Melissa shoes are made from Melflex, a PVC compound that is 100% recyclable, vegan, and cruelty-free
Melissa shoes are made from Melflex, a PVC compound that is recyclable, vegan, and cruelty-free. Melflex is a durable plastic that can be used for many years and recycled when no longer needed. Melissa, a Brazilian shoe brand, has attracted a cult following among women seeking stylish, comfortable, and eco-friendly shoes. The brand is committed to creating shoes that customers will love for a long time.
Melflex is a proprietary and 100% recyclable PVC plastic developed and patented by Grendene, the parent company of Melissa. It is composed of a mix of virgin, recycled, and bio-based plastic. The simplicity of this mono-material construction sets Melissa apart from the footwear industry, where the complex mix of different components has traditionally been challenging to clean, reuse, disassemble, and recycle. Melflex is also versatile, resilient, and reusable, making it an extremely environmentally friendly alternative to other types of PVC.
However, the opinion on the sustainability of PVC is split. While Melissa claims that its PVC is eco-friendly, there is little official information or public evidence to support this claim. Environmental groups like Greenpeace argue that PVC is the most environmentally damaging of all plastics, releasing toxic chlorine-based chemicals at every stage of its production, use, and disposal, resulting in health problems.
Despite the controversy surrounding PVC, Melissa demonstrates a commitment to sustainability and positive production practices. Every piece of plastic leftover from shoe creation is recycled, with an average of 30% of each shoe made from this recycled factory waste. In 2022, 90% of their total waste was reincorporated into production, and they aim to become a zero-waste business. Additionally, Melissa treats and reuses 100% of its wastewater and powers its factories with 100% renewable energy.
Overall, while the eco-friendliness of Melissa shoes' product lifecycle is debated, the brand makes efforts towards sustainability and creates long-lasting products that reduce the need for frequent shoe purchases.
