Carbon monoxide (CO) concentration during food waste composting: profiles with 6th-degree polynomial modeling

<p>This dataset contains carbon monoxide (CO) concentration values expressed in ppm, measured in the headspace of composting bioreactors during the food waste composting process. It also includes graphical representations of these values over time, along with fitted functions describing the data and the corresponding R² coefficients.</p><p>The information is organized into four files, each representing a different aeration variant used during the composting process (10 dm³/min for 0, 0.5, 1, and 1.5 minutes, files: &#34;Aeration 0&#34;, &#34;Aeration 0.5&#34;, &#34;Aeration 1&#34;, and &#34;Aeration 1.5&#34;, respectively). Within each aeration variant, the results are further divided based on the composting temperature (45°C, 60°C, and 70°C; sheets: &#34;45C&#34;, &#34;60C&#34;, &#34;70C&#34;, respectively) and different food waste (FW) to mineral material (gravelite, G) ratios: 1:0, 1:1, and 1:2 (columns: &#39;1:0&#39;, &#39;1:1&#39;, &#39;1:2&#39; in each sheet, respectively).</p><p>First, the dataset provides the individual replicate values for each FW:G ratio (n &#61; 3 for each composting variant). Following that, the arithmetic mean of the replicates is presented. Finally, the data is visualized for each variant as a plot showing CO concentration (ppm, Y-axis) over time (days, X-axis). Each plot includes a fitted 6th-degree polynomial function, the equation of the function, and the R² coefficient.</p>
