106 Life Cycle Assessment for innovative and environmental friendly designer lamps A. Evangelio and M. Faragò DTU Environment, Technical University of Denmark INTRODUCTION Increasing is the attention of the public in creating less environmentally impacting products and services. Life Cycle Assessment (LCA) is the tool that quantitatively assesses which is the environmental impacts related to all the stages of a product’s life. The aim of this study is to apply LCA to two different innovative designer lamps made of two types of materials: lamp 1 of powder-coated steel and zinc and lamp 2 of polished brass (Figure 1). Figure 1: From the left, Powder coated (zinc) steel and polished brass lamps. THEORY The theoretical approach of this study is to perform not only a life cycle check of the lamps but also to use the LCA cradle-to-grave approach to evaluate the environmental impacts along all the phases of the life cycle including material, manufacturing, distribution and disposal of the 2 lamps. Based on the results of the LCA, a recommendation on which material is more “environmental friendly” is made in order to help the commissioner to choose the material for production. METHODS AND RESULTS The methods include goal and scope definition of the project, system boundaries assessment, inventory analysis of all the processes included in the assessment, final environmental impact assessment and sensitivity analysis. Results show that the steel lamp has the lower environmental impacts in all the stages of the life cycle. In short, in table 1 the normalized endpoint categories impact scores are presented.
