Ecologic fibre is a textile fibre derived from a post-consumer regeneration cycle, so when clothing is no longer usable in any industry sector, and destined to disposal. Ecologic fibre is in part made of regenerated fibre derived from pre-consumer, specifically from byproducts and waste of textile industrial production, also destined to disposal. These materials are considered 100% ecological because they entirely derive from the recycle of the many types of textile waste, otherwise destined to landfilling, with a high environmental impact on soil and subsoil. Many of these products are made of high percentage of synthetic and artificial fibres, therefore they are not biodegradable, and will persist in soil for centuries, polluting and producing liquids that are extremely dangerous for groundwater.
