Raw materials

27% of our total CO2 emissions

Pioneering sustainable materials in acoustics.

Whenever we’re looking for new designs, products or materials, nature is always our first source of inspiration.

We strive to create acoustical solutions that not only check the boxes of functionality and design, but that also contribute to creating a better tomorrow for our planet. Nature provides a wellspring of ideas for colours, patterns and shapes. And, when you explore beneath the surface, it holds the key to removing unsustainable ingredients from the equation entirely.

Our criteria for materials:

  • It should be possible to trace the material back to it’s source of origin
  • There should be zero risk of recycled materials containing dangerous content
  • Materials should have a low amount of volatile organic compounds (VOC)
  • It should be possible to recycle and/or reuse the material

The BAUX product range consists of three materials:

BAUX Acoustic Wood Wool

A functional, natural material. BAUX Acoustic Wood Wool is an environmentally friendly, recyclable material made from wood wool, cement and water. Learn more

BAUX Acoustic Pulp

Our 100% bio-based BAUX Acoustic Pulp panel is the first in the world to uncompromisingly combine the performance properties of sound absorption, safety and durability with sustainability and modern aesthetics. Learn more

BAUX Acoustic Felt - Recycled PET

Recycled PET desk dividers and floor stands , made out of recycled PET bottles. Learn more

Cement is the largest source of raw material emissions.

…and that is why BAUX have carefully selected the world’s leading cement supplier in terms of sustainability. An advanced system for carbon dioxide capture has been put in place to ensure that CO2 emissions from the manufacturing limestone heating process are absorbed and re-captured in porous stone materials.

CO2 emissions kg/m2

2.9 kg

2.9 kg CO2 per m2 is the NET CO2 emission from cement.

9.8 kg

The advanced system for Carbon Dioxide Capturing that is in place ensures that inly 9.8 kg CO2 per m2 produced wood wool panel is emitted to produce the cement.

6.9 kg

6.9 of the 9.8 kg is absorbed from the surrounding air in a reactive process called carbonation.


Wood Wool is able to carbonate as much as 70% of the CO2 that was emitted during the manufacturing process.

BAUX Acoustic Wood Wool

BAUX wood fibres are FSC® and PEFCTM certified –– guaranteeing that they can be traced back to responsible forestry operations. The wood is collected from the Swedish forest in the direct surroundings of the factory in order to minimise negative CO2 emissions caused by longer transport distances. The small amount of wood waste that is generated as a result of production is taken care of—80% is used to heat the factory and drying plant. No waste is produced from the timber log.

Raw Materials

  • Wood cement and water.
  • We use locally harvested FSC certified pine and spruce from Swedish forests.
  • We use 100% natural materials with no additives.
  • Our cement provider, Cementa, has been recognised as the world’s most sustainable cement factory. Read more about this under ‘Installation & End of life.’

Installation & End of life

  • Installed Wood Wool products lead to reduced energy consumption due to their heat accumulating performance.
  • All Wood Wool products have a long life and 50 year warranty.
  • Wood Wool captures a significant amount of CO2 from the atmosphere, leading to reduced Co2 emissions.


% of carbon capture: -70%

This means that we have a 70% reduction from the total CO2 that stem from the Wood Wool cement production.

BAUX Acoustic Pulp

The manufacturing process is 100% sustainable and highly technological. The cellulose mix is formed inside a 3D mould with a powerful vacuum method and dried under high pressure. The surface is nano-perforated using an advanced laser technique. All material waste is recycled back into the production process and re-used again. All water used is built into a closed circular system and recycled. The only emission from production is a tiny amount of pure and clean water vapour that is released as the material dries.

CO2 emissions kg/m2

Raw Materials

  • Cellulose, potato starch, wheat bran and plant wax.
  • We use organic and locally harvested cellulose and the wheat bran is a rest product.
  • The wood we derive our cellulose from is FSC
