UI/UX :  

Throw it in App instead of the street

Problem Identification

On visiting my friend who resides in Chennai suburban, I noticed overflow of her household waste. On discussing further, she conveyed that door-to-door collection of waste in her neighborhood was substandard which compelled her and her neighbor to dispose of the waste in street. So, I decided to design an app which will minimize the gap between people and conservancy officers.

Design Thinking Process



More than 90% of waste in India is considered to be dumped in an unsatisfactory manner which leads to piled up landfills. The poor waste management in India is owing to the lack of awareness about 3R’s methodology. Around 75% of municipal garbage in India is being dumped without any processing.

Product Strategy

Design solution is attained by focusing on the user’s expectations and requirements in each phase of the design thinking process. Since we are designing our product based on the principle of User Centered Design(UCD) which will provide good User Experience(UX).

User Centered Design focuses on the user, business and technological constraints.

In order to create an effective value-based product strategy, all I did is asking the right set of questions. Below are some questions I prepared and found answer for those which helps me to build the strategy of my product.

  • Is this a real problem in our society?
  • Who are the target audience for our product?
  • How does our product address the needs of customer?
  • What unique value does our product holds to beat competitors?
  • How I planned to deliver an unique values of my product to user?

UX Strategy: User Centric Design Canvas

I decided to use the User-Centered Design Canvas tool as my strategic plan it’s heavily based on a user-centric approach and helps me to focus on both user and business side.

User Survey

UX Surveys are quick and relatively an easy way to get data about users. In this project, I have used the user survey to fathom people’s practices with respect to waste management.

The sample size of the survey is 25 and I had used Google form to record the survey. Shown below is the quantitative data based on the survey.

User Interview

After conducting an online survey to analyze user practices, I interviewed five people who had difficulties in disposing the waste. Below are the sample questionnaire asked in user interview,

  • How do you treat waste pickers?
  • Do you segregate waste based on their property?
  • Are you aware of 3R (reuse, reduce, recycle) methodology?
  • Do you believe that the current waste management system is effective?




The challenge was to design an app to give an innovative solution to people’s complex problem by incorporating the principles such as aesthetic-usability, easy navigation between the screens, legibility, affordance and minimal performance load.

  • To initiate an engaging factor for the users.
  • To simplify the visual and functional aspect of the app.
  • To make the booking, order tracking, point’s allocation in easy way.
  • To create an app which would be well received across various age groups.

Design Features

Based on the insights from the above experience, I conceptualize to enumerate the main features which will make OmniTrash a solution to the issue,

  • Users can prefer the pickup time and vendors
  • The users can track the waste pickers before the pickup
  • Chat facility enables users to interact with their neighbors and waste pickers.
  • The photograph of the waste picker and QR code will ensure user security.

User Flow

Now I have moved into the vital phase of my design process, that I want to create the user flow for my app. User Flow is the path a user follows through an application.

Solution Wireframes

In order to achieve the design solution via MVP’s, the skeletal framework of the design was done first. After a set of rough sketches, I had made the designs of every screen.

Screen Explanation

1.Onboarding Screen

Direct signing in will enable the user to complete the login or register process simple, as onboarding screen will become redundant.

With Onboarding, I have shown the value of the app, highlights the key benefits and some features of the app.

2.Sign-Up and Sign-In

Sign in screen will incorporate a social network login enabling the user to register easily, this will minimize the Login failure rate and allows the user to login with multiple identity proofs.

Sign-up screen will request the user to fill up only the minimum requirements. Forget password screen will help you the reset your password where OTP number is sent to your mobile.

3.Home Screen

Home screen will be designed in such a way that it will enable the user to navigate to their destinations smoothly. The actionable information is placed in the form of cards for easy access.

The bottom navigation bar incorporates a menu where the user will be taken to the top-level navigation destination associated with that icon.

4.Order Placement:

The user can scale the approximate weight of their household waste and schedule the approximate pickup time which will enable the waste pickers to schedule their pickups accordingly.

Order summary screen provides detailed information about the waste pickers and QR code will ensure the authenticity and confirm the waste pickup.

Popup screen inform users about a task and can contain critical information about the performed task.

5.Whistle and Map Screen

Providing Location based images will aid the waste pickers to spot the location easily.

Warning rate will provide information about the flow and intensity of the garbage.

Map screen will be designed in such a way that we would be able to select any location employing multiple ways.

6.Chat Screen

Chat feature in this app helps users to interact with their neighbors anytime and waste pickers during the time of waste pickup.

Call option are placed at the right corner which will helps the users to call their desired one anytime.



Scan this QR code to view the prototype


To validate my MVP, I conducted a remote usability test with 5 users. Users sample are same as used in user interview. The goal of the usability testing is to identify usability problem before moving to the development phase.

Design solutions are redefined based on user feedback.

1.Forgot Password Screen

4 out of 5 users prefered OTP with number over OTP with mail reset link.

2.Whistle Booking Screen

5 out of 5 users said its is difficult to guess the types of waste present in roads.


3 out of 5 users said to add filter based view time.

Impact of OmniTrash Mobile App in

Business: It will bring more coustmer into business.

Social: It will Improves the life standard of waste pickers.

User: It will helps user to dispose the waste easily and quickly.

Environment: Segregating the waste at zero level reduce landfills.

Future Iterations

After the user testing, I understood users are expecting some more features in the app. Since prototype is meant to be a minimum viable product (MVP), many features were excluded in the design. Below things will be taken into consideration,

Intergrated app

Users can throw all types of waste in a single app.

Capturing the video and publish

Users can capture and publish the video if they saw someone littering in public place.

Sharing the achievement on a social platform

Users can share their achievement in a social media platform sites like twitter, facebook, WhatsApp etc., which makes them proud and also it will be an unpaid promotion for our app.

Take Aways

Design is a solution to a problem. Art is a question to a problem. — John Maeda

This project improved my problem-solving skills, the idea nurtured further by thinking on the user perspective.

Refining and Redefining the product and user flow based on the usability testing will help the product to stay unique from competitors, repeat again from the ideation stage until the target user finds it as the featured solution.

I’m delighted by the outcome of OMNITRASH and I firmly believe that this app will truly be a solution to the problem statement and will be accepted by the target user.

Special thanks to Sakin Kumar for his design advice and Ajay Gifto for his support and also I need to thank people who took the time to tell me about their thoughts, painpoints, experience and test my prototype.
