Department of Sanitation New York Explores Upgrading Composting Program
The Fresh Kills Landfill on Staten Island was open from 1948 - 2001. The Staten Island Compost Project was established in 1987 as a pilot program providing valuable insights into the feasibility and effectiveness of large-scale food waste diversion. The project expanded gradually, with more households and businesses participating in the program over the years. The finished compost produced from the diverted organic waste was used for landscaping, erosion control, and soil enrichment throughout NYC. The Fresh Kills Landfill and Compost Project were closed down in 2001, although the Compost Facility reopened in 2014 with an open windrow turning operation.
The Staten Island Compost Facility processed yard waste for the Department of Sanitation New York (DSNY), 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:
Meeting strict air quality standards for odors and VOC emission reduction
Complete separation of process water (leachate) from stormwater
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.

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 12/2022] 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 CompostingTM System ready to accept a larger amount of feedstock from the region.
[UPDATE 7/2023] Phase 3: Launch - DSNY, DENALI, and Sustainable Generation will be officially launching the new SG/GORE® System in 2023. As a part of our ongoing commitment to support our partners, SG will fully train all on-site operators and assist with remote monitoring for a period after the official start when feedstock is accepted into the new SG/GORE® System.
