The cardoon is a thistle related to the artichoke and thus is known as the 'artichoke thistle'. It is found in such countries as Argentina, Australia, and United States and is considered a weed. In 2005, Europe launched the BIOCARD research project to look into using cardoon as a
source. BIOCARD's objectives are to determine how much cardoon has to be grown to be viable, the cost to process its seeds into fuel, and if the resulting fuel is indeed cost effective. GAIKER-IK4, a participating organization within BIOCARD, is also looking into all aspects of
production to simplify it as well as process any waste matter.
