Outside waste in Puerto Rico landfills: the ban that admits no exceptions

Last reviewed: August 24, 2026VerifiedDRNA

In short

Act 424-2000 establishes as public policy the conservation, maximum extension of useful life and greatest possible yield from all solid waste handling and disposal facilities, and to that end prohibits the handling and disposal, in all landfills and sanitary landfills in Puerto Rico — of the Government, its departments, agencies, instrumentalities, public corporations and municipalities, and any other state, municipal or private subdivisions or entities, including similar facilities or facilities of any kind — of any solid waste generated outside Puerto Rico’s jurisdiction. The law adds that this prohibition shall admit no exceptions or regulatory provisions, municipal ordinances or contracts to the contrary. However, solid waste discharged in Puerto Rico by or from cruise ships, aircraft and any other type of maritime or air vessel in regular passenger or cargo transportation service to or from Puerto Rico, generated incidentally to that service and discharged at Puerto Rico’s sea or air ports, shall be understood as generated within Puerto Rico, permitting its final disposal in those landfills. Nor shall recyclable materials defined by law or regulation that are transported to Puerto Rico specifically for the purpose of being recycled or processed at recycling, treatment or processing facilities located on the Island be considered solid waste for this law’s purposes. Any person who violates the law commits a misdemeanor and shall be fined five thousand (5,000) dollars.

What is it?

It is the law that closes Puerto Rico’s landfills to waste generated outside the island. What stands out is how it is written: it does not merely prohibit, it expressly says the prohibition shall admit no exceptions or regulation, municipal ordinance or contract to the contrary. That is, a contract authorizing otherwise does not defeat it.

Who can do it?

The prohibition reaches all landfills and sanitary landfills in Puerto Rico, whether of the Government, its departments, agencies, instrumentalities, public corporations and municipalities, or of any other state, municipal or private subdivisions or entities, including similar facilities or facilities of any kind. The penalty reaches any person who violates it.

Step by step

  1. Step 1: The prohibition reaches private landfills too

    The article enumerates on purpose: handling and disposal is prohibited at all landfills and sanitary landfills in Puerto Rico, its departments, agencies, instrumentalities, public corporations and municipalities, “and any other state, municipal or private subdivisions or entities, including landfills and sanitary landfills and similar facilities or facilities of any kind.” There is no back door through private ownership.

  2. Step 2: No regulation, ordinance or contract defeats it

    It is the sentence that gives this law its force: “This prohibition shall admit no exceptions or regulatory provisions, municipal ordinances or contracts to the contrary.” If someone tells you a municipality authorized it by ordinance or that there is a contract permitting it, the text answers that directly.

  3. Step 3: The cruise and aircraft carve-out, and its fit

    It is narrow and the law builds it as a fiction: solid waste discharged in Puerto Rico by or from cruise ships, aircraft and any other type of maritime or air vessel “in regular service” of passenger or cargo transportation to or from Puerto Rico, generated “incidentally to that service” and discharged at Puerto Rico’s sea or air ports, shall be understood as generated within Puerto Rico’s jurisdiction, permitting its final disposal in those landfills. Three conditions at once: regular service, incidental generation, and discharge at PR ports.

  4. Step 4: Recyclables imported to be recycled are not waste

    The law clarifies it in its own article: for its purposes, recyclable materials defined by law or regulation that are transported to Puerto Rico specifically for the purpose of being recycled or processed at recycling, treatment or processing facilities located on the Island shall not be considered solid waste. The word “specifically” does the work.

  5. Step 5: The fine

    Any person who violates this law commits a misdemeanor and, upon conviction, shall be fined five thousand (5,000) dollars. The law fixes the figure, not a range.

  6. Step 6: Where to take it

    The law creates no complaint procedure and designates no enforcing agency. In practice there are two routes: the environmental complaint before the Department of Natural and Environmental Resources, which we cover in its own guide, and a report to the Police since it is a misdemeanor. Note date, place, facility and any information about the waste’s origin.

Where to do it

The Department of Natural and Environmental Resources is the environmental door for a complaint; the Puerto Rico Police, the criminal one. It is worth saying that this particular law names neither: it creates the prohibition and the offense. If your matter is coal ash, that is another law with its own guide and a much larger fine; if it is recycling in a housing complex or of electronic equipment, those also have their own guides.

What to do if something goes wrong

What we did not read and what we therefore do not assert. The recyclables carve-out refers to materials “defined by law or by regulation to that effect,” and we read neither that solid waste statute nor the regulation defining them; so we publish no list of what counts as recyclable material. Nor did we read any Department of Natural and Environmental Resources regulation on manifests, permits or cargo inspection, so we do not describe how waste origin is proven in practice. The law designates no agency to enforce it and creates no complaint procedure: we say that as a limit of the statute, not as a gap of ours. And a clarification about the cruise and aircraft carve-out: it is not a general authorization for waste arriving by ship or plane, but for waste generated incidentally to a regular passenger or cargo transportation service to or from Puerto Rico and discharged at its ports.

Common mistakes

  • Believing a contract or municipal ordinance can authorize it: the law says it admits no contrary contracts or ordinances.
  • Thinking it applies only to public landfills: it also reaches private ones and similar facilities of any kind.
  • Stretching the cruise and aircraft carve-out: it requires regular service, incidental generation and discharge at PR ports.
  • Assuming everything arriving to be recycled is outside: it must be recyclable material defined by law or regulation and brought specifically for that.
  • Looking in this law for an enforcing agency or complaint procedure: it carries none.
  • Reading the fine as a range: the law fixes five thousand dollars.

Frequently asked questions

No. The prohibition covers all landfills and sanitary landfills in Puerto Rico, including those of private entities and similar facilities or facilities of any kind.

Can a contract authorize it?

The law answers directly: this prohibition shall admit no exceptions or regulatory provisions, municipal ordinances or contracts to the contrary.

What about cruise ship waste?

Waste discharged by or from cruise ships, aircraft and any other maritime or air vessel in regular passenger or cargo transportation service to or from Puerto Rico, generated incidentally to that service and discharged at Puerto Rico’s sea or air ports, shall be understood as generated within Puerto Rico.

What is the fine?

Any person who violates this law commits a misdemeanor and shall be fined five thousand (5,000) dollars.
