Industry 4.0 methodological advancements based on continuous analytics and on the sensorization of manufacturing lines make it possible to design and develop integrated systems for measurement and verification of the impact of implemented energy conservation measures (ECM) in industrial plants. The pilot study presented here has focused on developing a model of the energy consumption of the injection...
The automotive sector is organized for mass production of complex products. Therefore, the reign of a dominant design is ineluctable. Nevertheless, carmakers shall bring to the market ground breaking products. How to solve this paradox? How to invite ideas, delve deeper into the best ones, conceive ground-breaking innovations and bring them to life in realistic prototypes? Renault proposal is to enable...
In the urge to make solar energy competitive enough to directly face fossil fuels, several approaches result crucial for their intended capacity to maximise the energy that can be produced with a given photovoltaic area. Low Concentration Photovoltaics (LCPV) and tracking methods can be integrated in V-Trough solar devices to increase their effective solar harvesting area through low-cost non-imaging...
Water use impact assessment, also named water footprint, has an increasing interest and thus methodologies are quickly evolving within the frame of life cycle assessment. In this work, we proposed to apply an adaptation of Ridoutt and Pfister (Int J Life Cycle Assess 18(1):201–207, 2013) methodology to address both consumptive and degradative use of water for several options of urban water cycle management...
The concept of eco-maintenance aims to prolong the lifetime of the system to maintain while minimizing environmental losses due to maintenance. This concept is developed for renewable energy production system (Reps) like wind turbines or photovoltaic panel. REPS generate clean and inexhaustible energy. However the production of this energy is unpredictable because it depends on the weather. Moreover...
A methodology is developed for assessing relevant issues of the environmental, economic, and social dimensions of the modern sustainability concept. It is designed for evaluating and selecting materials and technologies during product development. Established approaches, i.e. environmental life cycle assessment, life cycle costing, social life cycle assessment, material flow analysis, and the “criticality”...
A mathematical model of emissions was developed in a Twingo D7F engine. The effects of variations in compression ratio, fuel/air equivalence ratio, spark advanced and combustion duration under pollutant emissions were studied. Analysis and data collection were performed in an engine bank using a data acquisition system integrated to an Interactive Engineering Environment. A control strategy was implemented...
This paper proposes a framework that interrelates the life cycle of the product, remanufacturing and recycling for plastics. The paper analyses the different chemical processes of recycling polymer wastes. We introduce a thermodynamic calculation of the energy consumed and CO $$_2$$ 2 emissions for all types of waste (municipal, electronic, vehicle). The remanufacturing process could reduce...
The French network Eco-design of Sustainable Systems (EcoSD) has initiated collaborative research projects in order to foster collaborations between academic and industrial partners. Two projects concerning eco-innovation processes, methods and tools have been carried out between 2012 and 2014. This paper first offers a synthesis of the projects, and questions the new directions to feed research in...
Usage ecodrifts, which refer to non-optimal use of a product by the users, create additional environmental impact generators: energy overconsumption (real-time impacts) and abnormal wear and tear of parts of the product (delayed impacts). The goal of this study is to demonstrate that these Usage EcoDrifts must be taken into account during the design stage to better the environmental performance of...
Faced with increasing regulatory and social pressures, the industrial world must offer safer and more environmentally services while maintaining economic competitiveness. Thus, the development of sustainable activities is essential, and new interactive approaches to evaluate them are needed. In this context, the purpose of this study is to develop a methodology to analyse and compare the sustainability...
Companies are still struggling to implement ecodesign in their daily product development processes. It is believed that this occurs because companies should firstly improve their strategy and management skills towards sustainability before introducing any ecodesign tool. As a consequence, this paper aims to propose a self-evaluation framework to rank companies into different classes according to their...
Human activities on the building floor can cause vibration which is potentially disturbing for occupants. This kind of vibration could be useful in energy harvesting. One of the most important devices for energy harvesting is piezoelectric materials. In this paper the energy harvesting of a five-story wooden building vibration using piezoelectric materials is developed and a new fixture is designed...
