Copaifera langsdorffii, also known as the Diesel Tree,[1] Rashed Tree, and Salam tree[citation needed] is a tropical rainforest tree. It has many names in local languages, including kupa'y, cabismo, and copaúva.

Biological description[edit]

C. langsdorffii is a medium-sized tree usually reaching 12 m (39 ft) in height, with white flowers and small, oily fruits. The wood is light due to its porosity, and it is honeycombed with capillaries filled with oil. Tapping the tree involves cutting a well into which the oil seeps and where it can be easily collected. Despite its vigorous production of oil, the tree does not grow well outside of the tropics. It has potential to be a reliable source of biodiesel in tropical climates,[citation needed] but the tree does not thrive in colder or more temperate climates.


Biodiesel use[edit]

The diesel tree can be tapped every six months for more than 20 l (5.3 US gal) of fuel, and it will continue producing for around 70 years. One acre with around 100 mature (15-20+ years old) trees would produce up to 25 barrels of diesel per year which could sustain the fuel needs of small farms, about 40 l (11 US gal) per tree per year.[2][unreliable source?]

Wood uses[edit]

The wood can be burned for firewood or used in carpentry.

Pollen collector[edit]

Bees utilize the tree for pollen collection.[clarification needed]
