Met de 8e-klassers bij Kids&Science en de 9e- en 10e-klassers en 12e-klassers in het Duurzaamheidsproject hebben we vooral ook de nadelen gezien van bio-diesel. Maar alle genoemde nadelen bestaan niet bij dit project in Mali. Misschien wel weer andere, als je goed leest...
Boeren in Mali krijgen er een extra inkomstenbron bij. Zij gaan de grondstof leveren voor bio-diesel. Met dank aan autoproducent Kia, het kennisinstituut KIT en de eigenschappen van de giftige plant jatropha.

According to the New York Times “But now a plant called jatropha is being hailed by scientists and policy makers as a potentially ideal source of biofuel, a plant that can grow in marginal soil or beside food crops, that does not require a lot of fertilizer and yields many times as much biofuel per acre planted as corn and many other potential biofuels. By planting a row of jatropha for every seven rows of regular crops, Mr. Banani could double his income on the field in the first year and lose none of his usual yield from his field. Poor farmers living on a wide band of land on both sides of the equator are planting it on millions of acres, hoping to turn their rockiest, most unproductive fields into a biofuel boom. They are spurred on by big oil companies like BP and the British biofuel giant D1 Oils, which are investing millions of dollars in jatropha cultivation.”
And, from an environmental perspective, here’s the kicker from the Wall Street Journal: “But unlike other biodiesel crops, jatropha can be grown almost anywhere — including deserts, trash dumps, and rock piles. It doesn’t need much water or fertilizer, and it isn’t edible. That means environmentalists and policy makers don’t have to worry about whether jatropha diverts resources away from crops that could be used to feed people.”
