Gentle remediation options (GRO) include various and in general plant-based options to remediate trace element contaminated soils (TECS) at low cost and without significant negative effects for the environment. Although GRO comprise very innovative and efficient technologies, they are still not widely used as practical site solution due to several hindrance reasons. Greenland has been launched on January 1 2011 to address several issues: - Sustainable management adapted to TECS and deployment of GRO at field scale; - Valorisation of plant biomass produced on trace element (TE) -contaminated sites; - Harmonization of methods to assess the bioavailability of TE and development of a tool set to monitor the sustainability of GRO; - Improving GRO through plant selection and modifications in soil TE bioavailability; - Appraisal of current GRO practice, and development of implementation guidance and decision support frameworks. Various current gaps / shortfalls in GRO application and development, i.e. lack of rigorous large-scale applications of GRO, variability in methods used for analysis and appraisal, potential for increasing the efficiency of GRO through biotechnology, technologies for biomass valorization and their uncertainty, bestpractice guidances for the application of GRO at field scale, including appraisal of the various options available and their uncertainty, methods for monitoring, development and evaluation of a decision support tool (DST) focused on GRO, which can be integrated into existing, well-established and utilized DSTs / decision-frameworks, etc. are addressed. The overall aim of GREENLAND is to make GRO fit for purpose, which will substantially contribute to improvement of soil quality and ecosystem services on the local level (land owners, communities), but also at the European level. In addition to that, the use of biomass produced on GRO-treated contaminated land will contribute to socio-economic development at the local level and help to fulfil the increasing demand for biomass use in raw ...
