Water recycling
A silt de-watering system has been installed which enables water to be recycled and minimises the use of borehole water. In turn, the costs of silt disposal are reduced.
The de-watered silt can be handled as a 'solid' and is disposed of at a local quarry, meeting the waste management conditions of the quarry operator licence. The silt is transported as 'back loads' to the quarry which optimises transport costs and reduces the environmental impact of haulage.
As a result of this system, the moisture control of the silt slurry has been reduced significantly with an approximate saving of water in excess of 2,000m3/per year.
In addition rainwater harvesting is in place at our Keele plant to recycle rain water for use in the production process.
