### Cost Analysis  
A cost analysis derived from product manufacturing was conducted and the profitability was studied. After that, an analysis of the CO\({}_{2}\) emissions derived from the production of the material was conducted, establishing the environmental impact during the production process.  
Regarding how much money these new configurations can save compared to commercial precast materials, the base prices of each material were established and are presented in Figure 5. This study has considered the commercial prices in the calculation of production costs, since it is not possible to access the prices that different producers have with various companies. Even using commercial prices, the potential savings are significant and may therefore be increased when considering supplier prices.  
Considering the amount of material needed for the sample elaboration, a potential 49% could be saved just by adding RGW to this material. Moreover, the perlite addition would lead to a potential 57% in savings. On the other hand, in addition to the costs derived from

the material, we must estimate both the fixed and variable indirect costs derived from the manufacturing, which may be defined as follows:  
* Variable indirect costs: These may change according to the demand, and they include the payment of electricity, bills, and salaries.
* Fixed indirect costs: These are costs such as utilities, which may include security services, maintenance, cleaning, and insurance.  
All these costs may vary according to the facilities and means of the company manufacturing the product, considering that the resources may change depending on the company.
