The skyscrapers and buildings of the future could be made from cross-laminated timber (CLT) as more industry professionals recognize the benefits of building with CLT. The CLT offers faster construction than steel or concrete and produces less noise and mess during construction.
According to an article on Popular Science, the construction speed and noise disruption aren't what makes the CLT so appealing: it's the environmental benefits. Because the CLT is made from wood fragments in order to create the beams, smaller pieces of wood, slender trees, and even wood ravaged by pests like the pine beetle can be salvaged to make the timber instead of going to waste. In addition, the manufacturing techniques of steel and concrete emit carbon dioxide as a by-product of the process, which means that both steel and concrete have a huge carbon footprint. Wood, on the other hand, traps carbon dioxide.
Compare this to steel and concrete. "If we built a 20-story building out of cement and concrete, the process would result in...1,200 tons of carbon dioxide,” said architect Michael Green in a TED Talk. “If we did it in wood, in this solution, we'd sequester about 3,100 tons, for a net difference of 4,300 tons. That's the equivalent of about 900 cars removed from the road in one year."
