Construction of a split-level household recycling re-use centre.
The IBAA (Incinerator Bottom Ash Aggregate) Type 1 subbase was used an as alternative to primary aggregate. The road application was constructed with a 150mm layer of IBAA Type 1 subbase and overlayed with 200mm of asphalt.
IBAA is an extremely cost-effective material when compared to Primary Aggregates and BP UK is working towards a verified Carbon Footprint. There are also advantages logistically when using IBAA due to the low density of the material allowing for fewer vehicle movements as this gives volumetric advantages over primary materials.
The extraction of primary aggregates for construction and transport to construction sites places enormous pressure on the environment. Mineral mining accounts for 2.8% of the global greenhouse gas emissions. The use of manufactured aggregates from IBA prevents landfilling, mining of virgin raw materials and contributes to the circular economy.
