Biodiesel　is　a　renewable　and　environmentally　beneficial　energy　which　has　a　variety　of　raw　materials.　Waste　cooking　oil　(WCO)　as　one　of　the　feedstocks　has　advantages　not　only　in　the　environmental　aspect,　but　also　in　the　economy.　With　the　increasing　attention　on　the　use　of　WCO　for　biodiesel　production,　some　drawbacks　are　encountered　as　well.　This　paper　aims　at　using　SWOT　analysis　to　find　out　the　strengths,　weaknesses,　opportunities　and　threats　of　WCO　as　a　raw　material　for　biodiesel　production.　Results　show　strengths　including　guaranteed　food　security,　energy　security,　and　positive　impact　on　the　environment　as　well　as　offering　direct　and　indirect　jobs.　The　weaknesses　include　complex　production　process,　low　recovery　rate　of　WCO　and　high　standards　demand　for　WCO　as　a　raw　material.　Biodiesel　produced　from　WCO　is　capable　of　dealing　with　the　increasing　concern　of　environmental　protection　and　the　demand　for　renewable　energy.　Moreover,　governments　have　been　making　laws　and　regulations　to　support　its　development.　These　mentioned　above　are　all　the　opportunities　with　the　use　of　biodiesel.　Lack　of　efficient　economic　incentive,　other　energy　sources　competitors　and　a　small　market　for　biodiesel　can　be　threats　for　its　development.　©　Published　under　licence　by　IOP　Publishing　Ltd.
