Diesel and Coal are...
the REAL reasons why smog is an issue in China.
Pork smoking would be a poor reason. They could fix much of the left over smoke with nothing more than an "afterburner" that simply re-burns the output of the smoker. Some chimney draft control would help a lot as well. Friction smokers don't need any chimney draft to the outdoors and are being used in many applications in the states for smoking foodstuffs
But even that minimal control will never happen in China as they don't use emission controls properly on anything. The diesel fuel is high sulphur and so is the coal so cars, homes and Industry just continue to put out the worst smog possible. Any "controls" that can be defeated, already have been. If you have seen the pictures, it looks like the "killer" smogs of the late 1800 in England.
Biting the hand that feeds IT
