Presentation Title: Decentralized, Urban Composting

co-authors: Leah Retherford, Big ReUse, & Marguerite Manela of New York City DSNY

Session: Planning for Organics Recycling in Urban and Regional Settings

Time: Wednesday, January 30, 8:45 AM – 10:15 AM

Presentation Summary: The NYC Compost Project Hosted by Big Reuse is a program funded by the New York City Department of Sanitation, which features a food scrap compost facility, located under the Queensboro Bridge. The compost facility uses the GORE® Cover System technology, which isa covered aerated static pile (ASP) system. SCS Engineers (SCS) prepared a new facility layout, which will increase the processing capacity of the site to 1000 tons of food scraps annually.

The facility layout occupies a ½-acre parcel and includes the following:
•Two (2) GORE® Cover Systems, approximately 20 feet by 50 feet (Phase 1).
•Windrow areas for Phase 2 and Phase 3 (uncovered).
•Stockpile areas for feedstock, and finished compost.
•Mobile equipment, including a skid-steer loader, mixer, screen and food scrap containers.
•Storage container.
•Working surfaces.
•Stormwater management features.
•Contact water management features.

Vector nuisances and odor generation are minimized through the use of the cover system and contact water iscollected. The GORE®Coversystem utilizes forced aeration, coupled with a semi-permeable membrane cover, to achieve a fully-encapsulated composting process.

The NYC Compost Project works to rebuild NYC’s soils by providing New Yorkers with the knowledge, skills,and opportunities they need to produce and use compost locally. The compost facility is part of the NYC Compost Project, and part of a community-scale composting network in New York City. The finished compost is used in community gardens, on street trees, and in public beautification projects.

The following design and operational items will be presented:
1. Site layout.
2. Feedstock mixing.
3. Covered ASP system.
4. Open windrows.
5. Monitoring.
6. Screening.
7. Odor and contamination issues.
