17 May Recycled IBA used at the Rivenhall IWMF and Energy Centre site
Posted at 09:45h in Uncategorized
As part of the site development works of the Rivenhall IWMF and Energy Centre, 20,000 tonnes of Incinerator Bottom Ash Aggregate (IBAA) is being used on site in the construction of site access roads and piling mats. Incinerator Bottom Ash (IBA) is produced by Energy from Waste plants and is composed of the inert, non-combustible fraction of the waste processed through the plant. Before the IBA is used on site it has been processed to remove metals and is graded into different fractions that can be blended with virgin aggregate for various construction uses.
IBAA is a sustainable alternative to the quarrying of virgin aggregate and makes use of waste that would otherwise go to landfill, turning it instead into a valuable resource.
Once the Rivenhall IWMF and Energy Centre is operational, the IBA produced will be processed into IBA Aggregate for use in construction projects elsewhere. This is one of several ways that value can be recouped from residual waste in the form of materials and energy, contributing towards the circular economy.
