Geoenvironmental and geoecological integrated technology (GGIT) is a cost-effective and environment-friendly technology that encompasses the applications of earth science principles and functions of geological environment and ecosystems to assimilate and minimize the spread of pollutants, to enhance the sorption capacity and environmental remediation. On the basis of the integrated approaches such as system, anthropogenic activities - ecosystem - environment interaction, effectiveness and feasibility, GGIT has provided significant applications in Vietnam such as waste containment and remediation and environmental protection. The results of a pilot scale using iron mine drainage sludge and common reed (Phragmites australis) for wastewater treatment in a Pb-Zn mine in northern Vietnam indicated the effective and potential application of GGIT. However, GGIT has many challenges in limited funding conditions, constraints in the initial development of GGIT, incomplete transfer to users, and quantitative assessment of pollutant cleanup by natural environments and ecosystems. Environmental pollution quote, impacts to exposed organisms, increasing demands for application of low-cost technologies, the availability of potential sorbents, indigenous plants, and ecosystems for environmental remediation, and collaboration will promote development, contribution, and implementation of GGIT applications in Vietnam.
