D4.3 – Report on "Screening-and comparison of industrial crops grown on contaminated land"

Contaminated land, that is unsuitable for food production, represents an alternative option for crops producing feedstock for bioproducts and bioenergy, which would otherwise be in competition with food production. It has been estimated that there are more than 10 million major contaminated sites worldwide, while in the European Economic Area (EEA)-39 countries the registered contaminated sites are up to 650000. Even though often perceived solely as a problem, contaminated areas could instead become a real asset that needs to be valued. One of the aims of MAGIC project was to screen the most promising industrial crops for cultivation on contaminated and saline soils. The effects of the heavy metals Cd, Pb, Ni and Zn on fifteen industrial crops were examined, namely on: biomass sorghum, camelina, cardoon, castor bean, crambe, Ethiopian mustard, giant reed, hemp, lupin, miscanthus x giganteus, pennycress, safflower, switchgrass, tall wheatgrass, and wild sugarcane (African fodder cane). The experiments were conducted following the same methodology and protocols by all partners involved.
