Abstract
Product is the lifeblood of enterprises. The only way to sustainable business is to promote the environmental design of green products. The World Enterprise Sustainable Development Committee (WBCSD) advocate eco-efficiency to be the evaluation index of an enterprise sustainable development; and product eco-design (Ecodesign) is the opportunity of leading the enterprise into the eco-efficiency environment.
Under the Eco-efficiency assessment framework, this study explores in two aspects. First, the positive efficiency of a product′s superior function or service value, which contains the characteristic of various criteria in decision-making, and utilize the analytic hierarchy process (AHP) to study and analyze the function attributes of the product. Second, the assessment of the environmental impact to the product, due to the nature of environmental impact in each stage during the product life cycle, using the product life cycle software to evaluate, in line with the legal regulation and broad range of database, can all become the assessment infrastructure of the Eco-efficiency.
The collection of Headset functional attributes needs to establish objective evaluation of the screened assessment as follows. Appearance, usability, functionality, advanced demand, price five major facets; as well as Wearing Style, Weight, Volume, Material, Driver monomer, Impedance, Sensitivity, Sales Price, Product Marketing Appeal, Frequency Response, Adjustment Mechanism, Product Modeling, Anti-noise Level, Bluetooth Wireless, Storage and Packaging, and Material Costs sixteen functional attributes.
Produce expert questionnaire and perform expert questionnaire survey, collect valid questionnaires to calculate its quantitative value with Analytic Hierarchy Process (AHP). In addition, objectively proceed standardize calculation, and the total of the weighted score of the Five major Facets, to obtain the Headset product comprehensive function evaluation value; the Headset product comprehensive function evaluation value is the Numerator of Eco-efficiency framework. The Denominator is the use of PRé SimaPro software to perform headset product life cycle analysis. In the process, the chart illustrate the environmental effect of related products’ materials, manufacturing processes, transport packaging and its recycling usage; at last, using the simple Division calculation to obtain the Product ecological efficiency value; also apply Comparative analysis to the case study headsets.
Enterprises produce mass products but not recycle any of the resources, and create tremendous litter. This becomes a disaster to the earth resources. More and more companies paid their attention to this issue. There are two strategies to resolve this issue: the first one is to reduce the use material, energy, although there are more and more high efficient energy technologies, however, this can only slow down the time line of exhausted the resources. The current practice of resource re-use, reduce consumption, and recycling is only to minimize the damage. Another strategy is to rethink the method of manufacturing, the efficiency of using materials, and by improving the quality to create superior products, transform the litter and waste become material.
Product life cycle assessment is not just from “Cradle to Grave”, but from “Cradle to Cradle”. Enterprises, by its innovative products, segregated from the general market; not only reduces cost, increase profits, but also Implement the product design concept, and lead the enterprise to sustainable development. | en_US |
