How a Returns-Focused 3PL Raised Putaway Productivity 130% With AMRs
A Midwest returns 3PL raised putaway from 124 to 285 lines per hour with AMRs, nearing one million monthly units while cutting strain and recordable safety incidents.

Cart pushes across a million square feet
A third-party logistics operator processed retailer returns inside a million-square-foot Midwest facility where putaway meant manually pushing heavy baker's carts across roughly thirty thousand square feet to more than five hundred gaylord locations.
The work was slow, error-prone, and physically demanding. Leadership needed higher throughput without expanding headcount or accepting more strain injuries on the floor.
- Long cart pushes consumed time between productive putaway touches
- Accuracy suffered when associates rushed to clear backlogs
- Safety risk rose with repetitive heavy cart moves

Robots carried the travel

The operator paired returns-processing automation with autonomous mobile robots so associates met bots at stations instead of walking entire buildings. Robots handled the repetitive transit while people focused on sortation and putaway decisions.
Integration aimed for continuity: leadership reported no significant downtime during rollout and described the deployment as a strong fit for reverse-logistics peaks.
- Baseline lines-per-hour measurement before the first AMR shift
- Zone putaway so robots meet associates at gaylord banks
- Coordinate digital returns workflows with physical bot moves
- Track accuracy and safety weekly during ramp
More lines, less walking
Average putaway productivity rose from 124 lines per hour to 285, a documented 130 percent increase. Monthly putaway volume approached one million units while transaction accuracy improved and discrepancies shrank.
Workplace accidents fell enough that the site reported more than a year without an OSHA recordable incident. Associates faced less physical strain, which leadership tied to higher morale on the returns floor.

What this means for your returns floor
Reverse logistics is travel-heavy: the win is not a faster cart push, it is removing the push entirely. Warehouse robot rental or lease lets a 3PL prove AMR putaway on one returns lane before you scale across campuses.
Service Robot Co. stays vendor neutral, matches autonomous mobile robots to your WMS and returns software hooks, and handles finance, deployment, training, and nationwide service as one partner. You keep people on sort decisions while robots hold the miles.
