Any questions?

How come it doesn't stink?

The composting process we use is aerobic composting, i.e. in the presence of oxygen. This composting process does not emit any odours! In order to have aerobic composting, i.e. in the presence of oxygen and therefore without odours, air enters the composter via a fan. To avoid the smell of waste that has just been thrown away or a smell of undergrowth due to the compost, we have integrated a carbon filter. This filters the air coming in (to prevent odours from escaping) and going out.

The activated carbon of the odour filter must be replaced after 4-6 months and will cost between 10 and 20 euro per year. They will be available on our website but also in the shops. The carbon granules, once used, can be composted.

We also suggest that you add a scoop of potting soil (from your composter) from time to time after adding organic waste. In addition to preventing odours, the compost will provide the new organic waste with bacteria and micro-organisms that will help it to decompose! 

What to put in the composter?

All your organic waste except bones, shells and pits as they decompose very, very slowly and meat which is a carrier of disease!

But what is organic waste?
These are your vegetable and fruit peelings, food scraps, dry bread, expired food, your eggshells, but also your used tissues and paper towels, ...

Don't be afraid, even citrus fruits like lemons and oranges can be composted!

What you can't put in :
Plastic, metal, cardboard, glass...
In short, anything that does not degrade easily 😉

What comes out of the composter? In what quantity?

Our composter follows the same principle as the composting that takes place in the bottom of the garden. You will get mature compost, a good fertilizer for plants 😉 

The amount of mature compost will depend on the amount of organic waste you produce.
We estimate 1 bucket of mature compost every 3 months for 4 people using the composter. It should be taken into account that the production of organic waste varies from one family to another and that we use the average in Belgium.

Is it suitable for children?

Of course! Children will be able to understand the life cycle of organic matter, from the plate to the garden. Sorting organic waste becomes a fun family activity.
Composting is child's play with Greenzy ! 😉

We explain how it works!

They're talking about us!

A trio of civil engineers has developed an odorless composter linked to an application, making it usable even by the uninitiated. A way to feed the earth and avoid greenhouse gas emissions.

Can technology help us make better use of our organic waste? The three young designers behind Greenzy prove it can.

With a young, feminine team full of ideas, ingenuity and trendiness, we're going to tell you all about the Greenzy composter.
