Wood Wool panels and tiles that cannot be refurbished will be ground down and used as ballast and filling material, moisture absorbent sprinkling, a substrate for running tracks, etc. No negative environmental impact arises when wood wool is deposed in nature. On the contrary, it adds a calcium supplement. When CO2 from the air binds to the cement particles, calcium is formed (i.e. carbonation). Acoustic Pulp panels that cannot be refurbished will be ground down into smaller pieces and then returned in a circular process as raw material for new production. This process is 100 % circular without any material waste. Recycled PET dividers that cannot be refurbished will be ground down to fibres for reuse in other PET products, giving them a second life.
