These waste liquids mainly come from high-tech industries such as semiconductors and optoelectronics, characterized by complex compositions and high toxicity. To address this challenge, Taiwan regularly holds resource recycling seminars, bringing together industry elites to discuss the latest treatment technologies and future development directions.

    The importance of these seminars is reflected in the following aspects:

• Promotion of technological innovation: Facilitating the exchange and promotion of advanced treatment technologies, exploring the application of AI and big data in waste treatment, and promoting the use of green chemistry in industrial production.
• Supporting industrial upgrading: Enhancing the international competitiveness of Taiwan's high-tech industries, driving the development of the environmental technology industry, and creating new employment opportunities and economic growth points.
• Improving environmental policies: Providing a scientific basis for the establishment of stricter emission standards, promoting industrial cooperation, optimizing resource recycling mechanisms, and advancing the implementation of circular economy concepts in the industry.

    The convening of such seminars not only reflects Taiwan's emphasis on environmental protection but also demonstrates the determination to collaborate in the face of technical challenges. By pooling wisdom from all sides, the seminar aims to find innovative solutions to the challenges of treating R-2501 and R-2502 waste liquids and contribute to Taiwan's sustainable development.

Characteristics and Treatment Challenges of R-2501 and R-2502 Waste Liquids

    "Understanding the characteristics of waste liquids is the first step in innovating treatment technologies; challenges and opportunities coexist." As important by-products of Taiwan's semiconductor and optoelectronics industries, the treatment of R-2501 and R-2502 waste liquids has long been a major challenge in the field of environmental protection. The characteristics and treatment difficulties of these two waste liquids mainly include:

• Complex chemical composition: Contains multiple organic solvents such as N-methyl-2-pyrrolidone (NMP), acetone, and isopropanol, common metal ion pollutants such as copper, nickel, and lead, with large pH variations, increasing the difficulty of treatment.
• High toxicity and volatility: Potentially harmful to human health and the ecological environment, volatility increases the difficulty of collection and storage, and strict control of secondary pollution is required during treatment.
• High treatment cost: Traditional treatment methods are energy-intensive and inefficient, requiring significant equipment investment, high operating costs, and low economic value of the treated by-products.

    Faced with these challenges, environmental technology companies in Taiwan have been actively seeking breakthroughs. For example, the development of multiphase catalytic oxidation technology has not only improved treatment efficiency but also significantly reduced energy consumption. However, despite some progress, the treatment of R-2501 and R-2502 waste liquids still faces many challenges:

• Technical bottlenecks: Efficient and low-consumption separation technologies need to be developed, selective removal of specific organics remains difficult, and the detection and removal of trace heavy metals in waste liquids pose significant challenges.
• Increasing environmental standards: Taiwan continuously tightens emission standards, with higher treatment effectiveness requirements, stricter demands for green production in international markets, and increased public attention to corporate environmental performance.
• Economic feasibility: The development and application costs of high-efficiency treatment technologies remain high, the reuse value of treated products needs to be improved, and small and medium-sized enterprises find it difficult to afford advanced treatment equipment.

    Experts agree that future technological development should move toward more efficient, economical, and environmentally friendly directions. This requires not only technological innovation but also policy support and collaborative efforts across the entire industrial chain.
