“…In the context of existing literature on this subject, research not only aligns with but also extends the foundational knowledge concerning fluoride emissions in the phosphorite roasting process. One key facet of our investigation delves into the temperature-dependent relationship between firing temperature and the defluorination of phosphorite, drawing parallels with findings from previous research conducted by M. Smol et al 27) . Specifically, aim to shed light on the intricate dynamics of fluoride compound release during phosphorite roasting, particularly when mechanical activation techniques are employed.…”

The purpose was to investigate the process of formation and characteristics of fluorine compounds in the production waste upon roasting mechanically activated phosphorite, as well as the development of effective methods and technologies for their utilisation. The present study employed the analytical method, the classification method, the functional method, the statistical method, the synthesis method, structure-functional method, method of deduction. During the study, the composition of waste products from the roasting of mechanically activated phosphorite was analysed. Proper treatment of fluoride compounds is critical to preserving the environment and ensuring general well-being. These substances are toxic and can harm ecosystems and human health. Fluoride compounds generated during firing can have a negative impact on biological systems, and therefore, the effective disposal of these substances is becoming an integral part of the industrial production of phosphate rock and mineral fertilizers. The waste was found to contain significant amounts of fluoride compounds, including gaseous and solid forms. This confirms the need to develop methods and technologies for their utilisation.

“…In order to minimize this gap, some researchers limitedly conducted the sensitivity analysis by comparing some credible scenarios to observe the deviations according to scenario changes (Smol et al, 2019). Nevertheless, their attempts could not address the fundamental limitations of LCA on a case-by-case basis.…”

In response to the impending international maritime regulation, MARPOL Annex VI Reg. 14, to curb sulphur oxides (SOx) arising from shipping activities, this paper aimed to evaluate the environmental impacts of the entire life cycle of three different SOx reduction scrubber systems: (1) 'wet open-loop', (2) 'wet closed-loop', and (3) 'wet hybrid'. To achieve this goal, the paper developed 'the Parametric Trend Life Cycle Assessment (PT-LCA)' which was introduced to proceed the extensive analysis for a number of case ship studies and quantify various emissions, such as greenhouse gases (GHG), sulphur oxides (SOx), nitrogen oxides
