"50+ Expo 2018" was held at Hall 5E, Hong Kong Convention and Exhibition Centre from 6 to 8 July, 2018. “Food For Good” promoted green dining culture during the exhibition. We also collected food waste from exhibitors and converted the waste to organic compost on-site. Compost was given to visitors as well. We would like to thank the organizer, exhibitors, people managing the booths, volunteers and others for their support.
