The company utilizes fly ash (at a substitution rate of 4%) to replace a portion of the raw materials in the production of cement clinker. When utilizing this LCA data, consider the substitution of fly ash in place of traditional raw materials which contributes to resource conservation and environmental benefits. Appropriate allocation methods should be applied when considering recycled content and potential avoided burdens. The system boundary of 'from cradle to gate' should be adhered to, involving raw material acquisition, transportation, clinker production process, as well as considering the impacts of the upstream power generation and avoided ash disposal.
