Recycling of Inorganic Materials
A sustainable future depends on closing material loops across all sectors. We design and optimize technologies for recovering and reusing both inorganic and organic resources—from metals and minerals to textiles and polymers. By integrating recycling innovation with material flow analysis and circular economy modeling, we create systems that maintain product quality while reducing waste and emissions. Our goal is to turn end-of-life products into new beginnings, ensuring that every material retains its value and function within a regenerative, low-carbon economy.

| Abstract | The textile industry urgently needs solutions to reduce waste and reliance on virgin materials. Our research develops innovative chemical and biochemical recycling methods that break down textile fibers into reusable raw materials. Using catalytic and enzymatic processes, we recover valuable components like cellulose, polyester, and dyes. These processes support closed-loop textile production, allowing fibers to maintain their quality and function across multiple life cycles. By combining process innovation with environmental assessment, we contribute to sustainable pathways for the future of circular textiles. |

| Abstract | This project supports the vision of a sustainable textile economy by exploring how design, materials, and business models can enable circular fashion. We combine technological, economic, and social approaches to promote responsible and resource-efficient production. Our research focuses on bio-based fibers, fabrics designed for recyclability, and digital tools for tracking products and promoting reuse. By connecting science, industry, and design, we aim to build fashion systems where materials circulate, waste is minimized, and sustainability becomes the rule—not the exception. |

| Abstract | To build a sustainable and circular economy, industrial processes must be designed for minimal waste and maximum resource reuse. This project develops thermochemical processes that transform waste materials and by-products into valuable feedstocks and energy carriers. By integrating heat recovery, carbon recycling, and material valorization strategies, we aim to close industrial loops and reduce overall environmental impact. The approach combines experimental research, process modeling, and life cycle assessment to create solutions that are both technically and ecologically sound. |

| Abstract | Dielectrophoresis (DEP) is investigated as a separation technology for recycling waste from electrical and electronic equipment (WEEE). DEP enables particle separation based on size, shape, and material properties and is well established in microfluidic systems. Recent work demonstrates that DEP filtration can be scaled to high-throughput operation and applied to lithium-ion battery (LIB) waste streams. However, the governing mechanisms of DEP filtration under industrially relevant conditions are not yet fully understood. This project combines experimental studies with CFD simulations to analyse DEP-driven particle transport at high throughput and to characterise the polarisation behaviour of particles typical of LIB waste. The results support the development of a DEP-based unit operation that can be integrated into existing WEEE recycling processes to improve material recovery and reduce chemical consumption. |

| Abstract | Understanding how materials move through cities, countries and industries is key to creating sustainable systems. We use advanced material flow analysis (MFA) to model and map resource cycles and identify recovery potentials in urban and rural environments. By establishing and linking data on production, consumption, and waste generation, we help decision-makers design circular strategies that reduce losses and increase material efficiency. Our models are based on large-scale recycling experiments. They support evidence-based policymaking, infrastructure planning, and resource management. This systemic approach provides the foundation for a more sustainable metabolism of urban and rural areas in which waste becomes a resource. |

| Abstract | We develop and enhance technologies that enable true circularity in material use. Our research focuses on mechanical, chemical, and hybrid recycling processes that recover valuable components from demolition and municipal solid waste streams. By combining engineering know-how with sustainability assessment, we design processes that minimize energy use and emissions while maintaining material quality. The goal is to integrate these technologies into viable circular economy systems that keep resources in use for as long as possible. Through partnerships with industry and public stakeholders, we translate scientific findings into scalable recycling solutions — paving the way toward a resource-efficient low-carbon future. |
