Figure 8
The vertical bar chart is titled “Fine particulate matter formation comparison between the two analyzed cements”. The horizontal axis at the top contains three categories: “Upgrade cement (focus)”, “Upgrade cement (difference)”, and “Base cement”. The vertical axis is labeled “kilograms P M 2.5 equivalent” and ranges from negative 0.0006 to 0.0005 with an interval of 0.0001. A legend identifies three components: “Cement” shown in blue, “Gasification” shown in orange, and “Environmental saving” shown in gray. For “Upgrade cement (focus)”, a stacked bar includes a blue segment showing cement emissions of approximately 0.00027. Above it, a small orange segment showing gasification adds roughly 0.00003. Below the zero line, a gray bar showing environmental saving extends downward to about negative 0.00047. For “Upgrade cement (difference)”, a single blue bar appears below the zero line, showing cement emissions of approximately negative 0.00018. No orange or gray segments appear for this category. For “Base cement”, a single blue bar shows cement emissions reaching approximately 0.00037, with no gasification or environmental saving segments shown.
