This ACR+ lunchtime webinar aimed to provide public authorities and technical staff in charge of waste prevention with practical tools to help them assess and monitor their waste prevention actions. Based on ACR+ reseach and the results of European projects, the training focused in particular on the webtools developed in the framework of Miniwaste (LIFE) and Pre-waste (INTERREG IV C) projects. These webtools aim to help local and regional authorities take the right decision beforehand and follow-up on the effectiveness of their waste prevention strategies.
