Manufacturers are working to develop more environmentally friendly fireworks, due to environmental concerns and in an effort to rejuvenate the market hurt by firework display bans.

The alternative products are mostly made with improved black powder and new chemicals that contain less heavy metal and sulphur, reducing emission of harmful sulfide.

Setting off fireworks during the Lunar New Year is an age-old tradition in China, with ancient superstitions believing that light and sound scare away evil spirits. In more recent years, they're used to bring a festive atmosphere during the country's most important holiday.
Â
However, fireworks have been increasingly blamed for contributing to the country's smog problem, pushing local governments to implement measures forbidding or limiting firework displays.
Â
Rao Hui, chief engineer of the environment monitoring station of Nanchang City, said green fireworks can both satisfy the needs of environmental protection and reservation of traditional customs.
Â
Authorities should help strengthen the market demand for green fireworks by heightening public awareness of the merits of the products, he said.Â
