    Their Australian and New Zealand Growers
    "All of our wool comes from Australia and New Zealand, and, specifically, from the Merino Sheep that inhabit these beautiful lands.
    We are committed to non-invasive farming: knowing that Merino sheep are highly adaptable, we let them graze vast areas freely in their natural manner, with minimal human intervention.
    A typical Thermowave Merino station covers about 1 hectare and supports about 5000 to 15000 Merino sheep.
    Ensuring this much space creates a quiet, calm, and stress-free environment, in which sheep can feel happy and free.
    ‍This allows all of our farms to operate sustainably and free from scouring methods as well as to produce higher quality wool fibers."
    "To guarantee sustainable and responsible production, we build our manufacturing cycle on long-term contracts with experienced and trustworthy wool growers.
    Such established and time-tested partnerships make it easier our growers to plan for future fiber demand and offer certainty through stable income, helping them better manage their flocks. In turn, we get a stable source of quality wool at a set cost.
    Our growers manage their farms according to holistic and integrated environmental standards and international best practices.
    They not only set the global quality standards for processing wool but also continue to improve them through innovation in grazing, animal husbandry, shearing, and fostering natural livestock living conditions.
    Our business is built on the protection and promotion of the five fundamental freedoms of an animal :
    - Freedom from hunger or thirst by ready access to fresh water and a diet to maintain full health and vigor
    - Freedom from discomfort by providing an appropriate environment including shelter and a comfortable resting area
    - Freedom from pain, injury or disease by prevention or rapid diagnosis and treatment
    - Freedom to express (most) normal behavior by providing sufficient space, proper facilities and company of the animal's own kind
    - Freedom from fear and distress by ensuring conditions and treatment which avoid mental suffering.
    Additionally, all of our growers are mandated to abide a strict requirement that all wool in our products must be non-mulesed.
    Farm Examples :
    "Haddon Rig, one of our larger farms, is a mixed-farming property covering 60 000 acres of fertile land near the town of Warren, in the heart of Central West NSW, comprising Haddon Rig, Braemar, and Boomanulla.
    Privately owned by the Falkiner family: George B S Falkiner, his wife Sally, and their four daughters, Eleanor, Grace, Olivia, and Florence, who live on the property together with a small close-knit staff.
    ‍Employing talented and hard-working personnel, utilizing best practice management and state-of-the-art technology, Haddon Rig is a premier example of the "un-subsidized" modern Australian agriculture.
    Mount Hesse farm, known equally for its rich history and its future-oriented farming practices, is one of the largest producers of Merino wool in Australia.
    The original sheep introduced to the farm in the 1840s were small Saxon merinos with short wool and light fleeces.
    Today, the farm has 7000 merino ewes and merino rams to form a self-replacing flock and 3500 merino ewes.
    Mount Hesse is managed according to holistic and integrated environmental standards and international best practices.
    It continuously improves its operation through applied innovations in grazing, animal husbandry, shearing, and fostering natural livestock living conditions.
    Mount Hesse is situated on volcanic soils, which are naturally low in phosphorous, a necessary nutrient in productive pastures.
    To make the best use of the natural fertility without overdependence on the application of fertilizer, only deep-rooted perennial grasses are established in the new pasture.
    The deep root systems of these grasses extract nutrients unavailable to shallow-rooted annuals and therefore minimize the need for the application of the increasingly scarce and expensive phosphorous fertilizer.
    A diverse mix of pasture and feed species, with different growth cycles, is utilized to help manage seasonal feed fluctuations, including Lucerne and summer-active fescue grasses.
    Such diversity, coupled with rotational grazing means we can manage animal health and nutrition without over-grazing, thereby maximizing animal, pasture and soil health."
