This deliverable will define the Sustainability Assessment Model for all the solutions involved in the project as well as calculating the baseline of every pilot using this model. Each section will have a brief description of the specific characteristics of the waste management systems of each pilot, the general and specific objectives, the methodology used and the main results. When necessary an appendix will be used to include all the supplementary information. When necessary an appendix will be used to include all the supplementary information. This deliverable will set the basis of comparison to follow the progress of the project in terms of KPIs for the four pilots. However, as in this stage the methodology is still being implementing some corrections or updates (specially regarding the data) may be necessary in the future. Any change that may arise in the KPI methodology or in the update of the data will be updated in the subsequent monitoring reports (from D1.4 to D1.7).
