GRS has secured a deal to bring to market millions of tonnes of granite arising from British tungsten mining as sustainable construction aggregate.

The multi-million pound venture sees GRS join forces with Tungsten West, operators of recently reopened Hemerdon tungsten-tin mine near Plympton, Devon, to sell high-quality secondary aggregate and transport it nationwide by sea and rail.

By-products arising from mining are widely rated as one of the most sustainable sources of construction aggregate and transportation by sea and rail produces a fraction of the carbon emissions of the equivalent road journeys.

Tungsten is the hardest metal with the highest melting point and has numerous uses in electronics, manufacturing and an array of everyday objects. Hemerdon mine is internationally important because it is the world’s fourth largest tungsten reserve (and the second largest to comply with CRIRSCO standards) as well as being Europe’s only source of tungsten.


However mining tungsten also gives rise to thousands of tonnes of granite, ideal for a full range of secondary aggregates from bulk fill materials to single sizes for concrete and many other construction applications. GRS will use its well-established freight network – in particular rail and marine – to efficiently transport the aggregate to construction projects across the south of England and potentially further afield. The granite aggregates will be processed on site at Hemerdon helping to sustain a number of local jobs.

Jon Fisher, CEO of GRS Group, said: "This is a true symbiotic collaboration between two like-minded businesses with shared ambitions. Not only are we helping the UK to remain self-sufficient in essential minerals, but we’re also distributing them in the most sustainable way possible. GRS already trades and transports almost 20 million tonnes of construction materials every year – around half of which is from recycled or secondary sources – and this deal reinforces our whole ethos to make the best use of the UK’s available resources."
