting classroom assessments in an oral form (e.g., class questioning), the teacher considers: complexity of word choice, volume level of

Are standardized test truly a fair assessment of student’s abilities or not? What are standardized tests? Standardized tests are a test given to assess a student or a group of students using a test with the same questions and answers to determine students educational stand points. Standardized test are not a fair assessment for measuring student ability because they will not help students in the future, they can cause students to lose opportunities, and studies say standardized tests do not show

Grading papers felt like a huge responsibility. I was faced with the question of “who am I to give these kids these grades?” Then I realized that I was the teacher and these kids were depending on these grades to tell them what kind of progress they had made and what they needed to work on. I graded the first four and then asked my self what it was that I was doing to determine the grades I was administering. I decided to take the “Six Trait Writing Scale” and give a score on each, then add them

In summary, the nursing practice is ridden with numerous shortcomings that make it hard for patients to be satisfied with the provided health care services. This paper has provided an evidence-based model in health care provision. The need to improve patient satisfaction in the nursing practice has necessitated the implementation of relevant policies that have yielded positive results. With the nurses embracing concepts, such as teamwork, altruism, leadership, empathy, and communication, patients

Introduction Self-reflection involves processes that occur after learning efforts and influence a learner's reaction to that experience (Dunlosky, 2009). Through the self-reflection, people can analyze their own cognitive processes, their own perception, actions, and behavior gain a better understanding of themselves and of their role addressing in the workplace (Leonard, 2002). This activity is part of our future strategies for dealing with different situations where we need to direct our action

Reflective Journal Throughout the book, it emphases the importance of “faith” of social workers. Only if social workers identify their most valuable faith can they have motivation to continue on their journey of serving individual and society. Persisting in the faith is not an easy task as frustration may happen constantly. Social workers may have struggles from their lost time. However, the most important thing is to reflect what can be learnt during perplexity. A brand-new perspective of social

The Woodcock Johnson – Fourth Edition (WJ-IV) was administered in order to obtain an estimate of Isaac’s current level of cognitive functioning. Intelligence tests are intended to assess the student’s ability in acquired skills and specific knowledge, problem-solving capabilities, and memory. The scores obtained on the WJ IV can provide an estimate of the student’s performance in school. Nevertheless, these tests do not measure Isaacs’s interest in creativity, curiosity, perseverance, and motivation

RELIABILITY AND VALIDITY RELIABILITY Reliability is the consistency or repeatability of a measure For example, if I use the measurement twice (e.g. take a test twice) would my scores be the same? Reliability focuses on the consistency of the measurement. If a measurement is reliable you should get the same results if you repeat it. With any measurement the score you get is the observed score. This score is a combination of the true score and error score. Researchers would of course like to eliminate
