  1. Sustainable cotton

    Cotton is a natural fibre, but growing conventional cotton is very chemical-intensive. These chemicals have a significant impact on the earth’s air, water, soil, and the health of people in cotton-growing areas.

    • A. Organic cotton

      Organic cotton production maintains soil fertility, reduces the use of toxic and persistent pesticides and fertilizers, and builds biologically diverse agriculture. Third-party certification organisations verify that organic producers use only methods and materials allowed in organic production, and some require that cotton yarn production is environmentally and socially responsible.

    • B. BCI cotton

      The Better Cotton Initiative (BCI) trains farmers to use water efficiently, care for soil health and natural habitats, reduce the use of the most harmful chemicals and respect workers’ rights and wellbeing.

      Better Cotton is not physically traceable to end products. However, BCI Farmers benefit from the demand for Better Cotton in equivalent volumes to those we source through a Mass Balance system. This means for every kilo of BCI cotton we buy, an extra kilo of BCI cotton is grown, but does not necessarily end up in our products.

  2. Recycled fibres

    Using recycled fibres is one of the best ways to reduce the environmental impact of the fashion industry. Switching from virgin fibres reduces the impacts of raw material production and diverts recycled material from landfill or incineration.


      Recycled cotton is made using post-industrial and post-consumer cotton waste and is a more sustainable alternative to both conventional and organic cotton . It has the potential to help reduce water and energy consumption as well as help keep cotton clothes out of landfill.


      Recycled polyester can be made from pre-consumer or post-consumer waste, but the feedstock is mainly recycled PET plastic bottles. It gives a second life to non-biodegradable material that could otherwise end up in landfill or the ocean. It also has a lower carbon footprint because much of the carbon impact of virgin polyester is related to the extraction of crude oil.


      Recycled nylon (polyamide) has a lower carbon footprint than virgin nylon and uses very few chemicals. This also has the benefit of using difficult to dispose of waste such as discarded fishing nets or carpet.


    Most man-made cellulosic fibres are wood-based viscose or lyocell.

    Viscose produced through several chemical processes which transform the wood into a cellulose wood pulp. Conventional viscose uses large amounts of energy and chemicals in the production process and has been linked to deforestation of ancient forests. Lyocell is a second-generation viscose manufactured in a closed-loop chemical process, using a non-toxic solvent to extract the wood pulp which is almost entirely re-claimed, filtered and re-used.

    All the sustainable viscose fibres below are made by the Austrian company Lenzing. While we hope more sustainable viscose options will become available soon, Lenzing is currently the only viable manufacturer for Warehouse.

    • A. Lenzing TENCEL®

      TENCEL’s™ production process is comparable to generic lyocell in terms of water and energy usage. However, the trees used for the production are rain-fed, and no synthetic pesticides and fertilisers are used. The fibre also carries the OEKO-TEX® Standard 100 and EU Ecolabel certifications which guarantee the environmental performance of the production process.


      The wood used for the production of LENZING™ ECOVERO™ fibres is from semi-natural forests or plantations that are FSC® or PEFC™ certified. These types of forests and plantations have only a minimal negative impact on the natural water supply. Additionally, Lenzing’s chemical process has a considerably lower environmental footprint than other viscose fibres.


      TENCEL™ REFIBRA™ is a branded lyocell fibre produced with a new recycling technology using a mix of pre-consumer cotton scraps from the textile industry and wood as feedstock. The fibre is produced in Lenzing’s closed-loop chemical process.
