New EPDs document reduced carbon footprint from Troldtekt acoustic panels
EPD Denmark has published new environmental product declarations (EPDs) for Troldtekt acoustic panels. The carbon footprint of the panels has dropped by between 12 and 20 per cent since the last EPDs were issued in 2021. Optimisations in cement production in particular have contributed to the reduction.
Developers and consultants can now count on an even lower carbon footprint than before when they choose to use Troldtekt acoustic panels in their building projects. The brand new environmental product declarations (EPDs) from August 2025 show that the footprint from the acoustic panels has reduced since the last EPDs were issued in 2021.
- The carbon footprint is now 12 per cent lower for Troldtekt in natural wood, which is based on white cement
- The carbon footprint is 20 per cent lower for Troldtekt based on the FUTURECEM™ cement type.
"We are pleased that we have sucessfully continued to reduce the carbon footprint in recent years. The carbon footprint reduction, together with material health, is crucial when we talk about sustainability efforts in building projects. This is a focus we recognise from several countries, especially in Denmark, where legislative requirements relating to the carbon footprint of newbuilds have been tightened significantly," says Tina Snedker Kristensen, Head of Sustainability & Communications at Troldtekt A/S.
"Our work is far from over. According to the plan, by the end of 2025, we will launch acoustic panels with an even smaller carbon footprint," she adds.
Includes stages from A to D
The new EPDs have been drawn up in accordance with the EN 15804+A2 standard and include the following product stages:
In the EPDs, the carbon footprint is expressed as the Global Warming Potential (GWP).
Reduction from cement
Troldtekt acoustic panels consist of wood and cement and, at the Troldtekt factory in Troldhede, 98.3 per cent of energy used in production originates from renewable sources. Since 2021, the production of cement, which Troldtekt purchases from external parties, has played a large part in this carbon reduction. There have been reductions for both white cement, which is included in the panels in natural wood and for FUTURECEM, which is included in all other panels.
In addition to the lower carbon footprint, the EPDs have also been improved in several areas and we have included more stages. Waste at the building site is now included in the footprint and the conditions for product transport from Troldtekt's factory to the building site have also been adjusted. It is now possible to select carbon figures for three different end-of-life scenarios when the panels reach the end-of-life stage: Incineration, landfill or recycling of crushed panels in the biological cycle.
"Our production takes place in Denmark, where incineration has so far been the official end-of-life scenario. However, in other markets such as Germany, landfill is the official scenario and we therefore provide figures for both scenarios so that customers can make more direct comparisons with other EPDs," explains Tina Snedker Kristensen.
"Nevertheless, the best scenario is the third one in the EPD, in which panels that have reached end-of-life can be crushed and returned to the biological cycle as animal bedding, for example. This is one of the many return models we are working on to ensure that Troldtekt panels have one or more additional life cycles in buildings," she adds.
Independent verifiers
The new EPDs have been published by EPD Denmark.
The life cycle analyses themselves were prepared by Stefan E. Danielsson, who is an independent verifier affiliated with EPD Denmark. One of EPD Denmark's other independent verifiers, Mirko Miseljic, carried out the third-party verification of the EPDs.
