From 16 September 2026, paper-format waste identification forms (FIR) are no longer permitted. All entities registered with RENTRI must submit the digital FIR (xFIR) exclusively. The temporary extension granted by the “Mille-proroghe” decree expired on 15 September 2026. As of the following day, penalties for failure to transmit — or incomplete transmission of — FIR data to RENTRI now apply.
What RENTRI is and who must comply
RENTRI is the national digital system for waste traceability, established under Article 188-bis of Legislative Decree 152/2006. It digitalises existing environmental compliance obligations: issuing waste transport identification forms and maintaining chronological loading and unloading registers. Among those required to register are small initial producers of special hazardous waste, who were enrolled from 15 December 2025. Until 15 September 2026, these operators could still issue paper FIRs as an alternative to the digital format. That option has now ended definitively.
The producer’s chosen format binds the entire waste chain
The format selected by the waste producer or holder determines how the entire supply chain must operate. If the producer issues a digital FIR, all other parties in the chain — carriers and recipients — must also handle it digitally. Conversely, if the producer chose a paper FIR (an option available only until 15 September 2026), the whole chain was required to use the same paper format. From 16 September, the paper format is no longer available to any obligated party.
How the digital FIR works
The digital FIR (xFIR) is authenticated via a unique code assigned by the “RENTRI FIR Digitale” mobile app. From 5 August 2026, the application is supported exclusively on mobile devices running Android 10 or later and iOS 16 or later. Operators using older devices must therefore update them before carrying out any waste movement operations.
Penalties in force from 16 September 2026
Failure to register — or irregular registration — with RENTRI carries an administrative fine of between €500 and €2,000 for non-hazardous waste and between €1,000 and €3,000 for hazardous waste. The same penalty ranges apply to incomplete or late transmission of the required data. In addition, any unpaid prior-period contributions remain due. Criminal liability applies where the conduct constitutes a criminal offence under applicable law.
