How are Melissas made?
Grendene is on a sustainability journey where every step taken seeks to promote more positive production practices.
Our shoes are manufactured mindfully: we balance our goal to give our customers shoes they love with the care we must show for our shared planet and its precious resources.
We treat 100% of our wastewater.
Thanks to the installation of water treatment stations in all our factories, we can also reuse the majority of our wastewater (86% in 2022) in our processes.
Fortunately, the water footprint of plastic is relatively low compared to other materials often used in the wider footwear industry (like leather or cotton). We track our water consumption carefully and know that 30% is used in the production of our shoes.
This means the majority is used to support the activities of our people, e.g. drinking fountains and restrooms.
Our factories are powered by renewable energy.
Melissa’s have been made using 100% renewable energy since 2018. Through the purchase of renewable energy certificates covering our electricity use, we have helped to reduce the carbon emissions of our manufacturing processes.
We are investing in greener infrastructure at our factories, too. For example, we have installed a Solar Power Plant at our factory in Sobral. Furthermore, in 2023, we will install over 4,000 panels at the new Crato factory, which will account for 34% of self-generated energy. The panels will also contribute to the thermal comfort of our employees.
By adding these solar panels to the roof, 2.5% of the average annual energy used to create our shoes is now powered directly by the Brazilian sunshine.
On our way to zero-waste excellence.
As part of our commitment to eco-friendly production, every piece of plastic left over from the creation of the shoes returns to the beginning of the process so that, on average, 30% of each shoe is made from this recycled factory waste.
But we don’t stop there: in 2022, 90% of our total waste was reincorporated in the production (so did not go to a landfill), and we are committed to becoming a zero-waste business where all our trash is treasured.
By example, we reuse leftover food and other organic materials to generate cooking gas and fertilizer.
