Pollution in large cities is a big problem for many countries like Australia, China, United States of America and England. The Australian Federal Government looked into suggested causes of concern with the wood heating industry. These included:
1. Natural wood reserves running out
2. The excessive amount of carbon dioxide released into the atmosphere from wood burning
3. Smoke from combustion heaters on slow overnight burn cycle causing unpleasant smoke in residential and commercial areas
4. Working together with the Wood Heating Industry
The answers came when the Australian Wood Heating Industry paid for a report to look into the problems the Government had identified. Many specialists' expertise was used in compiling the report. The results were mixed and very interesting and not as bad as at first outlined. The non-issue was wood reserves potentially running out as the wood used in these heaters was mostly wasted in normal timber industry recovery. And the report also found that the timber industry is self-recovering.
Also the issue of too much carbon dioxide being released into the air was actually no more than is released from naturally rotting wood on the forest floor. However there was a problem with unpleasant smoke hanging around at night from stoves on slow overnight burn cycle. This was caused by burning wood on this cycle at reduced temperatures when there is limited air intake. This slow burn can produce very smelly, heavily laden smoke. Smoke that is full of unburnt saps and tars (otherwise known as "creosote"). So rectifying this problem became a priority with wood burning heaters.
New Standards of Emissions Control
The Australian Government, in conjunction with the Wood Heating Industry, decided to introduce legislation known as AS4013/1993, to set a maximum standard on the particulate emissions that cause the nuisance smoke. The limit as specified in Standard AS4013/1993 was to be no more than 5.5 grams of particulate to be released into the atmosphere per kilogram of wood burnt. The Wood Heating Industry met this standard and now all wood fired heaters available in Australia no longer produce nuisance smoke. This standard was updated to 4 grams per kilogram in 1999, and the Wood Heating Industry has agreed to further lower these emission standards to 2.5 grams per kilogram by December 2013.
