Overview
About the project
Eco Contributions was my final-semester concept for Blinkit. It proposes a way for customers to return delivery bags with their next order and receive wallet credit. I wanted to work with a service people already used.
The challenge
The problem
I first considered wider questions around waste management and food grading. Those ideas were too broad for this project. Delivery bags gave me a more specific problem to work on: they accumulated at home, while the next delivery already provided a chance to hand them back.
Design decisions
Returning bags with the next delivery
I initially looked at food adulteration and waste management. The project became more manageable when I focused on delivery bags: customers already had a delivery partner coming to their door.
Narrowing the problem
Food adulteration & waste-management systems
Use the existing delivery service, without adding hardware.
Return packaging during the next delivery.
Persona in the research deck / customer
Arun
Bags pile up in his hostel room. He wants simple rewards and is unlikely to make a separate trip to recycle them.
Let him return bags when his next order arrives.Persona in the research deck / operations
Rajesh
He manages packaging and deliveries at the warehouse. Checking returned bags would add work to an already busy operation.
Show who checks the bags and how the return gets recorded.The proposed service loop
- 01
Customer
Save bags for the next order
- 02
Delivery partner
Receive and verify returned bags
- 03
App
Confirm return and wallet credit
- 04
Warehouse
Assess bags for potential reuse
Still to test: which bags can be reused, how long checking takes, and whether people keep returning them.
Source & context
The project deck contains the research, personas and early concepts behind this flow. Bag returns remained a proposed service; warehouse operations and business results were not validated.

What I did
I used a survey, warehouse interviews and focus groups to develop the concept. The proposed flow has the customer hand back bags, the delivery partner check them, and the app confirm wallet credit. It still needs testing in an actual delivery operation, particularly the time required to check bags and whether they can be reused.
