The problem of acid gas exhaust emissions treatment has not been fully resolved at present. Dry adsorption of acid gases with alkaline sorbents is currently being investigated, to improve solid sorbents. In this study, 5 types of hydrated lime were characterised and tested. The sorption capacities were measured by means of a system consisting of a feed line (HCl/N2), a thermostatic reactor and a water absorber. The physical characteristics of sorbent samples were also compared. Analyses conducted with scanning electronic microscopy revealed that sample C1 showed uniform particle distribution. Samples C2 and C3 showed the co-presence of fine and coarse particles. Sample C4 showed very fine particles with agglomeration phenomena. In sample C5, fibrous elements were found. Energy dispersive spectrometry (EDS) analyses showed a similar composition of the samples, with the exception of the presence of Mg in some of them. After 30 min of testing, the following differences in sorption capacities with respect to C1 (3.59 mg g−1) were found: C2, −20%; C3, −13%; C4, −17%; C5, −3%. Higher sorption capacities were associated with more uniform particle size distributions. Conversely, agglomeration of fine particles may have adversely affected the performance of sorbents.

Modern knowledge work is highly intense and demanding, exposing workers to long-term psychosocial stress. In order to address the problem, stress detection technologies have been developed, enabling the continuous assessment of personal stress based on multimodal sensor data. However, stakeholders lack insights into how employees perceive different monitoring technologies and whether they are willing to share stress-indicative data in order to sustain well-being at the individual, team, and organizational levels in the knowledge work context. To fill this research gap, we developed a theoretical model for knowledge workers’ interest in sharing their stress-indicative data collected with unobtrusive sensors and examined it empirically using structural equation modeling (SEM) with a survey of 181 European knowledge workers. The results did not show statistically significant privacy concerns regarding environmental sensors such as air quality, sound level, and motion sensors. On the other hand, concerns about more privacy-sensitive methods such as tracking personal device usage patterns did not prevent user acceptance nor intent to share data. Overall, knowledge workers were highly interested in employing stress monitoring technologies to measure their stress levels and receive information about their personal well-being. The results validate the willingness to accept the unobtrusive, continuous stress detection in the context of knowledge work.

The implementation of sustainability-oriented practices in small- and medium-sized enterprises (SMEs) has been discussed frequently over the years. Recent studies on sustainability have focused mainly on links between ecological and economic sustainability. This exploratory study aims to explore institutional barriers and facilitators regarding the implementation of sustainability-oriented practices in the Indonesian batik industry and to provide policy recommendations. The Indonesian batik industry is well-known for its cultural heritage and for being part of the Indonesian identity. Batik products are mostly hand-crafted by women crafters. The study used in-depth insights from two focus groups conducted with entrepreneurs active in the batik industry, while also building on earlier empirical insights. The lack of customer knowledge and socio-cultural and regulatory factors were found to be barriers to sustainability in batik SMEs. Ecological, technological, socio-cultural, and political factors were found to facilitate achieving sustainability objectives. This study contributes to the sustainable entrepreneurship and women entrepreneurship literature by considering facilitators and barriers as they are experienced by batik entrepreneurs and by furthering the conceptualization of sustainable entrepreneurs as either “committed” or “followers”.

This paper is devoted to how a team of experts scientifically supported redesigning the curriculum of an elective study program that promotes competences for sustainable development. In contrast to other case studies of higher education for sustainable development (HESD), the paper does not present the outcome of the curricular-redesign process but focuses on its scientific support. It shows how this process was initiated and facilitated. It understands curricular redesign as a social process. The premises are, first, that supporting curricular processes means guiding the decision-making of those in charge but not making decisions in their place, and second, that the redesign of a curriculum has to consider the existing institutional situation as well as empirical and theoretical expectations. The article discusses how scientific support can help a curricular redesign draw on both experience-based knowledge and sound HESD theories and findings. Furthermore, it reflects on the role of those supporting such a process and on how they can help the actors find a realistic compromise between the existing situation and the perceived ideal. This requires competences in mining, aggregating, and reprocessing knowledge in the field of HESD, as well as in designing and supporting an interdisciplinary process.
