Existing acoustic barrier has only one effect of blocking noise from vehicles, and there is no other function that improves the environment. Therefore, we dedicated to create a new design and find solution. The main component of emissions are NO3-, and NH4+ , and also the components to cause acid rain. So, we use the nitrogen-fixing ability of the moss to decompose these components that causing air pollution.
Breathing Barrier has a considerable filtration capacity. In the future, air pollution problems and certain environmental afforestation will be effectively improved and the highway guardrail will be no longer just an acoustic barrier.
