ReBuilt - Circular and digital renewal of central Europe construction and building sector


Duration: 1. 4. 2023 - 1. 6. 2026
Evidence number:CE0100390
Project leader: Prof.Dr.Ing. Palou Martin-Tchingnabé
Annotation:The construction industry is one of the most natural resource-consumption sectors (more than 50% of all extracted materials, 50% of water, and 1/3 of energy are used in construction, which also produces more than 1/3 of all wastes and 1/3 GHG), therefore boosting the circular economy (CE) in this sector produces a significant impact on central European society's well-being and increases its resource efficiency. The current situation of innovation ecosystems for circular and digital construction varies significantly from region to region. While some regions already have good practices of using recycled materials and established administrative procedures (e.g., End-of-Waste criteria), others are still making initial steps towards circular and digital construction (e.g., focusing mainly on backfilling of Construction and Demolition Waste). Nevertheless, the common gaps in all regions are: (1) General reluctance towards Secondary Raw Material (SRM)-based products; (2) Lack of operating SRM-based construction market; (3) Lack of appropriate data about the quality of SRM-based products and their traceability (waste to product flows); (4) Lack of administrative/legal routes for reuse of products; (5) Lack of good practices of circular economy business models; (6) Lack of transnational education program for T-shaped experts. The overall objective of the ReBuilt project is to increase awareness and attractiveness of circular and digital construction through the creation of an education program, upgrade and piloting of new solutions (technical and digital), upgrade demand-side measures, including green labeling, EoW, Green Public Procurement (GPP) and through the creation of first Central European Circular and Digital Construction Strategy, which will be deployed through a network of Regional Circular and Digital Construction Hubs. The project outputs and results will further uptake construction in central Europe, taking into consideration regional and urban/rural specifics.

INHAAR - International network for harmonization of atmospheric aerosol retrievals from ground based photometers

Charakterizácia atmosférického aerosólu z pozemnej rádiometrie

Duration: 1. 10. 2022 - 31. 10. 2026
Evidence number:CA21119
Program: COST
Project leader: Mgr. Kocifaj Miroslav DrSc.
Annotation: Aerosols are particles floating in the Earth’s atmosphere linked with the largest uncertainty on estimates and interpretations of the Earth’s changing energy budget. Measurement principles differ depending on the desired derived aerosol optical parameter and on the measurement platform (surface or space). The common aerosol columnar properties’ retrieval techniques, consists of direct measurement of a bright source of radiation (sun, star, moon, sky) with a multi-wavelength photometers. Several global photometric aerosol networks exist. However, there are several instrumental, algorithm and hardware based differences on their related aerosol products and a global standardization is needed. In addition, in order to improve and optimize sun- and moon- photometric aerosol measurements, a network of aerosol scientists and operators, aerosol measurement users and software, hardware developers is needed. The objective of “ΗΑRΜΟΝΙΑ” Action is to establish a network involving institutions, instrument developers, scientific and commercial end users, in order to improve and homogenize aerosol retrievals using mainly solar and sky but also lunar and star photometers from different networks. It aims bridging user needs and the science and technology expertise residing in academia and industry, through: - Increasing the interactions and knowledge exchanges between several atmospheric aerosol network measurement scientists and users - Standardizing and improving of existing aerosol products and tools, towards a “harmony” in the aerosol photometry - Stimulating the communication between operational agencies and academia, with the aim to increase the applicability of aerosol products. - Encouraging and organizing the dialogue between researchers and instrument manufacturers, towards innovation actions on current and future photometric-aerosol instrumentation.

H2GEO - New technology for the production of hydrogen and geopolymer composites from coal mining wasteuction from post-mining waste

Nová technológia výroby vodíkových a geopolymérnych kompozitov z odpadu po ťažbe uhlia

Duration: 1. 7. 2023 - 30. 6. 2026
Evidence number:101112386
Program: 5RP
Project leader: Prof.Dr.Ing. Palou Martin-Tchingnabé
Annotation:The current situation in the fuel market, mainly related to the war in Ukraine, may cause interruptions in the supply of fuels and other raw materials, including building materials. The development of a comprehensive technology for the management of mine waste dumps is planned within the project. The main idea of the project is to use the separated mineral fractions and fly ash to produce geopolymer composites. It is planned to use CO2 as a process carrier in the production of composites. Another important aspect of the project is determining the possibility of obtaining Hydrogen from gasifying energy fractions. High-quality raw materials for the production of geopolymers and hydrogen will be ensured by using an innovative mobile separator to process mine waste. The project will enable the creation of environmentally friendly and economically justified installations using material from a post-mining waste landfill. Achieving the final goal will be possible thanks to the implementation of the partial goals set in the project, including the development of technologies dedicated to the production of geopolymers and hydrogen.

BSS - The birth of solar systems (PLANETS)

Prachové častice v slnečnej sústave

Duration: 1. 9. 2023 - 30. 9. 2027
Evidence number:CA22133
Program: 5RP
Project leader: Mgr. Kocifaj Miroslav DrSc.
Annotation:Solar systems emerge from the dust, gas, and ice present in discs encircling newly-born stars. State-of-the-art images from current telescopes have revealed complex substructure (rings and gaps) in dust and gas that may be caused by forming planets. However, these observations have raised many questions regarding when and how planets form; for example, we see rings in discs too young to birth planets, and we measure disc masses too low to form a Solar System analogue. Further, the demographics provided by observations of extra-solar planetary systems have revealed huge diversity and hint that our Solar System may be unique. It is clear that our picture of the birth of Solar Systems remains incomplete despite these great advances in observations. This Action will create a multi-disciplinary network covering three cornerstones: experiments, models, and observations. Experimental data is needed to accurately prescribe physics in models of disc evolution and planet formation, and to correctly interpret observations of dust and gas emission. Models are a “virtual laboratory” within which the impact of physics can be explored, and from which observational diagnostics can be created. Finally, observations provide us with the benchmarks needed to confirm or refute our picture of Solar System birth. To build a holistic picture of how Solar Systems form can only be achieved with an interdisciplinary and pan-European network. This Action will provide the structure and funding needed to develop the research framework, provide training to the next generation, and to disseminate the findings to key stakeholders.

LIGHT-POLLUTION- - Comprehensive model of light pollution propagation into the ambient environment

Komplexný model šírenia svetelného znečistenia do okolitého prostredia

Duration: 1. 7. 2023 - 30. 6. 2027
Evidence number:APVV-22-0020
Program: APVV
Project leader: Mgr. Kocifaj Miroslav DrSc.
Annotation:The proliferation of outdoor artificial light at night is a global challenge that relates strongly to cities. The brightening of the night sky due to the phenomenon of skyglow touches on many social concerns from urban ecology to human health, energy security, and sustainability and climate change. Knowledge of the hemispherical night sky brightness (NSB) produced by ongoing expansion of outdoor lighting systems is a necessary step for characterizing the nighttime environment and monitoring the evolution of night sky quality. We intend to develop a comprehensive NSB model applicable for any site worldwide, while respecting the atmospheric conditions prevailing at the respective locality. By achieving an excellent match between theory and experiment, the model will (1) accurately assess the environmental impact of new outdoor lighting installations; (2) investigate the relationship between light pollution and other forms of environmental pollution; (3) elucidate how the nature of anthropogenic particles in the atmosphere relates to the formation of skyglow over cities; (4) predict how much light at night reaches the ground in and near cities; and (5) determine the value of specific outdoor lighting modernization efforts in reducing light pollution. Our strategy to develop a comprehensive model is to derive governing equations in analytic forms in order to provide a deep physical insight to the problem solved, interpret of the role of each parameter, discover dependencies otherwise hidden or unknown, and construct theoretically well-founded approximations. We will solve the vector radiative transfer equation in the Earth’s atmosphere, while determining Stokes parameters for arbitrary cloud coverage or light emissions from artificial sources. Through a combination of radiative transfer modeling and experimental validation, we deliver novel NSB mitigation strategies.

MEMOLIPO - Measuring and Modelling Light Pollution

Meranie and modelovanie svetelného znečistenia

Duration: 1. 9. 2022 - 31. 8. 2025
Evidence number:1384/03/01
Program: SASPRO
Project leader: Dr. Wallner Stefan BSc MSc
Annotation:This project aims to investigate various approaches in measuring and modelling of the global phenomenon of light pollution, artificial light at night which is misdirected, overilluminated and/or makes use of harmful light. The ever-worsening phenomenon impairs not only the visibility of objects on the night sky, furthermore it is a major threat for all organisms worldwide, including human health suffering from impacts. Research goals of MEMOLIPO include a greater understanding of atmospheric impacts on the night sky brightness and how currently used measurement devices can show new approaches in their application. Firstly, light monitoring network data underly strong seasonal variations which can potentially falsify long-term analyses of light pollution development. Such must be included in order to rightly give statements about increases or decreases in night sky brightness values. Another research issue is the impact caused by atmospheric elements like the aerosol optical depth. Latter will be investigated by meteorological ceilometer backscatter data, providing data for this issue in an unprecedented accuracy. Furthermore, airborne vehicles will be tested as potential devices to characterize atmospheric layers. Moreover, it will be tested if easy retrievable ground-based measurements can approximate the city emission function, a very important input for theoretical modelling. And finally, allsky measurements will show, how far light domes from light emitting cities are visible and could influence night skies above natural protected areas. Results from this project lead to important insights in the understanding of skyglow phenomena and serve as inputs for modelling approaches in the future. Outcomes shall also be used for research disciplines of other fields, since it creates new fundaments for nature related studies in, e.g., ecology, biology and environmental physics, or technical studies like lighting management, sustainability and energy saving purposes.

Program: APVV
Project leader: Prof.Dr.Ing. Palou Martin-Tchingnabé
Annotation:The study of chemistry, phase evolution, and phase equilibrium during the hydration of multicomponent cementitious materials is a key challenge in the development of construction materials with high performance. Therefore, 1. the present project deals with the complex study of the effect of normal and hydrothermal curing conditions on hydration reaction of multicomponent cementitious binders for the objective of optimizing the composition of cementitious composites for high-temperature hydrothermal wells; 2. the project will develop heavyweight concrete based on the optimized composition of multicomponent cementitious binders and high-density aggregates. The concrete design will take into consideration the radioactive isotopes, in order to minimize the activation effect of gamma and neutron radiations, when it comes to being used as biological shielding in power nuclear plants; 3. the purpose of the present project is the development of advanced concrete materials, unique in its kind; Fiber-Reinforced Heavyweight Self-Compacting Mortars with special protection properties against ballistic missiles. The common denominator of these objectives is the chemistry of hydration reaction, including kinetics and mechanisms, phase evolution, and equilibrium of composites comprising Ordinary Portland (OPC) cement and Supplementary Cementitious Materials (SCMs). Different curing regimes (ordinary, hydrothermal), complex chemical analysis including radioactive isotopes of each ingredient, the particle size distribution of binders and aggregates are some of the main factors which are the driving forces for the implementation of the submitted project.
