San Francisco waste employees will be collecting discarded Christmas trees and turning them into wood chips for use at a waste-to-energy facility.
New Yorkers set a new record by bringing more than 23,000 Christmas trees for recycling at "Mulchfest" events citywide.
The Department of Parks & Recreation says Monday that just over 23,600 trees were brought by residents to more than 80 parks over the weekend. They say that's a 38 percent increase over the more than 17,000 trees recycled at last year's Mulchfest.
The trees are chipped and used as mulch in city parks, ballfields and community gardens.
The Department of Sanitation is picking up trees left at the curb for recycling until Friday, Jan. 15. Last year, the city recycled more than 160,000 trees, including those collected at Mulchfest events.
