Based on doctoral research developments, the paper presents an analysis of how the use of Artificial Intelligence technologies and Data Driven Design can be the key to activating sustainable design actions that have positive impacts on the human body and communities. First we will distinguish how technology can be beneficial, in two macro cases, whether placed within the design or in the product/service itself. This will be followed by an analysis of the types of spillovers based on spatial/temporal factors and types of implementation. Research still under development focuses on comparison of case studies and analysis of literature sources. A subsequent prototyping and testing phase is planned to test whether what is hypothesised in the current phase is tangible and to what extent the effects are controllable.

AbstractThis study investigates the performance of three ultrafiltration membranes, i.e. a submerged polyethylene (PE) hollow fibre membrane, a multibore polyethersulfone (PES) membrane and a tubular multichannel ceramic membrane in the textile mercerization wastewater treatment. Experiments were carried out on two laboratory dead end membranes and on a cross flow membrane set‐up using wastewater with and without the addition of MgCl2 as a coagulant. Investigation into energy consumption was also carried out. According to the obtained results, the submerged membrane could be used as the pretreatment of mercerization wastewater to significantly reduce the amount of suspended solids, to remove organic carbon and to decrease turbidity. The results showed that the tested membranes could be used for the treatment of wastewater from the textile mercerization process in terms of permeate quality. The cross‐flow ultrafiltration consumes far more energy than the dead‐end process.

Steel slags are the by-products of steel industries, which are formed during reduction process of iron melting. The chemical composition of it changes depending to the melting procedure. Its mineralogical composition also varies based on the cooling procedure. Two different types of steel slag were used as absorbing bed for various concentrations of Pb $^{2+}$ ions in the form of lead chloride, and the concentrations of lead ions were measured in the effluent by atomic absorption spectroscopy. When Electric Arc Furnace Slag (EAFS) which is a basic crystalline slag was used in the presence of various concentrations of Pb $^{2+}$ , ranging from 2 mg/l up to 10 mg/l, the Pb $^{2+}$ ions were leached out into the solution and its concentration increased at the beginning of reaction but decreased dramatically up to 48 hours that the reaction was continuing but with slower rate. Almost the same thing happened when granulated blast furnace slag (GBFS), which is also a basic slag but in the amorphous mineralogical form, was used as the absorbing bed. The extent of ion release was much lower compared to EAFS but the absorption of lead ions took place with the higher rates. Based on this research, if EAF slag was used as absorbing bed for reduction of lead ions in the industrial waters, it takes 24 hours to absorb 10 mg/l of lead ions, while if blast furnace slag was used, maximum amounts of lead was absorbed in the first thirty minutes of reaction.
