Secondary crushing, screening and processing (cone crushing) When utilizing this data set for Life Cycle Assessment, attention should be given to the following methodological advisories: Ensure that the transportation of raw materials and the end products are included in the system boundaries if they are significant. Include recycling and recovery rates for the construction aggregates if applicable. Model the use phase accurately, taking into account the specific end-uses of different crushed stone sizes. Consider the energy consumption and emission outputs of the cone crushing and sand making processes. Lastly, account for any upstream or downstream processes associated with this industrial process that may impact the overall environmental footprint.
