Life cycle assessment

Life cycle assessment is a tool that can be used to evaluate and compare the environmental effect of a product, process, or activity throughout its life cycle or lifetime, which is known as a “from cradle to grave” analysis (Poritosh Roy 2009). It can be used to assess environmental burdens, finding opportunities for process and product improvement, and selection of process technology, energy or raw material sources. LCA has been used extensively by researchers to evaluate and compare various MSW waste to energy systems (Khoo, 2009, Leme et al., 2014, Zaman, 2013, Ning et al., 2013, arena et al., 2015, Evangelisti et al., 2015). However, few researchers have used Life Cycle Assessment to investigate and compare MSW treatment with gasification technologies against conventional waste-to-energy technologies accounting for the electricity generated and secondary resources recovery such as bottom ash utilization and metal recovery. Thus, this work focuses in using Life cycle assessment to compare and evaluate a well detailed environmental assessment of the different MSW waste to energy scenarios used in this study, provide full understanding, and sensitivity analysis of significant parameters affecting variability of the gasification waste to energy…

building stock in the year 2050 is already built [36]. Many governments and relevant communities make a lot of effort on the decarbonising in the construction industry, and BIM is at the center of controversy. BIM based technology to enhance the energy performance have improved in short period intensively over the last decade [39][43], mainly been used in the early stage of design and construction phase [3]. Efficient ways for contributing retrofit and refurbishment project still lies behind in…

Life cycle inventory(LCI), Life cycle impact assessment and finally Interpretation. Goal and scope, is the start of an explicit statement and this will set up the scope of the product. Life cycle inventory is an analysis with the goal of listing the products to and from the nature. The outcome of this is typically a flow chart. Life cycle impact assessment, is pretty straight forward given the name. This is aimed to evaluating the potential environmental impact each step from the LCI flow chart.…

Everybody has planned something in their life, for example, a holiday for good fun or a job task forms a start time to finish. From all these examples, the “plan “is used to achieve an aim and prevent potential problems before they take place. Hence this same process will apply to the IQA schematics to ensure the product and customers are on the correct path. As I mentioned in assessment 1.1 the main aspect of the quality control system is to monitor and checking the quality of a product or…

The total average of compliance across the three departments is 87%. PACU is trending at the highest compliance of an annual 96.7%. The next highest compliance is in 3E with an annual 93.5%. The immediate focus for a Plan of Action will be to correct the annual 70.7% compliance in the ED. The pain reassessment audit in on a similar trending pattern compared to the assessment audit. The same three departments, ED, 3E and PACU, are compared in the audit with a collective annual average of 80.4%.…

lessened, there would be the opportunity for larger meeting spaces, hopefully resulting in a potential rise in group participation rates. If an alternative to incarceration proves viable, perhaps these services could be offered to those populations outside of the grounds of the prison and would help to give the individuals the social context in which to apply these therapies while going through them. As an example, drug or alcohol addiction treatment within prison may initiate an individual’s…

easier for my ELL’s than it was for many native speakers. In science I would attest this to the latin and french origin of many of these terms. Idioms on the other hand were often times a great challenge for these students. I found this to be a difficult transition for me as a classroom teacher. Many of my lessons use analogies, anecdotal comparison as well as idioms to drive home may keay concepts. As a result of these interactions and at times struggles I found that a simple change in my…

Introduction High-stakes testing has consistently been a hot topic in education for decades. These tests are used to hold students, teachers, and school districts accountable for academic growth. But, what exactly is a high-stakes test? How did it evolve in education? Why does it matter? What are some of the intended and unintended consequences of high-stakes testing? Also, what arguments do the proponents and critics have about high-stakes testing? High-Stakes Tests Defined A high-stakes test…

Discussion of my own values and conclusions. Feedback on the merit of the argument, and ways it might be enhanced academically. Assessment of whether the argument is correct or incorrect, since that would be my own interpretation only. Articulation of how I believe the work is value-laden, if the values concerned are not specifically identified and the possibility of different approaches to the topic is not considered Articulation of my own values, unless for the purpose of illustrating how a…
