 Antony Beamish, Managing Director for GRS Trading, said: “This major investment allows us to turn an industrial by- product into a high-quality construction aggregate, Enviroc. By also transporting this material by water we can achieve unparalleled environmental performance – an independent study suggests the carbon footprint is on average 47% lower than the equivalent primary aggregates. That makes Enviroc arguably the UK’s most sustainable aggregate. Using it in combination with low-carbon cement, for example, could produce the lowest carbon concrete achievable.
“We anticipate that Enviroc will change the way materials are specified on major construction jobs. Contractors can count on a consistent, quality product that meets specification and
at the same time know that it is the most sustainable aggregate there is – a UK-sourced, industrial by-product transported by water. It does not get better than that.”
Aggregates make up the single biggest volume of any materials needed for virtually every construction scheme, and London consumes about 10 million tonnes each year.
With recycling of demolition and excavation
waste virtually at its maximum in the
capital, GRS believes the way to further
improve the sustainability of aggregates is
to use secondaries and transport them as efficiently as possible. Last year GRS announced an exclusive deal to bring to market millions of tonnes of granite aggregate arising from British tungsten mine which has reopened in Devon.
Besides a marine wharf and processing plant at Tilbury, GRS is recommissioning a rail freight terminal to be able to transport secondary aggregates more widely across Greater London and the South East. Transporting aggregates by river and rail significantly reduces road miles and traffic congestion and represents a fraction of the carbon emissions of road haulage. It also frees up road vehicles to focus on ‘the last mile’ to deliver products to construction sites – and GRS runs one of the most modern, clean, and safe HGV tipper fleets in the capital, accredited to FORS Gold standard.
The inherent characteristics of granite mean that Enviroc is one of the most durable, versatile, and consistent secondary construction aggregates available. GRS is able to make and supply the vast majority of typical aggregate products including type 1 sub-base, 6F5, single sizes, coarse sand, mortar sand, etc.
 Enviroc also complies with the requirements of British Standards for use as concreting aggregate, as unbound and hydraulically bound aggregate in civil engineering works and road construction, in applications such as drainage trenches, earthworks and capping, and in bituminous materials and surface treatments for roads, airfields and other trafficked areas.
