SUSTAINABILITY

The purpose behind Econovate®'s development is to radically improve the sustainability of construction materials. This objective has been achieved with the successful reinvention of one of the most fundamental and widely used building materials – the construction block.

What makes Econovate® products different?

Econovate® product EconoBlok® is manufactured from recovered unwanted waste fibre cellulose used as its main aggregate and bound by a sustainable cement, which contain up to 80% of recycled raw materials within its mixture. Because the fibre cellulose diverted from landfill is unsuitable for Paper Mills due to its contamination this waste could be transformed into a product for the construction industry, giving this waste a second chance in a different industry.

The units are manufactured by a bespoke production process where the focus is in its raw material preparation to achieve a standard of material regardless of the source or format of the fibre cellulose to be able to deliver a product with the strength of any current block in the market and the enhanced performance on thermal and acoustics insulation. The second focus of this production is to have a low-tech low-energy consumption process while achieving a product.

Embodied energy for comparison purpose has been calculated on a cradle-to-gate carbon footprint of the wall specification, based on one square metre of wall. The embodied energy figure calculated is 1,890 MJ per cubic metre, with reductions of up to 89% when compared to the same standard lightweight concrete blocks.

The carbon emissions of a wall with traditional products has around 200 kg CO2/m2 emissions per m2 of wall. The figure calculated for EconoBlok® is 88 kg CO2/m2 of wall. When the carbon credit due to sequestration is taken into account, the figure becomes 53 kg CO2/m2 of wall. With the EconoBlok® product there is a 45% to 88% reduction on CO2 emissions per m2 of wall. When the carbon credit due to sequestration is taken into account, the figure becomes -174 kg CO2/m2.

Life Cycle Assessment (LCA) has being conducted by ARUP on the EconoBlok® product. This LCA is based on our current pilot plant setting and already confirms our assumptions. All the calculations have being conducted following An EPD is available on this and the product page.
