The communication implemented could be based on different types of nudges, such as the communication of social information, i.e. information on the behavior of peers or on socially acceptable behavior, or, for example, communication on the concrete fate of household waste (e.g. fate of the compost produced) or the concrete use of financial gains associated with better sorting (e.g. financing of local collective projects). Other nudges could be proposed, based on an in-depth analysis of the literature and the results of a preliminary national survey that we are going to conduct among households on the obstacles and levers to sorting bio-waste and bringing it to the collection point.
