Trash Collection

Public Works

The Department of Public Works (DPW) provides free weekly trash collection to most residential buildings. The program is dictated by the City’s Refuse & Litter Ordinance, which requires residents to do the following:

  • Place trash in City-issued carts, only. The cart must be fully closed at all times. Trash may not be spilling out of the top of the cart.
  • Carts may not exceed 50 pounds.
  • On the occasion that you have excess trash that won’t fit in the cart, you may place one bag of trash out per week. The bag must be a heavy-duty contractor trash bag (at least 3mils thick). No thin kitchen trash bags.
    • Place bag next to trash cart between 5:00 a.m. and 7:00 a.m. on collection day
    • Bags cannot contain food waste.
    • Bags must weigh less than 50 pounds.
  • Owners have up to 15 days to replace broken (including receptacles broken due to rodent damage) or lost receptacles. Owners are required to fill out this form to request a replacement.
  • Items that don’t require a permit but don’t fit into a cart or overflow bag are considered a bulky waste item. Examples include a couch, table, or chair (unless they’re made of metal). Each household is permitted to place one piece of bulky waste for trash collection each week.
  • Carts may be placed at the curb after 6:00 p.m. the night before collection or by 7:00 a.m. on collection day.
  • After collection, carts must be removed from the curb by 6:00 p.m.
  • Owners must label their carts with their address.

Violations of these rules may result in a fine up to $300 per violation per day.

To find out if something can be kept out of the trash use the Get Rid of It Right tool below.

Public Works has two compliance officers who check the collection routes daily to ensure compliance with the Refuse and Litter Ordinance.

My cart is missing or broken.

If your cart is missing, please check up and down your street first. Please request what carts you would like picked up or delivered at CambridgeMA.Gov/RecycleSupplies and we will be in touch. Be sure to write your address on the side of each of your carts.  

My Compost/Recycling/Trash/Yard Waste was not picked up on my regular collection day

All waste must be set out by 7AM on your collection day, or after 6PM the night before. If you think any waste collection was missed, please report it at CambridgeMA.Gov/311 (preferred) or leave a voicemail at 617-349-4800. Leave materials at the curb and pickup will be done by the end of the next collection day.


What size cart(s) do I have? What are the cart sizes?

We offer trash cart in three sizes (35-gallon, 45-gallon, and 65-gallon) based on the number of households in a building.

You can find the size of a trash cart by looking at the first two numbers in the serial code on the back of the cart (e.g., “4522...” is a 45-gal cart)

See this PDF for the dimensions of the carts. 

Why is 45 gallons of trash per household the standard cart size for residents?

In 2026, City Council updated the Refuse & Litter Ordinance which dictates trash policy. The limit of 45-gallons per household was set based on data from City audits of curbside trash volume. In those audits, the City found the average household produces 23 gallons of trash per week after diverting recyclables, food waste, and other items that must be kept out of the trash.

After using the curbside recycling, food waste, and yard waste, we invite you to use our Get Rid of It Right Tool to look up what to do with other waste items such as textiles, batteries, electronics and more. Or, download the Zero Waste Cambridge app (iOS|Android). Residents use it more than 300 times per day.

On the rare occasions when you need to set out extra trash, you can set out one heavy-duty contractor trash bag. Bags must be at least 3 mils thick (e.g., contractor bags). Bags cannot exceed 50 gallons or 50 pounds. No thin grocery or kitchen bags allowed. Trash bags may be placed at the curb after 5 a.m. on collection day, not the night before. Food waste is not permitted in the plastic bags as it attracts rodents.

What is prohibited in the trash?

The Refuse & Litter Ordinance dictates solid waste policy and the following items are banned from trash disposal in Cambridge:

  • Recyclables
  • Food Waste**
  • Leaves and yard waste 
  • Textiles (i.e. clothes, sheets, towels)
  • Large Appliances
  • Metal items (i.e. filing cabinets, furniture)
  • Lead acid batteries and other non-alkaline batteries (i.e. lithium-ion, NiCAD, etc)
  • Mattresses  
  • Mercury-containing equipment and lamps 

 

**=Banned starting February 3, 2027
