Dear Ajuyah,

Thank you for your concept about the calculation of faecal output per person. We are in agreement with your estimation of faecal sludge in China as well as intake and its digestibility; age, sex, ethnicity and other parameter can permit to calculate fecal output for any community.

However, we would like to stress that the latrine-cum-biodigester was constructed outside the refugee camp i.e. in area affected by the activity of refugees for the benefit of local community.
