Holiday Collection 2018-2019
opalaRemember, no trash or recycling collection on December 25, 2018 and January 1, 2019. For more information on holiday collection and information see our Holiday Trash Tips Page.

As you approach Christmas consider reusable or live potted trees which won't require disposal or recycling. Artificial trees are another good option. The New York Times reported that, in 2003, 70 percent of the Christmas trees in American households were fake. If you go with a cut tree, please recycle. Island residents can choose curbside collection (more on Holiday Collection) or drop-off at Convenience Centers or Transfer Stations. Condos and commercial buildings can arrange to haul trees directly to composting facilities - there will be no charge for Christmas trees, courtesy of the City. Please be aware that the State has discontinued the special treecycling sites at parks and other locations around the island. Do not bring your trees to these sites.
