Yongkang Water Reclamation Plant

Taiwan's first high-tech industrial water reclamation plant

Project Type: Design-Build-Operate (DBO)
Treatment Capacity: 87,000 CMD design capacity for wastewater treatment. Phase I operational: 29,000 CMD wastewater treatment. Reclaimed water supply: 8,000 CMD (2022) expanded to 15,500 CMD (2024)
Service Period: 2022-2037
Client: Tainan City Water Resources Bureau

Project Overview:

Facing intensifying water scarcity and climate challenges in southern Taiwan, the Yongkang Water Reclamation Center represents a transformative solution for sustainable water management. As Taiwan’s first facility dedicated to supplying reclaimed water to high-tech industries, we’ve created a reliable secondary water source that reduces competition between industrial and residential water needs.

Pioneering Water Reuse: Every Drop Counts Twice

Our facility transforms municipal wastewater into industrial-grade reclaimed water, establishing a sustainable water cycle that serves both environmental protection and economic development.

Award-Winning Operational Excellence

  • Gold-certified Green Building & Qualified Smart Building (2023)
  • Double “Excellence” ratings in National Wastewater Treatment & Reclaimed Water Infrastructure Evaluations (2024)
  • Environmental Protection Administration’s “Sustainable Water Award”
  • Ministry of Interior’s “Outstanding Smart Building Achievement”

Advanced Treatment Integration

Our multi-barrier treatment system combines A²O+MBR, single-pass two-stage RO, and advanced phosphorus removal to consistently exceed reclaimed water standards (BOD≤20 mg/L, SS≤20 mg/L, TN≤15 mg/L, TP≤2.0 mg/L), while maintaining environmental discharge requirements.

Waipu Bioenergy Plant

Taiwan's first food waste anaerobic digestion plant

Project Type: Anaerobic Digestion / Renewable Energy Generation
Processing Capacity: 30,000 tons food waste annually / 3 million kWh green electricity
Service Period: 2017-2042
Client: Taichung City Environmental Protection Bureau

Project Overview:

Through a ROT partnership with Taichung City Government, Heshan Forest Green Energy transformed the Waipu facility into Taiwan’s pioneering food waste-to-energy plant. Our anaerobic digestion system converts organic waste into biogas for electricity generation, while digestate byproducts support agricultural applications—exemplifying circular economy principles in action.

Six Years of Proven Performance:

  • 130,000 tons of food waste processed
  • 14.5 million kWh of green electricity generated
  • 7,000 tons of CO₂ emissions reduced

Recognition & Impact:

  • Resource Recycling Excellence Silver Award
  • Asia-Pacific Sustainability Action Award
  • Environmental Education Facility Certification
  • Green Building Certification
  • 150+ educational programs delivered to 5,000+ participants

From Waste to Resource

Our facility demonstrates how innovative technology transforms environmental challenges into renewable energy opportunities. By converting food waste into clean energy and agricultural resources, we’re closing the loop on organic waste while contributing to Taiwan’s renewable energy targets.

Educational Hub for Sustainability

Beyond operations, the facility serves as a living laboratory for circular economy education, inspiring communities to reimagine waste as a valuable resource.

Reuse Environmental

Incineration bottom slag treatment

Project Type: Municipal Solid Waste Bottom Ash Processing
Processing Capacity: 41,200 tons/month permitted capacity
Clients: County/City Environmental Protection Bureaus

Project Overview:

Since joining Mountain Forest Water Group in November 2017, Li You Shi Environmental has become Taiwan’s largest bottom ash processing facility by both permitted and actual processing volume. We transform incineration bottom ash into valuable recycled aggregates, demonstrating how waste becomes resource through innovative processing technology.

Industry Leadership & Recognition:

  • National #1 in processing capacity and volume
  • Two-Star Excellence Rating – EPA’s highest circular economy certification
  • National Enterprise Environmental Protection Award nominee
  • Environmental Label Certification for recycled aggregate products

2024 Performance Highlights:

  • 276,000 tons processed – record annual volume
  • Operations across Kaohsiung, Pingtung, Chiayi, Taitung, and Penghu
  • New Luzhu facility operational (December 2024) – 230,000 tons annual capacity

Pioneering Wet Processing Technology

As Asia’s first adopter of full-scale wet bottom ash processing, every particle undergoes water washing to remove organics and heavy metals, producing aggregates that are “clean, odorless, and non-toxic.”

Circular Economy Applications:

Our recycled aggregates serve diverse infrastructure needs:

  • Road base and sub-base materials
  • Controlled low-strength materials (CLSM)
  • Pervious concrete applications
  • Concrete products (barriers, curbs, bricks)
  • Construction fill materials
  • Landfill daily cover

Environmental Impact:

By converting waste to resource, we:

  • Reduce natural aggregate mining
  • Lower transportation-related carbon emissions
  • Support public infrastructure projects with sustainable materials
  • Advance Taiwan’s 2050 net-zero transition goals

Future Vision:

Building on our “Innovation, Expertise, Quality, Service” principles, we continue expanding capacity while advancing ESG objectives. Our commitment to resource circulation drives continuous investment in technology and process optimization, establishing new standards for waste valorization in Taiwan and beyond.
