In Jinan, China, authorities have installed the world`s largest inflatable dome spanning 20,000 square metres and standing 50 metres tall to reduce dust and noise pollution at construction sites. The transparent dome uses negative pressure and advanced air filtration to contain dust and provide clean air for workers, while allowing sunlight to reduce the need for artificial lighting.

Built without beams or support columns, the dome is easy to assemble, dismantle and move to new locations.

It also serves as a sound barrier, making nearby urban areas quieter during construction. It is part of China`s broader push for greener, more sustainable urban development. If successful, similar domes may be rolled out nationwide.
