Accompanying all this evolution, concerns were also growing in terms of service quality, as well as environmental and energy efficiency concerns.

In order to provide our customers and partners with guarantees of quality, in 2013 we started the Oeko-Tex certification for 100% cotton items, which we have maintained ever since.

The services provided are largely intended for articles for the Inditex group, which led us to implement various measures both at an organizational and procedural level so that we can guarantee that the company follows the Inditex group's manual of good practices and that the final article complies with the customer's requirements, namely the creation of a quality laboratory to monitor the various parameters to be analyzed.

With the evolution of the company, the environmental and energy part became a central concern, measures having been taken in terms of the treatment of effluents, being then linked to the Integrated Depollution System of Vale do Ave, through TRATAVE – Treatment of Waste Waters do Ave, SA

What makes us strong in the market is also related to our concern to reduce energy consumption, under the Intensive Energy Consumption Management System (SGCIE), making us more competitive. Another implemented measure refers to a steam generation system powered by biomass, not using fossil fuels.

LTdye proceeded with the industrial licensing with nº 339/2013.
