 Machine emission of different methods can be a default argument, because,
 at this phase we use the average emission of different machines emission
 for each part (demolition, onsite, recycling and landfilling).
-For next phases, we can use a Machine object to find the corresponding emission.
+If we are to use data for different processes, setters will be develop for
+the machines of each process to replace the default arguments. In that sense,
+a conditional will decide to use which value. The conditional will be defined
+in the setters.
+For next phases, we can use a Machine object to find the corresponding
+emission.
