Otrium is committed to the mission that all clothing produced should be worn. While no item or fashion brand can be perfectly 'ethical,' there are many areas where brands can make significant improvements. We want to support fashion companies striving for more responsible fashion and empower consumers to understand what this journey entails.
To offer an objective perspective on the responsibility journey of the brands featured on Otrium, we have collaborated with industry rating specialists from Good On You. This partnership makes it easier for our members to find “Ethically rated” items and support brands working to create a better fashion industry. Most brands on our platform are rated by Good On You, and “Ethically rated” items come from those fashion companies with scores of 3/5 (It's a start), 4/5 (Good) or 5/5 (Great). More information about the ratings can be found on
this page.
In our Ethical Conversations series, we’re exploring the approaches of “Ethically rated” brands featured on Otrium. This time, we chatted with Bert, founder of Mud Jeans, and Lea, a member of their sustainability team.
Tell me, who are you, and what is your role at Mud Jeans?
Bert: My name is Bert van Son, and I founded Mud Jeans. With 30 years of experience, I’ve seen fast fashion's negative impact on the environment. This motivated me to seek a better alternative. In 2012, I introduced the "Lease A Jeans" concept, allowing customers to lease jeans and after use return them for recycling. This initiative reduces waste and promotes a circular economy in fashion, enabling customers to renew their wardrobes more sustainably.
Lea: Hi, I'm Lea, and I studied Sustainability Science, Policy & Society at Maastricht University. My passion for fashion and the well-being of people and the planet led me to a career in sustainable fashion. I am happy to be working at Mud Jeans, where I manage all aspects of corporate responsibility.
Where did it all start for Mud Jeans?
Bert: I've been in the fashion industry for quite some time. I started my career in Taiwan and later in Hong Kong, where I saw the industry transform into something I didn't like—dreadful production processes, poor working conditions, you know the story… Wanting to make a change, I sold my previous company and used the funds to start Mud Jeans. I specifically chose jeans because I realised that to truly do something different, I should focus on an item that is widely worn and has one of the most challenging supply chains.
What sustainability initiatives do Mud Jeans have?
Bert: One of our standout initiatives is our circular economy model. After customers have worn out their jeans, they can return them to us. We then send these pairs to Spain, where factories break the items down into their original raw materials. We reuse this bluish cotton, combined with new organic cotton, to create our jeans. Compared to industry-standard jeans, our production process uses significantly less water—about 25 minutes of showering versus 7.5 hours for a regular pair. Also, transparency is one of our core values: we strongly believe all companies should be truthful about their processes.
Lea: Additionally, we release a sustainability report and conduct a life cycle assessment (LCA) annually to provide detailed insights into our practices. Last year, we introduced an innovative LCA-based approach that evaluates our jeans against a hypothetical product with similar manufacturing processes but without more conscious materials. This method goes beyond comparing our jeans against industry standards and allows us to make more accurate impact assessments. What's more, our approach to sustainability goes beyond environmental concerns and considers social responsibility. We prioritise fair wages and good working conditions throughout our supply chain so that our practices benefit both people and the planet.
How do you involve consumers in sustainability?
Bert: Since 2012, we've encouraged consumers to return their jeans after they’ve worn them out. This concept of retaining ownership of materials and offering jeans on a leasing basis demonstrates our commitment to being different. While we primarily appeal to environmentally conscious consumers—which we call dark green customers—we want to reach a broader audience, as more responsible purchasing benefits everyone.
Lea: We aim to share the Mud Jeans story with all segments and sell our jeans to every consumer. However, effectively communicating our efforts to various audiences remains an ongoing challenge. You don’t want to bore people with the same story, but you can’t keep quiet either.
What sets Mud Jeans apart?
Bert: At Mud Jeans, circularity is at the core of everything we do. We're dedicated to reclaiming our products after use and creating a closed-loop, post-consumer waste denim process named “Denim Reborn”. Also, initiatives like "Lease a Jeans" and maintaining close relationships with our supply chain partners show our commitment.
What is the biggest challenge for you when it comes to sustainability?
Bert: We want to inform people about everything we do while also attracting them with the good fit and nice wash. Balancing this desire to communicate our efforts with the need to appeal to consumers is a challenge. Moreover, being a volume-driven industry, maintaining competitive prices while adhering to better practices remains an ongoing struggle.
Lea: I also see societal challenges, which are increased by rapidly changing consumer trends. People see so much fashion content on TikTok and Instagram that they feel they need to have it all. We’re trying to come up with innovative solutions to keep up with the trends sustainably, but it is rather difficult!
What are the main goals for Mud Jeans?
Bert: Our ultimate goal is to produce jeans made entirely from post-consumer waste. While we've made significant steps and currently incorporate up to 40% recycled materials into our jeans, achieving 100% recycled denim remains our ambition.
What is going well in the fashion industry?
Lea: Positive developments happening in this industry are increased sustainability regulations. Regulations play a crucial role in forcing companies in the fashion industry to adopt more responsible practices, closing the gap between awareness and action.
And what really needs to change?
Bert: For the industry to change, a collective effort involving manufacturers, government intervention, and consumer behaviour change is necessary. All three need to contribute to the transformation. Also, encouraging responsible production practices, enacting supportive legislation, and fostering a shift in consumer mindset are all important measures.
Lea: Examples like
Renewcell's bankruptcy show the difference between consumer intentions and actions. Despite people wanting change regarding sustainability, there needs to be more consumer engagement to support innovation, emphasising the need for efforts across those three fronts Bert mentioned [i.e. encouraging responsible production practices, enacting supportive legislation, and fostering a shift in consumer mindset].
What is the biggest misconception about sustainable clothing?
Bert: One prevalent misconception about sustainable clothing is that it is not fashionable. People are often pleasantly surprised by the quality and looks of our jeans, despite them being labelled as more sustainable. Some consumers are just not used to purchasing more sustainable products and associate them with a hippie or bohemian aesthetic.
Name a change consumers could make to become more conscious.
Bert: The most important adjustment consumers should make is to prioritise quality over quantity. Buying one high-quality pair of jeans is more conscious than purchasing multiple low-quality options. Consumers should think of spending money like voting with their wallets and supporting companies that are doing something good for people and the planet.
P.S. TIP: Watch the documentary "True Cost" and read the book "Doughnut Economy" for further insights into sustainable practices.
