Main updates of MUD 2026
As outlined in the Summary of MUD 2026 Amendments published by MASE, the changes made to the current model were necessary to align with new regulatory provisions. The main update concerns the section related to the Municipal Waste and waste collected under municipal agreements Declaration, through the introduction—within Form RU (Municipal Waste Collection) – point 10.1.2.2 Separate Collection—of specific information on selective collection performed by municipalities through eco-compactors under agreements with EPR schemes or other entities. This change is intended to improve and monitor data related to the selective collection of plastic bottles via eco-compactors.
Other amendments align the new format with the rules of the new RENTRI waste traceability IT system. In particular: Form AUT has been updated to align authorisation types indicated in the MUD with those provided by RENTRI; descriptions of physical states in Form RIF and in the Simplified Declaration have been updated; the annex Instructions for completing the Single Environmental Declaration Model (MUD) has been amended in sections 7.1, 9.1, 9.2 and 9.3 to specify that the calculation to be carried out by operators must be kept at the local unit, aligning with RENTRI requirements.
Lastly, in the Secondary Materials Form, the term “recycled aggregates” has been replaced with “recovered aggregates”, in order to align the terminology with the Decree of the Minister of the Environment and Energy Security of 28 June 2024, No. 127, “Regulation on end-of-waste criteria for inert waste from construction and demolition, and other inert waste of mineral origin, pursuant to Article 184-ter, paragraph 2, of Legislative Decree No. 152/2006.”
