Demonstrating Net Zero Execution and Fulfilling Our Commitment to a Sustainable Planet

ECOVE Environment Corporation Chairman J.J. Liao (提供總裁簽名檔)

This year marks the 10th anniversary of the Paris Agreement entering into force. In the face of the severe challenges posed by climate change, translating carbon reduction commitments into concrete action and achieving the goal of limiting global warming to within 1.5℃ require all sectors to move toward the next milestone with stronger execution. As the most trusted practitioner of sustainable Resource Cycling, ECOVE has implemented the circular economy concept with solid execution since its founding. Our long-term efforts
have earned international recognition: ECOVE was selected for the 2025 S&P Global Sustainability Yearbook and named an Industry Mover; domestically, we were also recognized with third place in the Medium-sized Enterprise category of CommonWealth Magazine's Corporate Citizenship Awards. These achievements are the best proof of ECOVE's outstanding execution capabilities and Net Zero implementation.
　

Advancing Energy and Resource Management to Build a Low-carbon Circular Model

ECOVE has long maintained a leading position in energy and resource management in Taiwan, and is the only operator in Taiwan that provides integrated services spanning waste collection and transportation, Energyfrom-Waste (EfW) conversion, and downstream disposal. We currently operate 11 large Energy-from-Waste Centers, accounting for more than half of the treatment volume among privately operated centers in Taiwan. In 2025, we treated approximately 2.9 million metric tons of waste, generated 1.62 billion kWh of electricity, and reduced carbon emissions by approximately 790,000 metric tons. In business expansion, the Taoyuan Biomass Center has officially commenced operations, while the Chiayi City Green Energy Sustainable Recycling Center BOT project is aligned with international standards and designed with an energy recovery rate of up to 27%. Recently, ECOVE also secured the future 20-year Rehabilitate-Operate-Transfer (ROT) project for the Keelung Energy-from-Waste Center and the operation contract for the Houli Energy-from-Waste Center.
　
Through the continuous introduction of digital and data management systems, operational eciency continues to improve. At the Taitung Energy-from-Waste Center, for example, after ECOVE took over operations, the team substantially optimized performance and increased single-furnace treatment capacity by approximately 33%, earning strong recognition from the owner. Looking ahead, as contracts for multiple domestic Energy-from-Waste Centers expire, ECOVE will leverage its extensive rectification and operating track record, together with the Group's plant construction experience, to actively pursue BOT projects as well as service-life extension and upgrade opportunities. At the same time, we will continue expanding in overseas markets such as Southeast Asia and India to co-create new circular economy value with local partners.
　

Expanding Renewable Energy to Drive Green Transformation

Amid the global wave of energy transition, ECOVE is actively expanding solar power services and is one of the few domestic providers offering integrated services from development, investment, construction, and operation to green power transactions. At present, ECOVE holds a total installed capacity of approximately 148 MW across domestic and overseas sites, and manages and maintains a total capacity of 485 MW. To address the intermittent nature of renewable energy, we have introduced integrated solar, charging, and storage solutions to help owners build smart, low-carbon sites.
　
In electricity sales, in response to corporate RE100 green power commitments and major electricity user requirements, we have successfully signed 42 MW of green power resupply contracts. In addition, self-consumption solar power systems at Energy-from-Waste Centers have been officially connected to the grid and commenced commercial operation, steadily generating 300 green power certificates each year and enhancing the diversity of our green power services. Going forward, we will combine Group advantages with close attention to policy opportunities such as the U.S. Inflation Reduction Act, actively develop overseas standalone energy storage sites, and expand our green energy footprint.
　

Deepening Recycling and Reuse to Realize Zero Waste Goals

ECOVE is committed to helping the high-tech industry deepen recycling and reuse and implement Resource Recycling & Zero Waste. In waste solvents, we use innovative technologies to raise the purity of waste isopropyl alcohol (IPA) to 99.9% for re-entry into the market, while continuing to develop electronic-grade reuse technologies. Currently, we recycle approximately 14,000 metric tons of waste solvents each year and support in-plant recycling of approximately 3,400 metric tons at semiconductor facilities. We will also continue investing in waste sulfuric acid reuse for the high-tech industry. In water resource resilience, our services have expanded to reclaimed water and seawater desalination: the Tainan Science Park Reclaimed Water Plant, with cumulative reclaimed water output of 56 million metric tons, is the world's first facility to reclaim industrial wastewater for reuse in semiconductor processes. The Hsinchu Seawater Desalination Plant, scheduled to commence operation in 2028 with daily output of 100,000 metric tons, will further support a win-win outcome for the environment and the economy.
　

Deepening System Facility Services to Extend Asset Life

Extending asset life is central to ECOVE's implementation of the circular economy. Leveraging deep electromechanical expertise, we provide professional maintenance and performance improvement services for transportation stations, high-tech plants, and Energy-from-Waste Centers. In transportation facilities, we perform maintenance for metro systems, light rail systems, and airport boarding bridges. For Energy-from-Waste Centers, equipment renewal and technology upgrades have enabled us to successfully help facilities such as the Kaohsiung Central, Southern, and Gangshan plants, as well as the Changhua Xizhou plant, extend service life and reduce resource consumption. In particular, the energy-saving improvements at the Gangshan plant have successfully obtained registration approval from the Ministry of Environment for a voluntary reduction project, with an approved quota of 3,830 metric tons, transforming green technology into carbon credit assets.
　

ESG for All Employees: Continuously Advancing Corporate Sustainability

ECOVE has deeply cultivated an ESG culture. According to the latest 2025 survey, employee recognition of ESG has increased to 91%. Our outstanding sustainability performance has earned us a Top 5% ranking in the Corporate Governance Evaluation for 12 consecutive years and third place in the Medium-sized Enterprise category of CommonWealth Magazine's Corporate Citizenship Awards. In employee care, we are committed to promoting work-family balance. In addition to increasing childbirth subsidies, we have introduced family care leave and childcare subsidies to create a happy workplace. In carbon management, we have established internal carbon pricing at US$100 per metric ton, actively obtained self-consumption green power certificates, and passed registration for a voluntary reduction project. We will continue fulfilling our environmental commitments through concrete action and work with customers to co-create a sustainable future for the planet.
