Pistachio shell, from waste to energy to make our pants

Cáscara de pistacho, de residuo a energía para fabricar nuestros pantalones

Sustainable energy for a greener future

As you know, we are committed to sustainability at all stages of our production, including the energy we use to make our jeans. In honor of World Pistachio Day , we want to highlight the fundamental role that biomass plays in our quest for a greener, more sustainable future. Biomass, derived from organic waste such as pistachio shells, is a renewable and sustainable energy source that allows us to power our factory responsibly and reduce our environmental footprint .

Biomass: a sustainable energy source

Biomass is a renewable energy source that comes from biological materials or organic waste, such as pistachio shells. At Captain Denim we use biomass as a sustainable alternative to fossil fuels to run our factory. By using organic waste as a source of energy, we contribute to reducing dependence on non-renewable resources and mitigating the environmental impact associated with energy production.

Biomass and its Environmental Impact

The use of biomass as an energy source has numerous environmental benefits. First, biomass is considered carbon neutral , meaning it does not contribute to the net increase of CO2 in the atmosphere. This is because the CO2 released during the combustion of biomass is equivalent to the CO2 absorbed by plants during their growth. Additionally, by using organic waste as fuel, we contribute to reducing the amount of waste that ends up in landfills, which helps mitigate the problem of waste and pollution.

The Importance of Biomass in Captain Denim

We recognize the importance of adopting sustainable practices in our production. The use of biomass as an energy source allows us to reduce our environmental footprint and move towards a greener and more sustainable future. Furthermore, by using pistachio shells as one of our main biomass resources, we also contribute to the use of agricultural surpluses and support the local economy. By harnessing this waste, we close the circle of circularity, promoting a more holistic and sustainable approach in our supply chain.


Along with biomass, nebulization, ozone and laser finishing are included in the umbrella of our own Greensight technology with which we manage to save up to 90% of water in our production process. Learn more details about Greensight by clicking here .

In summary, biomass is a renewable and sustainable energy source that plays a fundamental role in the search for a greener and more sustainable future at Captain Denim. We are committed to continuing to use biomass and other sustainable energy sources in our operations to reduce our environmental footprint and promote responsible business practices.
