Frequently asked questions
"Circular Cashback"
Here you will find the most frequently asked questions about our "Circular Cashback" buyback system and the material naNea, from which the circular products are made. We also provide information on how to return your worn product and receive payment for it.
General information on the "Circular Cashback" buyback system
As soon as you have signed out your circular product, you can send it back to us. To do this, scan the QR code on the label or visit https://nikin.ch/circular-takeback. We will buy your product back. For a T-shirt costing CHF 79.90, this is a maximum of CHF 20. You will receive CHF 10 for the material of the T-shirt and a maximum of CHF 10 for wearing the T-shirt for a long time. The longer you wear it and look after it, the more you get back. You will also receive a return label from us.
No, we will send you a return shipping label with the return.
"Circular Cashback" means that we buy back all our circular products in order to reuse them in a closed loop. The aim is to avoid waste and reuse raw materials again and again. This is also the name we have chosen for the buy-back system, where we pay a maximum of 25% of the sales price of circular NIKIN products back to you.
You receive a fixed amount for each new year started. In the case of the T-shirt, for example, it is a total of CHF 10, spread over 5 years. That makes CHF 2 per year. You are entitled to this for the first time after the first year from the date of sale and then as soon as at least 6 months of each year have passed. For example, if you bought a T-shirt on November 15, 2024 and want to return it on September 10, 2026, then you have worn the T-shirt for 1.5 years and will receive CHF 4 back, in addition to the CHF 10 for the material of the T-shirt. However, if you want to return the T-shirt on February 20, 2026, then 1.5 years have not yet passed and you are entitled to CHF 2 for wearing it for one year.
If the circular product breaks within the first few days or months, e.g. because it got a self-inflicted tear while hiking, then you can send it back to us. In this case, we will pay you money for the material and buy it from you. However, you will only receive money for wearing it for a year or more. We also encourage everyone to wear their T-shirts for as long as possible and to take good care of them.
This is a new model and we have to build it up in such a way that we can be profitable with it in the long term and also scale it up. Our goal is to replace all normal products with circular products in the long term. If the discount were too high, we wouldn't earn enough from it and it wouldn't be interesting enough for other retailers in terms of price or profitable for us. We have therefore programmed our online store in such a way that general discount codes cannot be applied to circular products.
For accounting and legal reasons, after 5 years the right to repurchase by NIKIN or resale by the person who bought the product expires. However, it is absolutely in our interest that the product is worn for as long as possible and the quality of the products is also high enough to be worn for more than 5 years. Everyone therefore has the right to contact us, even after 5 years, and we plan to be accommodating in the interests of sustainability and the circular economy.
You can follow the normal process as if you had bought it directly from NIKIN . This means that you can also scan the QR code on the label or visit https://nikin.ch/circular-takeback.
No, there is no such thing. If the entire product, e.g. the T-shirt, is returned, regardless of how damaged it is (e.g. in the form of tears), we will take it back. However, if a large piece of the fabric is missing (at least 10% of the total fabric), e.g. both sleeves, then we reserve the right to reduce the amount to be paid at our discretion.
The product is checked by internal experts. We can also check the edition based on the serial number marked on the inside.
We have set up the model in such a way that we can implement it in the long term and for all circular products. We firmly believe that, on the one hand, we can ensure that the material comes back and, at the same time, we can extend the existing life cycles of the products and materials through financial incentivization.
The normal guarantee, as with non-circular products, naturally also applies to circular products.
The T-shirt made from naNea that we launched in early 2023 was our first step towards circular fashion. Back then, the take-back process involved industrial composting. Now the product is taken back and then recycled together with other products from naNea and processed into a new yarn that has the same quality as the first fiber. Another new feature is our comprehensive "Circular Cashback" program, which makes the return and recycling of T-shirts even more attractive. With this program, we ensure that the materials remain in the cycle and can be processed into new products again and again.
Product and material details
naNea is an innovative, biodegradable co-polyester that has been specially developed for the circular economy and the textile industry. It can be recycled again and again in consistent quality without any loss of quality. It was developed by the company OceanSafe AG from Bern.
As a synthetic fiber, naNea is currently still made from petroleum-based raw materials, as OceanSafe wanted to quickly provide a solution to the challenges of the textile industry and recycled materials were not yet available in industrial quantities during development. Furthermore, the current material offers a consistently high quality, which contributes to an extended lifetime of the textiles and longer enjoyment! However, OceanSafe now attaches great importance to producing naNea from recycled materials in the future. In future, your returned shirts will also contribute to this at the end of their useful life.
naNea has been proven to degrade in seawater to over 93% within 99 days, according to the ASTM D6691 standard. This degradability is the result of naNea's special polymer structure, which does not require the use of additives or enzymes. The material is designed to be inherently biodegradable. Crucially, naNea contains no toxic substances or harmful microparticles that could be released during degradation. The material is biodegradable not only in the sea, but also in soil and landfill environments.
During decomposition, naNea breaks down into natural components such as carbon dioxide, water and biomass. These degradation substances are thus present in the environment, are not ecotoxic and do not cause any environmental pollution. Importantly, naNea leaves no harmful residues such as heavy metals or toxic chemicals, which are often found in conventional polyester fibers. Thanks to Cradle to Cradle Gold™ certification, the material is safe for the biological and technical cycle, even after its use.
naNea is the first synthetic fiber in the world to achieve Cradle to Cradle Gold™ certification. Most notably, naNea is the only material in this category to achieve the Cradle to Cradle Platinum rating in the "Material Health" category - naNea is free of toxic ingredients and heavy metals. What makes naNea truly unique is its ability to biodegrade over 93% in the ocean in just 99 days. This makes it one of the few synthetic fibers that meet the strict requirements for biodegradability. But the most impressive feature of naNea for us is its recyclability. The fiber can be recycled over and over again with consistent quality.
For example, an old T-shirt made from naNea can be chemically recycled to make new polymer, which is spun into yarn that can then be processed into a new product - such as another T-shirt. In this way, the material always remains in the cycle and avoids waste, while at the same time conserving natural resources.
Yes, but not yet on a large scale. The recycling processes have already been successfully tested several times on a small scale by our partner OceanSafe. However, we have not yet collected enough returned T-shirts to apply these processes on a large scale. We have been offering our innovative naNea T-shirt since 2023, and unfortunately no T-shirt has been returned as of November 2024. However, we are confident that the return rate will increase with the new "Circular Cashback" program.
NIKIN expects that the margins for circular products may initially be somewhat lower compared to conventional products, as the introduction of a new business model and the implementation of recycling and payback processes require financial and time investments. In the long term, however, margins are expected to improve as material costs are reduced by the closed-loop system and process efficiency increases.
NIKIN is not looking for investment in the form of money, but is always open to partnerships that support the development and scaling of the circular model. We are already working with partners such as OceanSafe and are interested in further collaborations that support our goal of a beautiful nature and a sustainable fashion world. If you are interested, companies can contact our team directly.
NIKIN plans to increase sales through various measures, including targeted marketing campaigns, educating customers about the benefits of circular products, expanding the product portfolio to include more circular items and introducing incentives for customers to wear and return their clothes for longer. In addition, NIKIN will continue to enter into partnerships and collaborations with other sustainable brands and organizations.

Goals & vision of NIKIN
NIKIN wants to bring about a positive change in the fashion industry and has committed to offering 100% circular products by 2030. We want to show that fashion can be sustainable and innovative.
The circular economy reduces waste, conserves resources and promotes the sustainable use of materials. Customers benefit from long-lasting products and a financial incentive for sustainable behavior.
NIKIN is planning further product launches with circular materials and is working on new business models.
For NIKIN, the circular economy means creating products that do not harm nature and remain in a closed cycle. The focus here is on extending the service life, for example by repairing. Only at the end is a product either composted or recycled without losing any of its quality. Our goal is to make all our products fully circular by 2030, thereby actively contributing to a more sustainable world and cleaner nature.
Financial incentives and buyback program
This depends on the product. For the T-shirt, you will receive CHF 10 for the material of your old T-shirt and up to an additional CHF 10 the longer you have worn and cared for it. For all other products, you can see this on the respective product pages.
The financial incentive is intended to motivate customers to wear their products for as long as possible and to look after them carefully. By extending the lifespan of the products, we reduce the need for new production and thus the ecological footprint. This supports our mission to minimize waste and protect nature. Furthermore, our experience and that of other clothing brands shows that without financial incentives, the hurdle for many customers to return the product is too great.
No, there is no penalty if you do not return the product and do not sell it back to us. However, in this case you will not receive the material value (e.g. CHF 10 for a T-shirt) or the additional reward for wearing the product for a long time. Our aim is to take back as many products as possible in order to recycle them and keep them in circulation.
Transparency and sustainability
NIKIN has committed to offering 100% circular products by 2030. We are focusing on materials such as naNea, which can be fully recycled, and developing take-back programs such as "Circular Cashback" to ensure that materials are returned to the production cycle. We are also working on other projects such as developing a circular shoe with Ochsner Shoes, taking back old (also non-circular) clothes with Turns and more.
All returned products undergo a Cradle to Cradle certified recycling process, which is carried out in collaboration with our partner OceanSafe. OceanSafe ensures that the materials are turned into new yarn from which new products can be made.
Yes, our take-back system is based on a Cradle to Cradle-certified recycling process, which is carried out in collaboration with our partner OceanSafe. This certification ensures that the returned products can be fully recycled in an environmentally friendly way and remain in the cycle. OceanSafe ensures that the materials are turned back into new yarn that is used to manufacture new products. Through this rigorous certification and regular auditing, we ensure that our take-back system remains sustainable and environmentally friendly.
Not at present, but NIKIN has set itself the goal of measuring and continuously reducing the company's overall CO2 footprint. Reducing CO2 emissions is an important part of our sustainability goals. However, as our resources are limited, we have currently decided to increase our focus on developing circular products and business models. We believe that promoting the circular economy will lead to a significant reduction in environmental impact in the long term, as it reduces waste, conserves resources and minimizes the need for new raw materials.
Yes, the circular economy is more sustainable overall, even if transportation and recycling energy are taken into account. Closing the material loop saves raw materials and minimizes the production of new materials. OceanSafe is also constantly working to improve the energy efficiency of recycling processes and relies on renewable energy (at least 50% for each part of the supply chain) to further reduce its environmental footprint. Despite the transportation and energy required, the circular economy is a much more environmentally friendly alternative to the traditional linear economy.
