New York City trees that became debris during Sandy will be turned into biofuel, mulch and landfill cover.
The plans were announced Tuesday by the city and the U.S. Army Corps of Engineers.
More than 15,000 trees were downed in the storm.
Nearly 100,000 cubic yards of chipped and non-chipped tree debris has been piled at Floyd Bennett Field in Brooklyn. Officials expect the total to double as the cleanup continues.
The city also says natural decomposition causes temperatures to rise in the debris piles. To reduce the risk of combustion, some of the debris will be incinerated using a method designed to protect the environment.
