What is an oil palm tree?
The oil palm (Elaeis guineensis) is an African tree in the palm family (Arecaceae), grown in West and Central Africa, Malaysia, and Indonesia. Reaching about 20 meters (66 feet) in height, it features tiny flowers on short branches that grow into clusters of oval fruits. The tree is cultivated for its fruits and seeds, which yield palm oil and palm kernel oil, respectively.
Palm oil is used in producing soaps, cosmetics, candles, biofuels, and lubricating greases. Palm kernel oil is used in manufacturing edible products such as margarine, ice cream, and pharmaceuticals. The residue left after extracting the kernel oil serves as cattle feed.

Where does the oil palm tree grow naturally?
The oil palm (Elaeis guineensis) is native to West and Central Africa, where it grows widely in the tropical forest zones. It is now also extensively cultivated in Malaysia and Indonesia. The oil palm is grown for palm oil, which is obtained from its fruits, and palm kernel oil, which comes from the seeds.

What does the oil palm tree look like?
The oil palm (Elaeis guineensis) is an African tree cultivated for its oil. It can reach about 20 meters (66 feet) in height and bears a single stem. Its many tiny flowers grow on short branches, developing into large clusters of oval fruits about 4 cm (1.6 inches) long. Ripe fruits are black with a red base and contain a single oily seed called a kernel.
Palm oil, extracted from the fruits, has various applications, including soap, cosmetics, and biofuels. Palm kernel oil, derived from the seeds, is used in edible products like margarine and chocolate. The industry's rapid expansion has led to deforestation in regions like Indonesia and Malaysia, threatening native species and contributing to air quality issues.

How are palm oil and palm kernel oil made from oil palm trees?
Both palm oil and palm kernel oil are derived from the fruits of the oil palm tree (Elaeis guineensis). Palm oil is extracted from the outer fleshy part of the fruit, while palm kernel oil comes from the seed, or kernel.
For commercial production, palm oil is obtained by steaming the outer fleshy portion of the fruit to deactivate enzymes, followed by pressing. Palm kernel oil is extracted from the kernels through mechanical screw presses. Alternatively, solvent extraction can be employed for a more thorough oil recovery from the seeds and nuts.

Why is palm oil important in food and products?
Palm oil, derived from the fruit of the oil palm, is globally significant due to its versatile applications. Palm oil is used in the manufacturing of soaps, cosmetics, candles, biofuels, and lubricating greases. Palm kernel oil, extracted from the seed, is used to make margarine, ice cream, chocolate, cookies, bread, and pharmaceuticals. The residue from kernel oil extraction serves as cattle feed. Besides their economic importance, palms are also planted as ornamentals in warm regions and indoors.

What environmental issues are linked to growing oil palm trees?
Growing oil palm trees is linked to several environmental issues, including deforestation, which has important global consequences. Forests store carbon, and when they are burned for oil palm plantations, this carbon is released into the atmosphere as carbon dioxide, a greenhouse gas, contributing to climate change.
Additionally, the expansion of oil palm farming leads to habitat fragmentation and biodiversity loss, threatening native plants and animals like orangutans in Indonesia. Slash-and-burn practices for new plantations also contribute to poor air quality in Southeast Asia.

Oil palm, (Elaeis guineensis), African tree in the palm family (Arecaceae), cultivated as a source of oil. The oil palm is grown extensively in its native West and Central Africa, as well as in Malaysia and Indonesia. Palm oil, obtained from the fruits, is used in making soaps, cosmetics, candles, biofuels, and lubricating greases and in processing tinplate and coating iron plates. Palm kernel oil, from the seeds, is used in manufacturing such edible products as margarine, ice cream, chocolate confections, cookies, and bread, as well as many pharmaceuticals. The cake residue after kernel oil is extracted is a cattle feed. The plant is also grown as an ornamental in many subtropical areas.
The oil palm bears a single stem and reaches about 20 metres (66 feet) in height. It has many tiny flowers crowded on short branches that develop into a large cluster of oval fruits some 4 cm (1.6 inches) long. When ripe, the fruits are black with a red base and feature a single oily seed known as the kernel.
For commercial oil production, the outer fleshy portion of the fruit is steamed to destroy the lipolytic enzymes and then pressed; the resulting palm oil is highly coloured because of the presence of carotenes. The kernels of the fruit are pressed in mechanical screw presses to recover palm kernel oil, which is chemically quite different from the oil from the flesh of the fruit.

The commercial palm oil industry rapidly expanded in the late 20th century and led to the deforestation of significant swaths of Indonesia and Malaysia as well as large areas in Africa. New plantations are often formed using slash-and-burn agricultural methods, and the resulting fragmentation of natural forests and loss of habitat threatens native plants and animals. Bornean and Sumatran orangutans are especially iconic species threatened by the expansion of oil palm farming in Indonesia. In addition to driving biodiversity loss, the slash-and-burn practices of oil palm cultivation have contributed significantly to poor seasonal air quality in parts of Southeast Asia. Although attempts have been made to certify sustainably grown palm oil, corporate buyers have been slow to support those endeavours; some environmental groups have urged individuals to avoid products with palm oil altogether.
The American oil palm (Elaeis oleifera) is native to Central and South America and is sometimes cultivated under the erroneous name Elaeis melanococca. Unlike the African oil palm, the trunk of the American oil palm creeps along the ground and bears flat leaves. Both the American oil palm and the maripa palm (Attalea maripa) are used to obtain palm oil in some areas. The oil of the American oil palm was probably used for making candles by the early American colonizers.
