New York, NY – Denali Water - WeCare - DSNY - Staten Island Compost Facility

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 Denali Water Solutions LLC (formerly WeCare Organics). 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 stormwater

  3. Production of high-quality finished compost


Sustainable Generation’s SG Bunker® System with GORE® Covers was chosen for the project.  Since then, SG has worked with GHD Engineers and WeCare/Denali on the system's design.

RESULTS DELIVERED

A Sustainable Solution with True Scale


Phase 1: COMPLETE - focused on the site work portion of the project. Since the site location is on a closed landfill, there were special considerations given to the geotechnical aspect of the project requiring multiple phases of construction.


[UPDATE] Phase 2: Construction Complete! The originally anticipated completion was set for Q1 2023, but the construction of the 16 SG BUNKER® System with GORE® Covers was done efficiently and was completed weeks earlier than originally anticipated. DSNY now has a fully operational SG Advanced Composting System ready to accept a larger amount of feedstock from the region.
