The column that growsthe city...and nature

A mube green column is an autonomous and innovative structure, designed to reintroduce biodiversity into the city while serving as a support for the smart city. It combines a compact design (less than 1 m² footprint) with measurable ecological performance (depollution, cooling, attractiveness).

The standard column measures 6 m high with a diameter of approximately 70 cm (including plants). It can be adapted from 4 m to 9 m depending on requirements.

The column is a self-contained object, with its own structure and foundations. It also comes in a self-stable version with a base that can serve as seating.

Depending on the site, from 1 day to 1 week.

A foundation comparable to that of a lamppost is generally required. For temporary or modular installations, we offer a self-supporting version.

Required maintenance is very limited:

• Automated and smart irrigation thanks to sensors,
• 2 to 4 annual visits for pruning and plant monitoring.

We recommend renewal every 5 years to regenerate the substrate and maintain optimal plant coverage.

Each column is equivalent to approximately 15 m² of vegetation, which is the equivalent of a 5 m tree.
Plants absorb CO₂, CO, NOx, and fine particles and release oxygen.

Yes. Through evapotranspiration, heat absorption, and the creation of microclimates, the column reduces urban heat island effects and locally regulates temperature.

A scientific experiment is underway with INRAE to quantify the exact impact on air quality and urban temperature.

Absolutely. Unlike traditional planting where 50% of water is lost, the columns’ closed system optimizes irrigation: 100% of the water is used by the plants, leading to water savings. This patented irrigation allows for up to 70% water savings per year, thanks to smart watering.

Over 200 columns, of various sizes, have already been installed in France and Europe.

About twenty varied species: melliferous plants, aromatics, grasses, perennials. The column remains green all year round thanks to a selection of evergreen species.

No. No mosquitoes (absence of stagnant water), no wasps/hornets (absence of fruit). Bees forage at height, posing no risk to pedestrians. We prioritize non-allergenic plants.

• For local authorities: to improve quality of life, enhance the attractiveness of public spaces, and address ecological transition challenges.
• For industrial companies: to integrate visible and measurable environmental compensation solutions, strengthen brand image, and improve project acceptability.
• For cities: to promote an innovative, inspiring, and scientifically monitored project.

We support our partners with:

• The design and adaptation of the system,
• Scientific and ecological monitoring,
• Communication and impact assessment.
