Once you consider bamboo, you in all probability do not consider the world’s longest bridge-and-tunnel sea crossing spanning 34 miles (55 km) and shuttling round 150,000 folks a day between Hong Kong and Macau.
You in all probability consider cute little roly-poly panda bears. And you would be proper, as bamboo makes up about 99% of a panda’s food regimen. An enormous panda will eat as a lot as 84 lb (38 kg) of bamboo per day. Leaves, stems, shoots and all.
It is a good factor for bamboo that it is one of many fastest-growing and sustainable plant species on the earth – Moso bamboo can develop as much as 35 inches (91 cm) per day. Do you know bamboo is not really a tree? It is grass … and it is a robust grass: Stronger than gentle metal (the stuff they make automotive components and constructing I-beams out of) by way of tensile power. Bamboo’s compressive power can be larger than that of concrete – about 7,000 psi versus customary concrete’s 4,000 psi. As robust as it’s, it additionally has wonderful elasticity and may bend considerably earlier than splintering. And it is extremely light-weight. It is principally nature’s multi-purpose plant – together with panda meals.
Its spectacular laundry record of properties make it a wonderful candidate for constructing materials. Even sea-spanning bridge infrastructure materials.
The Hong Kong-Zhuhai-Macao Bridge was accomplished in 2018. It spans the Zhujiang River Estuary within the South China Sea, connecting Hong Kong, Macau, and Zhuhai in Guangdong Province. The bridge shaves about 100 miles (160 km) off the journey from Hong Kong to Macau, the “Las Vegas of Asia.”

The substitute island that connects the bridge phase to the tunnel that successfully helps all of the day-to-day visitors has panorama platforms that have been floored utilizing bamboo-based composite panels. Overlaying about 215,278 sq. toes (20,000 sq m) in all, these bamboo panels have needed to endure a number of the most torturous circumstances Mom Nature can throw at them: the fixed batter of seawater, unrelenting solar, and the occasional hurricane thrown in for good measure. Seven years publish development, these sturdy, high-strength, eco-friendly panels are nonetheless standing the check of time.

China is the world’s chief within the bamboo biz, accounting for roughly 70% of world bamboo exports. The nation’s bamboo business is valued at round US$74 billion. This capacity of the grass to develop rapidly, its eco-friendliness, and its power make it helpful past chopsticks or just a tasty panda snack.
China’s developments in bamboo composites, like low-aldehyde/phenol adhesives and gentle pyrolytic strategies to take away contaminants whereas sustaining its cellulose construction make bamboo a number one renewable materials for development, not just for its resilience but additionally for its sustainability.
In 2023, China introduced a three-year plan to advertise “bamboo as an alternative of plastic,” to extend bamboo utilization by 20% by 2025 in an effort to scale back plastic waste. Which means extra bamboo in the whole lot from development to packaging. And by the seems to be of it, perhaps even in future bridges.
