Green Tech spotlighted: Breathing walls and smart chargers

Karin Lau

During a media tour at the 2026 Macao International Environmental Co-operation Forum & Exhibition (MIECF), exhibitors from Macau, Hong Kong, and mainland China unveiled cutting-edge solutions for carbon neutrality.

Hong Kong’s Karin Lau, executive at Star Affinity Ventures Limited and Cornell University alum, presented in the Zero Waste Circular Economy Exhibition Zone. Her standout innovation: CIONEXT™, billed as the world’s first carbon-capturing partition.

This “breathing exhibition” wall uses patented ion exchange technology to pull CO₂ directly from indoor air and convert it into sustainable materials, Lau explained. Like a real tree, the CIONEXT™ system captures CO₂ from ambient air and reduces its concentration, she said. A single unit drops CO₂ levels from 1,200 parts per million to under 600 ppm in minutes, with over 95% efficiency, equivalent to 20 large trees. Depending on the module size, it can capture as much CO₂ as 1,000 trees or more. According to the company, a single unit reduces CO₂ from 1,200 ppm to under 600 ppm in minutes, matching 20 large trees.

Shifting to electric vehicles, Gavin Bu, CEO of Syneric Technology (Macau) Company Limited, demonstrated the Mololo X in the Green Mobility Zone. Dubbed the “Captain Superpower,” the Mololo X turns a standard 7-kilowatt grid into 30 kilowatts for fast charging using low-input, high-output storage technology. It bypasses power limits with stackable modules, cuts EV charging time from seven hours to 1.6 hours, and reduces site costs for wider adoption.

In the Green and Low-Carbon Project Zone, Hailey Lei of Shenzhen CarbonMiner Technology (Group) Co. Ltd. highlighted Obrick, autoclaved aerated concrete bricks. The “exhaust-inhaling” blocks permanently lock CO₂ via omni-dimensional cement rock weathering, Lei detailed. Ten cubic meters of Obrick trap 0.5 tons of CO₂. In addition, the bricks are lightweight, earthquake-resistant, sound-dampening, insulating, and nationally certified green.
