This study tested LFGC as a denitrification carbon source in sequencing batch reactors (SBRs) co\u2010treating municipal sewage and landfill leachate. Four lab\u2010scale SBRs operated for 170\u2009days with 98.5% sewage and 1.5% landfill leachate, supplemented with methanol, glycerin, sodium acetate, or LFGC. All reactors performed stably, achieving total nitrogen removal efficiencies of 93.1%\u201393.8% and effluent nitrate below 1\u2009mg\u2009N\/L. The LFGC reactor reached nitrate removal up to 99.2%, with effluent NO\n                    <jats:sub>3<\/jats:sub>\n                    \u2013N as low as 0.31\u2009mg\u2009N\/L.

EEM\u2013PARAFAC and FTICR\u2013MS analyses showed similar dissolved organic matter characteristics in all effluents, indicating that LFGC did not produce distinct fluorescent or molecular DOM signatures compared with conventional carbon sources. Overall, LFGC performed comparably to conventional liquid carbon sources while beneficially reusing a landfill byproduct.\n                  <\/jats:p>","DOI":"10.1002\/wer.70454","type":"journal-article","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T09:11:05Z","timestamp":1782205865000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Valorizing Landfill Gas Condensate as an External Carbon Source for Denitrification in Sewage\u2013Landfill Leachate Co\u2010Treatment"],"prefix":"10.1002","volume":"98","author":[{"given":"Md.
