Abstract

Abstract. The aim of this paper is to assess and evaluate the environmental impact during the manufacturing process of Liquid Cristal Display (LCD) monitor of personal computer.  Life cycle assessment  (LCA) is utilized to evaluate the environmental impact during the manufacturing of LCD.  The environmental load is expressed by Eco indicator 99 method.   The damage categories based on Eco Indicator 99 consist of 11 categories, carcinogenic, respiratory inorganic, climate change, ionizing radiation, ozone layer depletion, Eco toxicity acidification/eutrophication, land use, extraction of mineral, and extraction of fossil fuels. Furthermore the environmental load is divided by  three categories, which are human health, damage of ecosystem and depletion of resources. Simapro software version 8 is applied to calculate the environmental load each component of LCD display personal computer product. Finally, the result showed that the largest environmental load during the manufacturing process of a LCD computer display is to human health, followed by damage of ecosystem and the depletion of resources. Also, PWB component part of LCD monitor has the largest contributor for degradation environmental performance during the manufacturing process of monitor LCD, following by production of metal and plastic.

Abstract

The aim of this study is to develop a conceptual framework for assessing and minimzing industrial waste. A conceptual framework is developed by integrating Life Cycle Assessment (LCA) tool and cleaner production method. LCA is utilized to evaluate and identifi  industrial waste along the life cycle of product/services . On the other hand,  cleaner production method is implemented for mitigation strategy to minimizing the most significant waste along industrial activities. By using LCA, the significant waste will be identified. Furthermore, cleaner production will be implemented to the significant waste to improve the environmental performance of industries activities. Cleaner production strategies such as product modification, Input substitution, technology modification, reuse/recycling, and good housekeeping are applied to prevent industrial waste generation. Furthermore, the integration betwen LCA tool and CP method significanly improve the environmnetal performance  during the industrial activities. CP and LCA were succesfull for improving environmental performance in term of raw material saving, water saving, energy saving and wastewater reduction.
