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

• 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.
• Average $50 per ton cost for commingled metal/glass/plastic and beverage cartons “MGP”.

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.

• 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.
Leaf Composting Operations
Leaves are taken to the Department’s composting sites
Food Waste Composting at Rikers Island
• Rikers Island is the nation’s largest municipal prison system.
• Self-contained island houses over 17,000 inmates and 7,000 officers.
• Generates over 20 tons of food waste per day.• In 1996, construction completed of an enclosed,
agitated-bay composting system.
Food Waste Composting at Rikers Island

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

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
