The global carbon fibre and composites market is on a strong growth trajectory, with some estimates projecting it could reach $45 billion by 2032. This expansion is being driven by rising demand for high-performance, lightweight materials across industries such as transportation, renewable energy, and sporting goods.
Despite this, the sector faces a significant environmental challenge, as around 90% of carbon fibre waste is currently sent to landfill and only a small fraction is recycled into lower-value applications. At the same time, the production of virgin carbon fibre is highly carbon-intensive, generating more than 30 kilograms of CO2e per kilogram produced. As sustainability and regulatory pressures increase, the recycled carbon fibre segment is emerging as the fastest-growing part of the market.
Lineat Composites is addressing this challenge by transforming waste carbon fibre into a high-performance and circular material. The company has developed an automated fibre alignment technology that repurposes chopped carbon fibre waste into highly aligned tapes using a process inspired by papermaking. They use a unique two-stage alignment process that ensures uniform fibre orientation by aligning fibres on a specialised surface before securing them into position through vacuum water removal and a binder.
This approach overcomes the scalability and thickness limitations of competing methods, producing a material that retains up to 80% of the performance of virgin carbon fibre while offering greater formability. From a sustainability perspective, Lineat’s recycled material delivers a footprint that is just 15% of its virgin equivalent, positioning it as both an environmentally and commercially compelling alternative.
To date, Lineat has gained strong traction through partnerships with leading companies, including Jaguar Land Rover and GKN Aerospace, as well as collaborations with major sporting goods companies such as Wilson, Head, and Bauer. With growing demand from blue-chip customers, Lineat is now focused on scaling its production capacity to meet increasing market interest and accelerate adoption across industries.
