Trobak, give value to your waste

Trobak is a smart composter that helps you reduce your impact on the planet by sorting your food-waste and turn it into a healthy usable compost in your apartment. Its connected features offers you a whole new experience and most of all, it is totally odorless. So forget about bad smells & insects, these pains are now part of the past !


Help the planet, sort your waste without pain

With Trobak we want to help each one of you to fight one of the main problem of our time: food-waste. We want to reduce the part of food that ends up in the trash and gives it value.


Throw and get back

With Trobak you'll be able to turn your food waste into a perfectly healthy & usable compost for your interior plants or garden


With the app, you can follow the process status, ask question to Trobot and find people around you to share your compost with.


Thanks to the 100% natural additive we developed odors won't be an issue anymore. Reduce your impact on the planet without pain!

More than just an app

The application is full-part of the Trobak experience. Through it, you'll be able to follow the transformation process, ask questions to our mascot Trobot about what you can or cannot put inside it, and access the community platform in order to share information or your extra compost production.
