BACKGROUND Although switchgrass has been developed as a biofuel feedstock and its potential for bioethanol and bio‐oil from fast pyrolysis reported in the literature, the use of the seeds of switchgrass as a source of triglycerides for biodiesel production has not been reported. Similarly, the potential for extracting triglycerides from coffeeweed (an invasive plant of no current economic value) needs to be investigated to ascertain its potential economic use for biodiesel production. RESULTS The results show that coffeeweed and switchgrass seeds contain known triglycerides which are 983 and 1000 g kg −1 respectively of the fatty acids found in edible vegetable oils such as sunflower, corn and soybean oils. In addition, the triglyceride yields of 53–67 g kg −1 of the seed samples are in the range of commercial oil‐producing seeds such as corn (42 g kg −1 ). CONCLUSION The results also indicate that the two non‐edible oils could be used as substitutes for edible oil for biodiesel production. In addition, the use of seeds of switchgrass for non‐edible oil production (as a feedstock for the production of biodiesel) further increases the total biofuel yield when switchgrass is cultivated for use as energy feedstock for pyrolysis oil and biodiesel production. © 2016 Society of Chemical Industry
