What to do with the fruit residue from oil palm seeds: refine it into bio-ethanol or use it as fertilizer?
When oil is harvested from the seeds of the oil palm tree, the fruit residue can be used to make bio-ethanol. However, it can also be used as a fertilizer on palm tree plantations; which option is best for the environment? Edi Wiloso compared the two green options at the Institute of Environmental Sciences Leiden (CML). His PhD defence is scheduled for 29 October.
