WeCare - DSNY - Staten Island Compost Facility

Proving Cost Effectiveness of a Newly Upgraded Composting System

The Challenge

Department of Sanitation New York Explores Upgrading Composting Program


The Staten Island Compost Facility processed yard waste for the Department of Sanitation New York (DSNY.)  It has been operated under contract by WeCare Organics (now Danali Water Solutions LLC.) As part of NYC’s food waste composting program the facility is being upgraded from an open windrow turning operation to a 16-heap SG Bunker™ System with GORE® Covers to process food waste in a more environmentally responsible manner.

The SG Solution

Meeting Requirements While Producing High Quality Compost


During 2014-2015, DSNY and its consultant performed a composting technology evaluation to determine the best technology to use for the facility retrofit at the existing Staten Island Compost Facility located at the Fresh Kills Landfill on Staten Island.

Of significant importance to the Staten Island Compost project team was the GORE® Cover capability to comply with the state and local regulatory requirements for:

  1. Meeting strict air quality standards for odors and VOC emission reduction
  2. Complete separation of process water (leachate) from storm water
  3. Production of high quality finished compost

Sustainable Generation’s SG Bunker™ System with GORE® Covers was chosen for the project.  Since that time SG has been working with GHD Engineers and WeCare/Danali in the design of the system.


Results Delivered

A Sustainable Solution with True Scale


Because the site location is on a closed landfill, there has been special consideration given to the geotechnical aspect of the project requiring multiple phases of construction.

Construction for the project is underway for Phase 1 which is focused on the site work portion of the project.

Phase 2 of the project will be the construction of the 16-windrow SG Bunker™ System with GORE® Covers. Construction is scheduled for 2018.
