Growing energy crops on contaminated land for biofuels and soil remediation
Soil pollution is a global problem making vast areas of agricultural land unexploitable
In Europe it is estimated that
because of excessive concentrations of organic or inorganic pollutants.
GOLD develops solutions to grow lignocellulosic crops on contaminated sites
Grow energy crops on contaminated land
- Optimization of high-yielding lignocellulosic crops for phytoremediation
- Pilot field trials on polluted sites in EU, China and India
- Optimization of phytoremediation for organic and inorganic soil pollutants
Produce low ILUC risk biofuels
- Biomass pre-treatment, gasification and fermentation
- Biomass pyrolysis and upgrading to refinery-compatible intermediates and fuels
- Extraction of pollutants in concentrated forms
Optimize the value chain
- Integrated environmental, economic, social assessment
- Modelling of the selected value chains
- Design of effective replication strategies
Four high-yielding lignocellulosic energy crops are used:
miscanthus, switchgrass, sorghum and industrial hemp.
They have been chosen on the following criteria:
- They grow rapidly and are tolerant to contaminants and other stresses.
- They are non-food crops with high biomass yields (10-25 t/ha) and low input requirements.
- They can provide feedstock for advanced biofuels with low ILUC risks.
GOLD aims to bring forward positive impacts to several global societal challenges
Bring polluted land back to agricultural production through improved phytoremediation, thus contributing to a zero pollution toxic-free environment.
Produce low ILUC risk biofuels on contaminated land for a clean, affordable and secure energy.
Promote international collaboration towards the Mission Innovation Challenge 4 on advanced biofuels.
