OUR AMAZING GLASS ! Garments are just one example of materials that could decrease its environmental impact . Another important material is glass . Glass affects the environment in several ways and historically , many substances have been used that are harmful to the environment . Orrefors Kosta Boda has conducted active environmental work for a long time and has been world leading in its ambition to create crystal glass without lead and arsenic . This glass is sometimes referred to as “ eco-crystal ”, but in Kosta Glassworks it is simply the material used for the entire glass manufacture in Kosta . The quality and environmental management system in the production unit in Kosta is certified according to ISO standards and waste heat from the glassworks is delivered to the district heating network in Kosta . Also , in recent years several products made from recycled waste glass from their own production have been developed .
EXP 4.0 MERINO REWOOLTION Wool is a fantastic material and more sustainable in itself than most other textile fibres . It is a 100 % biodegradable and renewable fibre , valued for its natural water- and soil repellence . Unfortunately , the processing of wool includes steps with negative environmental impact . The process of one ton of wool treatment requires approximately 0.5 ton of chlorine , several other industrial chemicals and huge amounts of water .
EXP 4.0 is a modern technology of wool that requires fewer chemicals and uses up to 50 % less water than older treatments .
EXP 4.0 is the first wool treatment that meets stringent requirements of eco-labels such as GOTS . Our brand Seger obviously chose to knit its Sense and EveryDay socks in EXP 4.0 treated wool .
