Abstract
Abstract
Soil contamination represents a major global environmental threat. Only in the European Union, around 340.000 contaminated sites are inventoried. At the same time, the need to foster the uptake of sustainable biofuels to curb greenhouse gas emissions from the transport sector is one of the pillars of the EU’s climate action to achieve the overarching goals set under the European Climate Law and the Renewable Energy Directive. Against this backdrop, nature-based solutions for soil remediation are increasingly being advocated as sustainable options to enhance soil biodiversity while addressing soil contamination in line with the UN Sustainable Development Goals and, in the EU, the European Green Deal and the EU Biodiversity Strategy for 2030. Among several nature-based soil remediation techniques, phytoremediation consists of the use of plants and their associated microbes to stabilise, degrade, volatilise and extract soil pollutants. Furthermore, the non-food biomass generated as a result of phytoremediation could provide a meaningful low Indirect Land Use Change (iluc) feedstock for the production of advanced biofuels to reduce climate change.
This paper addresses the policy and legal background surrounding the uptake of phytoremediation and recovery of output materials focusing on existing roadblocks currently hampering the full-scale adoption of such a complex yet inherently circular value chain. The paper concludes that meaningful steps must yet be taken to properly embed nature-based soil remediation techniques, such as phytoremediation, in the current legal framework and to ensure social ownership of the same to maximise its environmental benefits.
