The plant makes its cement using local chalk and clay taken from different areas of the same quarry. Around 3,000 tonnes of chalk and 1,000 tonnes of clay are needed each day. Two kilns heat the raw materials to 1400 degrees Celsius – a temperature at which steel would melt. The gases and dust from the kiln are subjected to an intense filtering and scrubbing process before being safely emitted to the atmosphere.
While traditional fossil fuels – coal and petcoke – still have a role to play, South Ferriby is increasingly using more sustainable and cost-effective alternative fuels. It has been successfully using Secondary Liquid Fuel (SLF) made from industrial liquid wastes that can’t be recycled since 2002. More recently, it has added Climafuel, a fuel made from household waste that is processed to a tight specification. It reduces landfill and saves fossil fuels for future generations.
The plant delivers its vital end-product by road over a wide area of eastern, central and northern England. It also ships cement from Grimsby to Leith on the east coast of Scotland.
The cement plant currently employs 150 people and is very much a part of the wider community. In total, the company’s annual contribution to the local economy through wages, rates and the buying of services adds up to some £10 million.
