Absorbs CO2 during use
Troldtekt only uses cement from Aalborg Portland, which extracts the raw materials from the Danish underground with minimal environmental impact.
When we produce the acoustic panels, the cement in the cement-bonded wood wool starts to absorb CO2 gradually as it sets. The cement layer that surrounds the wood wool in a Troldtekt acoustic panel is very thin and therefore has a large surface area. Consequently, all the cement can more easily carbonise – i.e. bind CO2 – during the lifespan of the panel. In fact, a Troldtekt acoustic panel is able to naturally absorb and store more CO2 than solid concrete.
Towards an even lower carbon footprint
The cement accounts for almost the entire carbon footprint of a Troldtekt acoustic panel, and our ambition is to reduce this footprint even further. This can be achieved both by reducing CO2 emissions from cement production and – in the longer term – by finding an even greener alternative to completely replace cement.
Aalborg Portland is collaborating with the Danish government on realising extremely ambitious goals for reducing its CO2 emissions. Specifically, the company has committed to reducing emissions by 600,000 tonnes in order to support Denmark’s goal of reducing GHG emissions by 70 per cent by 2050. The sub-goal is a 30 per cent reduction by 2030.
In addition to launching greener cement products such as FUTURECEM™, Aalborg aims to achieve its goals by working with energy-efficiency improvements, by phasing out fossil fuels, through carbon capture, through the increased use of alternative or carbon-neutral fuels and by supplying carbon-neutral district heating to over 75,000 households.
