BEIJING, July 14  -- China's Palace Museum, also known as the Forbidden City, has started promoting "zero waste" tours among tour guides and the public.

A training session was held Tuesday for tour guides who should encourage visitors to participate in garbage sorting and recycling during their tours.

The Palace Museum launched a "zero waste" program in January 2020 to work toward the goal of minimizing the amount of waste that would go through landfills or incineration.

A no-waste approach has been adopted for office work at the museum over last year.
