Making reuse the new normal: Encouraging new habits with the Mercari Ecobox

Mercari Experiments

Project overview

At Mercari, we aim to create a circular economy that makes the most of the world’s finite resources.
We want to contribute to resolving environmental issues not only by encouraging and supporting the reuse of various goods, but also by making consumer activities more sustainable through our business.

In a survey we conducted in 20211, we found that around 75.6% of the respondents were choosing to throw away things they no longer use. This was a 1.8% decline from the same survey conducted the previous fiscal year2, and we are seeing this percentage decline year by year. In addition, we found that of the respondents who said they throw away items that can still be used when they have no use for them, 82% of people said they felt that this behavior was wasteful.

  • Given these results, we wanted to find a way to help people move away from disposing of the usable items they no longer have use for, and that’s when we came up with the Mercari Ecobox—a simple place for people to keep their items that is separate from their closet or the trash.
    By developing the Mercari Ecobox, we wanted to change the mindset people have when they're deciding whether to throw something away in order to help foster more sustainable habits.

What is the Mercari Ecobox?

  • The Mercari Ecobox is a place for people to temporarily store and periodically look over the clothes, books, trinkets, dishes, and other items they no longer use but cannot bring themselves to throw away as trash.

    Our idea is for people to start using the Mercari Ecobox to store any usable items they no longer use. Then, they can revisit the contents now and then, and choose to sell items or give things away to people who need them. Creating this habit will gradually make it the norm for people to find ways to reuse items instead of throwing them away, and it will bring us one step closer to realizing a circular economy.

    We have started by providing Mercari Ecoboxes to the residents of Gamagori City, Aichi Prefecture, and Kamo City, Niigata Prefecture, as a proof of concept to investigate whether they are impactful in encouraging a reuse mindset and sustainable behavior.

    Currently, our society sorts trash into categories assuming that all items in the trash are to be thrown away. However, through this Mercari Ecobox initiative, we hope to promote an alternative category to burnable and non-burnable trash—by getting people to consider the option of reuse, we aim to ultimately bring about a culture where people are reducing waste and using things for longer.

Experiment method

  • From May 30, 2022 (Zero Waste Day), in collaboration with Gamagori City, Aichi Prefecture, and Kamo City, Niigata Prefecture, we provided 300 free Mercari Ecoboxes to the residents of each city as a proof of concept.
    We will survey city residents who used the Mercari Ecobox, and investigate over 2–3 months whether it caused any change in their behavior or mindset when throwing things away.

    Future Outlook
    Based on the results of the proof of concept, we will consider plans to spread and expand usage of the Mercari Ecobox.
