After four and a half years of development, the startup Greenzy is launching an ingenious product: a connected indoor composter for households to help them recycle their kitchen waste without the usual inconveniences such as odours, flies or other insects... It is now possible to pre-order it on the Ulule platform until 9 December at a reduced price.

In Europe, 80% of organic waste is incinerated even though it represents 50% of our trash. Based on this observation, three civil engineers, Adélaïde Biebuyck, Laetitia Dupret and Fiona Milano, decided to take up the challenge of developing Greenzy, an indoor composter for households, in order to help as many people as possible to recover their organic waste. 

"Our objective with Greenzy is to put technology at the service of the environment in order to facilitate everyday gestures and help households in the ecological transition" explains Laetitia. The project started as part of their studies at UCLouvain accompanied by their engineering and bioengineering professors as well as startup experts: Startech, the Yncubator and Cap Innove. After their studies, the 3 co-founders continued the project in partnership with Quimesis (engineering company), Edmire (industrial designers specialised in eco-design) and accompanied by Start it @KBC (Belgium's largest start-up accelerator). After several prototypes, various user-centred tests carried out in several households and finally a patent application for the technology, the indoor composter is available for pre-sale on the Ulule platform until 9 December on

Composting is now easy!
Simply insert your organic waste into the Greenzy composter, turn the crank shared by the shredder and the mixer 2-3 times to obtain compost. Composting is also continuous, which allows you to continuously throw away your organic kitchen waste. This will turn into compost within two months, which you can regularly collect via the bottom of the composter.

You don't need to be a compost expert, the Greenzy app takes care of everything. It helps you to obtain a quality compost thanks to different sensors that monitor the process so that the composting is done in ideal conditions. You will receive a notification explaining, for example, that you should add a glass of water if the compost is too dry. The content is therefore fun and educational, both for young children and for the whole family. 

The Greenzy composter is eco-designed and produced in Belgium. " We wanted to go all the way, from the idea to the production, so that our product would be as sustainable as possible," explains Adelaide.

With Greenzy, no more bad smells, flies or other insects in the kitchen. All this without worms to deal with!

Pre-orders are now open on Ulule!
The Greenzy composter is available for pre-order on the crowdfunding platform Ulule during the month of November up to and including December 9. Pre-orders will enable the startup to launch and finance the first production run of the composter, and then start selling direct. You can pre-order today at
