1746 aggregates. In 2021, a total of 1.6 million tonnes of aggregates were produced. Table 37 show the production data, along with resource consumption and waste generation data at the site. Figure 108 – Processing circuit of the quarrying site. 4. RESULTS AND DISCUSSION This section presents the results obtained from the two methods. Furthermore, this section presents the underlying reasons for the differences observed between the results.
