The import terminal in Kent represents a £2.5m investment by the Irish cement producer to help it step up its exports to the UK.
Its first UK bulk import facility in Runcorn opened in early 2016 and the launch at Sheerness will allow it to supply a further 250,000 tonnes of its cement substitute, which is made with ground granulated blast furnace slag (GGBS).
Both import terminals have been developed in partnership with Peel Ports.
Ecocem Ireland managing director Micheál McKittrick said: “Our second investment in the UK in a state-of-the-art import facility demonstrates to the market the need for the low carbon cement alternative and the growing demand from the UK construction industry.
“We have already engaged in long term agreements with major concrete manufacturers in the UK and will continue to build momentum in the coming months”.
