The Future Implication of The Future Implication of CLEANTECHCLEANTECH

The potential implication of cleantech include:Zero energy approachDe-materialization of ProductionZero emission

A combination of above with resource recycling and co-generation could lead to positive environmental impact

Implication for Indian Industry

The self repaying low cost innovation based approach would provide instant opportunity for enviro-management to Indian Industry to beyond compliance levels, simultaneously enhancing their ability to compete globally. This would also unlock the investment potential of Indian Industry for Environment.
