A London startup is developing moss-covered panels for city walls to create living infrastructure that cleans air and dampens noise [1, 2].

This initiative addresses the critical need for sustainable urban planning in dense environments. By integrating biological filters directly into building exteriors, the project seeks to combat the systemic pollution and noise levels common in major metropolitan areas.

The cladding system consists of panels covered in moss, designed to be installed on existing city walls [1, 2]. These living walls function as a natural filtration system, absorbing pollutants from the atmosphere, and adding greenery to the concrete landscape [1, 2].

Beyond air quality, the startup designed the panels to mitigate noise pollution [1, 2]. The organic material of the moss acts as a sound buffer—reducing the echo and roar of city traffic—which can improve the overall quality of life for residents and pedestrians [1, 2].

The project aims to increase human exposure to nature within the city [1, 2]. Urban greenery is often limited to parks, but this cladding approach allows nature to occupy vertical spaces that were previously unused [1, 2].

This development comes as cities worldwide search for scalable ways to meet environmental targets. The use of moss is particularly effective because it requires fewer resources than traditional vertical gardens while providing significant ecological benefits [1, 2].

The transition toward 'living infrastructure' represents a shift from passive green spaces to active biological tools. If scalable, moss-based cladding could allow cities to utilize vertical real estate to offset carbon emissions and noise without the need for land-intensive parks.
