Environmental Managers Register and RENTRI: what a waste carrier must do

The Register and RENTRI perform different functions

The National Register of Environmental Managers concerns the authorisation required to carry out certain waste collection and transport activities, with categories, classes, vehicles and requirements.

RENTRI concerns waste traceability and the digital obligations laid down by the legislation, including the chronological register, the FIR and data transmission in the cases provided for.

For a haulage company the correct check is therefore not “am I registered with the Register?” but: am I correctly registered with the Register, am I correctly registered with RENTRI, and am I managing the register and the FIR according to the applicable rules?

• National Register of Environmental Managers: authorisation for collection and transport (categories, classes, vehicles, requirements)
• RENTRI: digital traceability (chronological register, FIR, data transmission)
• The two systems are linked but do not replace one another

Registration with the Register does not mean registration with RENTRI

No. Registration with the Register must not be confused with registration with RENTRI. RENTRI uses information from the Register to qualify certain profiles, but this does not mean that RENTRI obligations are automatically fulfilled by the Register.

The business must access RENTRI and manage the obligations provided for its own profile, checking its position in relation to both systems.

Which carriers are affected by RENTRI

The parties subject to the obligation include businesses carrying out professional waste collection or transport activities within the framework set out in Articles 188-bis and 189 of Legislative Decree 152/2006 and in Ministerial Decree 59/2023.

The position must in any case be checked on the basis of the activity actually carried out and of the specific registration with the Register.

• Category 1
• Category 4
• Category 5
• Category 6
• Category 4-bis and subcategory 2-ter
• Other activities subject to specific regimes

The Register: what a carrier must check

Even before talking about RENTRI, the business should check that its registration with the Register is consistent with the transport it intends to carry out. A perfectly completed FIR does not make legitimate a transport carried out with a vehicle, or for waste, that is not covered by the authorisation.

• Category and class
• Authorised EWC codes
• Registered vehicles and requirements
• Validity of the registration
• Technical Manager, where required
• Changes in the business or in the vehicle fleet

Category 4 and category 5: what is the difference

Category 4 concerns the collection and transport of non-hazardous special waste; category 5 concerns hazardous special waste.

The two categories must not be confused. The presence of an EWC code in the company's list must be checked together with the actual classification of the waste and with the conditions of the registration.

What changes for carriers with RENTRI

For carriers, RENTRI mainly affects the chronological loading and unloading register, the FIR and data transmission to the Register. For certain transport activities involving hazardous special waste, vehicle geolocation is also required.

• Chronological loading and unloading register
• Digital FIR
• Data transmission, where required
• Vehicle geolocation for the transports concerned

Chronological register: when a carrier must keep it

Where subject to the obligation, yes: for carriers required to register with RENTRI, the register is kept in digital format. The register can be managed with interoperable management software or with the RENTRI services, provided the procedure allows the obligations to be met.

Digital FIR from 16 September 2026: what really changes

From 16 September 2026 the transitional period that allows operators registered with RENTRI to use the paper FIR as an alternative to the digital one comes to an end.

But the format of the FIR depends on the position of the producer/holder and determines the method used by the whole chain. If the producer is subject to the digital FIR, the carrier continues digitally; if the producer is not registered with RENTRI and stays on paper, a registered carrier also handles that movement on paper.

From 16 September carriers must be able to manage correctly both digital flows and, where they apply, paper ones.

Who decides whether the FIR is on paper or digital

It is not the carrier who chooses freely. During the transitional regime, the choice between paper and digital was up to the producer/holder in the cases provided for; from 16 September it must be checked whether the producer/holder is subject to digital issuance. Once the format is determined, the whole chain continues with that method.

• Digital FIR → the carrier and the recipient manage it digitally
• Paper FIR → the carrier and the recipient manage it on paper

What a carrier must do with a digital FIR

In the ordinary flow the carrier must acquire or view the FIR, check its information, add the data within its own remit and sign digitally, manage the journey, deliver the waste and verify that the flow has been completed.

• Acquire or view the FIR
• Check the information within your own remit
• Add the necessary data (transport, driver, registration plate, date and time)
• Sign digitally
• Manage the FIR during the journey and any events that occur
• Deliver the waste to the recipient and verify completion

Data transmission to RENTRI: it concerns hazardous waste

For digital FIR notes relating to hazardous waste, producers, carriers and recipients registered with RENTRI must transmit the prescribed data to the Register in the applicable manner. For non-hazardous waste, the same obligation must not be extended automatically.

Note: transmitting data does not mean sending a PDF. RENTRI is a structured system: the prescribed information must be transmitted according to the technical specifications, and the management software must be configured correctly.

Geolocation: which carriers are affected

Parties subject to RENTRI that transport hazardous special waste must ensure, in the cases provided for, geolocation systems on their vehicles. For category 5 motor vehicles dedicated to the transport of hazardous special waste, the presence of the system is a requirement of technical suitability.

The rules were updated in 2026 (Resolution No. 1 of 24 March 2026 and Circular No. 2 of 27 March 2026). Motorcycles, trailers and semi-trailers are excluded: the check must be made vehicle by vehicle.

For vehicles already registered, the deadline for the adaptation application was 30 June 2026; from 1 July 2026 the Register has provided for the ex officio cancellation of vehicles that have not been adapted.

Practical cases

The same carrier may handle a digital FIR on Monday and a paper FIR on Tuesday, depending on the producer it collects from. A category 5 carrier must also check that its geolocation is compliant. The fact that RENTRI technically allows a form to be prepared does not make a transport authorised if the vehicle is not suitable for that EWC code.

• Producer registered with RENTRI → digital FIR managed digitally by the whole chain
• Producer not registered → paper handling, even for a registered carrier
• Category 5 → check the FIR, the registration, the requirements, geolocation and data transmission
• EWC code not authorised for the vehicle → the Register check must be made before departure

The 7 checks before departure

Before departure, for every movement: the waste, the Register registration, the producer, the FIR, the recipient, RENTRI and any additional obligations (geolocation, ADR, transboundary documentation, DIWASS).

• 1. Check the waste
• 2. Check the Register registration
• 3. Check the producer (applicable FIR method)
• 4. Check the FIR
• 5. Check the recipient
• 6. Check RENTRI
• 7. Check the additional obligations

The most common mistakes

The biggest risk is treating each obligation as separate from the others. Before departure the following must be consistent: the waste, the Register authorisation, the vehicle and the RENTRI/FIR documentation.

• Thinking that the Register and RENTRI are the same registration
• Thinking that from 16 September every FIR must be digital
• Relying on the management software without checking the authorisation
• Confusing the digital FIR with data transmission
• Thinking that all vehicles must have geolocation
• Leaving the whole RENTRI process to the driver without company procedures
