Kvadrat Really materials are produced from recycled textiles collected from production waste, industrial laundries, the fashion industry and Kvadrat’s production and supply chain. The textiles are sorted by colour and re-milled in Denmark. Subsequently, the fibres are either blended into standard products or used to create a nonwoven base for Kvadrat Really materials, such as acoustic solutions and panels for furniture and interiors. The compressed panels are made with 9% bio-based polypropylene (bio-PP) and 17% bio-based polyethylene (bio-PE) binder. According to the company's environmental product declaration (EPD), Kvadrat Really has a carbon footprint of 0.95 kgCO2/kg in the production phase (excluding use and end of life). The standard product is 10 mm thick and 1100 x 3000 mm, weighing 29 kg. This gives a density of around 88 kg/m3. Image Kvadrat.
