H2 – Circular economy in the construction and ceramic industry
Abstract
This session explores the growing fields of structural element re-use as well as the use of sustainable raw materials within the context of sustainable construction. Challenges and opportunities associated with re-using elements from existing buildings, focusing on best practices in design, quality assurance, and material performance will be discussed. Attendees will gain insight into how re-use can reduce environmental impact, improve cost-efficiency, and drive innovation in structural engineering. On the other hand, key aspects related to the benefits of using secondary raw materials in the construction sector such as reduction of environmental impact, energy efficiency, waste minimization, energy consumption reduction or economic sustainability, will also be addressed. The session will highlight real-world applications and future trends, appealing to engineers, architects, and sustainability professionals
Scope
The session aims to provide an interdisciplinary overview of structural element re-use and secondary raw materials use in building design and construction. Key topics will include the technical and regulatory challenges involved in re-using elements and secondary raw materials, how to integrate these materials into new designs, and strategies for ensuring safety and quality. Benefits of extending the life cycle of materials, while also discussing the broader environmental and economic impacts will be explored too. The session will serve as a platform for collaboration between researchers, industry experts, and practitioners.
Description
Structural element re-use and secondary raw materials use are emerging practices in the construction industry, offering both environmental and economic benefits. This session will delve into the technical, regulatory, and design considerations that arise when incorporating previously used elements into new structures. Discussion will be focused, on one hand, on how to effectively integrate re-used materials into the design process, ensuring that they meet modern performance standards and align with building codes, and, on the other hand, on how secondary raw materials can be introduced as components of construction materials meeting performance standards and assuring quality and safety levels.
In this respect, a major focus will be on quality assurance processes, which are critical for ensuring the structural integrity and durability of construction materials and re-used elements. The session will address methods for testing and certifying materials, as well as guidelines for inspecting their condition.
In addition to technical aspects, the broader context of sustainability, examining how re-using structural elements and using secondary raw materials contributes to reducing construction waste, conserving resources, and minimizing carbon footprints, will be explored. The session will feature case studies that demonstrate the successful implementation of re-used materials in both small and large-scale projects, highlighting the potential for innovation in this field.
Targeted topics
- Recycling of ceramic waste in the construction sector
- Construction and demolition waste
- Eco-Friendly manufacturing processes

H3 – Carbon-Capture technologies, polymeric and bio-based materials in circular economyion control
Scope
The scope of this symposium is to present updates on the use of waste streams of our society (CO2, plastic, biomass) as a renewable source of raw materials. Reusing polymers or biopolymers, retrieving building blocks from CO2 or biomass and recycling are all new solutions that our society needs to implement in order to reduce its environmental impact. This call for abstracts aims at collecting the most recent updates on the enabling technologies that are needed for this transition.
Description
We are currently facing the effects of climate change and inappropriate use of natural resources through increasing global warming, flooding and environmental pollution (air and water). CO2 is strongly contributing to this general trend and reducing the carbon emissions and footprint is the challenging issue worldwide. Besides, waste management, bio-sourcing, and green processes will promote the circularity of production and consumption (by using waste as a renewable source of raw materials) while reaching the net zero CO2 emissions. The present symposium wishes to highlight approaches which can be used to limit carbon emissions or contribute to carbon sequestration. Indeed, innovations and recent works on recycling and green productions of polymers (for example plastics), valorization of waste into composite of building blocks and composites (eco-materials) will be encouraged. Another issue is to promote close international collaboration between scientists, industry, and relevant authorities and agencies.

Scope
This symposium focuses on fundamental research in sustainable metallurgy, particularly in the production and processing of ferrous and non-ferrous metals, to drive a paradigm shift in the metal industry and reduce greenhouse gas emissions.
Description
Metals are the backbone of modern society, essential for various applications, such as infrastructure, construction, automotive, and aerospace, etc. Additionally, they are necessary for the emerging global transition toward green and clean energy. The metal industry, despite its crucial role, faces significant sustainability challenges, particularly due to the energy- and CO2-intensive production processes, often connected to the usage of fossil energy carriers. To achieve the transition toward sustainable metal industry, metals must be produced in cleaner ways and circular economy principles need to be implemented by exploiting different R-strategies (recycling, re-use, re-manufacturing, etc.). To address this paradigm shift, it is imperative to urgently investigate and understand the fundamental phenomena of sustainable metallurgy processes. For this matter, this symposium addresses various aspects along the metal production and processing chain.
Targeted topics
- Sustainable metallurgy approaches of ferrous and nonferrous metals using renewable energy resources, e.g., renewable hydrogen, electricity, and biomass, etc.
- Novel alloy design strategies, which enable the circularity of metals through recycling, re-use, and re-manufacturing (R-strategies)
- Fundamental understanding of physical, chemical, and mechanical phenomena in sustainable metallurgical processes
- Theory-based computational prediction and optimization of sustainable metallurgical processes
Applications of life cycle assessment as a tool for sustainable metal design, production, and processing
