Copaifera langsdorffii

Copaifera langsdorffii , also known as the diesel tree , is a tropical rainforest tree. It has many names in local languages, including kupa’y , cabismo , and copaúva . [1] : 5

Biological description

C. langsdorffii is a medium-sized to large 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 qui well into the oil seeps and Where It Can Be Easily file Managed. The tree does not grow well outside the tropics . [1] : 8

Uses

Biodiesel use

The diesel tree produces terpene hydrocarbons in its woods and leaves, and this source of renewable energy . [1] : 10 According to early cited anecdotal reports, the tree could be tapped for 40 liters (11 US gal) of oil, and an acre of 100 mature trees could produce 25 barrels of oil annually. [1] : 4 These deferrals Were the carried in 2007 by Australian media after-year Australian citizen in Mackay, Queensland imported seeds of the plant in hopes of growing diesel fuel in Australia. [2] However, a 2003 study showed that the actual yields of oleoresinare small diameter, with diameter at breast height (DBH) of 35 centimeters, produce no oil at all; and medium sized trees (DBH between 55-65) produced more than large trees (DBH greater than 65). No more than 1 liter (0.26 US gal) of fuel. [3] A 2006 study by Oliviera et al. agreed with the 2003 study, and further found that the best time to tap the trees in spring. [1] : 10 Summarizing these findings, a report by the Hawaii Department of Agriculture stated: “[ C. langsdorffii ‘s] likelihood as an efficient producer of readily extractable oleoresins appears very slim.” [4]

The main compound in the oil is copaiba (15%), an oleoresin which is useful in the production of such products as lacquers and can be used as biodiesel . After filtration, this oil can be used in the engine of a regular automotive diesel. [1] : 10 Some natives have been reported to use the fuel for cooking. [1] : 9

Wood uses

The wood is highly resistant to natural decay, and as such is used in carpentry where the tree is native. [1] : 9

Pollen collector

European honey bees are strongly attracted to the tree for its pollen, making it a mainstay of Brazilian beekeeping . [1] : 11

Medical

Natives in the Amazon uses the oil collected from the tree as a traditional medicine, primarily as an expectorant and antiseptic , but also for the treatment of skin diseases such as eczema and dermatosis . [1] : 9-10
