In recent years, the foul odor from garbage transfer stations has become a problem that troubles government departments, environmental sanitation workers, and the public. Yiqing Environmental Protection proposed the concept of "breathing garbage stations" in 2020, adopting a comprehensive solution technology of "reasonable sealing, air empowerment, deodorization and disinfection, intelligent monitoring" to make the garbage stations "invisible" and "eliminate" the odor of the garbage stations. Yiqing Environmental Protection believes that garbage comes from daily life and should also be integrated into daily life. The "Breathable Garbage Station" brings life to the garbage and equips it with a human "breathing" system. The foul odor gas inside the garbage station is treated by the "City Lung" Yilan Environmental Protection Catalytic Deodorization Equipment, which alternates the air circulation inside the station, allowing the garbage station to truly breathe.
