Innovation helps bring home the bacon in Chongqing

Chongqing has introduced a smoke-free device to allow residents to once again make smoked bacon, after the traditional method was banned for contributing to air pollution.

The new environmentally friendly machine consists of three parts - a metal smoking box, plus cooling and purifying systems. The bacon is hung surrounded by smoke from burning cypress branches, and the smoke is cooled before it is purified and emitted into the air.

"The smoked bacon made by this machine can preserve the original taste and protect the environment," said Zhang Zhong, who owns a site designated for smoking meat.
