SYSTEMIC ANALYZE BY LIFE CYCLE INVENTORY OF THE HYDROPHOBIZATION UNIT PROCESSES FOR TEXTILES

Abstract

This paper presents aspects regarding life cycle inventory (LCI) of the classical hydrophobization process used in textiles finishing. According to the ISO 14040-14044 stardards used for determine the framework for conducting an LCA (life cycle assessment), there are 4 steps for obtaining an LCA – scope definition, LCI, LCA impact, LC (life cycle) interpretation. In our work, we analized warming impact generated by gases, water footprint and energy impact. For analyzed sample (bbc 100%), treated with NUVATTC (based on fluorocarbon) for obtaining hydrophobic effect, was analyzed the LCI and the process tree. The goal was to obtain the environment impact level for classical hydrophobization based on fluorocarbon. The research methodology consisted in collecting technical input and output data and using the SimaPro software for generating the LCI. We obtained the input data (raw material, energy, chemical substances and water consumption) by direct measurements on machinery, device logs and specifications of the equipment (technical books) and processes. The output data (waste energy, water and chemicals were obtained using statistics, internet databases and SimaPro software. The environmental impact categories identification (carginogenic, inorganic compounds upon the breath, climate change, radiation, ozone layer, Eco-toxicity, land use, minerals and fossil fuels) was done by using the method ECO indicator 99. This study shows that the process of classic hydrophobization has a negative impact on significantly on climate change, fossil fuels, ozone layer and effects of inorganic compounds upon the respiration, and all this is the consequence of the chemicals, based on fluorocarbon, use.
