# Celtic Minerals Limited

Celtic Minerals is a Cardiff-based green technology company transforming industrial waste into high-value recycled materials. The business processes fly ash from the defunct Aberthaw Power Station—a byproduct of coal combustion—into innovative sustainable products for construction, manufacturing, and environmental applications.

The company serves multiple sectors: construction and concrete manufacturers seeking to reduce carbon emissions; polymer producers requiring cost-effective, high-performance fillers; and industries requiring activated carbon for filtration, medical, and environmental purposes. Their primary geographic focus is the South East of England for cement replacement products, whilst their advanced polymer compounds target the model railway and 3D printing markets.

What distinguishes Celtic Minerals is their proven, rigorously tested technology backed by 15 years of research and validation from Imperial College London and Cardiff University. Their proposed 900,000-tonne annual processing capacity at Aberthaw would address a 17.5-million-tonne waste challenge whilst creating 100 direct jobs and 3,400 secondary positions over 30+ years. The venture delivers substantial environmental impact: processing waste ash reduces cement production by one-third per concrete unit and saves over 500,000 tonnes of CO₂ annually.

The company aligns strategically with Welsh Government priorities for carbon neutrality, business innovation, and economic regeneration. Their products maintain competitive pricing against virgin materials whilst offering superior recycled credentials, making them attractive to environmentally conscious manufacturers and construction firms.
