Sažetak
Adaptation to climate changes determines new goals in the economy, and success depends on the use of technologies which replace fossil fuels. The most effective way to reduce greenhouse gas emissions in the cement industry is the use of alternative fuels originating from biomass. Therefore, several procedures of reviewing the need for environmental impact assessment/s were conducted in cement plants. The aim of this paper was to determine, by energy recovery, the impact of using olive pomace as an alternative fuel in the cement production process through the emission of carbon dioxide, sulfur dioxide, nitrogen oxides, dioxins, furans and heavy metals, as well as the comparison of the observed fuels’ calorific values in the production process of cement company CEMEX Croatia. In a sample of entities of 120 daily average emission measurements of carbon dioxide, sulfur dioxide, nitrogen oxides (60 days of measurement in which exclusively fossil fuel was used - 30 days in 2011 and 30 days in 2012) and occasional measurements of dioxins, furans and heavy metals, in addition to 60 days in which the amount of olive pomace used was defined as an alternative fuel (30 days in 2011 and 30 days in 2012), there was a statistically significant difference in defined clusters. Univariate analysis of variance (ANOVA) showed statistically significant differences in CO2 emissions between clusters of measurements that used olive pomace and those which did not, while emission values from other observed parameters also indicate reduced emission levels, but do not show statistical significance. All emissions results were compared with models and calculation balance emissions from the procedure of environmental impact assessment.
