Renting a dumpster is one of the easiest ways to manage waste during a renovation, cleanout, or construction project. But before you start tossing everything into your roll-off container, it’s important to know: not everything can legally or safely be thrown away.
Boston, like many cities, has strict regulations about what materials are allowed in dumpsters and violating these rules can lead to fines, removal delays, or even environmental hazards.
Here’s a clear guide to the top 7 items you should never throw into a dumpster in Boston and what you should do instead.

1. Hazardous Materials
Hazardous waste is strictly prohibited from dumpster disposal in Boston and across Massachusetts. This category includes items like:
- Paints and paint thinners
- Motor oils and automotive fluids
- Pesticides, herbicides, and fertilizers
- Cleaning chemicals
These materials are toxic to the environment and require special handling to dispose of safely.
Proper Disposal Tip:
Boston residents can often take hazardous waste to local Household Hazardous Waste Collection events. Check the City of Boston’s Public Works website for upcoming dates.

2. Electronics (E-Waste)
Old electronics commonly called e-waste are banned from landfills in Massachusetts. This includes:
- Televisions
- Computer monitors
- Laptops
- Cell phones
- Printers
Electronics contain metals and chemicals like lead and mercury that can be dangerous if not recycled properly.
Proper Disposal Tip:
Bring your electronics to a Boston recycling center, electronics retailer, or participate in an e-waste recycling event. Many companies offer free drop-off for items like old phones and computers.

3. Tires
Tires are another material you cannot throw into a dumpster. When left in landfills, tires can trap methane gas, creating a fire hazard and taking up valuable space.
Proper Disposal Tip:
Most tire retailers in Boston will accept used tires for recycling when you purchase new ones. Some automotive shops also offer tire disposal services for a small fee.

4. Appliances with Freon
Appliances such as refrigerators, freezers, air conditioners, and dehumidifiers often contain Freon, a refrigerant that must be professionally removed before disposal.
Proper Disposal Tip:
Contact Boston’s appliance recycling program or certified technicians who can safely remove Freon. Once the refrigerant is removed, many parts of the appliance can be recycled.

5. Batteries
Batteries from household AA batteries to car batteries pose serious environmental risks if thrown away improperly. Many types contain heavy metals like lead, cadmium, and lithium.
Proper Disposal Tip:
Boston has several battery recycling locations, including at hardware stores and electronics retailers. You can also participate in designated battery collection programs.

6. Mattresse
In Massachusetts, mattresses and box springs are banned from landfill disposal as part of the Mattress Recycling Law (effective November 2022). These items must be recycled because they contain valuable materials like steel, foam, and textiles.
Proper Disposal Tip:
Boston’s Public Works Department offers mattress recycling through scheduled pickups. You can also contact specialized mattress recycling companies for drop-off or pickup services.

7. Medical Waste
Medical waste including syringes, sharps, medications, and biological materials cannot be disposed of in dumpsters due to health and safety risks.
Proper Disposal Tip:
Boston residents should bring sharps and medications to designated disposal sites. Pharmacies and hospitals often have safe drop-off locations for unused prescriptions and sharps containers.
Why It Matters: Safe and Legal Dumpster Use
Knowing what you can and can’t throw into a dumpster isn’t just about avoiding fines it’s about protecting the environment and keeping your project on track.
Illegal dumping of prohibited items can cause:
- Delays in pickup and disposal.
- Additional charges from your dumpster rental company.
- Environmental contamination leading to legal action.
When in doubt, ask your Boston dumpster rental provider for a list of prohibited materials. Many companies also offer additional services or partnerships for safely disposing of restricted items.
