If you think of bamboo, you probably don't think of the longest bridging and tunnel crossing of the world, which exceeds 55 km (around 150,000 people a day between Hong Kong and Macau).
You probably think of cute little Roly-Poly-Panda bears. And they were right because bamboo is about 99% of the diet of a panda. A huge panda will eat up to 84 lb (38 kg) bamboo a day. Leaves, stems, shots and everything.
For bamboo it is a good thing that one of the fastest growing and sustainable plant species in the world is-moso bamboo can grow up to 35 inches (91 cm). per day. Did you know that bamboo is actually not a tree? It is grass … and it is a strong grass: stronger than soft steel (the stuff you build and build i rays in terms of tensile strength). The compressive strength of bamboo is also higher than that of concrete – around 7,000 PSI compared to standard concrete 4,000 PSI. As strong as it is, it also has excellent elasticity and can bend considerably in front of the splinter. And It is incredibly light. Basically, it is the multi-purpose plant of the natural-panda food.
The impressive laundry list of real estate makes it an excellent candidate for building materials. Even sea voltage bridge infrastructure material.
The Hong Kong-Zhuhai-Macao-Bridge was completed in 2018. It extends over the mouth of the Zhujiang River in the South China Sea and Hong Kong, Macau and Zhuhai in the province of Guangdong. The bridge shaved over 160 km from the trip from Hong Kong to Macau, the “Las Vegas of Asia”, from Hong Kong to Macau.

The artificial island, which connects the bridge segment with the tunnel, which effectively supports the entire daily traffic, has landscape platforms, the bamboo -based composite plates. A total of 205,278 quadrat foot (a total of 20,000 m²) had to endure some of the most agonizing conditions that mother can throw nature on them: the constant dough made of sea water, relentless sun and occasionally row that is thrown well. Seven years after the construction, these long -lasting, high -strength and environmentally friendly panels still exist in the test of the time.

China is the world's leading provider of Bambusbiz and accounts for around 70% of global bamboo exports. The country's bamboo industry has a value of around 74 billion US dollars. This ability of grass to grow quickly, its environmental friendliness and its strength make it useful, over chopsticks or just a delicious panda snack.
China's progress in bamboo composite materials such as low-dehyd/phenol adhesives and mild pyrolytic techniques to remove contaminants and at the same time maintain its cellulose structure, make bamboo a leading renewable material for construction, not only for its resistance, but also for its sustainability.
In 2023, China announced a three -year plan to promote “bamboo instead of plastic” to increase bamboo utilization by 20% by 2025 to reduce plastic waste. That means more bamboo in everything, from construction to packaging. And through the appearance, maybe even in future bridges.
