    According to Waste Atlas, each person in Japan produces an average of 356.2kg of waste per year and, as a whole, Japan generates 45,360,000 tons of municipal waste per year however Japan doesn’t have enough space for landfills for these amounts of waste and as a result, they created a waste separation system which aims to reduce the amount of waste that is produced. But the reality is that not even locals or long-time residents follow the rules due to level of complexity and a lack of understanding, and as a result, the government ends up with more waste than recyclable materials.

    “Japan has one of the most complex waste separation system in the world, it varies depending on your location where you might need to separate up to 10 different types of waste and the pick-up schedule changes for each neighbourhood.“

    WHAT DO WE DO? – We are a company who makes garbage disposal easy and effortless by designing smart trash cans.

    HOW DO WE DO IT? – By making a smart, rentable trash can with a companion app that helps educate foreigners through a growing knowledge base.

    SOCIAL IMPACT – We want to educate foreigners in Japan who don’t know how to separate garbage according to council laws and cannot follow the right schedule for disposal. As well to work towards SDGs 11 and 12.



    SEARCH BAR – A knowledge base with accurate information regarding how to correctly dispose daily items.

    CALENDAR – It contains a monthly planner of the garbage schedule according to your neighborhood so you can prepare in advance and stay on top of it.

    DASHBOARD – Connect all of your Smartrash™ and check the level of your garbage even when you are outside.

    ALARMS – The app will automatically set alarms for you to remember to take out the garbage on the correct day according to your neighborhood schedule.


    SENSOR – A distance sensor placed in the lid of the smartrash reads the levels of garbage and sends the information to the app.

    DESIGN – Every smartrash is covered in different icons depending on the type of garbage you can throw. It is an easier way for the user to visually recognise and separate their garbage.

    ODOR CONTROL – A deodorant located in the top of the lid protects and maintains your Smartrash™ and house from bad smells.
