Sustainability criteria for products

interloom is an open B2B marketplace for the most ecologically and socially sustainable materials and services for the fashion and textile industry available on the market at the moment. The realization of very innovative and sustainable materials is often only facilitated through the collective orders via interloom.


Sustainability includes for us the following five dimensions:

  1. ecoLOGICAL (ecology)
  2. fa!r (fairness)
  3. valuable (economic viability)
  4. innoxious (health)
  5. aesthetics (design)

Our vision

If we should express our vision in a very simple way, we would say: May all be happy!
From the farmers to the workers to the consumers to future generations.

On product level this means for us:

  • only re(sponsible)sources from natural, renewable raw materials or recycled materials (incl. colours etc.)
  • fair working conditions incl. fair wages and safe working environments at all levels of the whole product life-cycle
  • emissions (CO2, water etc.) neutral or as low as possible and below the carrying capacity or regenerative capability of the targeted medium
  • products without any substances dangerous for human health
  • products that are biodegradable or may be re-utilized in technical systems

Realistic approach

However, there is neither a single product nor a single standard in place which already fulfills all these requirements. So we try to find the most sustainable products available and we work together with our suppliers to continuously improve the sustainability performance of their products.

Minimum product criteria

As we don`t want to add to the labelling muddle by creating new standards, we use the most sustainable existing standards and certificates as minimum criteria for our products. Obviously there are different standards for different product categories, so please check out our product category specific standards. Please see our positive list with our minimum criteria for fabrics.

Inclusive approach

As our aim is to support as many suppliers as possible to switch to a more sustainable production, we especially support in-conversion-projects. While some of these projects are already certified, e.g. as in-conversion organic cotton, others are not yet certified. We also organize fabricmobs to provide companies an incentive to produce more sustainably.

Standards, controlling and trust

As we know that many small suppliers or suppliers-in-conversion cannot or not yet afford their own certification or very consciously decide to not get certified out of different reasons [e.g. because they feel that they are to low], we also accept uncertified products in exceptional cases. However, we demand a transparent and reliable proof that the products are produced according to highest social, ecological and health-related standards. As base for these criteria the above-mentioned product specific minimum criteria should be used as a reference point.

Sustainability as a process

As we consider sustainability as a process and as hopefully more and more sustainable products are produced, our minimum requirements will rise every year. Because only the most sustainable products are sustainable enough for us. While for example organic cotton fabrics are a great step towards sustainability in contrast to conventional cotton fabrics and can be found only very rarely on the market, organic cotton fabrics are hopefully rather common in the next years and we can move on to develop even more sustainable products.
