Indonesia[edit source | editbeta]

As of 2009, Indonesia was the largest producer of palm oil, surpassing Malaysia in 2006, producing more than 20.9 million tonnes.[58] Indonesia aspires to become the world's top producer of palm oil.[59] But at the end of 2010, 60 percent of the output was exported still in the form of Crude Palm Oil.[60] FAO data show production increased by over 400% between 1994 and 2004, to over 8.66 million metric tonnes.
In addition to servicing traditional markets, Indonesia is looking to put more effort into producing biodiesel. Major local and global companies are building mills and refineries, including PT. Astra Agro Lestari terbuka (150,000 tpa biodiesel refinery), PT. Bakrie Group (a biodiesel factory and new plantations), Surya Dumai Group (biodiesel refinery).[61]
Cargill (sometimes operating through CTP Holdings of Singapore, is building new refineries and mills in Malaysia and Indonesia, expanding its Rotterdam refinery to handle 300,000 tpa of palm oil, acquiring plantations in Sumatra, Kalimantan, the Indonesian peninsula and Papua New Guinea). Robert Kuok's Wilmar International Limited has plantations and 25 refineries across Indonesia, to supply feedstock to new biodiesel refineries in Singapore, Riau, Indonesia and Rotterdam.[61] In Kalimantan, the activity of palm oil companies endangers the living space ofIndigenous Tribes,[62] and orangutans. [63]
The Aceh governor issued a permit in August 2011 for Indonesian palm oil firm PT Kallista Alam to develop some 1,600 hectares in Tripa.[64]
Indonesian Palm oil producer Triputra Agro Persada will reportedly increase its planted area by about two-thirds from 2013 by 2015.[65]

Malaysia[edit source | editbeta]

In 2012, Malaysia, the world's second largest producer of palm oil,[66] produced 18.79 million tonnes of crude palm oil on roughly 5,000,000 hectares (19,000 sq mi) of land.[67][68] Though Indonesia produces more palm oil, Malaysia is the world's largest exporter of palm oil having exported 18 million tonnes of palm oil products in 2011. China, Pakistan, the European Union, India and the United States are the primary importers of Malaysian palm oil products.[69]
In 2012, the Malaysian palm oil industry employed an estimated 491,000 workers.[68]
Malaysia's Sime Darby is the largest listed palm oil company globally, based on plantation area and fresh fruit bunch production.[70] The company was created through a Malaysian government initiated merger in December 2006.[71][72] The world's second-largest oil palm plantation company, Felda Global Ventures Holdings (FELDA), is also based in Malaysia.[73][74]

Nigeria[edit source | editbeta]

As of 2011, Nigeria was the third-largest producer, with more than 2.5 million hectares (6.2×106 acres) under cultivation. Until 1934, Nigeria had been the world's largest producer. Both small- and large-scale producers participated in the industry.[75][76]

Thailand[edit source | editbeta]

produced 1.3 million tonnes of crude palm oil on roughly 5,700,000 hectares proposes to expand land use for exportable cash crops to 10,000,000 hectares in 2027

Colombia[edit source | editbeta]

In the 1960s, about 18,000 hectares (69 sq mi) were planted with palm. Colombia has now become the largest palm oil producer in the Americas, and 35% of its product is exported as biofuel. In 2006, the Colombian plantation owners' association, Fedepalma, reported that oil palm cultivation was expanding to 1,000,000 hectares (3,900 sq mi). This expansion is being funded, in part, by the United States Agency for International Development to resettle disarmed paramilitary members on arable land, and by the Colombian government, which proposes to expand land use for exportable cash crops to 7,000,000 hectares (27,000 sq mi) by 2020, including oil palms. Fedepalma states that its members are following sustainable guidelines.[77]
Some Afro-Colombians claim that some of these new plantations have been expropriated from them after they had been driven away through poverty and civil war, while armed guards intimidate the remaining people to further depopulate the land, while coca production and trafficking follows in their wake.[78]

Other producers[edit source | editbeta]

Benin[edit source | editbeta]

Palm is native to the wetlands of western Africa, and south Benin already hosts many palm plantations. Its 'Agricultural Revival Programme' has identified many thousands of hectares of land as suitable for new oil palm export plantations. In spite of the economic benefits, Non-governmental organisations (NGOs), such as Nature Tropicale, claim biofuels will compete with domestic food production in some existing prime agricultural sites. Other areas comprise peat land, whose drainage would have a deleterious environmental impact. They are also concerned genetically modified plants will be introduced into the region, peopardizing the current premium paid for their non-GM crops.[79][80]

Cameroon[edit source | editbeta]

Cameroon has a production project underway initiated by Herakles Farms in the US.[81] However, the project has been halted under the pressure of Greenpeace, WWF and other civil society organizations in Cameroon. Before the project was halted, Herakles left the Roundtable on Sustainable Palm Oil (RSPO) early on in negotiations. The project has been controversial due to opposition from villagers and the location of the project in a biodiversity hotspot.[82][83]

Kenya[edit source | editbeta]

Kenya's domestic production of edible oils covers about a third of its annual demand, estimated at around 380,000 metric tonnes. The rest is imported at a cost of around US$140 million a year, making edible oil the country's second most important import after petroleum. Since 1993 a new hybrid variety of cold-tolerant, high-yielding oil palm has been promoted by the Food and Agriculture Organization of the United Nations in western Kenya. As well as alleviating the country's deficit of edible oils while providing an important cash crop, it is claimed to have environmental benefits in the region, because it does not compete against food crops or native vegetation and it provides stabilisation for the soil.[84]

Ghana[edit source | editbeta]

Ghana has a lot of palm nut species, which can become an important contributor to the agriculture of the region. Although Ghana has multiple palm species, ranging from local palm nuts to other species locally called agric, it was only marketed locally and to neighboring countries. Production is now expanding as major investment funds are purchasing plantations, because Ghana is considered a major growth area for palm oil.

Weaving is a textile production method which involves interlacing a set of longer threads (called the warp) with a set of crossing threads (called the weft). This is done on a frame or machine known as a loom, of which there are a number of types. Some weaving is still done by hand, but the vast majority is mechanised.
Knitting and crocheting involve interlacing loops of yarn, which are formed either on a knitting needle or on acrochet hook, together in a line. The two processes are different in that knitting has several active loops at one time, on the knitting needle waiting to interlock with another loop, while crocheting never has more than one active loop on the needle.
Spread Tow is a production method where the yarn are spread into thin tapes, and then the tapes are woven as warp and weft. This method is mostly used for composite materials; Spread Tow Fabrics can be made in carbon,aramide, etc.
Braiding or plaiting involves twisting threads together into cloth. Knotting involves tying threads together and is used in making macrame.
Lace is made by interlocking threads together independently, using a backing and any of the methods described above, to create a fine fabric with open holes in the work. Lace can be made by either hand or machine.
Carpets, rugs, velvet, velour, and velveteen are made by interlacing a secondary yarn through woven cloth, creating a tufted layer known as a nap or pile.
Felting involves pressing a mat of fibres together, and working them together until they become tangled. A liquid, such as soapy water, is usually added to lubricate the fibres, and to open up the microscopic scales on strands of wool.
Nonwoven textiles are manufactured by the bonding of fibres to make fabric. Bonding may be thermal or mechanical, or adhesives can be used.
Bark cloth is made by pounding bark until it is soft and flat.


Textiles can be made from many materials. These materials come from four main sources: animal (wool, silk), plant (cotton, flax, jute), mineral (asbestos, glass fibre), and synthetic (nylon, polyester, acrylic). In the past, all textiles were made from natural fibres, including plant, animal, and mineral sources. In the 20th century, these were supplemented by artificial fibres made from petroleum.
Textiles are made in various strengths and degrees of durability, from the finest gossamer to the sturdiest canvas. The relative thickness of fibres in cloth is measured in deniers. Microfibre refers to fibres made of strands thinner than one denier.

Synthetic textiles

Synthetic textiles are used primarily in the production of clothing.
Polyester fibre is used in all types of clothing, either alone or blended with fibres such as cotton.
Aramid fibre (e.g. Twaron) is used for flame-retardant clothing, cut-protection, and armor.
Acrylic is a fibre used to imitate wools, including cashmere, and is often used in replacement of them.
Nylon is a fibre used to imitate silk; it is used in the production of pantyhose. Thicker nylon fibres are used in rope and outdoor clothing.
Spandex (trade name Lycra) is a polyurethane product that can be made tight-fitting without impeding movement. It is used to make activewear, bras, andswimsuits.
Olefin fibre is a fibre used in activewear, linings, and warm clothing. Olefins are hydrophobic, allowing them to dry quickly. A sintered felt of olefin fibres is sold under the trade name Tyvek.
Ingeo is a polylactide fibre blended with other fibres such as cotton and used in clothing. It is more hydrophilic than most other synthetics, allowing it to wick away perspiration.
Lurex is a metallic fibre used in clothing embellishment.
Milk proteins have also been used to create synthetic fabric. Milk or casein fibre cloth was developed during World War I in Germany, and further developed in Italy and America during the 1930s.[14] Milk fibre fabric is not very durable and wrinkles easily, but has a pH similar to human skin and possesses anti-bacterial properties. It is marketed as a biodegradable, renewable synthetic fibre.[15]
Carbon fibre is mostly used in composite materials, together with resin, such as carbon fibre reinforced plastic. The fibres are made from polymer fibres through carbonization.

Plant textiles[edit source | editbeta]

Grass, rush, hemp, and sisal are all used in making rope. In the first two, the entire plant is used for this purpose, while in the last two, only fibres from the plant are utilized. Coir (coconut fibre) is used in making twine, and also in floormats, doormats, brushes, mattresses, floor tiles, and sacking.
Straw and bamboo are both used to make hats. Straw, a dried form of grass, is also used for stuffing, as is kapok.
Fibres from pulpwood trees, cotton, rice, hemp, and nettle are used in making paper.
Cotton, flax, jute, hemp, modal and even bamboo fibre are all used in clothing. Piña (pineapple fibre) and ramie are also fibres used in clothing, generally with a blend of other fibres such as cotton. Nettles have also been used to make a fibre and fabric very similar to hemp or flax. The use of milkweed stalk fibre has also been reported, but it tends to be somewhat weaker than other fibres like hemp or flax.
Acetate is used to increase the shininess of certain fabrics such as silks, velvets, and taffetas.
Seaweed is used in the production of textiles. A water-soluble fibre known as alginate is produced and is used as a holding fibre; when the cloth is finished, the alginate is dissolved, leaving an open area
Lyocell is a man-made fabric derived from wood pulp. It is often described as a man-made silk equivalent and is a tough fabric which is often blended with other fabrics – cotton for example.
Fibres from the stalks of plants, such as hemp, flax, and nettles, are also known as 'bast' fibres.

Animal textiles[edit source | editbeta]

Animal textiles are commonly made from hair, fur or skin.
Wool refers to the hair of the domestic goat or sheep, which is distinguished from other types of animal hair in that the individual strands are coated with scales and tightly crimped, and the wool as a whole is coated with a wax mixture known as lanolin (aka wool grease), which is waterproof and dirtproof[citation needed]. Woollen refers to a bulkier yarn produced from carded, non-parallel fibre, while worsted refers to a finer yarn which is spun from longer fibres which have been combed to be parallel. Wool is commonly used for warm clothing. Cashmere, the hair of the Indian cashmere goat, andmohair, the hair of the North African angora goat, are types of wool known for their softness.
Other animal textiles which are made from hair or fur are alpaca wool, vicuña wool, llama wool, and camel hair, generally used in the production ofcoats, jackets, ponchos, blankets, and other warm coverings. Angora refers to the long, thick, soft hair of the angora rabbit. Qiviut is the fine inner wool of the muskox.
Wadmal is a coarse cloth made of wool, produced in Scandinavia, mostly 1000~1500CE.
Silk is an animal textile made from the fibres of the cocoon of the Chinese silkworm which is spun into a smooth fabric prized for its softness. There are two main types of the silk: 'mulberry silk' produced by the Bombyx Mori, and 'wild silk' such as Tussah silk. Silkworm larvae produce the first type if cultivated in habitats with fresh mulberry leaves for consumption, while Tussah silk is produced by silkworms feeding purely on oak leaves. Around four-fifths of the world's silk production consists of cultivated silk.[12]

Mineral textiles[edit source | editbeta]

Asbestos and basalt fibre are used for vinyl tiles, sheeting, and adhesives, "transite" panels and siding, acoustical ceilings, stage curtains, and fire blankets.
Glass fibre is used in the production of spacesuits, ironing board and mattress covers, ropes and cables, reinforcement fibre for composite materials, insect netting, flame-retardant and protective fabric, soundproof, fireproof, and insulating fibres.
Metal fibre, metal foil, and metal wire have a variety of uses, including the production of cloth-of-gold and jewellery. Hardware cloth (US term only) is a coarse weave of steel wire, used in construction. It is much like standard window screening, but heavier and with a more open weave. It is sometimes used together with screening on the lower part of screen doors, to resist scratching by dogs.
