Sustainable Solutions

The GDYES molecule is a hybrid biopolymer, a nano-pigment made of minerals and vegetables.

Greendyes ™ is a 100% natural sustainable dyeing method with no precedents in terms of colorfastness and uniformity.
In addition we have improved the dyeing process to optimize consumption, to match the environmental needs:
• NO chemicals
• NO binders
• NO mordants
• Zero heavy metals
• Zero carcinogenic materials
• Zero allergenic materials
• Saving up to 90% of water
• Saving up to 85% of energy
• Saving 70% of dyeing time.

True sustainability is not just about using natural colors. We must be completely sure that the dyeing process is really safe for the environment.

GDYES is a “meta-material” formed from natural raw materials. It is a nano-sized compound. The GDYES bio-polymer has the ability to adhere to the fiber of the fabric, creating a solid coating.
GREENDYES biopolymer has the ability to transmit the color of the associated pigment, but also any other substance that can be “transported”, “stored” or that can adhere to the biopolymer molecule, providing additional functionalities, such as greater homogeneity, self-cleaning or antimicrobial properties.
GREENDYES 5.0 must be considered, therefore, as a MATRIX to which different components or complements can be associated in order to obtain different properties.

GREENDYES is a natural, safe and organic dyeing process. It is a completely new way of dyeing, it has nothing in common with the known natural dyeing techniques, nor with the chemical fabric dyeing techniques.

GREENDYES provides natural solutions for a better world.

The Greendyes process is the result of the search for excellence in terms of efficiency.



The water, time and energy savings values calculated for the Gdyes process:
·Water: 95%
·Energy: 69%
·Time: 71%

Greendyes can be used with natural, synthetic and bio synthetic fibers.
·Natural fibres : cotton, linen, bamboo, hemp…
·Synthetic fibres : recycled polyester.
·Bio-synthetic fibres : lyocell, viscose, PLA, seacell, banana, soya, pinneaple…

Table below shows the colorfastness and shrinkage values for a 2022 production.


We only work with suppliers who match all environmental and social requirements.
All raw materials – including dyes – undergo several tests before being accepted. They must fulfill all these points:
·In the case of coloring materials, provide maximum colorfastness, especially to washing, sunlight and crocking.
·The supplier companies must be environmentally and socially certified.
·The raw materials undergo chemical analysis at 1/1,000,000 in order to verify that there is no cross-contamination from other materials.
·All raw materials are subjected to pH test, granulometry, density and dustiness analysis.
·In the case of dye raw materials, spectrophotometric analysis is done batch to batch.
·Supplier companies must be able to ensure supply throughout the year.
·The cost must be acceptable for the textile industry.

Sustainability has the potential to evolve the world. But it also opens the door to a number of social and ethical risks that industry professionals, researchers and policymakers need to consider

Today, textile industry has the possibility to pass from words to action on several levels, but one thing’s for sure: innovation humans can trust always starts in a sustainability framework. 

The GDYES RESEARCH LAB and the GDYES COLOR FACTORY  are a world-leading multidisciplinary hub to address the scaling of sustainability in the industry, both in environmental as ethical and societal contexts. Working together with our partners and clients, we detect and handle the challenges and create the opportunities.



The GDYES COLOR FACTORY allows the industrialization of the technical innovations developed at the GDYES RESEARCH LAB in the field of textile sustainability.

·Optimizing and improving the dyeing processes (piece dyeing, garment dyeing).
·Helping to decrease carbon footprint and water stewardship.
·Helping to combine the use and reuse of different bio-based materials to achieve full circularity.
·Supporting the creation of a skilled workforce in the facilities of the brands and dyehouses, being a technological and sustainability show-room for transitions towards green manufacturing technologies.
·Helping to standardize the use of  bio-based materials and to adapt characterisation methods and quality controls for bio-based materials in their different formats and applications.

GDYES RESEARCH LAB main areas of research:

  1. natural BIO-pigments, nano-materials and bio-polymers.
  2. ceramic tracker  that can be added to GDYES pigments to have complete traceability of garments.
  3. indigo biopolymer that can be used as a dye and that does not need chemicals or auxiliaries for dyeing (Denim world).
  4. a mineral coating that prevents the loss of color through washing, rubbing or sunlight, and which allows dyeing with all kinds of natural dyes with maximum colorfastness, or also using chemical dyes by covering them completely so that they do not come into contact with the skin.
  5. a natural polymer that can be added to GDYES pigments to give antibacterial, antifungal and anti-odor properties.
  6. a colored geopolymer that can be added in bulk to PLA fibers and PHB (dope dyeing), or that can be used as a coloring agent for common dyeing processes.
  7. a new graphene coating easy to apply and cheap.
