I was initially drawn to using concrete as a material in my products because of its versatility, beauty and the preconceptions of its use.
Over the years of working with it I have become increasingly aware of the environmental footprint it has and this has been an uncomfortable companion to my love of it. The basic statistics are that to make a metric tonne of cement produces 950kg of CO2, it also takes 1.3 tonnes of rock to be quarried to make it from.
With this scary stat in mind I began to research and ask questions and was very fortunate to talk to some like minded people from professors studying alternatives to companies developing new ways of manufacture. With this as our inspiration we have been developing, in our workshop, a new concrete.
The environmental impact this has is a tiny fraction by comparison.. The two key points are that the CO2 cost of manufacture has dropped from 950Kg per tonne to 50Kg also, the amount of rock needing to be quarried to make it from has dropped from 1.3 tonnes to zero. This is because the queried material has been replaced with industrial waste.
This is not the end of the journey we hope that in 2022 we will be using carbon negative concrete as a material throughout our workshop. The concept of carbon negative is that there is more carbon within the material than it took to create it, this is awesome, exciting and, unlike some goals set by some headline seekers, is a realistic point to be at.
