In 2008, 66 % of biodiesel in Europe got here from rapeseed, 13 % from soybean and 12 % from palm oil (Junginger et al., 2014). Moreover probably the most outstanding oil crops (palm, soybean, rapeseed and sunflower), many different crops akin to, canola, mustard, flax, jatropha, coconut, hemp, and pennycress are good assets of oil.
Using corn oil can be gaining momentum in the US, the place massive volumes of maize are utilized in ethanol manufacturing. Corporations akin to Corn Oil One are growing enhancements to crude corn oil to facilitate conversion into biodiesel. Progressive applied sciences for separation of corn oil are included on the method innovation web page.
Within the EU, issues over iLUC and the Meals vs. Gasoline debate have led to proposals to restrict biofuel manufacturing from meals crops to 7 % (see proposed adjustments to the Renewable Vitality Directive and Gasoline High quality Directive). This has accelerated curiosity in drought-resistant oil crops that may be cultivated on marginal lands and don’t compete with meals crops.
Nevertheless, there are doubts solid on the validity of the assumptions made and fashions used to underpin the iLUC debate. For instance, in Germany in early 2015, UFOP revealed a brochure Alternative or danger for the longer term!? presenting a extra optimistic outlook on the advantages provided by Rapeseed and different oil crops.
