Case studies are reported on the life-cycle assessment of biopolymers used in several sectors with a major focus on the building sector. accuracy of system models. A brief historical digression is presented. However, the study of eco-efficiency is still no easy task, despite recent studies and publications, as no uniform, generally accepted definition and framework for its measurement is available, and it is focused on eco-efficiency at company level. This helps answer a central question from a societal point of view: what environmental improvements can be achieved for the money invested? where machine productivity and quality often has a higher weighting than In this case study, the comparison of two different mold designs (cold runners and hot runners) clearly shows that the mold design with hot runners would be the best in terms of eco-efficiency, as the value is higher for this design alternative, and the impact of material consumption is lower due to the lower levels of material and energy consumption. when the stator currents are synchronized with the rotor motion to maintain This specific focus implied the necessity to introduce specific—unit-, period-, life cycle phase- and life cycle-related—value indicators for enabling a comprehensive evaluation of product performance. It presents a typical preparative method for industrial painting based on biopolyester. Eco-efficiency is achieved through three objectives: Reducing environmental impacts (Government of Canada, 2013). J.
