At 6.00am on September 12, 2013, Haier carried out the controlled demolition of an old 80m smokestack at Qingdao Haier Industrial Park. The smokestack was built two decades ago in 1993. According to projections, the decommissioning of the smokestack will cut sulfur dioxide emissions by 56.76 tons/year, equivalent to the amount of harmful gases that a 1580-acre forest can absorb in one year.
