IBA Aggregate

IBA Aggregate

IBA Aggregate is produced from energy recovery facilities from nonrecyclable domestic waste which would have in the past been sent to landfill.  The process releases the energy potential in waste so that it can be utilised to generate electricity via combustion, this will deliver significant environmental, social and economic benefits to the community.
IBA Aggregate is a sustainable and accepted alternative to Type 1, 6F4 and 6F5 capping and consists of fused clinker, ceramics, glass, stone and concrete.  It has been widely used in construction for over 20 years and has been approved by the Environment Agency, Highways England and local authorities with great success.  
IBA Aggregate can be used in two major applications.  Unbound, it can be used for bulk fill and sub-bases.  When bound, it is ideal for road paving and construction blocks.  

By using IBA Aggregate, the benefits are: 

  • Helping to save our natural resources
  • Diverting at least 95% residual municipal waste from landfill
  • Generating electricity for the community
  • Reducing carbon footprint by producing a valuable secondary aggregate locally           
  • Pozzolanic (cement-like) properties, enhancing its performance over primary aggregates
  • Less tonnage needed per m3 vs. primary aggregates
  • Avoiding the £2/tonne tax applied on primary aggregates

The IBAA cycle - how the road to waste leads to the waste in roads

Ardula removes waste Incinerator Bottom Ash on a daily basis, and transports it to the FortisIBA facility in Andover. Vehicles are reloaded with processed material, which is then returned to Kent for stockpiling, blending, and resale into the construction aggregate market
