Ketura (קטורה, Ktora) is a kibbutz north of Eilat in the Arabah rift valley. It has approximately 130 members and 150 children (including adult offspring). About one third of the members are native Israelis, with the rest coming from the United States, Canada, England, South Africa, Australia, Spain, France, Latin America, Switzerland, the Netherlands and the former Soviet Union.
Agriculutural enterprises of the kibbutz include a date orchard and a dairy herd. The kibbutz has a large cow shed for milk production, but it is most famous for its guest house and educational center (Karen Kolot) and its Algae plant. The algae plant (Algatech) processes haematococcus algae through a filtration system in order to extract natural astaxanthin. The extract is then sold around the world as a natural high-quality ingredient for fish food; as a natural pigment for use in cosmetics, and as a nutraceutical.
There is cooperation with other kibbutzim in the area in additional pursuits such as the regional date-packing plant and Ardag, a large fish hatchery near Eilat. Ketura also operates a carpentry shop. Many members do, however, work outside the kibbutz in professional fields such as teaching, accounting, and bookkeeping.
The Arava Institute for Environmental Studies (AIES), is also located here. The institute promotes regional cooperation between Israelis, Palestinians, and residents of other neighboring Arab countries in environmental matters. It also researches and draws attention to some of the ecological problems in the region, as well as researching the desert ecosystem.
