From the City of Raleigh website :

Looking for a way to get rid of all that cooking oil and grease left over from your Thanksgiving dinner? You can take advantage of the City of Raleigh’s curbside grease collection program.
For the third consecutive year, the City of Raleigh is collecting used grease and oils from residences and places of worship in the Capital City during the holiday season. To arrange for curbside collection of these materials, call the City’s Solid Waste Services Department at 996-6890 . The department is closed on Thursday for the Thanksgiving holiday but is open the rest of this week including Friday.

The City of Raleigh is collecting the unwanted grease or cooking oil at no charge. The collected grease is converted to biofuels by Triangle Biofuels Industries.

The goal of the curbside grease collection program is to protect the environment by keeping cooking grease out of the City’s sewer system and preventing sewer overflows. In order to be collected, the oil must be placed in a sealable and preferably clear plastic container marked as “used cooking oil.” The curbside grease collection program ends on Jan. 13.
