New York City paid Mckinsey $4m to conduct a feasibility study on whether trash bins are better than leaving garbage on the street.
The deck is 95-slides long and titled “The Future of Trash”.
Some highlights:
▫️The official term is “containerization”, which is the “storage of waste in sealed, rodent-proof receptacles rather than in plastic bags placed directly on the curb.”
▫️Two main types of containerization: 1) individual bins for low density locales; 2) shared containers for high-density.
▫️NYC needs to clean up 24,000,000lbs of garbage a day
▫️Containerization has only become the norm worldwide in major cities in the past 15 years.
▫️New York City first considered containerization in the 1970s but never conducted a feasibility study until now (Mckinsey’s sales team has been dropping the ball)
▫️Key considerations for container viability:
• POPULATION DENSITY: NYC has 30k residents per square mile (more dense than comparable big cities)
• BUILT ENVIRONMENT: Few places to “hide” containers due to history of infrastructure development.
• WEATHER: Snow creates challenges for “mechanized collection” in the winter.
• CURB SPACE: Mostly taken up by bus stops, bike lanes, outdoor dining and fire hydrants.
• COLLECTION FREQUENCY: NYC needs to double frequency of pick-up for estimated speed of trash that bins would accumulate.
• FLEET: A new garbage truck will needs to be designed to collect rolling bins at scale.
▫️ The proposed solution (literally garbage bins and shared containers) covers 89% of NYC streets and 77% of residential tonnage.
▫️The three case studies — because you gotta have solid case studies — are Amsterdam, Paris and Barcelona.
▫️There is a slide called “Why containerization matters” and three reasons are “rats”, “pedestrian obstruction” and “dirty streets” (the 21-year intern that did this slide billed at prob $10k an hour is my hero).
The study is actually pretty interesting.
I have no idea if $4m is a rip-off to learn that “yeah, we should put garbage in bins so rats don’t eat it” but I would have happily done it for 10-20% of that budget (and come to a similar conclusion).
