Among nonedible feedstock, there are many crops and tree-borne oilseed plants, such as karanja, neem, and jatropha, which have been under­utilized due to the presence of toxic components in their oils. Most of them grow in underdeveloped and developing countries, where a biodiesel program would give multiple benefits in terms of generation of employment for rural people (farmers), leverage of starting many types of industries using by-products from biofuels, and so forth [47]. However, nonedible crops are very much ignored in most cases. They grow on, regardless, waiting for their energetic potential to be discov­ered. The key is to find crops or trees that need very little care, have high oil content, and are resistant to plagues and drainage. The foliage could be used as manure, giving an added value to the crop. In fact, most of the trees and crops mentioned in the following (karanja, neem, etc.) grow well on wasteland and can tolerate long periods of drought and dry conditions.
