Committee on Sanitation and Solid Waste Management Oversight Hearing: The City’s Infrastructure to Handle & Process Organic Waste

  • While any diversion from landfill is better than none, traditional composting is preferable to codigestion. This is because anaerobic digestion creates two byproducts: biogas and biosolids. Biogas is primarily methane, a greenhouse gas that gets burned into the atmosphere if it is not captured for reuse. I supported the pilot program at the Newtown Creek Wastewater Treatment Plant that sought to capture this methane and redistribute it into the city’s heating system; however, I have been disappointed by the years of delays in implementation and failure of the system to function reliably. Biosolids are the solid byproduct of processed sludge. According to DEP, New York City produces about 1,400 tons, or 600 tuckloads, of biosolids per day at its wastewater treatment plants, and much of it ends up in landfills. If at all avoidable, we should not be adding more inputs into this system until DEP can achieve its goals of reliably capturing methane emissions and achieving 100% beneficial use of biosolids.
  • 2. Again, we will visit this in more detail next month, but I want to reiterate that community composting facilities play a critical role in a comprehensive organics diversion system. These facilities:
    • a. Divert millions of pounds of food waste from landfills every year;
    • b. Provide free compost to the Parks Department, community organizations, street tree maintenance, school gardens, Botanical Gardens, and community gardens;
    • c. Create jobs; and
    • d. Play a critical role in educating youth and the public about the value and mechanics of composting.
  • 3. Acknowledging the benefits of community composting, last year the City Council passed the Community Organics and Empowerment (CORE) Act, requiring DSNY to establish at least 30 organic waste drop-off sites citywide, with at least three in each borough. It is disingenuous for DSNY to argue that they can meet this bill’s mandate through use of drop-off bins that send organics to Newtown Creek, given the issues with that pilot and the benefits of community composting facilities outlined above.
