Key Takeaways

  • New York City handles 24 million pounds of residential waste daily, moving it off curbs through the first large-scale containerization effort in North America.
  • Instead of relying on weight, DSNY ran a physical volumetric analysis across 70,000 blocks, factoring in street geometry and tree canopies to calculate exact bin requirements.
  • The city rejected European-style shared open dumpsters because unassigned containers invite nearby commercial businesses to dump private waste into free public bins.
  • Custom automated side-loader trucks pick up sealed Empire Bins directly from curbside spaces, avoiding manual bag tossing entirely.
  • Operations run on the DSNY 3-Tier Residential Containerization Model to separate properties by unit count.

The DSNY 3-Tier Residential Containerization Model

Tier 1: Low-Density Buildings (1 to 9 Residential Units)

Mandated to use individual wheeled trash bins (official NYC bins) placed at the curb by building waste managers, serviced manually or via truck rear-tippers rather than piled loose on sidewalks.

Tier 2: Mid-Sized Buildings (10 to 30 Residential Units)

Given an active choice between multiple wheeled individual bins or dedicated on-street Empire Bins, accommodating high variance in tenant density (e.g., 11 single studios versus 29 multi-bedroom apartments).

Tier 3: High-Density Buildings (31+ Residential Units)

Assigned stationary on-street sealed containers ('Empire Bins') dedicated exclusively to the building and serviced by automated side-loader (ASL) trucks.

When This Works (and When It Doesn't)

This framework functions across dense residential housing stock because it closes off free-rider abuse. Shared open dumpsters in European cities look elegant until private storefronts fill them up at midnight. Joshua Goodman noted that New York's operational leap relies on matching container volume directly to specific building footprints: “We planned for basically one extra day above their collection. And we went out and measured piles of trash.” (play from 25:49) When properties have clear boundaries, dedicated bins keep the public stream clean.

It struggles when street real estate faces severe geometric limits. A block with tight curb extensions, mature root systems, outdoor dining, or heavy commercial loading zones leaves no clean parking footprint for automated side-loaders. In those pockets, automated trucks cannot access containers at curb line without blocking traffic or tearing tree canopies, forcing operators back into labor-heavy manual bag collection.

What to Do With This

Apply Goodman's volume-over-weight segmentation if you run a shared infrastructure product, like a shared cloud cluster or a physical logistics route serving different account sizes.

First, audit customer consumption by physical capacity rather than nominal contract tiers. Run a 14-day sample to find who uses outsized burst capacity during peak cycles.

Second, segment users into three discrete operational tiers. Give accounts with 1 to 9 seats standardized self-service tools with strict rate caps. Give mid-tier accounts with 10 to 30 seats an active choice: they can run parallel basic queues or pay for a dedicated high-throughput instance, depending on whether their traffic is 10 lightweight workers or 25 compute-heavy workloads.

Third, ring-fence enterprise accounts with 31 or more seats onto isolated, automated resources. Never let shared public instances sit open for anyone to drop workloads into, or your small users will free-ride on hardware allocated for your high-paying enterprise contracts.
