AB  - The thermomechanical properties of the bio-fiber composite, as material for the production of thermal insulation panels, were evaluated. The observed mixtures were composed of Miscanthus × giganteus bio-fibers, mineral binders (cement or lime), pozzolanic materials (zeolite and fly ash), and water. The favorable heat transfer behavior of composites based on Miscanthus × giganteus bio-fibers was already affirmed by literature data of similar natural bio-fiber materials, the author’s previous experimental results, and consideration of dynamic heat transfer processes in the insulated outer wall exposed to variable ambient conditions. The experimental assessment was focused on the bearing capacity (i.e. compressive and flexural strength), water absorption, and durability (i.e. resistance to freeze-thaw and carbonation), because there is scarce literature data regarding these properties, whose thorough understanding and systematization are highly important for a wider application of biomass-based thermal insulation materials. The obtained results were evaluated through the comparison to published data from similar bio-based thermal insulations, as well as from conventional thermo-insulation materials such as polystyrene and stone or glass wool.

AB  - The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that effects of competition may significantly influence the efficiency of the treatment, the Simplex Centroid experimental design was used to explore ions sorption from multi-component solutions. For the purpose of this study, the common components of construction and demolition waste, such as pathway concrete and different bricks samples, were used along with the multi-component Sr2+, Co2+, and Ni2+ ions solutions. The equations for the prediction of metal ions sorption capacities were derived. The coefficients that correspond to the linear and interaction terms were obtained using a special cubic model. Likewise, by analysis of variance, statistically significant terms of the obtained polynomial were defined. The investigation has shown that the most effective sorption was onto the pathway concrete for all three cations, while the highest sorption capacity was found for Co2+ ions. Also, it has been determined that concerning Sr2+ ion removal there was a competition with coexisting Co2+ and Ni2+ ions, reducing its sorption capacity, while sorption of Co2+ and Ni2+ occurred more independently on other cations in multi-component solutions. Based on the obtained results, the applied experimental design can be efficiently used for the description of competitive sorption process and could be a powerful tool for the prediction of cation immobilization in liquid radioactive waste treatment.

AB  - Following the guiding 3R principle of sustainable development (Reduce, Reuse and Recycle), the potential applicability concerning various components of construction and demolition waste (C and DW) was investigated for radionuclide sorption (Sr, Co, Ni). Collected samples of waste concrete, facade, bricks and asphalt were characterized in respect to mineralogical and surface composition, pH and radioactivity, while their sorption capacities were determined in batch conditions. Selectivity of potential sorbents differed in respect to Co2+ and Ni2+ ions, whereas sorption of Sr2+ was generally low. Concrete and facade have demonstrated both: the highest sorption capacities and the strongest interaction with the investigated cations, as revealed by sequential extraction analysis of loaded sorbents. Taking into account chemical compatibility with mixtures, commonly used for the solidification of radioactive waste, and expressed high affinity for studied cations, waste cement materials and debris are promising matrices for radionuclide immobilization.

AB  - In this study, the applicability of waste concrete as a sorbent material for the liquid radioactive waste management was considered. The sample was properly characterized in terms of mineralogical and surface composition, particles morphology, radioactivity, and of the behavior in aqueous solutions at different solid/liquid ratios and pH values. Since radioactive isotopes of Sr, Co and Ni are significant components of the liquid radioactive waste, sequestering of their ions from aqueous media was studied in single and multi-component batch sorption systems. The capacity of waste concrete decreased in the order Ni2+(0.54 mmol/g) > Co2+(0.32 mmol/g) > Sr2+(0.25 mmol/g). Concurrent sorption was analyzed using Simplex Centroid Experimental Design and the coefficients that correspond to the linear and interaction terms were obtained using a special cubic model. The presented results demonstrate the potential of waste concrete in the radioactive waste treatment and conditioning, due to its high sorption capacity and compatibility with the solidification matrices.

AB  - The possible utilization of waste ceramic (CT) and roof tiles (RT), as sorbents for liquid radioactive waste (LRW) treatment, was investigated. Following the European directives on waste and politics of saving natural raw materials, it is reasonable and desirable to explore potential applicability of such construction wastes. These materials are lowcost and locally available in high quantities, yet, their sorption characteristics were not evaluated to this point. In the present study, detailed physicochemical characterization of waste CT and RT included determination of mineral composition, surface functional groups, radioactivity, as well as the stability in aqueous media. The batch sorption study of Sr2+, Co2+ and Ni2+ ions from single- and multi-component solutions was performed, as their radioactive isotopes are common constituents in LRW. Sorption equilibrium was best described by Freundlich isotherm model, regardless of the sorbent and the sorbate type. Sorption capacities of CT, defined in single element solutions, increased in the order 0.035 mmol Sr/g LT 0.12 mmol Ni/g LT 0.17 mmol Co/g, while the affinity of RT was generally lower (0.030 mmol Sr/g LT 0.065 mmol Co/g LT 0.10 mmolNi/g). The study of competitive cation sorption was performed following a simplex centroid experimental design matrix. The equations for the prediction of metal sorption capacities from multi-component solution were derived. Utilization of CT and RT might be an efficient way for waste water purification, with simultaneous reduction in construction waste amount on municipal landfills.

AB  - Precise understanding of heat transfer processes inside the latent thermal energy storage exposed to different initial and boundary conditions is crucial for development of optimized design and operating features of similar devices. The paper presents 3D numerical study of phase change material heat storage in the shape of vertical cylinder reservoir with axially placed heat source/sink equipped with variable number of conductance enhancing longitudinal rectangular fins. As the principally important observed is the case of vertically variable heat flux supplied to the phase change material during the melting process. The numerical modeling is based on the physical model of the process and is being carried out by Fluent software that uses finite volume method for solving continuity, momentum and energy equations. The coupling between pressure and velocity is based on the Semi- Implicit Pressure- Linked Equation (SIMPLE) algorithm. The results of numerical simulations are verified through the comparison with the own experimental results. Exemplary results for characteristic heat storage geometries and boundary conditions are presented and analyzed in the paper.

The thermo-physical features of the storage material are determined in separate experiments and implemented to FLUENT software over user defined function. Advanced thermal storage geometry comprehension and optimization required introduction of a parameter suitable for the analysis of heat transfer enhancement, so the ratio of heat transfer surfaces as a factor was proposed and applied. It is revealed that increase of the ratio of heat transfer surfaces leads to the decrease of melting time and vice versa. Numerical analysis, employing the 3-D model built in Ansys software, observed storage reservoir geometries with variable number of longitudinal fins. The adjusted set of boundary conditions was carried out and both written in C language and implemented over user defined function in order to define variable heat flux along the height of the heater. The comparison of acquired numerical and experimental results showed a strong correlation. Experimental validation of numerical results was done on the real thermal energy storage apparatus.
