Bag filters: metal or plastic frames?
h4>Metal or plastic frame: Does this affect the filter quality?
No. The frame material has no influence on the performance of the pocket filter.
h4>Metal or plastic frame: Are there any disposal regulations?
Since the Closed Substance Cycle Waste Management Act came into force in 2006 (amendment from 2012), it is no longer possible to landfill waste with a high calorific value (> 6,000 KJ/kg) too easily.
Since then, all air filters have had to be disposed of via thermal treatment plants: The filters must be incinerated in waste incineration plants.
Since then, the presence of a metal frame has been unimportant. On the contrary: the increase in the recycling of waste often leads to a shortage of waste, so that existing recycling methods are often not available.
combustion capacities can no longer be filled and substances with a lower calorific value are increasingly also being burned.
Are there restrictions on the combustion of filters?
The only restriction in waste incineration is the content of the stored dusts. If particularly harmful dusts have been separated, which may occur in individual cases, e.g. with process air, a declaration as “particularly subject to monitoring, waste code 150202” may be issued.
In this case, not only are disposal costs considerably higher, but some incineration plants, which only have a permit to incinerate municipal waste, may not accept such substances.
Large quantities of filters should be disposed of by a qualified service company. As a rule, almost all pocket filters are then disposed of as “waste subject to monitoring (waste code 150 203)” in domestic waste incineration plants. The frame material used is completely irrelevant.
