Recycling and Reuse

In a resource-constrained environment, ECOVE firmly believes that the circular economy model is the most sustainable approach. Therefore, we leverage our core operational expertise to avoid pollution and waste generation from the source through redesign, business models, and improved resource efficiency. We aim to create more value with fewer resources, while aligning with government sustainable development policies and promoting waste resource utilization towards a circular economy society.

IPA Recycling and Reuse

To maximize the value of waste resources, ECOVE extends the application of recycling and reuse technologies through its subsidiary, ECOVE Solvent Recycling Corp., specifically targeting the purification and conversion of waste isopropyl alcohol (IPA) generated in the semiconductor industry. The purified IPA is transformed into industrial-grade products and reintroduced to the market, effectively reducing resource waste. In 2022, ECOVE Solvent Recycling Corp. processed approximately 14,710 metric tons of waste isopropyl alcohol, an increase of 3,610 metric tons compared to the previous year. This resulted in a reduction of 10,841 metric tons of carbon dioxide emissions annually.

Recycled water treatment

ECOVE's core operations in the water resources field encompass wastewater treatment, rivers and streams restoration, and water resource regeneration. Various methods, including primary treatment, secondary treatment, advanced treatment, and ecological methods, are utilized to remove pollutants from water and further recycle and reuse water resources. To ensure real-time monitoring of discharged water quality, automated continuous monitoring systems are installed in the water plants. This enables the monitoring of trends in discharged water quality and facilitates access for relevant authorities and the public to query the data.
▼ Developmental works in water resources and expected technical performance

ECOVE is not only committed to environmental protection in its operational and maintenance efforts but also focuses on maximizing resource value and promoting sustainability. In 2022, ECOVE 's water resource recycle centers in Linkou, Zhonggang, and the purification facility in New Taipei City, as well as the water resource treatment facility in Pingtung Agricultural Biotechnology Park, collectively processed 26,851,116 metric tons of sewage. Additionally, a cumulative total of 41,091 metric tons of treated effluent (from Linkou water resource center only) were recovered and made available for internal and external use. Based on the estimation criteria outlined in the Ministry of the Interior's "Technical Standards for Building Wastewater Treatment Facilities," ECOVE's efforts and achievements in wastewater treatment and water resource reuse are equivalent to serving 119,340,000 person-days. This is equivalent to treating the sewage output of the national population for nearly 5.1 days. The amount of water recycled is also equivalent to the daily water consumption of 183,000 individuals. In addition to treating wastewater, we provide clean water resources as an alternative water source, equivalent to the daily water consumption of nearly 183,000 individuals, thus continuously enhancing the sustainability of water resources.

Recycling of PET bottles

BoReTech Co., Limited is a subsidiary of ECOVE's investment company, providing comprehensive PET bottle recycling and regeneration solutions to customers. We offer end-to-end integration of the recycling industry chain, including production line design, engineering, bottle washing, pelletizing, and chemical fiber spinning. This vertical integration significantly reduces production costs of PET bottle recycling and cleaning equipment, minimizes losses during production, and improves the quality of the final products. In 2022, the "ES Process"❸ was successfully applied to the PET bottle recycling and cleaning system. By integrating label removal with bottle washing into a unified module, it assists customers in significantly reducing equipment footprint and further enhancing the efficiency of label removal. We also collaborated with customers to develop a compact integrated fishing net recycling and cleaning system, contributing to marine conservation efforts. Furthermore, we developed cleaning processes for rigid plastic and film recycling systems, aiming to expand the product scope of plastic recycling and make a greater contribution to global plastic recycling as a whole.
