We cannot underestimate the barriers
• Lack of technological alternatives
• Density (compliance)• Service provision
(public workforce; free-market private sector)
• Facility Siting
![Page 38: Waste Management in New York City](https://reader035.fdocuments.net/reader035/viewer/2022070500/56816870550346895ddee015/html5/thumbnails/38.jpg)
Organic = Carbon
Other options only involve siting because they process organics as a mass, without separate sorting
