Exploring Incinerator Bottom Ash IBA Aggregates

Building supplier partnerships

Managing and working closely with our supplier network, MCM’s Dani La Porta and Isaac Francis visited an IBA Processing Facility in Oxfordshire in November 2025.

An ideal opportunity to meet up, they could see first hand the work that our suppliers do, diverting tonnes of waste from landfill, recycling, processing, providing us with IBA aggregate for our construction customers.

Approved by the Environment Agency, Highways England and local authorities across the UK, MCM source IBA aggregates with a greater bulk density than primary – reducing quantities needed for earthworks and road construction.

IBA Aggregates (IBAA) in live projects

One of our recent projects involved the supply of IBAA to Milton Keynes, where the client needed to meet commitments to sustainable construction. MCM sourced and delivered IBAA in 1A fill and Type 1 size to be used for subbase preparations for road and path construction.

To find out more about IBAA and other recycled aggregates from MCM, visit our Construction Aggregates pages. Our commitment to Sustainability in Construction is outlined on our Environmental pages.
