Initial assessment — Estimation of GHG emissions at system-wide level

The reset button does several things:

1. Sets the tier B values to 0, except the tier A ones.
2. Sets "Are you producing biogas?" to "No".
3. Sets "Are you valorizing biogas?" to "No".
4. Sets "Select main treatment tye" to "None".
5. Sets "Select sludge disposal method" to "None".

All the inputs that have estimations are set to zero:

• Biogas produced = 0
• Percentage of methane in biogas = 0
• Biogas valorised = 0
• Biogas flared = 0
• Influent BOD load = 0
• Effluent BOD load = 0
• BOD removed as sludge = 0
• CH4 emission factor = 0
• Sludge produced in WWTPs = 0
• Dry weight in sludge produced = 0
• Sludge composted = 0
• Sludge incinerated = 0
• Sludge sent to land application = 0
• Sludge sent to landfilling = 0
• Sludge stockpiled = 0
• Fluidized Bed Reactor Temperature = 0

Then, the estimations can be recalculated clicking again the options for biogas production, treatment type and sludge disposal method.
