In late October, Hong Kong once again opened its harbour-side convention halls to the question that now shapes so many economies: how a place can grow without spending its future. The 21st Eco Expo Asia, gathering more than 340 exhibitors from fifteen countries and regions at AsiaWorld-Expo, carries that question under the banner of connecting the world toward a sustainable future. Its significance lies as much in the bridges it builds as in the technologies it displays, for Hong Kong here presents itself as a meeting point between Mainland ambition, Belt and Road partners and Southeast Asian
21st Eco Expo Asia Opens in Hong Kong With 340+ Exhibitors and Belt and Road Green Focus
The one concrete outcome is a memorandum of understanding signed last year
Mark
Why does this expo matter beyond being a trade show?
Mimi
It's where Hong Kong's policy language gets tested. The first Five-Year Plan and Policy Address set green priorities, and here are firms trying to sell into them.
Mark
What's new this year?
Mimi
An ASEAN Pavilion with seven countries, five nations attending for the first time, Qinghai's debut, and a GoGlobal Connect Zone for Mainland firms heading abroad.
Luke
Careful with the framing, though. Most of this is the organisers describing their own event. The 340 exhibitors and 80 leaders are their figures.
Mark
So nothing independent on results?
Luke
Right. The one concrete outcome is Lihe Technology's memorandum of understanding with a Kazakhstan delegation last year. An MoU isn't a contract, and we don't know what followed.
Mimi
Still, the product range is specific: waste-derived aviation fuel, tea-waste films, carbon observation from a space station.
Luke
Specific, yes, but those product claims are exhibitors' own descriptions. Nothing here tests them.
Mark
What should I watch?
Mimi
The GoGlobal Seminar on ASEAN expansion and the Hydrogen Economy Forum, where policy meets procurement.
El Pulso
- Over 340 exhibitors from 15 countries and regions crowd the four-day floor, turning a green policy agenda into a crowded marketplace of ideas.
- The first-ever Belt and Road Green Innovation Conference, held jointly with the Ministry of Ecology and Environment, pushes the Expo beyond display into official dialogue.
- Five Southeast Asian nations join for the first time, and a new ASEAN Pavilion places twelve green ventures in direct contact with buyers and partners.
- A GoGlobal Connect Zone and seminar on ASEAN expansion aim to guide Mainland firms through green finance, certification and industrial park partnerships abroad.
- With a Public Day on 29 October offering free admission, the Expo opens its doors beyond officials and investors to the wider city.
In late October, Hong Kong once again opened its harbour-side convention halls to the question that now shapes so many economies: how a place can grow without spending its future. The 21st Eco Expo Asia, gathering more than 340 exhibitors from fifteen countries and regions at AsiaWorld-Expo, carries that question under the banner of connecting the world toward a sustainable future. Its significance lies as much in the bridges it builds as in the technologies it displays, for Hong Kong here presents itself as a meeting point between Mainland ambition, Belt and Road partners and Southeast Asian markets seeking greener footing.
The 21st Eco Expo Asia opened on 26 October at AsiaWorld-Expo, running through 29 October under the theme 'Connecting the World for a Sustainable Future'. Over 340 exhibitors from fifteen countries and regions are taking part, and about 200 senior officials and representatives of semi-official bodies from the Mainland, Hong Kong, Belt and Road countries and ASEAN are expected. The Hong Kong Trade Development Council and Messe Frankfurt (HK) organise the event with the HKSAR Government's Environment and Ecology Bureau, and the city's leaders frame it as part of Hong Kong's first Five-Year Plan and the nation's 15th Five-Year Plan, positioning the city as a 'super connector' and 'super value-adder' for green growth.
The Expo has grown to eighteen pavilions. Indonesia, Laos, the Philippines, Thailand and Vietnam take part for the first time in a new ASEAN Pavilion, while Qinghai Province debuts alongside Greater Bay Area cities and several other Mainland regions. Local players bring start-ups in energy, environmental campaigns and science parks, and the government booth introduces an experience zone organised around Green Flat, Green Match, Green Cooperation and Green Innovation.
A parallel thread concerns Mainland firms moving abroad. The HKTDC has opened a GoGlobal Connect Zone for the first time, and an opening-day forum featured Hunan exhibitor Lihe Technology, which had signed a memorandum with a Kazakhstan delegation at last year's Expo. A seminar on 27 October will bring Malaysian and Thai industrial park representatives together with Bank of China (Hong Kong) and the Hong Kong Accreditation Service to discuss how firms might enter ASEAN.
On the floor, exhibits range from sustainable aviation fuel and fast EV charging to tea-waste packaging, AIoT fleet management and waste-to-energy projects. Over thirty forums follow, including a hydrogen economy forum on 28 October and a Public Day on 29 October with free admission.
The 21st Eco Expo Asia opened on 26 October at AsiaWorld-Expo in Hong Kong, running four days through 29 October under the theme 'Connecting the World for a Sustainable Future'. More than 340 exhibitors from 15 countries and regions are taking part. About 200 senior officials and representatives of semi-official organisations from the Chinese Mainland, Hong Kong, Belt and Road countries and ASEAN are expected to attend.
The Hong Kong Trade Development Council and Messe Frankfurt (HK) Ltd jointly organise the event, with the Environment and Ecology Bureau of the HKSAR Government as co-organiser. HKTDC Executive Director Sophia Chong tied it to Hong Kong's first Five-Year Plan and the latest Policy Address, both of which call for a green and liveable city. She noted that Indonesia, Laos, the Philippines, Thailand and Vietnam are participating for the first time. Tse Chin-wan, Secretary for Environment and Ecology, said the city's plan aligns with the nation's 15th Five-Year Plan and that Hong Kong will use its roles as a 'super connector' and 'super value-adder'. For the first time, his bureau and the Ministry of Ecology and Environment are holding the Belt and Road Green Innovation Conference in Hong Kong on 26 October, alongside the Expo. A welcome ceremony follows on 27 October, with Tse, Chong and Jack Wong, Deputy General Manager of Messe Frankfurt (HK), among the guests.
Pavilions have grown to 18. A new ASEAN Pavilion brings together Singapore, Laos, Malaysia, the Philippines, Indonesia, Thailand and Vietnam, with 12 green technology ventures working in water treatment, circular economy, green finance and ESG services, green building and environmental products. Canada, Italy, Korea and the Netherlands return. Qinghai Province appears for the first time, joined by nine Greater Bay Area cities, Macau, Guangxi, Hunan, Shanghai and Nanjing. Locally, the Hong Kong Science and Technology Parks Corporation leads 11 start-ups showing energy solutions, the Hong Kong Pavilion gathers 19 companies, and the Environmental Campaign Committee brings 22 start-ups. The HKSAR Government booth, run by the Environment and Ecology Bureau, the Environmental Protection Department and nine other departments, debuts an experience zone built around four themes: Green Flat, Green Match, Green Cooperation and Green Innovation.
A second thread is helping Mainland firms expand abroad. As a member of the GoGlobal Task Force, the HKTDC has opened a GoGlobal Connect Zone for the first time. On opening day an Experience Sharing Forum on overseas environmental business featured Hunan exhibitor Lihe Technology, which signed a memorandum of understanding with a Kazakhstan delegation at last year's Expo. Officials from Belt and Road countries, InvestHK and Mainland firms joined, followed by an ASEAN networking reception. On 27 October a GoGlobal Seminar brings industrial park representatives from Malaysia and Thailand together with the Bank of China (Hong Kong) and the Hong Kong Accreditation Service to discuss green finance, infrastructure expertise, certification standards and park partnerships for entering ASEAN.
The exhibition floor is organised around four areas reflecting policy: Green Energy in Motion, Frontier Green Tech, Building for a Greener City and From Waste to Worth. The State Council issued its action plan for carbon peaking during the 15th Five-Year Plan period in July, and Policy Address 2026 sets measures on zero-carbon energy, hydrogen, green transport and waste reduction. EcoCeres, described as the world's second largest sustainable aviation fuel producer, debuts with SAF and HVO made from waste feedstocks. TriTerra Technology shows what is billed as the slimmest wall-mounted DC fast EV charger on the market. Chinese University of Hong Kong presents bacterial cellulose films made from tea waste, for packaging or bio-based leather, and Lingnan University shows a fleet management system combining AIoT and GeoAI. Hyper-Tech Environmental shows the Oizom monitoring system, Umwelt Consulting shows acoustic windows and balconies, Chongqing Sanfeng Environment Group presents waste-to-energy projects in the Mainland and 10 other countries, and Baguio Green Technology shows a smart waste management system.
More than 30 forums and sessions draw over 80 officials and industry leaders from the Mainland, Australia, Malaysia, Thailand and other Belt and Road countries. On opening day, HKUST's Prof Su Hui described the Multi-Spectral Imaging Carbon Observatory, installed on China's Tiangong Space Station this year, and joined CityUHK's Prof Kenneth Leung to discuss extreme climate monitoring. On 27 October come the Eco Asia Conference government session, a Green Silk Road panel, a Government Department Forum on procurement needs and the Startup Edge Exhibitor Forum. The 7th Hydrogen Economy Forum is on 28 October, with a keynote by Eddie Cheung, Permanent Secretary for Environment and Ecology (Environment). The final day, 29 October, is Public Day with free admission.
