KoirTray™ is also used as a natural, biodegradable modular system for vegetated roofs. These modules are usually square trays. Unlike traditional modular systems, the coconut fiber decomposes over time, and the KoirTray™ module is converted into humus. This eliminates the use of plastic materials in
growing and installing vegetated roofs, increasing the sustain ability of the roof. There are added benefits to overall LEED score as well.
