Our project proposal entitled “Design of a methodology to assess the sustainability of remediation plans for contaminated soil” (acronym: REMEDISOST, 2016-2017) has been approved by IHOBE-Ecoinnovation Projects (Basque Government). The main objective of the project is to develop a robust, reliable and rigorous methodology to properly analyse and assess the sustainability of plans for the remediation of contaminated soils aimed at recovering the functionality of degraded sites according to the intended land use. The project has the following partners: GAIKER-IK4 (coordinator), NEIKER-Instituto Vasco de I+D Agrario, BC3 – Basque Centre for Climate Change, and AFESA MEDIO AMBIENTE, S.A. Apart from sustainable remediation options, this project will help us become familiar with the methodology of Life Cycle Assessment that will be applied during the assessment of the different remediation plans.
