Reducing waste, building community.

Introduction

Introduction

As part of my bachelor's thesis, I developed this matrix to summarise the challenges and opportunities for community food-sharing initiatives. In this project, I will be exploring different approaches to tackle P2P food-sharing across neighborhoods with a deeper focus on digital solutions.

As part of my bachelor's thesis, I developed this matrix to summarise the challenges and opportunities for community food-sharing initiatives. In this project, I will be exploring different approaches to tackle P2P food-sharing across neighborhoods with a deeper focus on digital solutions.

Research insights

When applying thematic analysis to the primary research data, a few key insights emerged relating to the motivations and barriers for P2P food-sharing. Those insights shape the core principles that any digital or non-digital solution should address in order to address logistical and social challenges facing community food-sharing in Berlin. Therefore, the designed solution should be:

01

Low-friction

Low-friction

Addresses logistical barriers

The solution should take away the friction of arranging a date & time for pickup, questions about packaging and kitchen boxes, and most importantly, make sure items are within walking distance to avoid over-commitment and no-show.

Example:

Common cooking kitchen

Community fridge/space

Someone delivering the food to you?

02

Informing and Transparent

Informing and Transparent

Addresses logistical barriers

The solution should enable users to offer as many details about their listing seamlessly and naturally. Food is a very intimate item for people, so they want to make sure the item they're offering is presented satisfyingly, and the items they're receiving match their dietary preferences and allergy concerns.

Example:

A sticky note with all dietary details

Food with labels and instructions

Someone telling you the ingriedents

03

Inclusive & Community oriented

Inclusive & Community oriented

Addresses social barriers

The solution aims to bridge the social gap and break the ice between neighbors. Therefore, it should reflect the community sense and offer a space that feels safe and humane for people to feel invited to exchange food items and even further bond over it, instead of being a mere transactional process.

Example:

Community dish-parties

utilizing screens in elevators

Stickers/posters in hallways

04

Progressive & Scalable

Addresses social barriers

The solution should adapt to the progressive nature of food-sharing as a trust-based activity that relies on the buildup of interactions and reciprocity. How can the individual build increments of trust from sharing maybe a pack of chips to sharing a loaf of bread to requesting some salt on a Sunday?

Example:

Trust badges and ratings

Airbnb/Couchsurfing trust models

05

Habit building

Addresses social barriers

The solution should focus on building new habits and a culture around the concept of food saving and sharing. Habit building is about repetition and linking of daily activities to new ones. Can we link evening social media scroll with new food-saving habits?

Example:

Streaks concept

Daily reminders

Donating a penny every time food is wasted

Now the goal is to assess which solution, digital or non-digital, can bring most benefits from above while introducing least struggles. To assess that, I conducted an assessment of different solutions based on the criteria above.

Solutions Overview

Community fridge/sharing space

Simple to integrate in daily-life, one-time setup

High cost, requires physical setup

Low-friction

Informing & Transparent

Inclusive & Community oriented

Progressive & Scalable

Habit building

House Group chats

Low-investment, no learning curve

Hard to establish habits, lacks structure

Low-friction

Informing & Transparent

Inclusive & Community oriented

Progressive & Scalable

Habit building

Food-sharing apps*

Easy to adapt and scale, clear focus

Requires digital presence, needs active integration in daily life

Low-friction

Informing & Transparent

Inclusive & Community oriented

Progressive & Scalable

Habit building

*Depending on the specific app, the values of the metrics above can change, so the values are just an indication of the potential of such solution compared to others.

Review of Existing Digital Solutions

Since my project is focused on digital solutions, I started reviewing apps that try to solve the same issue and analysed what works and what doesn't in their user experience.

The focus was on the "Olio" app, as it seems to be addressing a very similar segment and tackling the same problem with the same solution approach.

To develop insights, I conducted a UX audit by downloading the Olio app, taking screenshots, and highlighting what is working well and what seems to be confusing for the user. Additionally, I conducted online research through platform such as Reddit and online blogs where users express their happy moments and pain points with the Olio app.

In addition to Olio, I analysed apps that successfully build habits and social buzz around their experience. I specifically looked at "BeReal" and "Duolingo" as two of the most common apps that have their success hanging on the idea of consistent repeated visits for the app to understand how to engage users on regular basis. I also looked at the "Strava" fitness app, with a focus on the idea of "badges" and "challenges" and their role in keeping users engaged and motivated to achieve their workout goals.

High no-show rate: Consistent complaint among users. Potenially for the wide-range of distance covered.

Too many features: The app offers food and non-food exchange with both free and paid possiblities

Not directly clear what allergies the food could include or whether it's halal, vegan, etc..

Branding

Derived from the German word "Teil", which means "Share", I decided to name the app "Teilo".

I decided to follow simple branding while staying mindful about the choice of typography and colors. That's why I decided to use a simple logomark with a font that is both playful and engaging while not looking too out of balance.

For colors, I decided to combine green and orange as primary and secondary colors. Green, the primary color, reflects food and is present across food-sharing platforms, making it recognisable. On the other hand, orange is a warm color that evokes a feeling of community and togetherness.

Wireframing, UI, and Prototyping

I started with low-fidelity sketches to outline core flows, quickly transforming ideas into tangible screens.

Wireframes evolved into high-fidelity UI mockups, focusing on usability, accessibility, and visual clarity.

Interactive prototypes were created for user feedback, allowing for rapid iteration on design decisions.

Testing

User testing sessions informed refinements to navigation, visuals, and features. Feedback loops helped address issues before launch.

The result: a more robust, user-focused product that better meets the needs initially identified.
