Construction materials supplier GRS has secured an exclusive deal to bring to market millions of tonnes of granite arising from British tungsten mining for use as sustainable construction aggregate.
The multi-million pound agreement 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.
But 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.”
Max Denning, CEO of Tungsten West, said: “Tungsten West is extremely excited to partner with GRS, especially as they’re the UK’s leading aggregates trading company with an exceptional reputation for success. By GRS applying their years of experience and success across all industry verticals within the construction materials sector, Tungsten West can offer a significant new mineral resource, at scale, to the UK market. GRS brings a wealth of experience, credibility and strategic thinking that complements our approach.”
Starting this month (September 2021) GRS expects to ramp-up secondary aggregate volumes from Hemerdon to distribute more than a million tonnes each year for the next decade and beyond. After a short lorry journey from Hemerdon, the aggregate will be loaded onto ships at Plymouth for transportation to other ports around Britain. The aggregate will also be hauled a short distance by road to nearby Marsh Mills (between Plymouth and Plympton) where it can be loaded onto trains for onward distribution via the rail network.
Through its Cornish subsidiary Maen Karne and London-based business Walsh, the GRS Group already successfully transports secondary granite from the Cornish china clay industry into London by sea and rail. By volume aggregates represent the single biggest flow of materials in the UK economy.
