Hemp has a long but interrupted history in South Tyrol and Tyrol. Among linen and flax, hemp was traditionally grown to produce high quality fibres for mooring ropes, sails and paper. In the 1960s, a loss of image of the plant brought also a loss of knowledge about its cultivation and utilization. Nowadays, it regains importance, because of its favourable ecological balance and extraordinary qualities. Hemp requires neither pesticides nor fertilizers or genetically modified seeds to grow. While one kilo of cotton needs approximately 5000 litres of water, hemp is more sufficient: the plant in the Salewa Garden (of the Carmagnola variety) has grown more than 4 metres high between May and September 2020 – with fewer than 300 ml water though rainfall – and produced more than 14 tons of biological mass. Moreover, hemp improves the soil quality with its roots by extracting contaminants, preventing erosion at the same time. And last, hemp provides habitat and nutrition for many insects and thus contributes greatly against bee mortality.
The hemp plant could be one of the REAL problem solvers regarding climate crisis: In comparison to conventional cotton and virgin synthetics, the powerful combination of a high biomass and the rapid growing of the hemp plant assures this natural fibre to be an important carbon storage. The biomass of the hemp plant can be considered as CO2 negative and contributes therefore in a very important way to reduce our carbon footprint. Additionally, the hemp plant does not require the use of pesticides and in the middle latitudes the plant grows without watering. Furthermore, the hemp plant enhances biodiversity and soil health. We could observe all of this very well during this hot summer 2022 in our own little hemp field at our headquarters, with our hemp growing over 4 meters high without watering, in only 120 days!
The variety of use cases became apparent in the presentation of the products in front of the Salewa Garden of the Oberalp Group: Christine Ladstaetter displayed Salewa’s Alpine Hemp Collection. Hemp is the strongest regrowing (natural) fibre and, especially when wet, a lot more resistant than cotton (2.5x) or polyester (1.4x). The mountain sport industry makes use of the resistance and excellent transpiration abilities of the fibre. Innovation around cultivation and use, such as composites, were presented by Valentine Troi of the Standortagentur Tyrol; Werner Schönthaler explained the benefits of hemp as insulation and building material; Helmuth Profanter brought a typically South Tyrolean bread (Schüttelbrot) and protein bars made with hemp; and Christoph Kirchler had cremes, handmade CBD (cannabidiol) extracts, high quality cosmetics and dietary supplements on hemp basis, which could be tested.
