Portsmouth to Launch Automated Trash and Recycling Pilot in 2027
The New Hampshire city will begin distributing standardized trash and recycling carts in Pannaway Manor this November before deploying its first automated side-loader truck in spring 2027.
MONTREAL (RecyclingMonster): Portsmouth, New Hampshire, is preparing to modernize part of its residential trash and recycling system by introducing automated side-loader trucks and standardized wheeled carts.
The city's Department of Public Works will begin the transition in the Pannaway neighborhood, where new carts are scheduled to be distributed beginning in November 2026. Automated collection using the city's first side-loader truck is expected to begin in spring 2027.
The pilot will allow Portsmouth to test the system, identify operational issues and make adjustments before expanding automated collection to other parts of the city where street layouts can accommodate the larger collection equipment.
Homes Will Receive Separate 64-Gallon Trash and Recycling Carts
Participating households will receive two city-issued 64-gallon wheeled carts at no additional charge: one for household trash and one for single-stream recycling. Recycling carts will be identified by a blue lid.
Each cart will have a serial number associated with the property address and must remain with the property.
Portsmouth also plans to make 45-gallon and 96-gallon alternatives available in certain cases, including accommodations for older residents, larger households and residents with accessibility needs.
Mechanical Arms Will Replace Much of the Manual Lifting
Portsmouth currently uses rear-load packer trucks that generally require a driver and two sanitation workers to manually load trash and recycling.
The automated side-loader uses a mechanical arm to grab, lift and empty standardized carts into the truck.
The city says reducing manual lifting is intended to improve worker safety while allowing Public Works employees to be reassigned more easily to other highway and municipal operations when needed.
Portsmouth also said the staffing flexibility created by automated collection could support expanded transfer-station hours and a future swap shop.
Portsmouth Is Testing More Than a New Garbage Truck
The takeaway: The biggest operational change is not the mechanical arm itself. Portsmouth is redesigning the collection system around standardized carts, fewer manual lifts and routes that must physically accommodate automated equipment.
The pilot starts where automation is easiestPortsmouth is beginning in Pannaway because the neighborhood is considered more suitable for an automated side-loader. The city is not assuming the same truck can serve every street.
Compact neighborhoods such as the South End and Atlantic Heights are expected to continue using traditional rear-load trucks because their street layouts are less compatible with automated side-loader equipment.
Residents will have to change how they set out wasteAutomated collection requires more precision at the curb. Carts must be positioned with the opening toward the street, kept roughly three feet from other carts and obstacles, and placed where the lifting arm has sufficient horizontal and overhead clearance.
Trash left outside the city-issued cart will not be collected, and even cardboard must fit inside the recycling cart under the new system.
Portsmouth can learn from other city rolloutsRecyclingMonster reported earlier this year on Greenfield, Massachusetts, moving to automated recycling carts. By July, Greenfield reported its highest monthly recycling volume in a year and zero contamination days for the month.
That does not mean Portsmouth will see the same results, but it illustrates why municipalities increasingly treat cart standardization and automated collection as more than a labor-saving measure. The system can also change resident behavior, collection consistency and the amount of material that fits at the curb.
What to watch nextSpring 2027 will be the real test. Portsmouth will need to evaluate how the Pannaway route performs, how residents adapt to cart-placement requirements and whether the staffing and safety benefits justify expansion to additional automated-compatible neighborhoods.
Weekly Collection Will Continue
Portsmouth said regular collection days will remain unchanged and trash and recycling will continue to be collected once per week.
Single-stream recycling will also continue, although residents in automated areas will need to place all accepted recyclables inside the new recycling carts.
Existing carts and recycling bins that are incompatible with the new system can be taken to Portsmouth Public Works at 680 Peverly Hill Road for recycling.
The city plans to provide residents with educational materials before automated collection begins, including instructions on cart placement, clearance requirements and proper use of the new containers.
Portsmouth Automated Collection: What to Know
When will Portsmouth begin automated trash collection?
Portsmouth plans to begin automated side-loader collection in the Pannaway neighborhood in spring 2027. Cart distribution is scheduled to begin in November 2026.
What size carts will households receive?
The standard setup is one 64-gallon trash cart and one 64-gallon recycling cart per household.
Will collection days change?
No immediate change is planned. Weekly trash and recycling collection will continue on existing scheduled days during the pilot.
Can residents leave extra bags next to the cart?
No. Portsmouth says trash outside the automated cart will not be collected, and all materials must fit inside the appropriate city-issued container.
Will every Portsmouth neighborhood use automated trucks?
No. The city says some compact areas, including the South End and Atlantic Heights, are not considered suitable for automated side-loader trucks and will continue using traditional rear-load collection.
