Summary: Patricia Osseweijer is full professor and leader of the Biotechnology and Society Section at Delft University of Technology, Faculty of Applied Sciences. She has a Master of Science in Biology (University Utrecht) and a PhD in Science Communication (VU Amsterdam). Her drive is to link technological innovation in sustainable biobased production and water systems with societal development for a sustainable and circular (bio)economy, addressing Sustainable Development Goals. Her multidisciplinary group works on designs of novel value chains for biofuels, bioproducts and circularity, focusing on integral impact assessment, inclusive innovation, social sustainability, co-creation, public perceptions, communication and ethics. In 2015 she received the (NL) Royal Academy distinguished Lorentz fellowship for integrating social sciences & technology. Patricia is University Ambassador Brazil and coordinator of the 19 M Euro EU-Horizon2020 funded Water-Mining program with 39 public private partners developing demonstrations on nutrient recycling and water recovery for circular water management in several venues in Europe.

Summary: In his talk, Benjamin will provide an overview of his theoretical research, related applications and the research (and non-scientific) environment in Germany. He will introduce the core concepts of molecular thermodynamics and outline the pathway from molecular interactions to the thermodynamic properties of solid-fluid systems – properties that are essential for many technological applications. Benjamin will then discuss three molecular models: Classical density functional theory (DFT), which allows to calculate equilibrium properties such as contact angles and solvation free energies. Second, the concept of entropy scaling is used to determine transport properties including viscosity and diffusion coefficient. Third, hydrodynamic DFT is a continuum approach based on balance equations, similar to the Navier-Stokes equations, which accounts for the effect of solid-fluid interfaces on flow within a porous system. Finally, a process model for CO2 capture using adsorption is briefly presented, which relies on molecular models for the adsorption isotherm, thereby connecting molecular models and typical engineering approaches.

Benjamin Bursik is a Ph.D. candidate in the field of molecular thermodynamics at the Institute of Thermodynamics and Thermal Process Engineering (ITT), at the University of Stuttgart. His research focuses on developing theoretical models to study fluids in porous media. Starting from the interactions of individual molecules, he investigates dynamic processes that are relevant in a variety of applications, such as fuel cells, underground water systems or biological tissue. Currently, Benjamin is conducting a three-month research stay with Prof. Luis Franco’s group, where he applies molecular models to adsorption processes for the capture of CO2 from exhaust gases. His master thesis at ITT involved deriving a model for surfactants, which are commonly used in soaps or as emulsifiers. As an undergraduate, he spent one year at the University of California, Berkeley, broadening his academic experience in thermodynamics and fluid dynamics.

Summary: Rebecca will introduce the Stanford Doerr School of Sustainability and highlight the importance of real-world data in sustainability research. During her talk, Rebecca will talk about opportunities for cooperation between Stanford and UNICAMP. She will then discuss TASTE Food, an open-source tool designed to categorize food purchases and streamline the process of estimating food-related emissions. This tool helps institutions improve consistency and comparability in emissions calculations. The second half of the talk will focus on commercial building HVAC systems, exploring low-cost strategies to optimize air conditioning set points in older buildings with limited controls. By leveraging climate data and experimental results, the talk will demonstrate how targeted adjustments can improve energy efficiency and reduce cooling demand.

Rebecca Grekin is a Ph.D. candidate in the Energy Science & Engineering Department (ESE) at Stanford University. Rebecca is passionate about using real-world data to develop tools and methods to quantify and mitigate emissions. Rebecca’s Ph.D. focuses on identifying low-cost opportunities for more efficient and flexible energy consumption of existing commercial building stock by modifying Heating, Ventilation, and Air Conditioning (HVAC) operations using location and weather-dependent parameters instead of the generic rules of thumb commonly used in HVAC systems. For her Masters, also in ESE, Rebecca developed software, which is available online for free, to calculate emissions from food purchases for Scope 3 purchased goods emissions analyses. Before Stanford, Rebecca earned her Bachelor’s degree from MIT from the department of Chemical Engineering with a Minor in Sustainability & the Environment.

Summary: Circular economy is frequently promoted as the answer to the growing problem of waste (e.g. biomass residues or plastic waste), however there is great discussion regarding the appropriate technologies to facilitate this transition. In this presentation, Dr. Luis Cutz will make the case that thermochemical conversion has great potential to revolutionize the way we now handle waste. Thermochemical processes face numerous obstacles, such as their high cost and energy requirements. A potential solution could lie in the development of novel catalysts and solvents that streamline downstream separations, lower operating conditions, and make waste valorization economically viable. Optimizing waste utilization presents a dual opportunity: it enables the production of multiple products from a single source while addressing the pressing health and environmental challenges faced by regions burdened by waste.

Dr Luis Cutz is an Assistant Professor at the department of Process & Energy, Faculty of Mechanical Engineering at TU Delft in the Netherlands. He develops thermochemical technologies to convert waste materials into chemicals, biofuels or new raw materials. These products can serve power generation, transport fuels, horticultural applications, batteries and a source to manufacture new polymers. His research group develops experimental methods to study and optimize the conversion of plastic waste/biomass from micro to macroscale. This approach allows them to scale processes from simulation to laboratory scale.
