Hong Kong-based biofuels firm Ecoceres, backed by Bain Capital, has signed an investment letter of intent with the southern Chinese city of Dongguan to build the first complete supply chain for sustainable aviation fuel in the Greater Bay Area. The new facility is expected to produce a total of around 450,000 tons annually of sustainable aviation fuel and hydrotreated vegetable oil. The deal positions Hong Kong and Dongguan as a coordinated low-carbon fuels hub at a moment when global aviation faces tightening decarbonisation requirements.

 

The End-to-End Production Model

 

The Hong Kong and Dongguan partnership is designed as an integrated end-to-end model rather than a standalone refinery investment. Waste-based feedstock will be collected across China's Greater Bay Area, refining and production will be concentrated at the Dongguan facility, and blending, refuelling and trading operations will run out of Hong Kong. By linking the upstream, midstream and downstream segments under a single regional structure, the partners aim to reduce logistics complexity and tighten control over feedstock quality.

This vertically integrated approach addresses one of the main constraints in scaling sustainable aviation fuel production globally, namely the difficulty of securing reliable, low-carbon feedstock at scale. Concentrating waste feedstock collection within the Greater Bay Area provides a defined catchment for inputs while reducing exposure to volatile global feedstock markets. Ecoceres described the agreement as a significant milestone in cross-regional collaboration to advance green energy development and strengthen energy independence.

Hong Kong's SAF Mandate and Policy Backdrop

 

The agreement aligns with Hong Kong's broader policy direction on sustainable aviation fuel adoption and green technology cooperation with mainland China. The Hong Kong government last year committed to collaborate with mainland authorities to accelerate the adoption of green technologies and foster an industrial chain to support them. The new SAF supply chain operationalises that commitment by combining mainland refining capacity with Hong Kong's role as a regional aviation and trading hub.

Hong Kong has also set a target requiring departing flights from its airport to use a specified proportion of sustainable aviation fuel by 2030. That mandate creates a direct domestic offtake market for SAF produced through the new value chain, reducing reliance on overseas demand alone. The combination of policy support and a defined local market underpins the commercial logic of investing in dedicated production capacity in the region.

 

Ecoceres Background and Investor Base

 

Ecoceres was incubated by Hong Kong's city gas company Towngas in 2008 and became a Bain Capital portfolio company in 2022, which significantly expanded its capital base for international growth. The firm currently operates plants in Zhangjiagang in China and Johor Bahru in Malaysia, giving it an established footprint across multiple Asian production hubs. The Dongguan project extends that footprint into the Greater Bay Area and provides a strategic anchor close to one of the region's largest aviation markets.

The company won Chinese government export quotas last year as China began formally regulating its nascent sustainable aviation fuel market. Securing export allocations has allowed Ecoceres to participate in international compliance markets where SAF mandates are already in force. This regulatory access has been a critical enabler of the company's commercial trajectory and provides a template for managing emerging quota systems as they expand.

Export Demand and Market Dynamics

 

According to Kpler ship-tracking data, Ecoceres is shipping most of its sustainable aviation fuel and hydrotreated vegetable oil output to western destinations such as Europe. Both China and Malaysia currently lack domestic SAF blending mandates, which means production from the company's existing facilities is largely directed to jurisdictions with binding requirements. This pattern reflects the broader reality of the global SAF market, where demand is driven primarily by regulatory mandates in Europe and selected North American jurisdictions.

The Dongguan facility is well positioned to serve both export markets and emerging domestic demand as Hong Kong's mandate takes effect later this decade. Dual-market optionality is increasingly important for SAF producers given the early-stage nature of regional mandate frameworks and the variability of compliance pricing across jurisdictions. As more Asian economies introduce mandates, the relative weight of regional offtake is expected to increase compared with current export-led patterns.

 

Outlook for Asian SAF Capacity

 

The Ecoceres and Dongguan agreement signals a structural shift in how Asian sustainable aviation fuel capacity is being developed, moving toward integrated supply chains anchored in regional cooperation rather than standalone export-oriented refineries. As more cities and countries implement SAF mandates, integrated models that combine feedstock collection, refining and trading are likely to become a competitive standard. Hong Kong's positioning as a trading and refuelling hub complements Dongguan's role as a production base, creating a model that other regions may seek to replicate.

Whether the project meets its 450,000-ton annual production target on schedule will depend on feedstock availability, permitting timelines and execution of the integrated supply chain across two jurisdictions. Sustained delivery would establish Ecoceres as one of the leading SAF producers in Asia and reinforce the Greater Bay Area's position in the global low-carbon aviation fuels market. Continued progress will be closely watched by airlines, airport operators and compliance buyers tracking new sources of credible SAF supply.
