Drop It Off

Streamlining the Donation Process to Reduce Consumer Waste

Project Overview

Project Type: University Capstone Project

Project Timeline: 2024 - 14 weeks

Group Size: 5 Students

My Role: UX Researcher | UI Designer

Tools Used: AdobeXD, Miro

Outcome: High Fidelity Prototype of Mobile App

The Problem

Reduce, Reuse Recycle. We’ve heard it all before. But how many of us have the time or information to do so effectively? With a growing culture of consumerism, consumer waste is a concerning issue that we decided to tackle, and it started by answering this very question.

From surveys and user research, we found that while many individuals and businesses want to donate their unwanted items, they often lack the time, information, or motivation to do so. Charities, on the other hand, struggle with an overflow of irrelevant donations while also lacking the resources to sort and distribute them effectively.

This created a stakeholder paradox—while donors and charities share a goal of reducing waste, inefficiencies in communication and logistics lead to excess landfill waste.

Pain Points

Consumers Lack the time or knowledge of where to drop off items.

Charities Receive too many irrelevant donations, creating logistical burden.

Resale Platforms Require too much manual effort for users to list items

User Research

To fully understand the problem space of consumer waste and donation inefficiencies, we identified 5 key stakeholder groups in order to map out key influences within the industry:

  • Donors who wish to give away their items or consumers

  • Charity workers who want to focus on their primary duties without being overwhelmed by

    the logistics of donations

  • People in need who require these goods

  • Circular Economy Services which act as a platform to store and exchange the ownership

    of unwanted items to those who needs or wants it more, and

  • Retail Industries which produce all these consumer goods and will persuade people to

    continuously buy new items as they do not want to lose customers to make profit.

To better understand these influences, we conducted user interviews with 6 participants from 3 of these groups. This allowed us to develop an overview of various users’ wants and needs, and how they might clash or compliment each other.

💡 Key Insights from Interviews:

  • Consumers struggle with uncertainty - they don’t always know whether their items can be donated, where to donate, or if it’s even worth donating.

  • Time commitment is a major barrier - many participants admitted they often threw away usable items because donation drop-offs were inconvenient.

  • Charities are overwhelmed - NGOs often receive too many donations at once, many of which are unsuitable (e.g. damaged goods).

  • Retail brands lack transparency - some brands market themselves as sustainable but don’t provide clear information on how much donated/recycled material is actually reused, leading to mistrust.

These insights directly shaped our design decisions, leading us to prioritise ease of use, transparency, and efficiency in our solution.

Initial Idea Iterations

Once we had a deeper understanding of the problem space, it was time to brainstorm solutions. We wanted to explore a broad range of ideas to ensure we considered all avenues.

We developed 5 quick mid-fidelity prototypes of potential ideas and conducted user testing through surveys and interviews with 5 stakeholders. Our survey results allowed us to develop our final solution, which was a combination of 3 of our ideas that were found to be the most useful and relevant to users.

How To Trash - An educational wiki to teach users how to responsibly dispose of or donate unwanted items.

SecondScan - An AI based scanner that identifies if an item is suitable for donation or reselling based on its state of wear.

The Solution

A digital platform that connects donors with charities that need specific items, making the process fast, transparent, and sustainable.

Drop It Off - A map-based interface that connects users with unwanted items to donation centres in need of those items

Key Features

Mid-Fidelity Prototypes – Interactive screens in Adobe XD for usability testing.

AI-Powered Scanning

Users can scan an item to determine if it should be donated, sold, or recycled depending on its level of wear and usage.

Educational Content

Articles on sustainable waste management and donation best practices for users to educate themselves on sustainability.
