How do Living Walls work as a biofilter?
Nature has the built-in capacity to adjust to environmental changes. It can repair itself after damage or adapt to exposure from a wide range of compounds. Although the time scale may vary from minutes to centuries, in time a natural ecosystem can repair almost any damage it may sustain. For example, given enough time nature can restore a site contaminated with organic compounds such as VOCs. One reason for this is that, frequently, materials such as VOCs that are toxic to some life are food for others. Most of the biological breakdown of VOCs is done by microbes (bacteria), although higher plants may also be involved. Some pollutant-degrading species are usually present and active in most environments, and the act of introducing the pollutant only increases their relative numbers and/or activity levels. NEDLAW active Living Walls are a biofilter containing such organisms to remove contaminants present in the air at very low concentrations. In essence, we mimic indoors what happens out
