ENV-501: Material flow analysis and resource management

This course provides the basis to understand material and energy production and consumption processes. Students learn how to develop a material flow analysis and apply it to resource management cases. They analyze the implications of their models on resour ...

Description

This lecture covers the concepts of urban metabolism and circular economy, focusing on material and energy flow analysis for resource management in cities. It discusses the system definition of cities, accounting approaches, and examples of urban MFAs. The lecture explores the relevance of urban metabolism, system boundary definition, and different accounting approaches such as top-down and bottom-up. It also delves into the comparison of territorial/production-based vs. consumption-based accounting, policy measures at the urban scale, and the implementation of circular economy policies in cities like Brussels, Paris, and London.

Maria Anna Hecher

Maria Anna Hecher obtained her PhD degree at the University of Graz, Austria. In her recent research, she investigated regional energy transitions from a socio-technical perspective. She put a special focus on technology adoption decisions to derive strategies and policy recommendations fostering sustainable transitions. Therefore, she pursued an interdisciplinary approach and combined environmental as well as social science methods (i.e. MFA, ABM, LCA, expert interviews, surveys). After her PhD, she had the chance to put her knowledge into practice and managed a three-year programme on regional sustainabiltiy projects in an energy region in Styria, Austria. In cooperation with local decision-makers, public authorities, schools, companies and the local population, she realized projects in the field of renewable energy and sustainable mobility. Recently, she worked as a consultant in an energy agency for and in the city of Graz. She managed projects in the field of e-mobility and spatial energy planning collaborating with public authorities, energy suppliers, city planners and research institutions. Her work in recent years, has mostly been performed in an inter- and transdisciplinary setting integrating knowledge from different scientific disciplines and fields of practice at the interface between research, politics and society.

Aristide Henri Roger Athanassiadis

Aristide has a joint-PhD in Urbanism from the Université Libre de Bruxelles and The University of Melbourne on the topic of comprehensive urban environmental assessments. Since 2018, he was co-Chair of Circular Economy and Urban Metabolism at the Université Libre de Bruxelles where he advised local administrations on the regional circular economy plan and facilitated exchanges between researchers, policy makers and practitioners in order to develop projects that helped Brussels' economy and metabolism transition towards a more circular state. During the last years, he has collaborated and worked with/for several universities, research centres, environmental administrations, NGOs, youth organisations and consultancy firms on a great variety of projects around the topics of urban metabolism and circular economy. Finally, Aristide co-created the non-profit organisation and open-source initiative Metabolism of Cities (www.metabolismofcities.org) that aims to bring to create, share and apply urban metabolism knowledge, in policy and practice.

Material flow analysis

Material flow analysis (MFA), also referred to as substance flow analysis (SFA), is an analytical method to quantify flows and stocks of materials or substances in a well-defined system. MFA is an important tool to study the bio-physical aspects of human activity on different spatial and temporal scales. It is considered a core method of industrial ecology or anthropogenic, urban, social and industrial metabolism. MFA is used to study material, substance, or product flows across different industrial sectors or within ecosystems.

Urban metabolism

Urban metabolism is a model to facilitate the description and analysis of the flows of the materials and energy within cities, such as undertaken in a material flow analysis of a city. It provides researchers with a metaphorical framework to study the interactions of natural and human systems in specific regions. From the beginning, researchers have tweaked and altered the parameters of the urban metabolism model. C.

Anthropogenic metabolism

Anthropogenic metabolism, also referred to as metabolism of the anthroposphere, is a term used in industrial ecology, material flow analysis, and waste management to describe the material and energy turnover of human society. It emerges from the application of systems thinking to the industrial and other man-made activities and it is a central concept of sustainable development. In modern societies, the bulk of anthropogenic (man-made) material flows is related to one of the following activities: sanitation, transportation, habitation, and communication, which were "of little metabolic significance in prehistoric times".

Industrial metabolism

Industrial metabolism is a concept to describe the material and energy turnover of industrial systems. It was proposed by Robert Ayres in analogy to the biological metabolism as "the whole integrated collection of physical processes that convert raw materials and energy, plus labour, into finished products and wastes..." In analogy to the biological concept of metabolism, which is used to describe the whole of chemical reactions in, for example, a cell to maintain its functions and reproduce itself, the concept of industrial metabolism describes the chemical reactions, transport processes, and manufacturing activities in industry.

Sustainability

Sustainability is a social goal for people to co-exist on Earth over a long time. Specific definitions of this term are disputed and have varied with literature, context, and time. Experts often describe sustainability as having three dimensions (or pillars): environmental, economic, and social, and many publications emphasize the environmental dimension. In everyday use, sustainability often focuses on countering major environmental problems, including climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution.

Claudia Rebeca Binder Signer

Claudia R. Binder, a Swiss, Canadian and Colombian citizen, was born in Montreal and spent most of her childhood in Switzerland and Colombia. She studied at ETH Zurich from 1985 to 1996, earning a degree in biochemistry and then a PhD in environmental sciences. After conducting her post-doctoral research at the University of Maryland in the US from 1996 to 1998, she returned to Switzerland and took a position as a senior research scientist at ETH Zurich, studying the interaction between human and environmental systems at the Institute for Natural and Social Science Interface. In 2006, Binder joined the University of Zurich as an assistant professor in the Department of Geography, and in 2009 moved to the University of Graz in Austria where she served as a full professor of systems science. In 2011, she took a position at the University of Munich’s Department of Geography as a full professor of human-environment relations. Binder joined EPFL in March 2016 and set up the Laboratory for Human-Environment Relations in Urban Systems (HERUS) at ENAC; she also holds the La Mobilière Chair on Urban Ecology and Sustainable Living. Her research involves analyzing, modelling and assessing the transition of urban systems towards sustainability. She looks in particular at how we can better understand the dynamics of urban metabolism, what characterizes a sustainable city, and what drives and hinders transformation processes. She does so by combining knowledge from social, natural and data science. Her research focuses on food, energy, and sustainable living and transport in urban systems. In Switzerland, Binder was appointed to the Research Council, Programs Division of the Swiss National Science Foundation (SNSF) in 2016 and serves on the Steering Committee of the SNSF’s National Research Program 71, “Managing Energy Consumption” and the Swiss Competence Centers for Energy Research (SCCER). She is also a member of the Steering Board on Sustainability Research for the Swiss Academies of Arts and Sciences. In 2019, she was elected as a member of the University Council of the University of Munich (LMU). At EPFL, Binder is the academic director of Design Together, a cross-disciplinary teaching initiative. She was appointed to the management team of the Energy Center in 2018 and as head of the working group on EPFL’s energy and sustainability strategy in 2019.
