The water pollution in the nature is becoming more serious. To stop the water pollution, both micro-organism and bioremediation are in the limelight of construction materials. In addition, plants have so many advantage of vegetation, energy conservation, and water purification. Green (and/or Eco-Friendly) building materials of Eco-concrete and vegetation bricks have increased in human demand. In this study, combining the two elements can be utilized in the construction materials. Excellent performance in the treatment of wastewater microbial decomposition is applied to the moss brick. Green Building materials we investigated as a potential resources.
