Plaquemines Parish plans to collect Christmas trees after the season to help rebuild wetlands in the coastal parish.
The parish garbage collection company, Solid Waste North and South, will pick them up at curbside after the holidays.
Authorities said all decorations, lights, tinsel, garland and other materials must be removed. Flocked trees cannot be recycled.
Once collected, the trees will be placed along Plaquemines Parish shorelines to help fight erosion. The parish is also collecting used cooking oil, which will be turned into bio fuel to be used in Plaquemines.
Officials said residents can bring used cooking oil to the Solid Waste North facility at 170 Sewer Plant Road in Belle Chasse or 135 Compacter Road in Port Sulphur.
