PTTLNG: Harmonizing Industry with Nature | TK STUDIO

Winner of the Outstanding Award in the 2025 WLA Awards

PTTLNG has constructed a receiving terminal along the shoreline of Nong Fab, near Rayong’s industrial estate. The 21.6-hectare site is used for LNG transfer, storage, and regasification, while an additional 8.1 hectares is designated for the office zone.

As part of PTTLNG’s commitment to becoming an environmentally friendly organization, the project integrates sustainable solutions to minimize its impact on nature. The office zone was originally a degraded swamp, which had been filled and leveled. As a result, Fab, the dominant native plant that once thrived in this area, became endangered. To mitigate this, the remaining swamp was preserved by strategically placing all hardscape areas and office buildings on higher ground. To restore the ecosystem, the remaining swamp was excavated into a retention pond with a riparian edge, designed to regenerate Fab and reintroduce biodiversity.

Sustainable Landscape Design

The landscape design of the office zone prioritizes nature-based solutions to mitigate waste and environmental impact while fostering a healthy and sustainable working environment.

To achieve this, a reverse waste management system was implemented. Instead of discharging waste and excess water directly into the sea, the system captures, treats, and reuses resources within the office zone. Specifically:

  • Runoff from both the operation and office zones is collected and filtered through bio-swales before being stored in the retention pond for irrigation.
  • The retention pond not only supports stormwater management but also serves as a habitat restoration area.
  • A surrounding eco-forest was created to restore native plant species and support carbon sequestration.

The regasification process of LNG produces excess chilled air (5°C), which is typically released into the sea as chilled water. Instead, this cooled air is repurposed for building cooling systems and to create a temperate climatic dome for flowering displays.

A MultiFunctional, EcoFriendly Space

  • The detention lawn behind the main building, was designed as a multi-purpose recreational space for staff while also serving as a stormwater management feature, prolonging runoff absorption during the rainy season.
  • The green roof enhances rainwater retention, provides thermal insulation forthe building, and supports native grass species, offering additional habitat for wildlife.
  • Portions of this office zone are open to the public, including some indoor areas and outdoor nature trails, forming an educational loop provide educational opportunities about energy, environmental conservation, and local ecology.
  • The temperate flower dome, made possible by repurposed chilled air, serves as an attraction for local, showcasing diverse flowering plants.

A Model for an EcoFriendly Industry

After five years of development, nature has been gradually restored. The once-endangered Fab plant is thriving again, alongside various native species. PTTLNG has become an unexpected tourist attraction in Rayong—which rarely seen in Thailand’s industrial sector.

As part of its long-term vision, PTTLNG strives to be a leader in sustainable development, proving that industry and nature can coexist harmoniously. It demonstrates how industries can contribute to a nature-positive economy, ensuring that economic progress and environmental conservation move forward together to enhance both our quality of life and the health of our planet.
