The foundation of maintaining sustainable soil resources lies in research, development, and sharing of technology. With lower carbon emissions and further upgrading as research goals, the EPA worked with industry and academia to launch multiple sustainable remediation and investigation technologies on 8 November 2021.

The EPA explained that it plays the role of a soil doctor who maintains clean soil and water via nationwide investigations, determination of pollution sources, individually designed solutions, and periodic tracking of progress in pollution amelioration and prevention. The emphasis in recent years has shifted more toward precise and environmentally friendly remediation by pinpointing problems needing to be addressed. Using subsidies from the Soil and Groundwater Pollution Remediation Fund marked for research and trials in testing venues, joint efforts between industry and academia have led to success in developing sustainable, low-carbon remediation technologies and smart and precise investigation technologies. Both “sustainable and low-carbon” and “innovative and precise” are the two main features of future green technology. The six new technologies launched are as follows:

(1) Cativation cleansing, developed by National Kaohsiung Normal University, combines micrometer-grade ozone bubbles to clean up polluted soil and sediments.

 

(2) National Pingtung University of Science and Technology developed the photocatalysis system that uses optical fibers to dispel trichloro-toxins, effectively breaking down pollutants.

 

(3) National Central University came up with high-effect bio-gels and developed local dechlorinating commensal bacteria for remediation of pollution sites.

 

(4) Chaoyang University of Technology developed a method that uses a water jet cutter to successfully resolve pollution problems in geological ground layers of low permeability.

 

(5) Central Taiwan University of Science and Technology developed equipment for soil cleansing that recycles and cleans up polluted soil using hydro-vortex technology.

 

(6) National Chung Hsing University has improved a technology that combines microbial thermal screening to optimize dominant bacteria for effective bio-remediation. Furthermore, the team developed a technology for investigation, a high-definition reactive sampling device that is able to pinpoint the depth of polluted groundwater and is also reusable. Another investigation technology is a detection system researched by the team in National Yang Ming Chiao Tung University, led by Professor Liang Cheng Chang. It uses optical fibers as a grating to sense and detect all hydrological and geological characteristics of an area.

 

Other than the technologies highlighted above, there are posters, physical displays, and oral presentations at the EPA's exhibition displaying local technologies developed with industry and academia that have been commercialized, and other multiple achievements in environmental protection technologies. These advances are able to detect pollution, enhance remediation and contribute greatly to energy conservation, carbon reduction, and resource sustainability by ameliorating current pollution sites and laying the foundation for future technological development concerning soil quality in Taiwan.
