At Tintoremus, we continue to strive for maximum transparency in our methodology. That's why we've partnered with BCome, a global sustainability management platform, to meticulously map our supply chain and gain insight and transparency into the impact of our processes.

Crop impact

The analysis carried out by cultivating one hectare of Persicaria Tinctoria for one year, 2024, shows the following benefits compared to the production of bell pepper (the main crop in the area):

88%

REDUCES WATER SHORTAGES

98%

REDUCES THE GLOBAL WARMING FOOTPRINT

99%

REDUCES RESOURCE DEPLETION

While one of the most popular crops in Extremadura, bell pepper, requires large amounts of water and contributes to soil depletion, the cultivation of Persicaria tinctoria stands out for its lower environmental impact and its ability to preserve the soil over the long term in a region where water is a limited resource.

Extraction impact

The analysis carried out on the extraction method during the year 2024 shows the following benefits compared to an equivalent dye on the market, with the same properties and functionality:

66%

REDUCES WATER USE

88%

REDUCES EMISSIONS

79%

REDUCES RESOURCE DEPLETION

14%

CONTRIBUTES TO THE PRESERVATION OF AQUATIC ECOSYSTEMS BY REDUCING THE IMPACT ON EUTROPHICATION

BCome Methodology

These data are based on an analysis of the environmental impact of Tintoremus indigo dye cultivation and production during 2024 in Extremadura, Spain. The Tintoremus production system was analyzed by collecting primary data at each stage: cultivation, fermentation, alkalization, oxygenation, filtration, and drying. Using the Life Cycle Assessment (LCA) methodology (ISO 14040 and 14044), various production systems were compared:

  • First, the cultivation system of Tintoremus Persicaria tinctoria is compared with conventional crops (such as pepper - impact calculated using ecoinvent 3.10, APOS method) in Extremadura (functional unit = 1 ha crop for 1 year in Spain).
  • The extraction of Tintoremus dye is also compared with alternative (natural) dyes. In this case, the functional unit is the "gate-to-gate" extraction (without raw materials input) of 1 kg of dye. The alternative natural indigo dye is modeled with primary data obtained from the competing company that produces it.
  • Finally, the environmental impact of conventional (synthetic) dye production methods is assessed. In this case, the functional unit is the "cradle-to-gate" production of 1 kg of dye. The synthetic dye is modeled based on the stoichiometry of the reaction of indigo production with chemicals and background data from ecoinvent 3.10, APOS method.

The environmental indicators chosen for the analysis are global warming (IPCC 2021), water scarcity (AWARE), eutrophication (CML v4.8 2016), and abiotic resource depletion (CML v4.8 2016).
