Ecoblend® Sustainable Aggregates from Day Group
Ecoblend® is a Day Group brand of sustainable construction products, developed to combine technical performance with responsible material use.
What is IBAA?
Incinerator Bottom Ash Aggregate (IBAA) is a manufactured aggregate produced from the non‑hazardous ash generated by the energy‑from‑waste process.
IBAA supports sustainable construction by reducing landfill, lowering reliance on quarried materials, and contributing to a more circular construction economy.
Day Group has played a leading role in the development, processing, and assurance of IBAA, helping to establish it as a credible, high‑performing construction material.
As a manufactured aggregate, when correctly produced, IBAA offers predictable performance characteristics and consistency, making it a practical and responsible approach to selecting materials.
How is IBAA Manufactured?
The manufacture of IBAA follows a controlled, multi‑stage process designed to ensure quality, safety, and performance.
Day Group Processing Capability and Investment
Day Group has made sustained investment in IBAA processing capability, developing purpose‑designed plant operations to support consistent quality, increased capacity, and reliable supply.
This includes investment in advanced processing technology, materials handling, and quality control systems.
The opening of the Wellingborough in 2024 alongside operations at Avonmouth, Brentford, and Greenwich, marks a significant milestone in Day Group’s infrastructure investment, strengthening processing capability and supporting regional supply.
Compliance with Highway Specifications
Ecoblend® is manufactured to meet the same requirements as primary aggregates for:

6F5
Benefits of Recycled and Manufactured Aggregates
When produced to recognised standards, recycled and manufactured aggregates deliver reliable performance while supporting sustainability targets and responsible procurement policies.
Their environmental and operational benefits, including:
- Reduced demand for primary aggregate extraction
- More cost-effective than primary alternatives
- Diversion of material from landfill
- Lower embodied carbon associated with raw material sourcing
- Effective use of materials already within the resource cycle
Volumetric Efficiency: Less Tonnage,
Fewer Lorry Movements
A key advantage of Ecoblend products is their volumetric efficiency. Engineered to perform by volume rather than weight, less tonnage is required to achieve the same engineering outcome compared with traditional primary aggregates. This results in:
Less material required
Fewer vehicle movements
Lower transport related emissions
Improved site logistics and programme efficiency
Standards, Quality, and Assurance
Out IBAA is produced within robust quality and environmental management systems. Comprehensive testing, certification, and compliance processes underpin its manufacture, providing confidence in technical performance, consistency of supply, and regulatory compliance.
Clear specifications, traceability, and ongoing assurance ensure our IBAA products are suitable for use where safety, reliability, and defined standards are essential.
Industry leadership
Day Group is a leading member of both the Manufacturers of Incinerator Bottom Ash Aggregate Association (MIBAAA) and the Mineral Products Association (MPA). Through active participation, we contribute to the development of standards, guidance, and best practice for IBAA and the wider use of recycled and manufactured aggregates in construction.
