Evaluation of the productive and environmental potential of closed-loop manufacturing process

Nowadays, energy is considered, and in the future, the main factor for manufacturing. Therefore, closed-loop production processes can reuse waste or by-products, but they have high electricity consumption and generate high rates of pollutants. This scenario is contradictory when looking for the eco-efficiency of the production plant. In this sense, this article aims to develop a theoretical model that optimises solutions to raise the productive and environmental performance of manufacturing. The modelling made compatible the improvements of the system through the inventive principles (theory of inventive problem solving – TRIZ) with environmental analysis (life cycle assessment – LCA) for the generation of systematic innovations in the manufacture. The experimental results present an architecture of results for the use of thermochemical routes and alteration of the composition of the productive resources for generation of clean energy and reduction of the environmental impacts.
