The Technical Annex for wood packaging waste governs conventions for the transfer of relative packaging waste. By signing the Convention the Municipality, or its official delegate, agrees to transfer its packaging waste to Rilegno. The Consortium chain therefore issues payments based on the quantity and quality of the transferred packaging waste. There are two quality classes, the first containing extraneous fractions of up to 2.5%, the second of up to 5%. Beyond the 5% extraneous content fraction there is no economic compensation. The annex presents the procedures used to varify the quality of the transferred materials. The annex also covers the possibility of specific local agreements governing the transfer of other wood waste materials together with wood packaging. As with all conventions set forth in the Framework Agreement, is possible to cancel the agreement by September 30th of each year, with validity from as of the next January 1st, and re-enter the convention according to the same time schedules.
