Eco-Green System




Introduction of  Eco-Green System

Establish Ecosystem on Shotcrete Slope and Rock Filled Slope


Eco-Green System is an advanced-vegetation system developed from Toyo-Mulching System (TMS).  The concept of this system is to establish an ecosystem on concrete slope.  

Eco-Green System is the enhancement from TMS by adding the Eco-Bag, which is an additional bag filled with Soil-Factor.  The provision of Eco-Bag provides sufficient nutrients for both grass and ground cover to grow, while native shrubs can also be planted over the slope. 


Once the system is well-established, micro ecosystem will be created as all year round green coverage of the slope and natural inhabitants can be found.  It is a low maintenance system after the completion of establishment period.



In a closed and self regulating system -  all the energy can be recycled and materials including carbon, oxygen, nitrogen, certain minerals, and water can sustain life - the basic ecological unit is the ecosystem. An ecosystem may be as small as a tidal pool or a rotting log or as large as an ocean or a forest. 


Each ecosystem has a community of plants, animals and micro-organisms in an environment. that supplies them with raw materials for life, i.e., chemical elements and water. The living organisms are interacting among themselves and with the environment in which they live (the climate, altitude, light, water and soil characteristics, and other physical conditions of the environment).
