May - August 2024

“Could you check how many plastic bags are in your house?”

“Could you check how many plastic bags you have in your house ?”

This is the plastic bag from a 2 students apartment…

- 20+ plastic bags in total, by roughly counting
- Most of them are from the grocery store

“How many plastic bags do you have right now?”

- Almost half of the responders claim about 15+ plastic bags
- After asking to confirm, they find out the
exact number is larger

Where are those bags coming from?

Nowadays, we have alternatives of plastic bags. Why still so many plastic?

Plastic Bag /
Paper bag

Personal Cart /
“Granny” Cart

Shopping Bag / Reusable bag

Thinking About This…

Sometimes people go to the grocery without a plan, for example, after school / after work

It’s difficult for people to always carry the grocery bag with them when they go to work / school


What if we could design a new grocery shopping cart that can push from the store to home

So customers don’t need to purchase plastic bags

Let Me Introduce “Habit”

And they can bring the groceries home more easily

Concern On Bags

Although customers have an extra paper bag for reinforcement, they remain concerned about durability. Also, carrying heavy groceries from the store to home often comes with physical pain.

Collect & Repair

Habit is owned by a specific company, not individual supermarkets

At night, the company replenished the Habits in the stores

After that, the company collected the Habits from the LockStation in public for repair and cleaning


Most of the groceries happen without a plan. Sometimes people either finish their duty and suddenly decide to come or forget to bring their bags.

There are currently two key issues to address:

  • Customers who walk to the store often do not bring reusable bags, leading to increased plastic bag usage.

  • Carrying heavy groceries home is inconvenient and physically tiring.

Since customer behavior before arriving at the store is unpredictable, can we instead provide a service or product at the checkout to address these issues?

Behavior Research

A week-long behavioral observation study across seven supermarkets, examining consumer shopping habits.

Surveys and interviews with 42 participants representing varied age demographics and geographic locations.

Walking To Grocery

Compared to customers who drive to the store, those who walk or use public transportation are more likely to purchase plastic bags. They are commonly located in urban areas with shorter travel distances
