Eight percent of the worlds CO2 emissions are created by concrete manufacturing. On top of that according to Andrew Wheeler (Administrator of the Environmental Protection Agency) the construction industry makes up fourty percent of the planets waste. Consequently making construction sustainable is of very high importance when it comes to concrete. Large format 3D printing with Massivit 3D potentially offers an opportunity to answer all these demands but how can we introduce it?
There are currently two methods being explored on how to combat this predicament. Firstly CarbonCure are trying to create a solution that actually reverses the effect of CO2. They are doing this by introducing recycled CO2 to the concrete so they can reduce its carbon footprint. Secondly there is ETH in Zurich who are trying to reduce the amount of concrete needed in the first place.
If the goal is to reduce the amount of concrete used by thirty – fourty percent then Massivit 3D have already created a solution with their Geoplast formworks moulds.
