Wool fibre is an abundant, renewable, natural keratin material produced by sheep. According to the International Wool Textile Organisation (IWTO, 2024), in 2021 there were around 1.95 million tonnes of raw wool produced globally by around 1.2 billion sheep (from about 1000 breeds). As measured by raw wool prices, the market value of global wool production was estimated at USD 38.97 billion in 2024 and is expected to reach USD 45.61 billion by 2029, growing at a CAGR of 3.20% during the forecast period (2024–2029) (Mordor Intelligence, 2024). However, for non-Merino fine wools produced in some countries like the UK, the value of wool is low (Promar International, 2024). The total annual value of UK wool in recent years has been around £20 to £30 million, with income from wool making up less than 3% of overall revenue from sheep production in 2019, due to the low fleece value and higher shearing costs (BWMB, 2023). This leads to a question of how to make wool production more sustainable. In the UK, the low value of wool has led a number of sheep farmers to change breeds to wool shedders (Wiltshire Horn, Easycare and Exlana) to avoid the cost of shearing and the management and welfare costs associated with fully fleeced sheep.
