Aggregate Industries, UK: EnviroBlock©: replacing quarried aggregates in building materials

In the UK, the marketplace is placing increasing value on the use and reuse of construction materials. The recovery of materials following demolition can be problematic, in particular through the contamination of concrete materials from steel and other materials.

In Masterblock, one of Aggregate Industries UK's businesses, the demand for building blocks using high percentages of reclaimed materials is growing. Four years ago, EnviroBlock© was developed. The product contains 100% recycled aggregate or 100% secondary aggregate derived from the china clay industry.

This material is replacing quarried aggregates in building materials that set a high standard in terms of their sustainability credentials. EnviroBlock has been externally evaluated by the Building Research Establishment (BRE) and has an "A"-rated Environmental Profile.
