The aponix living WallSystem that provides a very modular solution to plant and maintain walls easier and more robust compared to most of the felt-based living wall systems that become hard to clean and maintain over time and just look fancy after they have been installed or when the expo opens. I took a deeper look into such existing systems and found that there is a long list of properties that needed to be integrated plus the modularity and variability typical for aponix engineering.

There are many underutilized areas in in urban spaces. Roof top greening has been a big topic for some years now. Wall applications usually used felt based systems that are not long therm or one for certain climates or situations. Plantable wall systems are needed that are component based, robust and versatile that can be integral part of buildings and social processed longer term.

Add more biodiversity, retain stormwater and put it to a second use, green indoor and outdoor unused fences and walls, integrate maintenance into the urban social processes, create a better climate through evapotranspiration etc etc.
