Using　waste　cooking　oil　for　biofuel　production　is　potentially　beneficial　to　food　safety　and　energy　supply.　However,　the　lack　of　waste　cooking　oil　as　a　feedstock　for　biofuel　production　is　one　of　the　main　reasons　mentioned　by　the　biofuel　industry　for　the　illegal　reprocessing　of　cooking　oil　for　secondary　use.　Thus,　it　is　necessary　to　acquire　information　and　knowledge　about　how　to　inspire　restaurants　to　submit　their　wasted　cooking　oil　to　formal　collectors　such　as　biofuel　manufacturers,　rather　than　to　informal　channels.　We　carry　out　random　sampling　surveys　on　restaurants　in　Beijing＇s　urban　districts　through　interne　questionnaires　and　face-to-face　investigations　to　explore　the　behaviours,　awareness,　and　willingness　of　restaurants　to　submit　their　waste　cooking　oil　for　biofuel　production.　The　results　show　that　the　total　quantity　of　waste　cooking　oil　generated　by　restaurants　is　90.14　thousand　tonnes　in　2016.　Additionally,　24%　of　restaurants　do　not　submit　waste　cooking　oil　to　formal　collectors,　and　approximately　21.63　thousand　tonnes　of　waste　cooking　oil　is　unaccounted　for.　We　find　that　mandatory　regulations　and　economic　incentives　are　the　dominant　factors　that　affect　restaurants＇　disposal　decisions.　With　a　subsidy　value　of　4　yuan　RMB/kg,　all　the　restaurants　are　willing　to　submit　waste　cooking　oil　to　formal　collectors.　Governmental　departments　should　also　consider　building　economic　incentives,　enhancing　the　mandatory　regulation,　designing　different　methods　to　manage　different　types　of　restaurants,　and　strengthening　supervision　and　education　to　ensure　the　safe　disposal　of　waste　cooking　oil　and　promote　its　use　for　biofuel　production.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
