ecoPROSYS: An eco-efficiency framework applied to a medium density fiberboard finishing line

摘要

Assessing eco-efficiency performance of a production system is of great importance, since such assessment enables one to make an informed decision concerning economic and environmental performance of elementary systems within industrial productions systems. The framework presented in this paper is based on the eco-efficiency principles and four cornerstones i) Data inventory, ii) Environmental performance evaluation, iii) Environmental impact assessment and iv) Cost models/Value data. The Eco-Efficiency Integrated Methodology for Production Systems (ecoPROSYS) approach relies on the use of a systematized and organized set of indicators easy to understand/analyse promoting continuous improvement and a more efficient use of resources and energy. The goal is to assess eco-efficiency performance in order to support decision and enable the maximization of product/processes value creation and minimization of environmental burdens. The methodology was applied to a Medium Density Fibreboard (MDF) finishing line. The results of the study intend to validate the applicability of ecoPROSYS. The case study showed that the cutting and the feeding table have superior eco-efficiency performance while packing and sanding have lower eco-efficiency performance. The presented framework is a powerful tool that can be used to identify and quantify key variables, assess alternative scenarios, evaluate environmental aspects, environmental influence and assess unit processes and overall eco-efficiency performance.
