the moment of consumption
In total: approximately 12 million tons per year – 5.5 million tons going to disposal; 6.5 million “diverted” from disposal
Different types of waste from different types of “generators” Residents and public institutions (serviced by Department of Sanitation – Including public works projects (asphalt, demolition) Commercial entities (serviced by over 200 different private carting companies) – Offices, shops, restaurants, etc. – Construction and demolition, excavation Parallel and separate systems Different waste streams, degrees of information, composition, quantity, destinations, and outcomes
Biggest Possible View * Commercial tonnages estimated based on self-reported data, preliminary for FY11 ~ 12 million tons Citywide diversion rate of 54%
Current disposal system
Long-Term Plan: Borough Equity
DSNY Curbside Recycling Collection 400,000 tons of paper recyclables collected annually. 250,000 tons of metal, glass, & plastic recyclables collected annually.
Where Does it All Go?
Contracts for Processing NYC’s Recyclables DSNY collects recyclables and delivers them to contracted processors. Different contracts for processing commingled paper and commingled metal, glass, and plastic.
Contracts for Processing NYC’s Recyclables Average $7 per ton revenue for paper. cost Average $50 per ton cost for commingled metal/glass/plastic and beverage cartons “MGP”.
NYC’s Paper Recycling Contracts The Visy plant on Staten Island receives 160,000 tons of paper per year, over 40% of the paper collected for recycling. Visy Paper Mill
NYC’s Paper Recycling Contracts Remaining 60% sold to paper processors who separate the paper into various grades.
NYC’s Metal, Glass & Plastic Contract Major U.S. scrap metal processor Long time processor of NYC metal Current processor of NYC’s MGP recyclables and selected as long term processor. Sims Metals Marketing
Sims Waterborne Network Hunts Point, Bronx Long Island City, Queens Claremont, Jersey City in New Jersey
Sims Claremont Facility in Jersey City, New Jersey Receives MGP from southern Manhattan and Staten Island Receives Bronx MGP by Barge
Waterborne Network for Recycling New materials recovery facility at the South Brooklyn Marine Terminal Proposed Marine Transfer Station in Manhattan
Composting Program 20,000 tons per year autumn leaves. 6,000 tons per year landscaper grass and yard waste. 2,500 tons per year Christmas trees. 7,000 tons per year Rikers Island food waste. 35,500 tons per year total
Fall Leaf Collection Program includes 34 of the City’s 59 Districts.

NYC Compost Project Compost outreach and education to residents and businesses. Funded by DSNY, programs are carried out by staff at the City’s four Botanical Gardens and Lower East Side Ecology Center in Manhattan
Electronics Recycling Events Sites throughout the five boroughs Accepted: – Computers – Peripherals – TV’s and other A/V – Batteries – Cell-Phones
Four-fold Increase in Participation 2004 to 2008 Electronics make up only 0.9% of NYC’s waste stream …that’s 33,939.8 tons or 67,899,600 pounds a year
Want to Really Make a Difference? Recycle More Paper
Paper: the most under-recycled material
Organic Wastes: Rotting, Gaseous and Unwanted
Compostable Under Industrial Conditions (not in backyard)
We cannot underestimate the barriers Lack of technological alternatives Density (compliance) Service provision (public workforce; free-market private sector) Facility Siting
Organic = Carbon Other options only involve siting because they process organics as a mass, without separate sorting
