Oils with high triglyceride content and low free fatty acid levels yield the most biodiesel. Palm oil, soybean oil, and rapeseed oil generally have the highest output, but sunflower oil is also a top contender due to its clean-burning properties and high-quality yield. Using GlobeCore USB plants, even oils with moderate impurities can be processed efficiently. The system handles both virgin and waste oils, offering great versatility and maximizing biodiesel output across various feedstocks.
