Project Cases

ApolloTech provides a wide range of environmental services to a large number of clients. Our long-standing customers include government agencies such as the Ministry of Environment, municipal Environmental Protection Bureaus, the Industrial Park Administration of the Ministry of Economic Affairs, and the Chemicals Administration  of the Ministry of Environment. We also work with both public and private companies, including CPC Corporation, CPDC, Taiwan Fertilizer, Taipower, and Formosa Plastics Group. Over the years, we’ve successfully completed numerous remediation projects across various sites, including operational and abandoned factories, petrochemical plants, gas stations, contaminated farmland, and waste disposal or landfill sites.

Representative Case Studies

Petroleum Hydrocarbon Remediation
Soil and Groundwater Remediation of Zone 4-2 at CPC Kaohsiung Refinery

After the shutdown of CPC's Kaohsiung refinery in November 2015, the plant was gradually dismantled. To promote industrial transformation and attract major semiconductor manufacturers such as TSMC, the Kaohsiung City Government expedited pollution remediation efforts to revitalize the land. ApolloTech was contracted in 2021 to manage the remediation of Zone 4-2. Despite challenging conditions, the project was completed within 458 calendar days, and in April 2024, we successfully announced the de-listing of the Zone 4-2 pollution control site.

Dioxins/Mercury Remediation
Remediation Project at a Decommissioned Chlor-alkali and Pentachlorophenol Plant

This chlor-alkali plant was built in 1942, followed by the establishment of a pentachlorophenol plant in 1960. The facility, covering an area of 37.1 hectares, was shut down in 1982. In its early years, improper treatment of wastewater from the mercury electrolysis cells and disposal of pentachlorophenol by-products led to complex contamination of the soil and sediments in nearby ponds, with mercury and dioxins. The high concentration and large volume of the contamination significantly increased both the cost and complexity of the remediation. ApolloTech analyzed the characteristics of these inorganic and organic pollutants, developing an innovative soil washing method, combined with an indirect thermal desorption process, to effectively reduce the overall remediation costs. This system remains operational to this day.

Petroleum Hydrocarbons Remediation
Pollution Remediation Project at HsinChu Oil Supply Center

In line with urban development plans and pollution control requirements, ApolloTech collaborated closely with the client to promptly address site contamination. Following a comprehensive pollution assessment, we excavated the contaminated soil and significantly reduced the volume of off-site disposal by employing screening and bioremediation techniques. Our use of green remediation methods - environmentally friendly bioremediation technologies - effectively lowered pollutant concentrations, enabling the treated soil to be safely backfilled on-site, supporting the goal of sustainable soil resource management.
 

Chlorinated Hydrocarbons Remediation
Remediation of a Groundwater Contaminated Site in Yongkang

This project, the Ministry of Environment’s first chlorinated solvent contamination remediation project, employed a phased and zoned remediation strategy. The initial phase focused on controlling the pollution source and containing the most heavily contaminated areas. Using a 'precision remediation' approach, ApolloTech integrated intelligent surveys, targeted injections, and resistive probing techniques. Real-time site feedback allowed for adjustments to the injection design, ensuring successful remediation within the project timeline. Over two years of post-remediation monitoring confirmed that pollutant concentrations remained below regulatory thresholds, with no signs of rebound.
