A staffer explains to visitors about the Longgang Energy Ecological Park at the 2023 Shenzhen (International) Urban Environment and Landscape Industrial Exhibition, which opened at Shenzhen Convention and Exhibition Center in Futian District yesterday. Put into operation in 2019 in Longgang District, it is the largest single waste incineration and power generation plant in Shenzhen. Dubbed Shenzhen’s environmental guardian, it processes 5,100 metric tons of waste each day, one third of the city’s total. The exhibition, the country’s first expo featuring city appearance industry, will run through Friday.   Sun Yuchen
