Overview

Circular ONE is my winning hackathon project that is currently in pre-seed funding phase in its journey to becoming a official startup.

It aims to minimise textile waste and accelerate ‘Circular Economy’ by sparking motivation in consumers and other stakeholders in the value chain.

Its a technologically advanced blockchain-based waste management platform that incentives waste collection amongst users and closes the loop in the textile industry by connects all stakeholders in the value chain.

My Brief

BASF Germany is one of the few companies looking for sustainable growth and in turn be a part of the circular economy. We were asked to ideate and conceptualize a platform that’ll facilitate this circular economy for textile waste that involves all the stakeholders, from consumers to the recyclers and back to the consumers. Give waste a new life!

Figuring out ‘Why?’

Once we analysed the research data & understood the market better, we now had to figure out ‘why’ and ‘how’ did we end up here in the first place.

We needed to identify people’s needs and how to satisfy those without killing our planet.

Why do people discard clothes carelessly?

Why do people in developed countries use & discard more than their underdeveloped counterparts?

Why do most of the discarded clothes end up in landfills?

How do we accelerate circular economy in textiles?

Why is fast fashion the way to go nowadays?

How do we make people use sustainable fashion?

After deep searching the internet and interviewing experts later, we ended up concluding that this problem is threefold:

The end consumer, the OEMs and the rest of the stakeholders in the value chain.

The Consumers

They (especially the Gen-Z’s) are ones buying fast fashion of what’s trending. But not incentivising their return of clothes & lack of awareness leaves them feeling demotivated and ignorant to the facts.

The OEMs

They’re constantly looking for innovative yet cheap ways to make fashion. After all, they’re in the business of selling. They end up choosing non-eco-friendly materials because of the wide availability and inexpensiveness.

Other Stakeholders

The remaining stakeholders in the value chain want to make the best use of the available resources but can’t do so because of the huge effort that’s required to collect, sort and recycle the clothing.

After our team brainstorming session, we decided to choose the end consumers as our most important stakeholders as they are the trendsetters, decision-makers and disposers.

But the question still persists, ‘What is preventing them to buy sustainable alternatives?’

User Research

Why do they mostly tend to choose cheap and fast fashion? Are consumers willing to pay more for sustainable products or towards encouraging sustainability?

We now needed to understand what influences a consumer’s mindset in buying fashion.

Here are a few insights from our research

Transparency

Consumers appreciate more transparency in the textile value chain as to whether or not their clothes are recycled or dumped in a landfill

Study by McKinsey & Company
1/3 people
(33%)

1/3 people were choosing to buy from brands they believe are doing environmental good

International study by Unilever
73%
consumers

73% of consumers would change their consumption habits to reduce their impact on the environment, and almost half (46%) would switch to environmentally friendly products

Key Insights from Expert Interviews

"The biggest challenge isn't technology—it's creating economic incentives that align all stakeholders toward circularity." - Sustainability Expert, Textile Industry

"Consumers want to do the right thing, but they need to see tangible impact and receive recognition for their efforts." - Behavioral Psychology Researcher

Our Solution

The main reason people discard clothes the wrong way is that there’s no motivation and benefit for them to discard the right way except for their good samaritan attitude. We needed to revive that motivation.

Finally, we needed to remind them how much of a positive impact they’ll be making if they return their clothing like litres of water saved, CO2 emissions prevented, etc.

This extra boost was a pivotal reminder to push them towards sustainable alternatives.

Another way is to introduce a green label and using sustainable blockchain tech (like IOTA) we can keep track of a certain piece of clothing from its manufacture to where it ends up using the concept of a ‘Digital Twin’.

One way to do that was to partner with OEMs like Zara, H&M, Inditex, etc and incentivise every piece of clothing returned to them with vouchers, etc

For eg, a shirt bought with our Circular ONE label by a consumer will have the data of its characteristics (like its material, etc), month and location of manufacture. Once the consumer returns it in exchange for an incentive, he can now also keep track of where that cloth ends up (maybe as a Tesla seat cover, you never know 😀)

Designing the experience

Having developed the methodology to solve, I now needed to clearly define the functionality of the platform.

Using our research data, I summarized the functionalities that the app will solve to get a clearer picture.

Once the functions were in place, I needed to map out the user flows for different functions of the app.

A user should be able to
See their tokens and its value
Search for drop-off locations
Spend tokens for sustainable purposes
See & locate our partners
See the history of the rewards they redeem
For each product, see its respective characteristics
See how much waste they reduced
See the clothing they own & ones they gave away
Flow 1 - Assigning of token ID (Buying)
Flow 2 - Drop-off & Rewards

Now, I needed to design an experience that can accommodate these functionalities and flows without compromising on the user experience.

A little ideating and a couple of brainstorming sessions later, I concluded that there were 3 primary and 3 secondary design challenges.

Primary

#1

How do consumers know about and track their purchased clothing while also being aware of its present status?

Each individual item manufactured has its own unique Token ID attached to it which enables you to track it using the decentralized tech of Blockchain.

#2

How do users keep tabs on their rewards?

Every item of clothing returned gains rewards in the form of vouchers, Circular Coin (our cryptocurrency), donating to a worthy cause, etc. Every reward received gets transferred to their CircularONE wallet from where they can keep track.

#3

How do users know about our partner brands and locate them to shop and return clothes?

For better efficiency, we decided to ask consumers to return their clothes to one of our partner brands. In order to do that, they need to be able to know who are our partners and which is the nearest store.

Secondary

#1

How do users redeem their rewards inside the app?

#2

How do we give them more knowledge about this platform and initiative?

#3

Where should the sponsored content be shown (for ad revenue)?

The best solution for the 3 primary challenges was to have a dedicated section for each of those. This meant the user can focus on one task at a time, reducing cognitive load.

A ‘Home’ section where one can track their clothing, a ‘Discover’ page dedicated to our partner brands and a ‘Wallet’ section to keep track of their rewards.

We also decided to have an extra page named ‘Spend’ where we allow users to spend the rewards that they earned for their good deeds 🙂.

Ultimately, we ended up locking on 4 main sections of the app – Home, Discover, Wallet, Spend.

Home

The concept of Home was very simple – I need to give a quick glance at their most important stuff such as wallet, clothes bought & sold, tracking of each article of clothing (using non-fungible Tokens) and any promotional posters from our partner brands.

To solve this, I included a few of the wallet data like current balance, exchange rate and its growth. These are the most common data points people generally use typically with their wallets.

To solve this, I included a few of the wallet data like current balance, exchange rate and its growth. These are the most common data points people generally use typically with their wallets.

I also clearly segmented clothing bought and clothing sold for an easier scanning experience. So under ‘Bought’ they’ll be able to focus on the article’s characteristics and manufacture details and under ‘Sold’ they’ll be able to focus on where their clothing end up being (it could be used in someone’s tesla, you never know :D).

Each card corresponds to an article of clothing that they had purchased or returned and also shows the current status & Token ID for future references. Once a card is opened, all the information about that respective item is shown along with its predicted destination. There’s a QR code of the digital twin too which can be shared around for people to try on that item virtually (digital fashion).

Discover

This section of the app experience is dedicated to our partner brands and our knowledge section that enlightens users with anything interesting happening in the world of sustainable tech.

So under ‘Bought’ they’ll be able to focus on the article’s characteristics and manufacture details and under ‘Sold’ they’ll be able to focus on where their clothing end up being (it could be used in someone’s tesla, you never know :D).

The ‘Know’ subsection keeps the users up to date with intriguing stuff in sustainable tech. The mode of content delivery can be anything but primarily videos and bite-sized content to begin with, as the TikTok era has made people’s attention span limited.

Wallet

This section solves one of the more important challenges – to show their rewards and give them insights about their returned clothes.

The first thing you see is your current Circular Coin balance and a graph showing its past performance and future predictions.

Up next, users see insights about their returned clothes, how much water they’ve helped save, how much CO2 they’ve prevented, etc. This serves as an extra push for them to act on change and accelerate circular economy. I’m gonna be honest here, it sure does feel good to do good haha :D. Right?

Spend

As the name suggests, this section is designed for you to reap the benefits of your good deed.

Here, there are various options where you can redeem your rewards with. You can choose to get gift cards from partner brands, support honourable & charitable causes, etc. Let’s spend!

With the user experience sorted out, I fired up Figma and commenced designing! 😎

The Design

My Design Principles

Minimalism
Clarity
Accessibility
Remembrance
I chose green as the primary colour it not only shouts ‘sustainability’ but also represents ‘trust’.

This chosen colour palette resonated the best with the idea and its pastel nature gives it a friendly tone too.

When it comes to design clarity, every element is sufficiently spaced to show the necessary data.

For eg, the card to show the clothes (bought & sold) shows key data at a glance like the Token ID, Current status, Name, Color, etc.

My decision to choose a floating nav bar (at the bottom) instead of a fixed one was primarily to give the user a sense of space a better & an immersive app experience.

And the fact that it hides away when you scroll down, makes it even more immersive to use.

I’m a big fan of fonts & font pairings because a well-chosen pairing can give the right tone and emotions to a design.

In order to look friendly and inviting, I paired Rany (a casual & aesthetic sans-serif font) for display and primary headings with SF Pro Text (a classic tried and tested sans serif font from Apple) for secondary headings and body text.

These, paired together, gave a sense of openness and sophistication.

The Outcome & Beyond

The future of sustainable consumption isn't just about doing less harm—it's about creating systems where doing good is naturally rewarded and economically viable for everyone involved.

The app solved the challenges that was put our way and effectively. This ended up winning us the ‘BASF Challenge Award’ and ‘Best Pitch Award’! Winning these 2 awards is the best feedback we could have!

Lessons Learned

The biggest lesson I learnt was to cope under pressure. Doing all this in under 48 hours, unlocked a new level in me, which I never knew existed 😀.

Circular ONE represents more than just a hackathon project—it's a proof of concept for how technology can solve real-world environmental challenges while creating economic value for all participants. The success of this project demonstrates the power of user-centered design combined with innovative technology to address complex, systemic problems.

The transition from hackathon winner to potential startup has reinforced the importance of thorough user research, stakeholder alignment, and creating genuine value propositions for all participants in a circular economy. As we move toward funding and launch, the focus remains on maintaining the user experience quality that made this project successful while scaling to create meaningful environmental impact.
