GGBS EPD provides clarity on environmental performance
Environment Product Declaration for Heidelberg Materials UK’s evoBuild low-carbon ggbs
HEIDELBERG Materials UK have a new Environmental Product Declaration (EPD) for their evoBuild low-carbon ggbs (ground granulated blast-furnace slag) cement replacement product.
The EPD, published by leading EPD programme operator EPD-Norge, provides clarity on the product’s environmental performance and has been produced in accordance with EN 15804, a European standard for producing EPDs for construction products.
evoBuild low-carbon ggbs is a by-product of the steel manufacturing process. Previously known as Regen GGBS, it is an important supplementary cementitious material (SCM) and is a tried and tested option for reducing the CO2 emissions associated with concrete.
Heidelberg Materials UK say they have a safe and secure volume of ggbs for supply across the UK for many years.
‘evoBuild low-carbon GGBS is the best SCM available for delivering carbon reduction,’ explained Nina Cardinal, technical strategy director at Heidelberg Materials UK. ‘It is readily available from Heidelberg Materials in the UK and is proven to also provide enhanced concrete performance through improved durability.’
evoBuild is Heidelberg Materials’ global brand for low-carbon and circular products and all evoBuild products have clear sustainability credentials. Low-carbon products must provide a CO2 reduction of at least 30% compared with global reference values from the Global Cement and Concrete Association (GCCA).*
Circular products in the evoBuild range must either contain a minimum 30% recycled content or use at least 30% less material. These evoBuild standards will apply to products in cement, ready-mixed concrete, aggregates, and asphalt. All UK sustainable products will be integrated into the evoBuild portfolio over the next few years.
*The evoBuild reference value is at least 30% CO2 reduction vs the global reference values from the Global Cement and Concrete Association (GCCA) for CEM I from 2020, which translates to ≤552kg CO2/tonne cementitious material and ≤ 5.5kg CO2/m3/MPa for ready-mixed concrete.
