Tanah Sutera Development Company, with EM Research Organization as technical adviser, has developed an area of 487ha at the western corridor of Johor Bahru City.
The area is mainly divided into two regions, namely Taman Sutera and Taman Sutera Utama, and the city is constructed with its housing, school, hospital and commercial facilities.

To make the city eco-sensitive, Tanah Sutera Development put up a “5R” principle, with a concept of Green Vision, i.e., “To create a zero waste and green living environment starting with Tanah Sutera residents and expanding to our community and to the society at large”. The 5R stands for five words that start with the letter “R”, namely, Reduce, Reuse, Recycle, Rethink and Responsible. “
Reduce” means to reduce food wastes and to reduce the use of chemical fertilizers, pesticides, etc. 
“Reuse” means to reuse existing technologies and materials. 
“Recycle” means to recycle wastes into useful materials. 
“Rethink” means to rethink our consumption behaviors and old habits, thereby incorporating more green features into our design. 
“Responsible” means to be a responsible member of the community and to ensure the health and environment for us as well as for our children. 

In 2009, Johor State Government introduced the use of EM Technology to Tanah Sutera Development and they decided use EM Technology in the design of the eco city.

The excessive inflow into the ponds of the substance of concern such as phosphorus or other chemicals is liable to impair the cleaning ability of the eco-system. 
This lead to the accumulation of polluted sludge and accelerated growth of corruptive microorganisms along with the production of foul smell. In order to maintain the natural cleaning capacity inherent in eco-system, addition of EM and/or EM mudballs into the polluted site will support the increasing beneficial microorganisms in the environment.

Drainage is first poured into an oxidation pond for natural depuration. 
The water that reached the level below the predetermined reference is discharged to the river. Periodical addition of EM and/or EM mudballs is also scheduled to maintain the cleaning capability of the eco-system. 

Efforts are made to reduce the use of bleaching agents and bactericidal agents to the extent possible at the Sutera Mall. 
Application of EM is keeps beneficial microorganisms by suppressing the growth of putrid and pathogenic bacteria. 

The kitchen garbage output from standard homes or public facilities is recycled with EM Technology to be used as organic fertilizer in the field or for other plantings. 
Recycling of old newspapers and plastic (PET) bottles is being carried out as well.

Meetings for environmental education are organized periodically at school or in local community to nurture the sound attitude towards nature, life and environment.
Tanah Sutera provides opportunities for learning the basic knowledge and efficient application of EM Technology.

The efforts and trials to create an eco-city have been highly evaluated by the State Government.
Tanah Sutera Development Company won the Green Award Competition 2013 sponsored by the Johor State Government in conjunction with the State Environmental Awareness Campaign and Earth Hour 2013
