Goodbye to glasses, plates and plastic packaging. Or to those piles of no longer useful material that is always stacked up every time it gets rid of. Not to mention the petrol generators that are still seen, for example, in fairs and markets. Or the catering leftovers that end up in the dustbin. Welcome green events, therefore: after many, but sporadic, initiatives, the Municipality puts pen to paper the criteria for organizing concerts, fairs, sporting events, conferences or any type of event so that they are low-impact.
