Life cycle assessment essay

In fabrication phase, gold metal is used in this merchandise, which can do major impact on the environment as it produce Kg CO2emanations. A critical need in the area of life-cycle assessment methodology as applied to wood as a raw material, therefore, is to develop means for explicitly considering the range of potential and actual environmental impacts associated with forest management practices.

For example, reducing the use of paper can generally provide major environmental benefits, but even after aggressive use reduction, businesses still use significant quantities. Indeed, the omission of forest management issues is usually explained by invoking the difficulty of integrating into the analysis the admittedly more qualitative nature of many such Life cycle assessment essay.

These impacts can include damage to forest soils and productivity, water quality and aquatic habitat, plant and animal habitat and diversity, and the preservation of important natural forest communities and ecosystems.

Because an increase in the use of recovered fiber by paper mills means a lower requirement for pulpwood, recycling extends the fiber base and can help to conserve forest resources. Second, single measure of stress should be selected. The battery of this merchandise is rechargeable lithium battery.

Considering all Aspects of Fiber Acquisition Obtaining the fiber to make paper products—whether derived from used paper collected for recycling or from trees—entails a range of environmental impacts. The remains of coffee grounds put in trash often end up in regional solid waste facility.

Significantly, such information is not only relevant in assessing the relative merits of recycled versus virgin fiber content, but also in identifying environmental preferences among different management practices used to produce virgin fiber.

It was designed to provide a guide to wise management of human activities by understanding the direct and indirect impacts on ecological resources and surrounding ecosystems.

Life-cycle assessment

The liquid dripping out of the filter is consumed. This is sometimes referred to as the boundary critique to systems thinking.

This means not just examining differences in recycled and virgin manufacturing processes and in waste disposal versus material recovery systems, but also considering the "upstream" impacts associated with acquiring virgin fiber from forests.

This papers will incorporate some background information belong to the LCA and merchandise. Thus during rapid growth the industry as a whole produces no energy because new energy is used to fuel the embodied energy of future power plants.

The model evaluates the impacts of fuel use using a well-to-wheel evaluation while a traditional cradle-to-grave approach is used to determine the impacts from the vehicle itself. Our methodology for two specific categories of environmental parameters—energy use and emissions of greenhouse gases—merits further elaboration.

To omit those impacts entirely from an assessment of paper products, however, produces a greatly distorted picture—one that is systematically biased against paper products that incorporate recovered fiber.

For the virgin-fiber-based system, we included harvesting of trees and transport of logs or chips to the mill, debarking and chipping, manufacture of pulp and paper using virgin fiber, collection of the paper after its use as part of municipal solid waste MSWtransport of the waste to MSW landfills and waste-to-energy incinerators, and disposal or processing of the waste at such facilities.

The accuracy and availability of data can also contribute to inaccuracy. The longer the ground coffee stays in contact with hot water, the more the extraction of the coffee oils and flavor is.

The tabular array below explains all the packaging stuff used in retail and transportation. In using this approach, the task force has provided a way for purchasers to address all of the major environmental impacts of their paper use.

The systems approach allows an assessment of the full range of environmental consequences that follow from the choice to produce recycled-content paper and recover and recycle used paper, as opposed to producing virgin paper, disposing of it and replacing it with new virgin paper.

Life Cycle Assessment

Last, stress selected in step 2 is used as standard to assess phase of life separately and identify the most damaging phase. Our methodology for two specific categories of environmental parameters—energy use and emissions of greenhouse gases—merits further elaboration.

Each system includes analogous activities in the acquisition of fiber, pulp, and paper manufacturing and disposal of residuals. Full elaborate study of the impact of each phase is attached in the appendix. The use phase and disposal phase of the product are omitted in this case.

The system boundaries of analysis include: The battery used in this theoretical account is Lithium-ion polymer, 38 Whr [ 5 ]. Harmonizing to the informations in the tabular array, the major impacts is coming from the gold, circuit board and battery.

Some phases were excluded in this survey such as transporting natural stuffs to the processing installation.

Impact appraisal is gauging the environmental impacts based on the consequences of the stock list analysis.

Packaging, and disposal have least impact or load on environment. Collection and processing of recovered paper—activities that are typically extensively analyzed in life-cycle studies of paper products—requires energy and can release pollutants to the environment.

Coffee grounds compost relatively fast owing to the small size of individual coffee grounds. Composting of the remaining coffee grounds helps in enriching the nitrogen content of particular compost. The average production of coffee per one hectare varies depending on the characteristics and types of the land for cultivation and a number of ecological factors such as the age of the coffee plants.

Environmental Impact Life Cycle Assessment of a Laptop Essay

In the United States, landfilling is used for about 80 percent of the MSW that is not recycled, while waste-to-energy incineration accounts for virtually all of the rest Franklin Associates, Life Cycle Assessment is a process to evaluate the environmental burdens associated with a product, process, or activity by identifying the quantity of energy and materials used and wastes released to the environment; and being able to assume the damage it causes to the environmental issues.

This Life Cycle Assessment (LCA) aims to evaluate the environmental impact of the production of candlesticks. All the different materials and processes required to manufacture candles need to be taken into consideration to determine the impacts on the environment.

 Life Cycle Assessment ENMN Instructor: Will Low Erkens Gjini, August 10, Life Cycle Assessment (LCA) is a tool for the systematic evaluation of the environmental aspects of a product or service system through all stages of its life cycle.1Understanding the environmental impacts of your operations, products, services or technology will improve humankind’s relationship to the.

Life Cycle Assessment Deliverables: 1. Case Study Report 2. Information Sheet: This is a technical summary of the most relevant information of your research. See example “BSCInfo__Cavity_Insulation_ Information sheet”.

Life Cycle Assessment (LCA) is a technique that is used to assess every impact associated with the stages of a process from cradle-to-grave. It is a holistic approach to evaluating environmental effects of a product, process or activity by looking at the entire life cycle of the product, process or activity from the extraction of raw materials.
