How can we, as individuals living in cities, recycle our kitchen waste at home to generate humus soils?

According to NABU, around 6 million tonnes of organic waste are dumped in rubbish bins in Germany each year, and subsequently incinerated. This is a waste of a resource that is not only valuable but gaining in importance.

‘Living Ceramics’ are ceramic containers in which organic waste can be collected and recyled within a household. Its enlarged surface area allows beneficial microorganisms to flourish that ferment the waste. The containers therefore make it possible to cultivate ones’ own plant feed and repurpose it in an individual cycle.

The fermented waste can be a useful addition to any city garden; it is rich in many nutrients plants need and can, for example, feed plants in raised garden beds for long periods of time. The harvested fruits and vegetables can be eaten, and their waste re-purposed again. A simple cycle that, considering the dire state of the earth’s soil, can be seen as a model to ensure the survival of the smallest living organisms and therefore ultimately aid in our survival as well. ‘Living Ceramics’ not only gives the smallest living beings on our planet a habitat, but also reminds us of their importance.
