The volatile organic compounds discharged by Bridgestone (Tianjin) Tire Co., Ltd. are listed in the key treatment projects of Tianjin “2015 Fresh Air Action Plan”. This company intends to invest RMB 38.01 Million Yuan to purchase 17 fume treatment facilities totally for the treatment of organic waste gas emitted in such procedures as banbury- ing, calendaring, extrusion and vulcanization.

It is learned that the technical transformation project is predicted to be completed in January of the next year, main- ly to assemble the gas-collecting hood in the sidewall ex- truder head, triangle rubber extruder head, compatible line extruder head and tread extruder head for collecting waste gas to the waste gas treatment device, and assemble a vent pipe in the rubber latex room for delivering the waste gas to the waste gas treatment device. There is a gas-collecting hood in the current vulcanizing workshop, and waste gas is discharged through the draught fan at the top of the work- shop. Finally, the waste gas collected in the gas-collecting hood is transported to the waste gas treatment device for disposal.
