Bio-diesel is a renewable energy source produced from natural materials. It is often derived from oils or fats obtained from plants or animals. Among the plant options provided, Jatropha is known for its high oil content, making it a significant source for bio-diesel production.
Jatropha curcas, commonly referred to simply as Jatropha, is a drought-resistant perennial that grows well in marginal soils. The seeds of the Jatropha plant contain a high percentage of oil, which can be processed to produce bio-diesel. This makes Jatropha a sustainable option for fuel, particularly in areas with poor agricultural conditions.
Plant | Bio-diesel Potential |
