The project “Think differently and act differently” (TD&AD) aims to sensitize and motivate families to adopt in the household a more friendly behavior towards the environment, moving from the consumerist economy (buy-use-throw) to the circular economy. It requires a collaboration between the members of a family (parents and children) a bridge between these different generations who only together can adopt a more environmentally friendly behavior. We considered that within this adult-child binomial some will come with pragmatism and experience and the others with the enthusiasm and openness to the new. Municipal waste is the result of the way of consumption in households and only through education and collaboration between organizations involved in education, environmental protection and local councils can it be achieved to reduce them.
