Energy efficiency

Energy performance certificates


As part of our work towards The Carbon Trust Standard, an Energy Performance Certificate system has been developed for all our asphalt plants*.

Grading every plant from A-G, the system ensures all units are moving towards an A grade - with individual improvement plans in place. (A being the most efficient) An industry first, the scheme is being considered by the Mineral Products Association with a view to creating new standards across all asphalt plants in the UK.

The ratings show how efficiently energy is used at each site. The numbers alongside the rating show units of energy used per tonne of output per year. The UK average is 111 kWh/tonne/ year.
