AB Odour emissions from wastewater treatment plants (WWTPs) are a growing concern due to their negative impacton both workers and surrounding communities, with compounds like H2S, NH3 and volatile organic contami-nants (VOCs) contributing to air pollution and potential health issues. Biological technologies, such as biofilters(BFs), are an environmentally sustainable and cost-effective platform for odour control in WWTPs. The use of by-products from WWTPs as packed bed material in BFs would support a circular economy within the water sector.This research evaluates the performance of iron-doped pelletised compost from WWTP sludge by-products aspacking material in BFs during the removal of H2S, NH3 and VOCs at empty bed residence time (EBRT). Theexperimental set-up consisted of three 8-L BFs filled with commercial iron-doped clay pellets (control), pelletisedsewage sludge compost and pelletised sewage sludge compost doped with Fe salts. The three BFs achieved acomplete removal of H2S and NH3 at EBRTs of 60, 45, 30 and 20 s, while VOC removal exceeded 90 % at EBRTsof 60 and 45 s. The pelletised iron-doped sewage sludge compost supported VOCs removals above 92 % at 60, 45and 30 s of EBRT. This bed material promoted the growth of genera such as Thermomonas and Thiobacillus among
