Fryer Oil Do not place fryer oil in the trash or down a drain. Fryer oil from a home can be properly recycled through the District's Household Hazardous Waste Program. Contact your city service department to learn when the next collection will be held in your community. Local restaurants and bars may be willing to take fryer oil from a home and add it to their regular fryer oil collection. Inquire at local restaurant establishments. Businesses with large quantities of restaurant grease or fryer oil to dispose should refer to the District's Business Recycling Directory for a list of companies that collect the oil for recycling.
