economy and the regeneration of biodiversity. Recent regeneration projects reported that Olive trees culture can transform areas suffering from desertification into a thriving, healthy and productive ecosystem, increasing the flora and fauna, with numerous plants, birds and wild animals coming and residing.8 Natura-Tec is engaged to protect and
develop this age-old biodiversity. Our olive groves operate without irrigation, relying solely on rainwater, utilizing a limited amount of land and water resources, growing in difficult climatic conditions. Olive cultivation helps to reduce our environmental impact, thanks to strong capacity to absorb and store carbon dioxide, capturing greenhouse gases from the atmosphere. Olive trees are mainly cultivated in arid zones, supporting biodiversity and local communities. Olea europaea L. has been appreciated
historically first for its fruits and wood, and then for its oil. The olive oil has several uses, for eating and cooking, as well as for ointment, lighting, and medical uses, long before our era.9
Today, virgin olive oil is an important
component of the Mediterranean diet, valued for its beneficial properties for human health thanks to the high amounts of unsaturated fatty acids (mainly oleic acid), together with interesting minor component such as phenolic constituents, and squalene. The refined olive oil, limpid, colourless, odourless, neutral in taste, without contaminants, and with a higher smoke point, is better suited for high-heat cooking methods like frying and baking. Implanted in the heart of the olive
cultivation region, the APG Group has developed strong olive oil refining capacities, offering the benefits of a large-scale integrated supply chain supported by responsible sourcing and processing. During the physical refining (deodorisation and discoloration) process of the crude olive oil, substantial quantities of ‘waste’ are generated, and are in fact high added-value compounds, such as phospholipids, glycolipids, unsaponifiable matter (mainly squalene), waxes, pigments and carotenoids, tocopherols, phytosterols, hydrocarbons or triterpenoids. Thanks to an extra step of molecular distillation, we successfully isolate the olive

squalene, from the olive unsaponifiable concentrate, obtained from the waste of the refining process of the crude olive oil. Natura-Tec supplies, consequent volumes of the upcycled olive squalene or squalane (the hydrogenated version of the squalene). The Natura-Tec olive squalane is totally upcycled, obtained thanks to traditional farming, permanent native crops, with low water consumption, allowing to slow down erosion and desertification. Natura-Tec olive squalane is a true model of circular economy. Natura-Tec, is constantly striving to develop
more eco-awareness, producing natural, safe, and effective biocompatible ingredients, and keeping in mind that environmental protection is our ultimate goal. The development a more sustainable formula, that is truly beneficial for the environment; thanks to the use of sustainable emollients or actives; such as squalane from the upcycling process of the olive oil refining, or with oxygen positive actives; will more than ever make a positive difference for the planet.
