The formaldehyde results are consistent with three somewhat competitive influences on formaldehyde yields: i) the reduction in quantity of precursors such as sugars and cellulosic materials acting to reduce the formaldehyde emissions, ii) the reduction in sidestream ammonia yields inhibiting the energetically favourable reaction of ammonia with formaldehyde to form hexamethylenetetramine, thereby potentially boosting formaldehyde emissions, and iii) greater oxidative formation of formaldehyde as the circumference is reduced and surface area to internal volume increases
