- Jatropha (Wikipedia.org)
"As with many members of the family Euphorbiaceae, Jatropha contains compounds that are highly toxic."
"Goldman Sachs recently cited Jatropha curcas as one of the best candidates for future biodiesel production. It is resistant to drought and pests, and produces seeds containing 27-40% oil, averaging 34.4%. The remaining press cake of jatropha seeds after oil extraction could also be considered for energy production. However, despite its abundance and use as an oil and reclamation plant, none of the Jatropha species have been properly domesticated and, as a result, its productivity is variable, and the long-term impact of its large-scale use on soil quality and the environment is unknown." 12-10
- Jatropha for Biofuel (Reuters.com)
"Oilseed plant jatropha does not offer an easy answer to biofuels problems as some countries hope, because it can be toxic and yields are unreliable, experts and industry officials warned on Wednesday."
"The woody plant can grow on barren, marginal land, and so is increasingly popular in countries such as China that are keen to boost biofuels output but nervous about food security."
"But its nuts and leaves are toxic, requiring careful handling by farmers and at crushing plants, said experts at an oils and fats conference."
"In addition, it is a labour-intensive crop as each fruit ripens at a different time and needs to be harvested separately. Its productivity is also low and has yet to be stabilised." 12-10
