Eco-friendly concrete - what does that mean?

Concrete has a high carbon footprint due to the production process of its hydraulic binder – cement. Various solutions are available to reduce the amount of cement and make the concrete more environmentally friendly. However, concrete can contain up to 80% of sand and that causes another not as widely known problem. Due to a steady upward trend in global sand demand, mining activities and in particular dredging operations extract far more sand than can naturally be replenished. On the one hand, this causes river bank instability and damage to houses and infrastructure and injuries to inhabitants. On the other hand, fish populations dwindle due to a loss of breeding grounds and fishermen lose their livelihood. Further downstream the missing deposits of sediments mean an intrusion of salt water into the river delta and destruction of fertile farmland. Not to mention erosion of beaches which have to be repaired at enormous costs.

As a social impact business, it is our mission to not only reduce harm to vulnerable populations and our planet but to actively improve the way we do things. And that starts with sourcing our raw materials.

Replacing cement with more sustainable options is a great start and alternatives for sand need to be taken into consideration as well. Until recently, low quality sand did not have many applications. Our patent-pending technology makes it possible to have an engineered sand product that contains low quality sand, reclaimed waste material, and renewable additives that together act like regular ‘angular’ construction sand. 

A combination of all of this creates a truly eco-friendly concrete – from the source.
