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, Johor Darul Takzim.

The Life Cycle Assessment (LCA) has the obvious advantage of revealing potentially significant but hidden environmental impacts. Instead of focusing attention on large, concentrated and readily apparent point sources of impacts.

2.2.1 History of Life Cycle Assessment (LCA)
As we all know, the Life Cycle Assessment (LCA) is an effective framework to analyze the whole process of a product. The first attempt to look at extended product systems can be traced back to as early as the 1960s. This work mainly focused on calculating energy requirements. Several such fuel cycle studies were conducted in the United States by the Department of Energy. Although they focused on energy characteristics, these studies also included limited estimates of environmental releases.
With the oil shortages in the early 1970s, both the U.S. and British governments commissioned extensive studies of industrial studies to conduct detailed energy analyses.

Then, it is left to form Franklin Associates Ltd. Activity in the United States on environmental LCAs continued at a slow but steady, pace of around two or three studies per year. The exact number is not certain because most studies were performed for private clients and not released for public …show more content…

It explicitly outlined the components of contemporary LCA: goal definition, inventory assessment, impact assessment and improvement analysis.

2.2.2 The Product Life Cycle
The life cycle a generic industrial product was defined by SETAC, 1991 as being composed of the following stages: (a) Raw Material Acquisition All activities necessary to extract raw material and energy inputs from the environment, including the transportation prior to processing.
(b) Process and Manufacturing Activities needed to convert the raw material and energy inputs into the desired product. In practice this stage is often composed of a series of substages with intermediate products being formed along the processing chain.
(c) Distribution and Transportation Shipment of the final product to the end user.
(d) Use, Reuse and Maintenance Utilization of the finished product over its service.
(e) Recycle Begins after the product has served its initial intended function and is subsequently recycled within the same product system (closed-loop recycle) or enters a new product system (open-loop

It is imperative to understand the current conditions of what materials are candidates for return, compared to the performance level of returns achieved each day. The delta between the identified material returns and the actual returns will provide information for goal setting. Additionally, with the transfer of raw materials into the warehouse, there must be a transaction to receive it into inventory and distribute it to the appropriate location. At that point, the process will be complete for the appropriate accounting of the materials, creating availability for consumption at the next production demand. The data collected will be influential in developing a robust procedure for each assembly line to follow in a consistent manner.

The energy crisis began after OPEC seized oil production because of the, “anger at the United States for aiding Israel.” (Farber, 22) This caused a mass panic amongst Americans and resulted in long waits to get gas and constant fuel outages. Carter was extremely adamant that Americans reduce their consumption of fuel in order to reduce the extent of the energy crisis, at one point suggesting putting heavy penalizing taxes on non-fuel efficient vehicles. Political journalist Nicholas Lemann recalled, “[The energy crisis was] the automotive equivalent to the Depression’s bank runs.”

Thomas Walsh was born in 1952 while the United States was still recovering from major political and economical crises that took place in the decade before. Many of these events were war related, including World War II, the Cold War, and the attacks on Pearl Harbour. The economical crises caused severe poverty as seen in the Great Depression and with inflation. Between the years 1942-1952 the American people suffered a lot of damage from war, but also prospered greatly in social aspects with new media and attractions. World War II began a year before Roosevelt was elected into his third presidential term in 1940.

Executive Summary Mature and Cyclical Product Market The mature market is the third stage in the product life cycle that the sales reach their peak (see Figure 1) and the market becomes saturated as there are fewer new customers. The majority of the consumers who are ever going to purchase the product have already done so. In a mature product market, there are the highest levels of competitions that many companies are competing for a share of the market. The product category is well-known, which is no longer making the news.

Vertical Integration When we say that an organization is engaged in vertical integration, we imply that the organization is in charge of two interweaved steps of the manufacturing or value chain process. The manufacturing or quality chain procedure is the series of changes that raw materials undertake until they are changed into finished product. Sometimes this series is not in only one chain, e.g. some products are the resultant of two distinctive middle products. Going by this we can have three potential outcomes of vertical combination: (a) Backward or upstream integration; (b) Forward or downstream integration; (c) Lateral integration Practically it is difficult to distinguish lateral and backward integration; many research material

What is an environmental impact report or statement? When we think of engineering we usually think of the construction of buildings or roads or even the manufacture of products. We rarely consider what effects these processes have on the surrounding environment or the global impact. In this section of the report I will discuss why an Environmental Impact Statement and Environment Impact Assessment are used in Civil engineering.

One of the foundations of sustainable development is efficient environmental management (UNEP 2002). However, balancing the needs of current generations without compromising the environment for future generations poses to be quite problematic. A number of environmental decision-making instruments have been developed in an attempt to ensure that development is sustainable. One of the most popular of these is environmental impact assessment (EIA). This essay will be based on the strengths and limitations of an Environmental Impact Assessment.

2.5.6 Life Cycle Theory "The basic premise of the theory of the cycle of organizational life is that the firm in a manner similar to living organisms, progressing through a number of stages of life, beginning with birth and ends with death" (FRIELINGHAUS et al., 2005, f. 9). According to authorities, the life cycle of a business affects the capital structure of a firm, because the transition from one stage to another, financial needs can be different (Adizes, 1979, p. 4). The progress of a business or product passes through successive stages, starting from the origin until his inevitable fall. Life cycle phases typically include: conception (birth), rapid growth, expansion into new markets, maturity and decline at the time when falling consumer
