Nothing is lost, nothing is created, everything is reused: structural design for a circular economy

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting

Structural designers’ efforts to reduce environmental impacts traditionally consist of developing systems that minimise material quantities or use low-impact materials. A third strategy is currently (re)emerging: the reuse of structural components over mul ...

Combined exergy analysis, energy integration and optimization of syngas and ammonia production plants: A cogeneration and syngas purification perspective

François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma

Modern ammonia production plants are equipped with efficient energy integration networks able to recover an important fraction of the waste heat exergy available throughout the chemical system. However, in order to drive the endothermic reforming reactions ...

A Mixed-Integer Linear Programming Formulation for Optimizing Multi-Scale Material and Energy Integration

François Maréchal, Ivan Daniel Kantor, Hür Ebuzer Bütün, Jean-Loup Sylvain Robineau

This research presents a mathematical formulation for optimizing integration of complex industrial systems from the level of unit operations to processes, entire plants, and finally to considering industrial symbiosis opportunities between plants. The fram ...

Comparison of environmental assessment methods when reusing building components: a case study

Corentin Jean Dominique Fivet, Endrit Hoxha, Catherine Elvire L. De Wolf

The building industry is responsible for 35% of all solid waste in Europe and more than a third of greenhouse gas (GHG) emissions. To address this, applying circular economy principles to the building sector is crucial, for example by reusing building elem ...

The Scale-Dependent Behaviour of Cities: A Cross-Cities Multiscale Driver Analysis of Urban Energy Use

Franziska Meinherz, João Vitor Meirelles de Miranda, Aristide Henri Roger Athanassiadis

Hosting more than half of the world population, cities are currently responsible for two thirds of the global energy use and three quarters of the global CO2 emissions related to energy use. As humanity becomes more urbanized, urban systems are becoming a ...

Exergy assessment of future energy transition scenarios with application to Switzerland

François Maréchal, Daniel Favrat, François Richard Vuille, Victor Codina Gironès, Matteo Allais

Using an exergy based indicator is highly desirable to compare future national energy strategies. A new web- based information platform called energyscope.ch, informing the general public on the Swiss energy transition was presented at ECOS2016. This paper ...

Malfunction diagnosis of thermal power plants based on advanced exergy analysis: The case with multiple malfunctions occurring simultaneously

Ligang Wang

During continuous operation of energy systems, the performance of components will mostly, gradually deviate away from the reference conditions due to performance degradation, which may eventually lead to malfunctions or operation failure. The complex inter ...

Combined Exergy Analysis and Energy Integration for the Optimization of Nitrogen Fertilizer Plants

François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma

Modern ammonia production plants are equipped with efficient energy integration networks able to recover an important fraction of the enthalpy of reaction released by the exothermic chemical systems. However, to fully supply the exergy demands of the highl ...

Environomic multi-objective optimization of an eco-industrial park

François Maréchal, Maziar Kermani, Lindsay Dianne Lessard

A circular economy refers to an industrial economy with a cradle to cradle vision, shifting from the use of fossil fuels towards renewable energy, minimizing the use of toxic chemicals and reducing waste by recycling through careful system design. The conc ...

Defining Ecological Strategies in Neuroprosthetics

Grégoire Courtine, Jocelyne Bloch

Neurological disorders disrupt the equilibrium within the brain and spinal cord ecosystems. Ecology reuses, recycles, and reduces to help maintain the balance across ecosystems. Likewise, neuroprosthetics can help the brain help itself with ecoprosthetic d ...

Defining “Waste Heat” for industrial processes

Daniel Favrat, François Maréchal, Matthias Bendig

This paper aims at presenting a method for identifying, characterising and quantifying the available waste heat of an industrial system that can be converted into a useful form. A distinction is made between avoidable and unavoidable waste heat. This disti ...

Thermodynamics and the optimisation of energy systems: Strengths and Limits

Daniel Favrat

The Second Law of thermodynamics is known to be an essential guide for the improvement of energy conversion systems. Throughout the years it has been applied to various engineering methods in particular in methods based on exergy [1] including the 2nd Law, ...
