In three years, Troldtekt has reduced its carbon footprint per square metre of acoustic panels produced by 6.9 per cent. This is shown by data in Troldtekt’s CSR report for 2023. The reduction has occurred in scope 3, which mainly covers cement from Aalborg Portland. Part of the explanation is due to the cement type FUTURECEMTM.
Cement provides the well-known Troldtekt® acoustic panels with their robustness, fire retardant properties and
extensive durability. But the cement from Aalborg Portland also accounts for virtually the entire carbon footprint
of the panels. In 2023, Troldtekt reduced its carbon footprint per square metre of acoustic panel produced by 4.3
per cent.
Over three years – from 2020 to 2023 – the reduction has been 6.9 per cent.
The new CO2 figures are included in Troldtekt’s CSR report for 2023. It shows that 99 per cent of the carbon
footprint in 2023 came from the so-called scope 3, which primarily covers the purchase of cement. At Troldtekt’s
own factory (scope 1 and 2), 94.5 per cent of energy consumption in 2023 came from renewable sources in the
form of biofuel and wind power. This figure was slightly lower than in previous years due to a period of
maintenance on the biomass boiler.
"Reducing CO2 is one of the most important focus areas in construction. Over a number of years, we have
approached 100 per cent renewable energy in our own factory, and now we have also started reductions for
scope 3, which is more difficult. Our ambition is to continue to reduce significantly as we roll out new types of
cement in our production," says Tina Snedker Kristensen, Head of Sustainability and Communications at
Troldtekt A/S.
FUTURECEM makes a difference
In 2023
Troldtekt doubled the share of acoustic panels produced based on the cement type FUTURECEM.
Together with other reductions at Aalborg Portland, this is a significant part of the explanation for the decrease
in the carbon footprint. FUTURECEM utilises the synergies between calcined clay and lime filler, making it
possible to replace a large part of the burnt clinker in the cement.
Over the entire product life cycle, the carbon footprint of Troldtekt acoustic panels based on FUTURECEM is:
- 26 per cent lower than that of Troldtekt panels based on grey cement
- 38 per cent lower than that of Troldtekt panels based on white cement.
"In 2023, acoustic panels based on FUTURECEM accounted for approximately twice as much of our production
as in 2022. This meant that the amount of FUTURECEM was almost on a par with the amount of traditional grey
cement. The share of FUTURECEM will continue to increase significantly when we completely phase out the
panels based on traditional grey cement from 2024," explains Kristensen.
She adds that Troldtekt is also gradually starting to replace white cement with FUTURECEM in the many panels,
which are painted in white and other light colours.
Gold certification, energy savings and launch of ISO work
Our carbon footprint reduction and the doubling of acoustic panels based on FUTURECEM are two of the
highlights in the CSR report for 2023. Here are three more:
> The range of Troldtekt acoustic solutions in natural wood and the standard colours grey, white, clay and
black once again achieved gold after re-certification according to Cradle to Cradle Certified® in
autumn 2023. In three out of five categories, Troldtekt is certified according to the concept's version 4.0,
where the requirements are stricter. These are Material Health, Renewable Energy and Carbon
Management and Water & Soil Stewardship. In Material Reutilization and Social Fairness, Troldtekt will
be certified according to version 4.0 in 2025.
> Troldtekt has installed a heat exchanger that utilises waste heat from the production drying process. The
pilot project has resulted in a 30 per cent reduction in energy consumption in the sections of the
drying oven where the trial was conducted. Our ambition is now to install heat exchangers on more
oven sections in production.
> In 2023, Troldtekt started working towards achieving two ISO certifications by 2024: ISO 9001
(quality management) and ISO 45001 (occupational health and safety management). They systemise all
core processes and build a solid foundation for future improvements.
