Making use of waste products
Our operational activities inevitably produce a range of waste products, many of which have the potential to be recycled.
At present we recycle all of our sludge using anaerobic digestion and lime stabilisation techniques to create a biosolid product for agricultural use. We have also invested in creating energy from waste and currently have seven operational CHP (Combined Heat and Power) plants.
Part of our long-term strategy is to further develop each of these activities.
We are currently working with our supply chain partners to minimise the amount of waste on construction sites and make use of by-product materials such as rock, grit, plastics and other materials.
Furthermore, we continue to take steps to reduce the amount of waste sent to landfill through the recycling and composting of grit and screenings (solid materials extracted in the early stage of wastewater treatment).
In particular we are using grit in our land restoration activities, such as those at Park and Stannon lakes on Bodmin Moor in Cornwall.
