At the Weda Bay hydrometallurgical project base, Huafei launched a 20 - day creative works collection contest themed "Revitalize the Old", which attracted a large number of employees to participate enthusiastically.The contestants made use of discarded materials such as plastic bottles, packaging boxes, waste cardboard boxes and metal parts, giving new life to these seemingly useless waste items.More than 50 works not only demonstrated practical functions but also had unique artistic beauty. While reducing resource waste, they also added a unique artistic flavor to daily life.
