How to Achieve Material Savings with Manufactured and Recycled Aggregates
In a world striving for greener, more sustainable construction, the principles of “reduce, reuse, recycle” isn’t just environmental alliteration, it’s a blueprint for a circular economy. At the heart of this shift lies the innovative use of manufactured, and recycled aggregates, like Ecoblend®, which deliver genuine material savings without compromising performance.
Circular Economy in Action
The circular economy centres on keeping materials in use for as long as possible – recovering, regenerating, and redeploying what would otherwise be waste. In construction, this means repurposing secondary materials (such as construction demolition waste and premium grade IBAA) into vital infrastructure components. Not only does this reduce dependency on quarried aggregates, but it also diverts significant volumes of waste from landfill, helping to close the loop.
IBAA, a by-product of energy-from-waste processes, embodies these principles perfectly. Once processed, graded, and blended, it becomes a valuable option for sub-base and capping materials for the built environment, especially roads, pavements, platforms, and foundations. Through advanced manufacturing and blending techniques, Ecoblend delivers exceptional performance using fewer materials, prompting the question: how is this possible?

Why You Need Less to Do More
Here’s where the real value lies: volumetric efficiency. For example, unlike denser primary stone, Ecoblend CA’s IBAA element has a compacted bulk density of 1.83 t/m³, compared to 2.3–2.4 t/m³ for primary materials. This means that per cubic metre, you typically need 15-20% less material by weight to achieve the same coverage. The reason? IBAA’s naturally vesicular structure – a result of combustion – makes it slightly lighter without compromising geotechnical performance or structural integrity.
So, a 100 m³ sub-base might require 220 tonnes of primary stone – but only around 185 tonnes of Ecoblend (depending on product selected). That’s fewer tonnes to purchase, handle, and haul, meaning reduced transport costs and fewer lorry movements, a clear logistical and carbon-saving benefit.
Calculating with Confidence
Ecoblend’s material calculator demystifies the process, letting you enter your required volume and instantly receive accurate quantity estimates based on the material’s specific density. This tool ensures you can optimise orders, prevent overbuying, and deliver more sustainable outcomes.
Ecoblend’s online material calculator empowers contractors and specifiers to realise these savings with confidence and precision.
In short, using blended IBAA and recycled aggregates supported by tools like the Ecoblend calculator, doesn’t just make environmental sense. Less material really is more.
