Regarding sustainability the most fundamental criterium for ADUU MAL is creating transparency in the supply chain. This to realistically face matters for improvement and effectively explore more sustainable solutions. It's an ongoing process,

Depending on the type of leathers, horse hairs and yarns produced for the customer, targets are set and refined. 

For our horse hair and spinning factory we are in the process of getting certified ISO 45001.

In tanning we cooperate only with third parties that are certified on health, safety, and preferable have specific ambitions with respect of sustainability.


We obtain our raw materials from the source and can track them back to the herders families. The processing of the hides and hairs are all done in accordance with recipes developed with and known to us.


We only process our hides and hairs with products registered by REACH in accordance to EUROPEAN regulations standards for health and safety..

Water for life

Our leathers are tanned and hairs washed based on technology that allow a reduction in the use of water at the first tanning stage and float recycling.

Better reduce the use of salt

Salt is being used for the conservation of the hides. It's a point of attention to be able in future to manage other means of conservation of the hides. In our process we do not need any pickling of the hides and can likewise already reduce the use of salt.

Biodegradable / Renewable resourches / waste

Biodegradable Y/N ?

The purpose of tanning leathers is to stop the process of decay. Therefor it's in general a large contradiction to speak of biodegradable leathers. At various stages in the process decisions can be made that effect degradability more or less. And will potentially leave less or more toxic residues or non at all. And than also still it's biodegradability depends on the specific environment of the waste left behind.

A product being nog bio-degradable isn't necessarily in contradiction with 'nature'. Not all bio-based products are biodegradable. For instance 'hairs' do not degrade easily.

Renewable resources Y/N ?

In our production we prefer another focus and to use products that come from renewable resources.  We also avoid products which can in specific circumstance turn toxic or hazardous at it's end of live (when burned or dumped). Our leathers are wet-whites, metal free tanned and contain no free-aldehydes. The horse hairs are washed with non-hazardous soaps.

Waste recycling Y/N

With our customers we discuss options for the use of waste cuttings and left overs of leathers and or return of used leathers in production when a practical program for this is at hand.

Free roaming animals / Grass fed / Organic

In general the certification of hides as 'organic' of 'grass-fed'  is a relative new development even in Europe as it only follows upon the certification of meat. In the Mongolian environment one can be sure animals live free - range with more than enough space to move. This also complicates standard certification procedure which connect approval to a specific part of grassland to be certified. 

To develop a standard is however also in Mongolia desired. Specially in areas facing problems with over-grazing by cashmere goats and or areas adjacent to agricultural lands. 

Therefor ADUU MAL is solemnly working with cooperatives interested in making a transition to being certified in accordance with 'Grass-fed' standards. Education on the matter is also part of the training we give in raw -material management.
