The thesis proposes the development of a methodology for the metrification and monetization of the life cycle of an industrial product, and its validation by its application to an actual case: a comparison between two types of disposable packaging, cups of raw materials from renewable sources (cassava/manioc) and plastic cups. The motivation of the study is the finding that the industrial system throughout the life cycle of the product until its consumption and disposal, has yet to adopt a circular model of production that maximizes reuse and recycling of waste as well as limiting the emission of greenhouse gases, excessive water consumption and disposal of waste, factors that threaten planetary sustainability. These threats arise as a shared responsibility between society and government, reflected particularly in the National Solid Waste Policy of Brazil. For companies, it is necessary to measure and value the full product cycle, earth to earth, including reverse logistics, extended product responsibility, and environmental cost. In this sense, equations were developed for metrication and monetization of the product cycle. For validation, company data were used from CBPAK, a manufacturer of cassava cups, and BRASKEM, a raw material producer for the plastic packaging industry. The study concludes that the methodology is valid and can be replicated. The comparison between the cups from the two sources shows environmental indicators largely favorable to cassava cups and, from a financial point of view, the application of full life cycle shows a cost equalization of the order of 60 per cent compared to prices without consideration of externalities.
